wbinvd_on_all_cpus() is only defined on x86 it seems, plus we need to
include asm/smp.h here.

Subject: drm/i915/gem: Break out some shmem backend utils
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Break out some shmem backend utils for future reuse by the TTM backend:
shmem_alloc_st(), shmem_free_st() and __shmem_writeback() which we can
use to provide a shmem-backed TTM page pool for cached-only TTM
buffer objects.

Main functional change here is that we now compute the page sizes using
the dma segments rather than using the physical page address segments.

v2(Reported-by: kernel test robot <lkp@intel.com>)
    - Make sure we initialise the mapping on the error path in
      shmem_get_pages()

Subject: drm/i915/ttm: add tt shmem backend
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For cached objects we can allocate our pages directly in shmem. This
should make it possible(in a later patch) to utilise the existing
i915-gem shrinker code for such objects. For now this is still disabled.

v2(Thomas):
  - Add optional try_to_writeback hook for objects. Importantly we need
    to check if the object is even still shrinkable; in between us
    dropping the shrinker LRU lock and acquiring the object lock it could for
    example have been moved. Also we need to differentiate between
    "lazy" shrinking and the immediate writeback mode. Also later we need to
    handle objects which don't even have mm.pages, so bundling this into
    put_pages() would require somehow handling that edge case, hence
    just letting the ttm backend handle everything in try_to_writeback
    doesn't seem too bad.
v3(Thomas):
  - Likely a bad idea to touch the object from the unpopulate hook,
    since it's not possible to hold a reference, without also creating
    circular dependency, so likely this is too fragile. For now just
    ensure we at least mark the pages as dirty/accessed when called from the
    shrinker on WILLNEED objects.
  - s/try_to_writeback/shrinker_release_pages, since this can do more
    than just writeback.
  - Get rid of do_backup boolean and just set the SWAPPED flag prior to
    calling unpopulate.
  - Keep shmem_tt as lowest priority for the TTM LRU bo_swapout walk, since
    these just get skipped anyway. We can try to come up with something
    better later.
v4(Thomas):
  - s/PCI_DMA/DMA/. Also drop NO_KERNEL_MAPPING and NO_WARN, which
    apparently doesn't do anything with streaming mappings.
  - Just pass along the error for ->truncate, and assume nothing.

Subject: drm/i915: drop unneeded make_unshrinkable in free_object
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The comment here is no longer accurate, since the current shrinker code
requires a full ref before touching any objects. Also unset_pages()
should already do the required make_unshrinkable() for us, if needed,
which is also nicely balanced with set_pages().

Subject: drm/i915/ttm: move shrinker management into adjust_lru
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We currently just evict lmem objects to system memory when under memory
pressure. For this case we might lack the usual object mm.pages, which
effectively hides the pages from the i915-gem shrinker, until we
actually "attach" the TT to the object, or in the case of lmem-only
objects it just gets migrated back to lmem when touched again.

For all cases we can just adjust the i915 shrinker LRU each time we also
adjust the TTM LRU. The two cases we care about are:

  1) When something is moved by TTM, including when initially populating
     an object. Importantly this covers the case where TTM moves something from
     lmem <-> smem, outside of the normal get_pages() interface, which
     should still ensure the shmem pages underneath are reclaimable.

  2) When calling into i915_gem_object_unlock(). The unlock should
     ensure the object is removed from the shinker LRU, if it was indeed
     swapped out, or just purged, when the shrinker drops the object lock.

v2(Thomas):
  - Handle managing the shrinker LRU in adjust_lru, where it is always
    safe to touch the object.
v3(Thomas):
  - Pretty much a re-write. This time piggy back off the shrink_pin
    stuff, which actually seems to fit quite well for what we want here.
v4(Thomas):
  - Just use a simple boolean for tracking ttm_shrinkable.
v5:
  - Ensure we call adjust_lru when faulting the object, to ensure the
    pages are visible to the shrinker, if needed.
  - Add back the adjust_lru when in i915_ttm_move (Thomas)
v6(Reported-by: kernel test robot <lkp@intel.com>):
  - Remove unused i915_tt

This should let us do an accelerated copy directly to the shmem pages
when temporarily moving lmem-only objects, where the i915-gem shrinker
can later kick in to swap out the pages, if needed.

Subject: drm/i915/selftests: Increase timeout in requests perf selftest
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

perf_parallel_engines is micro benchmark to test i915 request
scheduling. The test creates a thread per physical engine and submits
NOP requests and waits the requests to complete in a loop. In execlists
mode this works perfectly fine as powerful CPU has enough cores to feed
each engine and process the CSBs. With GuC submission the uC gets
overwhelmed as all threads feed into a single CTB channel and the GuC
gets bombarded with CSBs as contexts are immediately switched in and out
on the engines due to the zero runtime of the requests. When the GuC is
overwhelmed scheduling of contexts is unfair due to the nature of the
GuC scheduling algorithm. This behavior is understood and deemed
acceptable as this micro benchmark isn't close to real world use case.
Increasing the timeout of wait period for requests to complete. This
makes the test understand that is ok for contexts to get starved in this
scenario.

A future patch / cleanup may just delete these micro benchmark tests as
they basically mean nothing. We care about real workloads not made up
ones.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Update live.evict to wait on last request and idle GPU after each loop.
This not only enhances the test to fill the GGTT on each engine class
but also avoid timeouts from igt_flush_test when using GuC submission.
igt_flush_test (idle GPU) can take a long time with GuC submission if
losts of contexts are created due to H2G / G2H required to destroy
contexts.

From: Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com>

Subject: drm/i915/pmu: Connect engine busyness stats from GuC to pmu

With GuC handling scheduling, i915 is not aware of the time that a
context is scheduled in and out of the engine. Since i915 pmu relies on
this info to provide engine busyness to the user, GuC shares this info
with i915 for all engines using shared memory. For each engine, this
info contains:

- total busyness: total time that the context was running (total)
- id: id of the running context (id)
- start timestamp: timestamp when the context started running (start)

At the time (now) of sampling the engine busyness, if the id is valid
(!= ~0), and start is non-zero, then the context is considered to be
active and the engine busyness is calculated using the below equation

	engine busyness = total + (now - start)

All times are obtained from the gt clock base. For inactive contexts,
engine busyness is just equal to the total.

The start and total values provided by GuC are 32 bits and wrap around
in a few minutes. Since perf pmu provides busyness as 64 bit
monotonically increasing values, there is a need for this implementation
to account for overflows and extend the time to 64 bits before returning
busyness to the user. In order to do that, a worker runs periodically at
frequency = 1/8th the time it takes for the timestamp to wrap. As an
example, that would be once in 27 seconds for a gt clock frequency of
19.2 MHz.

Note:
There might be an over-accounting of busyness due to the fact that GuC
may be updating the total and start values while kmd is reading them.
(i.e kmd may read the updated total and the stale start). In such a
case, user may see higher busyness value followed by smaller ones which
would eventually catch up to the higher value.

v2: (Tvrtko)
- Include details in commit message
- Move intel engine busyness function into execlist code
- Use union inside engine->stats
- Use natural type for ping delay jiffies
- Drop active_work condition checks
- Use for_each_engine if iterating all engines
- Drop seq locking, use spinlock at GuC level to update engine stats
- Document worker specific details

v3: (Tvrtko/Umesh)
- Demarcate GuC and execlist stat objects with comments
- Document known over-accounting issue in commit
- Provide a consistent view of GuC state
- Add hooks to gt park/unpark for GuC busyness
- Stop/start worker in gt park/unpark path
- Drop inline
- Move spinlock and worker inits to GuC initialization
- Drop helpers that are called only once

v4: (Tvrtko/Matt/Umesh)
- Drop addressed opens from commit message
- Get runtime pm in ping, remove from the park path
- Use cancel_delayed_work_sync in disable_submission path
- Update stats during reset prepare
- Skip ping if reset in progress
- Explicitly name execlists and GuC stats objects
- Since disable_submission is called from many places, move resetting
  stats to intel_guc_submission_reset_prepare

v5: (Tvrtko)
- Add a trylock helper that does not sleep and synchronize PMU event
  callbacks and worker with gt reset

v6: (CI BAT failures)
- DUTs using execlist submission failed to boot since __gt_unpark is
  called during i915 load. This ends up calling the GuC busyness unpark
  hook and results in kick-starting an uninitialized worker. Let
  park/unpark hooks check if GuC submission has been initialized.
- drop cant_sleep() from trylock helper since rcu_read_lock takes care
  of that.

v7: (CI) Fix igt@i915_selftest@live@gt_engines
- For GuC mode of submission the engine busyness is derived from gt time
  domain. Use gt time elapsed as reference in the selftest.
- Increase busyness calculation to 10ms duration to ensure batch runs
  longer and falls within the busyness tolerances in selftest.

v8:
- Use ktime_get in selftest as before
- intel_reset_trylock_no_wait results in a lockdep splat that is not
  trivial to fix since the PMU callback runs in irq context and the
  reset paths are tightly knit into the driver. The test that uncovers
  this is igt@perf_pmu@faulting-read. Drop intel_reset_trylock_no_wait,
  instead use the reset_count to synchronize with gt reset during pmu
  callback. For the ping, continue to use intel_reset_trylock since ping
  is not run in irq context.

- GuC PM timestamp does not tick when GuC is idle. This can potentially
  result in wrong busyness values when a context is active on the
  engine, but GuC is idle. Use the RING TIMESTAMP as GPU timestamp to
  process the GuC busyness stats. This works since both GuC timestamp and
  RING timestamp are synced with the same clock.

- The busyness stats may get updated after the batch starts running.
  This delay causes the busyness reported for 100us duration to fall
  below 95% in the selftest. The only option at this time is to wait for
  GuC busyness to change from idle to active before we sample busyness
  over a 100us period.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The scratch page is directly visible in the users address space, and
while this is forced as CACHE_LLC, by the kernel, we still have to
contend with things like "Bypass-LLC" MOCS. So just flush no matter
what.

v2(Thomas):
  - Make sure we use drm_clflush_virt_range here, in case clflush support
    is missing.

Normal users shouldn't be hitting this, likely this would indicate a
userspace bug. So don't bother caching, which should be safe now that we
manually flush the page.

Subject: drm/i915: Enable WaProgramMgsrForCorrectSliceSpecificMmioReads for
 Gen9
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This implements WaProgramMgsrForCorrectSliceSpecificMmioReads which
was omitted by mistake from Gen9 documentation, while it is actually
applicable to fused off parts.

Workaround consists of making sure MCR packet control register is
programmed to point to enabled slice/subslice pair before doing any
MMIO reads from the affected registers.

Failure do to this can result in complete system hangs when running
certain workloads. Two known cases which can cause system hangs are:

1. "test_basic progvar_prog_scope_uninit" test which is part of
    Khronos OpenCL conformance suite
    (https://github.com/KhronosGroup/OpenCL-CTS) with the Intel
    OpenCL driver (https://github.com/intel/compute-runtime).

2. VP8 media hardware encoding using the full-feature build of the
    Intel media-driver (https://github.com/intel/media-driver) and
    ffmpeg.

For the former case patch was verified to fix the hard system hang
when executing the OCL test on Intel Pentium CPU 6405U which contains
fused off GT1 graphics.

Subject: drm/i915: Introduce refcounted sg-tables
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As we start to introduce asynchronous failsafe object migration,
where we update the object state and then submit asynchronous
commands we need to record what memory resources are actually used
by various part of the command stream. Initially for three purposes:

1) Error capture.
2) Asynchronous migration error recovery.
3) Asynchronous vma bind.

At the time where these happens, the object state may have been updated
to be several migrations ahead and object sg-tables discarded.

In order to make it possible to keep sg-tables with memory resource
information for these operations, introduce refcounted sg-tables that
aren't freed until the last user is done with them.

The alternative would be to reference information sitting on the
corresponding ttm_resources which typically have the same lifetime as
these refcountes sg_tables, but that leads to other awkward constructs:
Due to the design direction chosen for ttm resource managers that would
lead to diamond-style inheritance, the LMEM resources may sometimes be
prematurely freed, and finally the subclassed struct ttm_resource would
have to bleed into the asynchronous vma bind code.

v3:
- Address a number of style issues (Matthew Auld)
v4:
- Dont check for st->sgl being NULL in i915_ttm_tt__shmem_unpopulate(),
  that should never happen. (Matthew Auld)
v5:
- Fix a Potential double-free (Matthew Auld)

From 3ea355b234d7d3e543b89e55c66d57db50ef1581 Mon Sep 17 00:00:00 2001
From: Matthew Auld <matthew.auld@intel.com>
Date: Wed, 27 Oct 2021 17:18:10 +0100
Subject: drm/i915/clflush: fixup handling of cache_dirty
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In theory if clflush_work_create() somehow fails here, and we don't yet
have mm.pages populated then we end up resetting cache_dirty, which is
likely wrong, since that will potentially skip the flush-on-acquire, if
it was needed.

It looks like intel_user_framebuffer_dirty() can arrive here before the
pages are populated.

v2(Thomas):
  - Move setting cache_dirty out of the async portion, also add a
    comment for why that should still be safe.
v3:
  - Add Thomas' irc r-b

Subject: drm/i915/clflush: disallow on discrete
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We seem to have an unfortunate issue where we arrive from:

    i915_gem_object_flush_if_display+0x86/0xd0 [i915]
    intel_user_framebuffer_dirty+0x1a/0x50 [i915]
    drm_mode_dirtyfb_ioctl+0xfb/0x1b0

which can be before the pages are populated(and pinned for display), and
so i915_gem_object_has_struct_page() might still return true, as per the
ttm backend. We could re-order the later get_pages() call here, but
since on discrete everything should already be coherent, with the
exception of the display engine, and even there display surfaces must be
allocated in device local-memory anyway, so there should in theory be no
conceivable reason to ever call i915_gem_clflush_object() on discrete.

Move it next to its partner in crime; gpu_write_needs_clflush. For
better readability lets keep gpu vs cpu at least in the same file.

Subject: drm/i915: Track media IP stepping separated from GT
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Graphics and media IPs can have different stepping so a new field is
needed in intel_step_info.

The next patch will take care of rename gt_step to graphics_step.

Subject: drm/i915: Rename GT_STEP to GRAPHICS_STEP
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As now graphics and media can have different steppings this patch is
renaming all _GT_STEP macros to _GRAPHICS_STEP.

Future platforms will properly choose between _MEDIA_STEP and
_GRAPHICS_STEP for each new workaround.

From 292e4fb05f14d54c90cb165335c6d4dfaf1cfb32 Mon Sep 17 00:00:00 2001
From: Vinay Belgaumkar <vinay.belgaumkar@intel.com>

Subject: drm/i915/guc/slpc: Define and initialize boost frequency

Define helpers and struct members required to record boost info.
Boost frequency is initialized to RP0 at SLPC init. Also define num_waiters
which can track the pending boost requests.

Boost will be done by scheduling a worker thread. This will avoid
the need to make H2G calls inside an interrupt context. Initialize the
worker function during SLPC init as well. Had to move intel_guc_slpc_init
a few lines below to accommodate this.

v2: Add a workqueue to handle waitboost
v3: Code review comments (Ashutosh)

Subject: drm/i915/guc/slpc: Add waitboost functionality for SLPC

Add helper in RPS code for handling SLPC and non-SLPC paths.
When boost is requested in the SLPC path, we can ask GuC to ramp
up the frequency req by setting the minimum frequency to boost freq.
Reset freq back to the min softlimit when there are no more waiters.

v2: Schedule a worker thread which can boost freq from within
an interrupt context as well.

v3: No need to check against requested freq before scheduling boost
work (Ashutosh)

Subject: drm/i915/guc/slpc: Update boost sysfs hooks for SLPC

Add a helper to sort through the SLPC/RPS paths of get/set methods.
Boost frequency will be modified as long as it is within the constraints
of RP0 and if it is different from the existing one. We will set min
freq to boost only if there is at least one active waiter.

v2: Add num_boosts to guc_slpc_info and changes for worker function
v3: Review comments (Ashutosh)

Subject: drm/i915: fixup dma_fence_wait usage
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

dma_fence_wait expects a boolean for whether it should be interruptible,
not a timeout value.

Subject: drm/i915/ttm: Reorganize the ttm move code
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We are about to introduce failsafe- and asynchronous migration and
ttm moves.
This will add complexity and code to the TTM move code so it makes sense
to split it out to a separate file to make the i915 TTM code easer to
digest.
Split the i915 TTM move code out and since we will have to change the name
of the gpu_binds_iomem() and cpu_maps_iomem() functions anyway,
we alter the name of gpu_binds_iomem() to i915_ttm_gtt_binds_lmem() which
is more reflecting what it is used for.
With this we also add some more documentation. Otherwise there should be
no functional change.

From 2b0a750caf332a24f62f6960820d24d885f2efc2 Mon Sep 17 00:00:00 2001
From: Thomas Hellström <thomas.hellstrom@linux.intel.com>

Subject: drm/i915/ttm: Failsafe migration blits
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If the initial fill blit or copy blit of an object fails, the old
content of the data might be exposed and read as soon as either CPU- or
GPU PTEs are set up to point at the pages.

Intercept the blit fence with an async callback that checks the
blit fence for errors and if there are errors performs an async cpu blit
instead. If there is a failure to allocate the async dma_fence_work,
allocate it on the stack and sync wait for the blit to complete.

Add selftests that simulate gpu blit failures and failure to allocate
the async dma_fence_work.

A previous version of this pach used dma_fence_work, now that's
opencoded which adds more code but might lower the latency
somewhat in the common non-error case.

v3:
- Style fixes (Matthew Auld)
v4:
- Use "#if IS_ENABLED()" instead of #ifdef (Matthew Auld)
v5:
- Fix an issue where we, if the dependency was already signaled, might
  end up waiting for a memcpy fence that would never signal.
v6:
- Add a missing i915_ttm_memcpy_release() (Matthew Auld)

Subject: drm/i915/selftests: Rework context handling in hugepages selftests

In the next commit, we don't evict when refcount = 0, so we need to
call drain freed objects, because we want to pin new bo's in the same
place, causing a test failure.

Furthermore, since each subtest is separated, it's a lot better to use
i915_live_selftests, so each subtest starts with a clean slate, and a
clean address space.

v2(Reported-by: kernel test robot <lkp@intel.com>):
  - Make hugepage_ctx static.

Subject: drm/i915/resets: Don't set / test for per-engine reset bits with GuC
 submission

Don't set, test for, or clear per-engine reset bits with GuC submission
as the GuC owns the per engine resets not the i915. Setting, testing
for, and clearing these bits is causing issues with the hangcheck
selftest. Rather than change to test to not use these bits, rip the use
of these bits out from the reset code.

Subject: drm/i915/guc: Refcount context during error capture

When i915 receives a context reset notification from GuC, it triggers
an error capture before resetting any outstanding requsts of that
context. Unfortunately, the error capture is not a time bound
operation. In certain situations it can take a long time, particularly
when multiple large LMEM buffers must be read back and eoncoded. If
this delay is longer than other timeouts (heartbeat, test recovery,
etc.) then a full GT reset can be triggered in the middle.

That can result in the context being reset by GuC actually being
destroyed before the error capture completes and the GuC submission
code resumes. Thus, the GuC side can start dereferencing stale
pointers and Bad Things ensue.

So add a refcount get of the context during the entire reset
operation. That way, the context can't be destroyed part way through
no matter what other resets or user interactions occur.

v2:
 (Matthew Brost)
  - Update patch to work with async error capture
v3:
 (Matthew Brost)
  - Drop async capture support as that hasn't landed yet

Gem-TTM objects that are backed by shmem might have populated

For such objects, identified by having the
_SELF_MANAGED_SHRINK_LIST set, make sure they end up on the

Subject: drm/i915/selftests: Use clear_and_wake_up_bit() for the per-engine
 reset bitlocks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some selftests assume that nothing will attempt to grab these bitlocks
while they are held by the selftests. With GuC, for example, that is
not true because the hanging workloads may cause the GuC code to attempt
to grab them for a global reset, and that may cause it to end up
sleeping on the bit never waking up. Regardless whether that will be
the final solution for GuC, use clear_and_wake_up_bit() pending a more
thorough investigation on how this should be handled moving forward.

To be clear this needs to be a temporary solution. If we can't find
an in-kernel locking primitive to use here, we should at the very least
add lockdep annotation to these bitlocks with a thorough explanation
as to why we need to use bits.

v3:
- Use GEM_BUG_ON(test_and_set_bit()) rather than set_bit() to verify
  the assumption that nothing is holding the reset locks when we
  attempt to grab them. (Chris Wilson)

Subject: drm/i915: rework some irq functions to take intel_gt as argument

We'll be adding multi-tile support soon; on multi-tile platforms
interrupts are per-tile and every tile has the full set of
interrupt registers.

In this commit we start passing intel_gt instead of dev_priv for the
functions that are related to Xe_HP irq handling. Right now we're still
passing tile 0 everywhere, but in later patches we'll start actually
passing the correct tile.

Subject: drm/i915/ttm: Fix illegal addition to shrinker list
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There's a small window of opportunity during which the adjust_lru()
function can be called with a GEM refcount of zero from the TTM
eviction code. This results in a kernel BUG().

Ensure that we don't attempt to modify the GEM shrinker lists unless
we have a GEM refcount.

Subject: drm/i915/dg2: Program recommended HW settings

The bspec's performance guide suggests programming specific values into
a few registers for optimal performance.  Although these aren't
workarounds, it's easiest to handle them inside the GT workaround
functions (which will also ensure that the values set here are properly
melded with other bits in the same registers that _are_ set by
workarounds).

Bspec: 68331, 45395

Subject: drm/i915/guc/slpc: Check GuC status before freq boost

It's possible that i915 might get wedged between a boost
and un-boost. Validate the i915-GuC connection before trying
to send a H2G to change the min frequency.

Subject: drm/i915: Don't read query SSEU for non-existent slice 0 on old
 platforms

Pre-HSW platforms don't use the gt SSEU structures; this means that
calling intel_sseu_get_subslices() on slice 0 for these platforms will
trip a GEM_BUG_ON(slice >= sseu->max_slices) warning.

Let's move the DSS lookup for a DG2 workaround into a helper function
that will only get called after we've already decided that we're on a
DG2 platform.

Subject: drm/i915: Skip error capture when wedged on init

Trying to capture uninitialised engines when we wedged on init ends in
tears. Skip that together with uC capture, since failure to initialise the
latter can actually be one of the reasons for wedging on init.

v2:
 * Use i915_disable_error_state when wedging on init/fini.

v3:
 * Handle mock tests.

From: Graham Sider <Graham.Sider@amd.com>
Date: Tue, 19 Oct 2021 13:28:45 -0400
Subject: drm/amdkfd: remove kgd_dev declaration and initialization

Completes removal of kgd_dev. Direct references to amdgpu_device objects
should now be used instead.

From: Evan Quan <evan.quan@amd.com>

Subject: drm/amdgpu: use generic fb helpers instead of setting up AMD own's.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With the shadow buffer support from generic framebuffer emulation, it's
possible now to have runpm kicked when no update for console.

Subject: drm/amd/display: Add helper for blanking all dp displays

[Why & How]
1. The code to blank all dp display have been called many times,
so add helpers in dc_link to make it more concise.
2. Add some check to fix the dmesg errors at boot and resume from S3
on dcn3.1 during DQE's promotion test.

Subject: drm/amd/display: Pass panel inst to a PSR command

[why]
PSR set power command wasn't setting panel instance
and command version which caused both streams
to overwrite the same PSR state.
[how]
Pass panel instance to the set power command function
and to DMUB and set command version enum

Subject: drm/amd/display: Fix RGB MPO underflow with multiple displays

[WHY]
With RGB MPO enabled, playing a video with multiple displays connected
results in underflow when closing the video window

[HOW]
Reverted the old change to fix this problem, which prevented pipe splits
for multiple display configurations and caused high MCLK speeds during
idle. Added a two step call to dc_update_planes_and_stream, first time
with pipe split disabled and the second time with pipe split enabled,
which fixed the underflow issue

Subject: drm/amd/display: Use link_enc_cfg API for queries.

[Why]
The link_enc_cfg API operates in one of two modes depending on the stage
of application of dc_state to hardware. The API is the safest way to
query link encoder assignments.

[How]
Use results of link encoder assignment query using link_enc_cfg API.

Subject: drm/amd/display: Fix detection of aligned DMUB firmware meta info

[Why]
A built firmware binary may be aligned to 16-bytes with padding at the
end as necessary. In the case that padding was applied the meta info
will not be detected correctly and we won't be able to allocate the
appropriate firmware and tracebuffer sizes.

[How]
To maintain compatibility with already released firmware where this
occurs we need to try every meta offset from 0..15 inclusive.

Extract out the meta info checker into a helper function that's called
for each of these offsets and exit early when we've found it.

Subject: drm/amd/display: fix stale info in link encoder assignment

[Why]
The link encoder assignment leaves the old stream data when it was
unassigned. When the clear encoder assignment is called, it based on the
old stale data to access the de-allocated stream.

[How]
There should be no need to explicitly clean up the link encoder
assignment if the unassign loop does the work properly, the loop should
base on the current state to clean up the assignment.

Also, the unassignment should better clean up the values in the
assignement slots as well.

Subject: drm/amd/display: retain/release stream pointer in link enc table

[why]
At every reference to stream pointer, we need to increment/decrement the
kref_count.  Not doing so will result in invalid stream pointer still
alive after hibernate cycle.

[how]
Call stream retain/release whenever the link encoder assignment is set
to true/false since it indicates if we want to reference the stream
pointer or not.

Subject: drm/amd/display: Add hpd pending flag to indicate detection of new
 hpd

[Why]
For dpia link, link->hpd_status indicates current state, but driver
fails to capture hpd transitions in certain scenarios such as during
link training.

[How]
Added link->hpd_pending flag that captures arrival of new hpd.

Subject: drm/amd/display: Initialise encoder assignment when initialising
 dc_state

[Why]
Link encoder assignment tracking variables need to be (re)initialised
whenever dc_state is (re)initialised. Otherwise variables used for
dynamic encoder assignment (especially the link encoder availability
pool) are out of sync with dc_state and future encoder assignments are
invalid.

[How]
Initialise encoder assignment variables when creating new dc_state
resource.

Subject: drm/amd/display: Wait for ACK for INBOX0 HW Lock

[Why]
In DC we want to wait for the INBOX0 HW Lock command to ACK before
continuing. This is to ensure that the lock has been successfully
acquired before programming HW in DC.

[How]
Add interfaces to send messages on INBOX0, poll for their completation
and clear the ack.

Subject: drm/amdkfd: replace asic_family with asic_type

asic_family was a duplicate of asic_type, both of type amd_asic_type.
Replace all instances of device_info->asic_family with adev->asic_type
and remove asic_family from device_info.

From 48c19a95f15e787bc46b274129da37bce06df259 Mon Sep 17 00:00:00 2001
From: Perry Yuan <Perry.Yuan@amd.com>
Date: Thu, 28 Oct 2021 06:05:42 -0400
Subject: drm/amd/pm: add GFXCLK/SCLK clocks level print support for APUs

add support that allow the userspace tool like RGP to get the GFX clock
value at runtime, the fix follow the old way to show the min/current/max
clocks level for compatible consideration.

=== Test ===
$ cat /sys/class/drm/card0/device/pp_dpm_sclk
0: 200Mhz *
1: 1100Mhz
2: 1600Mhz

then run stress test on one APU system.
$ cat /sys/class/drm/card0/device/pp_dpm_sclk
0: 200Mhz
1: 1040Mhz *
2: 1600Mhz

The current GFXCLK value is updated at runtime.

Subject: drm/mediatek: Use mailbox rx_callback instead of cmdq_task_cb

rx_callback is a standard mailbox callback mechanism and could cover the
function of proprietary cmdq_task_cb, so use the standard one instead of
the proprietary one.

Subject: drm/mediatek: Remove the pointer of struct cmdq_client

In mailbox rx_callback, it pass struct mbox_client to callback
function, but it could not map back to mtk_drm_crtc instance
because struct cmdq_client use a pointer to struct mbox_client:

struct cmdq_client {
	struct mbox_client client;
	struct mbox_chan *chan;
};

struct mtk_drm_crtc {
	/* client instance data */
	struct cmdq_client *cmdq_client;
};

so remove the pointer of struct cmdq_client and let mtk_drm_crtc
instance define cmdq_client as:

struct mtk_drm_crtc {
	/* client instance data */
	struct cmdq_client cmdq_client;
};

and in rx_callback function, use struct mbox_client to get
struct mtk_drm_crtc.

CMDQ is used to update display register in vblank period, so
it should be execute in next 2 vblank. One vblank interrupt
before send message (occasionally) and one vblank interrupt
after cmdq done. If it fail to execute in next 3 vblank,

Subject: drm/aspeed: Fix vga_pw sysfs output

Before the drm driver had support for this file there was a driver that
exposed the contents of the vga password register to userspace. It would
present the entire register instead of interpreting it.

The drm implementation chose to mask of the lower bit, without explaining
why. This breaks the existing userspace, which is looking for 0xa8 in
the lower byte.

Change our implementation to expose the entire register.

Subject: drm/i915: move the pre_pin earlier
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In intel_context_do_pin_ww, when calling into the pre_pin hook(which is
passed the ww context) it could in theory return -EDEADLK(which is very
likely with debug kernels), once we start adding more ww locking in there,
like in the next patch. If so then we need to be mindful of having to
restart the do_pin at this point.

If this is the kernel_context, or some other early in-kernel context
where we have yet to setup the default_state, then we always inhibit the
context restore, and instead rely on the delayed active_release to set
the CONTEXT_VALID_BIT for us(if we even care), which should indicate
that we have context switched away, and that our newly saved context
state should now be valid. However, since we currently grab the active
reference before the potential ww dance, we can end up setting the
CONTEXT_VALID_BIT much too early, if we need to backoff, and then upon
re-trying the do_pin, we could potentially cause the hardware to
incorrectly load some garbage context state when later context switching
to that context, but at the very least this will trigger the
GEM_BUG_ON() in __engine_unpark. For now let's just move any ww dance
stuff prior to arming the active reference.

For normal user contexts this shouldn't be a concern, since we should
already have the default_state ready when initialising the lrc state,
and so there should be no concern with active_release somehow
prematurely setting the CONTEXT_VALID_BIT.

v2(Thomas):
  - Also re-order the onion unwind

Subject: drm/i915: Create a dummy object for gen6 ppgtt

We currently have to special case vma->obj being NULL because
of gen6 ppgtt and mock_engine. Fix gen6 ppgtt, so we may soon
be able to remove a few checks. As the object only exists as
a fake object pointing to ggtt, we have no backing storage,
so no real object is created. It just has to look real enough.

Also kill pin_mutex, it's not compatible with ww locking,
and we can use the vm lock instead.

v2:
  - Drop IS_SHRINKABLE and shorten overly long line
v3:
  - Checkpatch fix for alignment

Subject: drm/i915: Create a full object for mock_ring, v2.

This allows us to finally get rid of all the assumptions that vma->obj
is NULL.

Changes since v1:
- Ensure the mock_ring vma is pinned to prevent a fault.
- Pin it high to avoid failure in evict_for_vma selftest.

Subject: drm/msm/a6xx: Allocate enough space for GMU registers

In commit 142639a52a01 ("drm/msm/a6xx: fix crashstate capture for
A650") we changed a6xx_get_gmu_registers() to read 3 sets of
registers. Unfortunately, we didn't change the memory allocation for
the array. That leads to a KASAN warning (this was on the chromeos-5.4
kernel, which has the problematic commit backported to it):

Subject: drm/msm: Fix mmap to include VM_IO and VM_DONTDUMP

In commit 510410bfc034 ("drm/msm: Implement mmap as GEM object
function") we switched to a new/cleaner method of doing things. That's
good, but we missed a little bit.

Before that commit, we used to _first_ run through the
drm_gem_mmap_obj() case where `obj->funcs->mmap()` was NULL. That meant
that we ran:

  vma->vm_flags |= VM_IO | VM_PFNMAP | VM_DONTEXPAND | VM_DONTDUMP;
  vma->vm_page_prot = pgprot_writecombine(vm_get_page_prot(vma->vm_flags));
  vma->vm_page_prot = pgprot_decrypted(vma->vm_page_prot);

...and _then_ we modified those mappings with our own. Now that
`obj->funcs->mmap()` is no longer NULL we don't run the default
code. It looks like the fact that the vm_flags got VM_IO / VM_DONTDUMP
was important because we're now getting crashes on Chromebooks that
use ARC++ while logging out. Specifically a crash that looks like this
(this is on a 5.10 kernel w/ relevant backports but also seen on a
5.15 kernel):

Let's add the two flags back in.

While we're at it, the fact that we aren't running the default means
that we _don't_ need to clear out VM_PFNMAP, so remove that and save
an instruction.

NOTE: it was confirmed that VM_IO was the important flag to fix the
problem I was seeing, but adding back VM_DONTDUMP seems like a sane
thing to do so I'm doing that too.

Subject: drm/msm: Fix wait_fence submitqueue leak

We weren't dropping the submitqueue reference in all paths.  In
particular, when the fence has already been signalled. Split out
a helper to simplify handling this in the various different return
paths.

Subject: drm/msm: Restore error return on invalid fence

When converting to use an idr to map userspace fence seqno values back
to a dma_fence, we lost the error return when userspace passes seqno
that is larger than the last submitted fence.  Restore this check.

Mesa attempts to allocate a cached-coherent buffer in order to determine
if cached-coherent is supported.  Resulting in seeing this error message
once per process with newer mesa.  But no reason for this to be more
than a debug msg.

spinlock inside __update_guc_busyness_stats.

Subject: drm/msm/dsi: set default num_data_lanes

If "data_lanes" property of the dsi output endpoint is missing in
the DT, num_data_lanes would be 0 by default, which could cause
dsi_host_attach() to fail if dsi->lanes is set to a non-zero value
by the bridge driver.

According to the binding document of msm dsi controller, the
input/output endpoint of the controller is expected to have 4 lanes.
So let's set num_data_lanes to 4 by default.

Subject: drm/msm/dp: Avoid unpowered AUX xfers that caused crashes

If you happened to try to access `/dev/drm_dp_aux` devices provided by
the MSM DP AUX driver too early at bootup you could go boom. Let's
avoid that by only allowing AUX transfers when the controller is
powered up.

Specifically the crash that was seen (on Chrome OS 5.4 tree with
relevant backports):
  Kernel panic - not syncing: Asynchronous SError Interrupt
  CPU: 0 PID: 3131 Comm: fwupd Not tainted 5.4.144-16620-g28af11b73efb #1
  Hardware name: Google Lazor (rev3+) with KB Backlight (DT)
  Call trace:

   drm_dp_dpcd_read+0x64/0x10c
   auxdev_read_iter+0xd4/0x1c4

I did a little bit of tracing and found that:
* We register the AUX device very early at bootup.
* Power isn't actually turned on for my system until
  hpd_event_thread() -> dp_display_host_init() -> dp_power_init()
* You can see that dp_power_init() calls dp_aux_init() which is where
  we start allowing AUX channel requests to go through.

In general this patch is a bit of a bandaid but at least it gets us
out of the current state where userspace acting at the wrong time can
fully crash the system.
* I think the more proper fix (which requires quite a bit more
  changes) is to power stuff on while an AUX transfer is
  happening. This is like the solution we did for ti-sn65dsi86. This
  might be required for us to move to populating the panel via the
  DP-AUX bus.
* Another fix considered was to dynamically register / unregister. I
  tried that at <https://crrev.com/c/3169431/3> but it got
  ugly. Currently there's a bug where the pm_runtime() state isn't
  tracked properly and that causes us to just keep registering more
  and more.

Subject: drm/amd/display: Only flush delta from last command execution

[Why]
We're currently flushing commands that had been previously been
flushed or are currently being processed by the DMCUB when we don't
immediately wait for idle after command execution.

[How]
Avoiding reflushing the data by keeping track of the last wptr.

We'll treat this as the actual rptr by creating a copy of the inbox
and modifying the copy's rptr.

Subject: drm/amd/display: Code change for DML isolation

[why]
DML itself is SW only, putting the logic as part of resource makes it
hw dependent and thus impossible to compile separately from dc.
Separate compilation is critical for unit testing as well as bbox tool
development

[how]
create new dml wrapper.
Copy logic from the validation functions into dml wrapper as base
implementation. Dml wrapper has internal/static implementations
for all helpers, and does not reference other functions.
It may reference dc structures/types for convenience.

This change now has all the changes for DML isolation squashed into
one.

From 2665f63a7364633ad90b2c58167ed7ae224e5d33 Mon Sep 17 00:00:00 2001
From: Mikita Lipski <mikita.lipski@amd.com>
Date: Wed, 20 Oct 2021 08:51:04 -0400
Subject: drm/amd/display: Enable DSC over eDP

[why]
- Adding a DM interface to enable DSC over eDP on Linux
- DSC over eDP will allow to power savings by reducing
the bandwidth required to support panel's modes
- Apply link optimization algorithm to reduce link bandwidth
when DSC is enabled

[how]
- Read eDP panel's DSC capabilities
- Apply DSC policy on eDP panel based on its DSC capabilities
- Enable DSC encoder's on the pipe
- Enable DSC on panel's side by setting DSC_ENABLE DPCD register
- Adding link optimization algorithm to reduce link rate or lane
count based

Subject: drm/amd/display: Fix eDP will flash when boot to OS

[WHY]
With eDP DSC enabled and set 4K 60Hz, there would be screen
corruption when booting to OS or enabling the driver.

[HOW]
Avoid powering down VDD when we cannot apply eDP fast boot.

Subject: drm/amd/display: fixed the DSC power off sequence during Driver PnP

[WHY]
After unloading driver, driver would not disable DSC function.
At next loading driver, driver would power all DSC engines off.
When driver powered the active DSC off, the screen would be gray
until reprograming DSC relatived register correcntly.

[HOW]
1. Remove DSC Power down code into init_pipes()
2. Depend on  the OTG mapping information and DSC status to skip
power off for the working DSC.

Subject: drm/amd/display: Fix OLED brightness control on eDP
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

[Why]
After commit ("drm/amdgpu/display: add support for multiple backlights")
number of eDPs is defined while registering backlight device.
However the panel's extended caps get updated once before register call.
That leads to regression with extended caps like oled brightness control.

[How]
Update connector ext caps after register_backlight_device

Fixes: 7fd13baeb7a3a4 ("drm/amdgpu/display: add support for multiple backlights")

Subject: drm/amdgpu: fix set scaling mode Full/Full aspect/Center not works on
 vga and dvi connectors

amdgpu_connector_vga_get_modes missed function amdgpu_get_native_mode
which assign amdgpu_encoder->native_mode with *preferred_mode result in
amdgpu_encoder->native_mode.clock always be 0. That will cause
amdgpu_connector_set_property returned early on:
if ((rmx_type != DRM_MODE_SCALE_NONE) &&
	(amdgpu_encoder->native_mode.clock == 0))
when we try to set scaling mode Full/Full aspect/Center.
Add the missing function to amdgpu_connector_vga_get_mode can fix this.
It also works on dvi connectors because
amdgpu_connector_dvi_helper_funcs.get_mode use the same method.

Subject: drm/amd/display: cleanup the code a bit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In function dc_sink_destruct, kfree will check pointer, no need
to check again.
This change is to cleanup the code a bit.

Subject: drm/amd/display: check top_pipe_to_program pointer

Clang static analysis reports this error

drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc.c:2870:7: warning:
Dereference of null pointer [clang-analyzer-core.NullDereference]
                if
(top_pipe_to_program->stream_res.tg->funcs->lock_doublebuffer_enable) {
                    ^

top_pipe_to_program being NULL is caught as an error
But then it is used to report the error.

So add a check before using it.

From ee2f17f4d02b14549272aa69da17bdcce2879d1b Mon Sep 17 00:00:00 2001
From: Amber Lin <Amber.Lin@amd.com>
Date: Thu, 18 Nov 2021 00:38:59 -0500
Subject: drm/amdkfd: Retrieve SDMA numbers from amdgpu

Instead of hard coding the number of sdma engines and the number of
sdma_xgmi engines in the device_info table, get the number of toal SDMA
instances from amdgpu. The first two engines are sdma engines and the
rest are sdma-xgmi engines unless the ASIC doesn't support XGMI.

v2: add kfd_ prefix to non static function names

Subject: drm/amdkfd: Remove unused entries in table

Remove unused entries in kfd_device_info table: num_xgmi_sdma_engines
and num_sdma_queues_per_engine. They are calculated in
kfd_get_num_sdma_engines and kfd_get_num_xgmi_sdma_engines instead.

amdgpu_amdkfd_gpuvm_free_memory_of_gpu drop dmabuf reference increased in
amdgpu_gem_prime_export.
amdgpu_bo_destroy drop dmabuf reference increased in
amdgpu_gem_prime_import.

So remove this extra dma_buf_put to avoid double free.

Subject: drm/amd/display: Fix DPIA outbox timeout after GPU reset

[Why]
The HW interrupt gets disabled after GPU reset so we don't receive
notifications for HPD or AUX from DMUB - leading to timeout and
black screen with (or without) DPIA links connected.

[How]
Re-enable the interrupt after GPU reset like we do for the other
DC interrupts.

Subject: drm/amd/display: Run full global validation in dc_commit_state

[Why]
Dynamic link encoder assignment expects that it can modify DC
current_state and the links associated with the incoming state when
performing full validation.

This does not align with our actual synchronization constraints
in DM's atomic_check.

[How]
Since link encoder assignment only happens as part of full validation
we can just use fast validation as part of atomic_check instead.

This satisfy's DC interface requirements and skips the DML calculations
needed for pipe programming - hopefully speeding up things a little bit
to offset the cost of double validation during stream modification.

We already do this as part of dc_commit_updates_for_stream()
with validate_bandwidth(), so extend this to dc_commit_state() as
well.

Subject: drm/amd/display: Set plane update flags for all planes in reset

[Why]
We're only setting the flags on stream[0]'s planes so this logic fails
if we have more than one stream in the state.

This can cause a page flip timeout with multiple displays in the
configuration.

[How]
Index into the stream_status array using the stream index - it's a 1:1
mapping.

Subject: drm/i915/pmu: Increase the live_engine_busy_stats sample period

Irrespective of the backend for request submissions, busyness for an
engine with an active context is calculated using:

busyness = total + (current_time - context_switch_in_time)

In execlists mode of operation, the context switch events are handled
by the CPU. Context switch in/out time and current_time are captured
in CPU time domain using ktime_get().

In GuC mode of submission, context switch events are handled by GuC and
the times in the above formula are captured in GT clock domain. This
information is shared with the CPU through shared memory. This results
in 2 caveats:

1) The time taken between start of a batch and the time that CPU is able
to see the context_switch_in_time in shared memory is dependent on GuC
and memory bandwidth constraints.

2) Determining current_time requires an MMIO read that can take anywhere
between a few us to a couple ms. A reference CPU time is captured soon
after reading the MMIO so that the caller can compare the cpu delta
between 2 busyness samples. The issue here is that the CPU delta and the
busyness delta can be skewed because of the time taken to read the
register.

These 2 factors affect the accuracy of the selftest -
live_engine_busy_stats. For (1) the selftest waits until busyness stats
are visible to the CPU. The effects of (2) are more prominent for the
current busyness sample period of 100 us. Increase the busyness sample
period from 100 us to 10 ms to overccome (2).

Subject: drm/hyperv: Fix device removal on Gen1 VMs

The Hyper-V DRM driver tries to free MMIO region on removing
the device regardless of VM type, while Gen1 VMs don't use MMIO
and hence causing the kernel to crash on a NULL pointer dereference.

Fix this by making deallocating MMIO only on Gen2 machines and implement
removal for Gen1

Subject: drm/amd/display: fixed an error related to 4:2:0/4:2:2 DSC

[Why]
OPTC_BYTES_PER_PIXEL calculation for 4:2:2 and 4:2:0 could have error.

[How]
Change to use following formula:
OPTC_DSC_BYTES_PER_PIXEL = ceiling((chunk size * 2^28) / slice width)

v2: squash in 64 bit divide fix (Alex)

From 6d63fcc2a334f7bd15e4e9b1db50a19335d2af4f Mon Sep 17 00:00:00 2001
From: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com>
Date: Tue, 9 Nov 2021 16:03:21 -0500
Subject: drm/amd/display: Reset link encoder assignments for GPU reset

[Why]
A warning appears in the log on GPU reset for
link_enc_cfg_link_encs_assign for the following condition:

ASSERT(state->res_ctx.link_enc_cfg_ctx.link_enc_assignments[i].valid == false);

This is not expected behavior and may result in link encoders being
incorrectly assigned.

[How]
The dc->current_state is backed up into dm->cached_dc_state before
we commit 0 streams.

DC will clear link encoder assignments on the real state but the
changes won't propagate over to the copy we made before the
0 streams commit.

DC expects that link encoder assignments are *not* valid
when committing a state, so as a workaround it needs to be cleared
before passing it back into DC.

Subject: drm/amd/display: Fix ODM combine issue with fast boot

[Why]
When systme power up and eDP lit up by VBIOS,
in the core_link_enable_stream(),
the function will early return due to apply
apply_edp_fast_boot_optimization,
resulting the DP_PIXEL_COMBINE cannot get set
in enc3_dp_set_odm_combine.

[How]
Check ODM PIPE to avoid early return.

Subject: drm/amdgpu: move kfd post_reset out of reset_sriov function

Fixes: 9f4f2c1a3524 ("drm/amd/amdgpu: fix the kfd pre_reset sequence in sriov")

For sriov XGMI  configuration, the host driver will handle the hive reset,
so in guest side, the reset_sriov only be called once on one device. This will
make kfd post_reset unblanced with kfd pre_reset since kfd pre_reset already
been moved out of reset_sriov function. Move kfd post_reset out of reset_sriov
function to make them balance .

Subject: drm/amdgpu: update the domain flags for dumb buffer creation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After switching to generic framebuffer framework, we rely on the
->dumb_create routine for frame buffer creation. However, the
different domain flags used are not optimal. Add the contiguous
flag to directly allocate the scanout BO as one linear buffer.

Fixes: 087451f372bf76 ("drm/amdgpu: use generic fb helpers instead of setting up AMD own's.")

Subject: drm/amd/pm: Print the error on command submission

Print the error on command submission immediately after submitting to
the SMU. This is rate-limited. It helps to immediately know there was an
error on command submission, rather than leave it up to clients to report
the error, as sometimes they do not.

Subject: drm/amdkfd: process exit and retry fault race

kfd_process_wq_release drain retry fault to ensure no retry fault comes
after removing kfd process from the hash table, otherwise svm page fault
handler will fail to recover the fault and dump GPU vm fault log.

Refactor deferred list work to get_task_mm and take mmap write lock
to handle all ranges, and avoid mm is gone while inserting mmu notifier.

unmap range always increase atomic svms->drain_pagefaults to simplify
both parent range and child range unmap, page fault handle ignores the
retry fault if svms->drain_pagefaults is set to speed up interrupt
handling. svm_range_drain_retry_fault restart draining if another
range unmap from cpu.

Subject: drm/amdgpu: enable Navi retry fault wptr overflow

If xnack is on, VM retry fault interrupt send to IH ring1, and ring1
will be full quickly. IH cannot receive other interrupts, this causes
deadlock if migrating buffer using sdma and waiting for sdma done
while handling retry fault.

Remove VMC from IH storm client, enable ring1 write pointer
overflow, then IH will drop retry fault interrupts and be able to receive
other interrupts while driver is handling retry fault.

IH ring1 write pointer doesn't writeback to memory by IH, and ring1
write pointer recorded by self-irq is not updated, so always read
the latest ring1 write pointer from register.

Subject: drm/amd/display: update bios scratch when setting backlight

Update the bios scratch register when updating the backlight
level.  Some platforms apparently read this scratch register
and do additional operations in their hotkey handlers.

Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1518

amdgpu_amdkfd_gpuvm_free_memory_of_gpu drop dmabuf reference increased in
amdgpu_gem_prime_export.
amdgpu_bo_destroy drop dmabuf reference increased in
amdgpu_gem_prime_import.

So remove this extra dma_buf_put to avoid double free.

Subject: drm/amd/display: Fix DPIA outbox timeout after GPU reset

[Why]
The HW interrupt gets disabled after GPU reset so we don't receive
notifications for HPD or AUX from DMUB - leading to timeout and
black screen with (or without) DPIA links connected.

[How]
Re-enable the interrupt after GPU reset like we do for the other
DC interrupts.

Subject: drm/amd/display: Set plane update flags for all planes in reset

[Why]
We're only setting the flags on stream[0]'s planes so this logic fails
if we have more than one stream in the state.

This can cause a page flip timeout with multiple displays in the
configuration.

[How]
Index into the stream_status array using the stream index - it's a 1:1
mapping.

Subject: drm/amd/display: Reset link encoder assignments for GPU reset

[Why]
A warning appears in the log on GPU reset for
link_enc_cfg_link_encs_assign for the following condition:

ASSERT(state->res_ctx.link_enc_cfg_ctx.link_enc_assignments[i].valid == false);

This is not expected behavior and may result in link encoders being
incorrectly assigned.

[How]
The dc->current_state is backed up into dm->cached_dc_state before
we commit 0 streams.

DC will clear link encoder assignments on the real state but the
changes won't propagate over to the copy we made before the
0 streams commit.

DC expects that link encoder assignments are *not* valid
when committing a state, so as a workaround it needs to be cleared
before passing it back into DC.

Subject: drm/amdgpu: move kfd post_reset out of reset_sriov function

Fixes: 9f4f2c1a3524 ("drm/amd/amdgpu: fix the kfd pre_reset sequence in sriov")

For sriov XGMI  configuration, the host driver will handle the hive reset,
so in guest side, the reset_sriov only be called once on one device. This will
make kfd post_reset unblanced with kfd pre_reset since kfd pre_reset already
been moved out of reset_sriov function. Move kfd post_reset out of reset_sriov
function to make them balance .

Subject: drm/amdkfd: simplify drain retry fault

unmap range always increase atomic svms->drain_pagefaults to simplify
both parent range and child range unmap, page fault handle ignores the
retry fault if svms->drain_pagefaults is set to speed up interrupt
handling. svm_range_drain_retry_fault restart draining if another
range unmap from cpu.

Subject: drm/amdgpu: enable Navi retry fault wptr overflow

If xnack is on, VM retry fault interrupt send to IH ring1, and ring1
will be full quickly. IH cannot receive other interrupts, this causes
deadlock if migrating buffer using sdma and waiting for sdma done
while handling retry fault.

Remove VMC from IH storm client, enable ring1 write pointer
overflow, then IH will drop retry fault interrupts and be able to receive
other interrupts while driver is handling retry fault.

IH ring1 write pointer doesn't writeback to memory by IH, and ring1
write pointer recorded by self-irq is not updated, so always read
the latest ring1 write pointer from register.

Subject: drm/amd/display: update bios scratch when setting backlight

Update the bios scratch register when updating the backlight
level.  Some platforms apparently read this scratch register
and do additional operations in their hotkey handlers.

Subject: drm/i915: Add support for moving fence waiting
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For now, we will only allow async migration when TTM is used,
so the paths we care about are related to TTM.

The mmap path is handled by having the fence in ttm_bo->moving,
when pinning, the binding only becomes available after the moving
fence is signaled, and pinning a cpu map will only work after
the moving fence signals.

This should close all holes where userspace can read a buffer
before it's fully migrated.

v2:
- Fix a couple of SPARSE warnings
v3:
- Fix a NULL pointer dereference
v4:
- Ditch the moving fence waiting for i915_vma_pin_iomap() and
  replace with a verification that the vma is already bound.
  (Matthew Auld)
- Squash with a previous patch introducing moving fence waiting and
  accessing interfaces (Matthew Auld)
- Rename to indicated that we also add support for sync waiting.
v5:
- Fix check for NULL and unreferencing i915_vma_verify_bind_complete()
  (Matthew Auld)
- Fix compilation failure if !CONFIG_DRM_I915_DEBUG_GEM
- Fix include ordering. (Matthew Auld)
v7:
- Fix yet another compilation failure with clang if
  !CONFIG_DRM_I915_DEBUG_GEM

Move the i915_gem_obj_copy_ttm() function to i915_gem_ttm_move.h.
This will help keep a number of functions static when introducing
async moves.

From 8b1f7f92e57d7eff7a3503763dd2c8e0357c36ff Mon Sep 17 00:00:00 2001
From: Thomas Hellström <thomas.hellstrom@linux.intel.com>

Subject: drm/i915/ttm: Drop region reference counting
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There is an interesting refcounting loop:
struct intel_memory_region has a struct ttm_resource_manager,
ttm_resource_manager->move may hold a reference to i915_request,
i915_request may hold a reference to intel_context,
intel_context may hold a reference to drm_i915_gem_object,
drm_i915_gem_object may hold a reference to intel_memory_region.

Break this loop by dropping region reference counting.

In addition, Have regions with a manager moving fence make sure
that all region objects are released before freeing the region.

v6:
- Fix a code comment.

Subject: drm/i915/ttm: Correctly handle waiting for gpu when shrinking
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With async migration, the shrinker may end up wanting to release the
pages of an object while the migration blit is still running, since
the GT migration code doesn't set up VMAs and the shrinker is thus
oblivious to the fact that the GPU is still using the pages.

Add waiting for gpu in the shrinker_release_pages() op and an
argument to that function indicating whether the shrinker expects it
to not wait for gpu. In the latter case the shrinker_release_pages()
op will return -EBUSY if the object is not idle.

Subject: drm/i915/ttm: Implement asynchronous TTM moves
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Don't wait sync while migrating, but rather make the GPU blit await the
dependencies and add a moving fence to the object.

This also enables asynchronous VRAM management in that on eviction,
rather than waiting for the moving fence to expire before freeing VRAM,
it is freed immediately and the fence is stored with the VRAM manager and
handed out to newly allocated objects to await before clears and swapins,
or for kernel objects before setting up gpu vmas or mapping.

To collect dependencies before migrating, add a set of utilities that
coalesce these to a single dma_fence.

What is still missing for fully asynchronous operation is asynchronous vma
unbinding, which is still to be implemented.

This commit substantially reduces execution time in the gem_lmem_swapping
test.

v2:
- Make a couple of functions static.
v4:
- Fix some style issues (Matthew Auld)
- Audit and add more checks for ghost objects (Matthew Auld)
- Add more documentation for the i915_deps utility (Mattew Auld)
- Simplify the i915_deps_sync() function
v6:
- Re-check for fence signaled before returning -EBUSY (Matthew Auld)
- Use dma_resv_iter_is_exclusive() (Matthew Auld)
- Await all dma-resv fences before a migration blit (Matthew Auld)

Subject: drm/i915: Remove dma_resv_prune
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The signaled bit is already used for quick testing if a fence is signaled.
On top of that, it's a terrible abuse of dma-fence api, and in the common
case where the object is already locked by the caller, the trylock will fail.

If it were useful, the core dma-api would have exposed the same functionality.

The fact that i915 has a dma_resv_utils.c file should be a warning that the
functionality either belongs in core, or is not very useful at all.
In this case the latter.

Subject: drm/i915: Avoid allocating a page array for the gpu coredump
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The gpu coredump typically takes place in a dma_fence signalling
critical path, and hence can't use GFP_KERNEL allocations, as that
means we might hit deadlocks under memory pressure. However
changing to __GFP_KSWAPD_RECLAIM which will be done in an upcoming
patch will instead mean a lower chance of the allocation succeeding.
In particular large contigous allocations like the coredump page
vector.
Remove the page vector in favor of a linked list of single pages.
Use the page lru list head as the list link, as the page owner is
allowed to do that.

Subject: drm/i915: Use __GFP_KSWAPD_RECLAIM in the capture code
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The capture code is typically run entirely in the fence signalling
critical path. We're about to add lockdep annotation in an upcoming patch
which reveals a lockdep splat similar to the below one.

Fix the associated potential deadlocks using __GFP_KSWAPD_RECLAIM
(which is the same as GFP_WAIT, but open-coded for clarity) rather than
GFP_KERNEL for memory allocation in the capture path. This has the
potential drawback that capture might fail in situations with memory
pressure.

Subject: drm/i915/gemfs: don't mark huge_opt as static

vfs_kernel_mount() modifies the passed in mount options, leaving us with
"huge", instead of "huge=within_size". Normally this shouldn't matter
with the usual module load/unload flow, however with the core_hotunplug
IGT we are hitting the following, when re-probing the memory regions:

i915 0000:00:02.0: [drm] Transparent Hugepage mode 'huge'
tmpfs: Bad value for 'huge'
[drm] Unable to create a private tmpfs mount, hugepage support will be disabled(-22).

Subject: drm: msm: fix building without CONFIG_COMMON_CLK

When CONFIG_COMMON_CLOCK is disabled, the 8996 specific
phy code is left out, which results in a link failure:

ld: drivers/gpu/drm/msm/hdmi/hdmi_phy.o:(.rodata+0x3f0): undefined reference to `msm_hdmi_phy_8996_cfg'

This was only exposed after it became possible to build
test the driver without the clock interfaces.

Make COMMON_CLK a hard dependency for compile testing,
and simplify it a little based on that.

Fixes: b3ed524f84f5 ("drm/msm: allow compile_test on !ARM")

Subject: drm/msm/dpu: move dpu_hw_pipe_cfg out of struct dpu_plane

struct dpu_hw_pipe_cfg represents an interim state during atomic
update/color fill, so move it out of struct dpu_plane.

Subject: drm/msm/edp: drop old eDP support

MSM DRM driver has support for eDP block present on MSM 8x74/8x84 SoC
families. However since addition back in 2015 this driver received only
generic fixes. No actual devices with these SoCs supported upstream (or
by the community) seem to support eDP panels. Judging from downstream

Subject: drm/msm/dsi: stop setting clock parents manually

There is no reason to set clock parents manually, use device tree to
assign DSI/display clock parents to DSI PHY clocks. Dropping this manual
setup allows us to drop repeating code and to move registration of hw
clock providers to generic place.

Subject: drm/msm/dp: Add DP controllers for sc7280

The eDP controller on SC7280 is similar to the eDP/DP controllers
supported by the current driver implementation.

SC7280 supports one EDP and one DP controller which can operate
concurrently.

This change adds the support for eDP and DP controller on sc7280.

Signed-off-by: Sankeerth Billakanti <quic_sbillaka@quicinc.com>

changes in v3:
    - Split into patches according to function (Dmitry Baryshkov)
    - Use DP_CONTROLLER_1 for eDP controller intf (Dmitry Baryshkov)
    - Use DP_CONTROLLER_0 for sc7280-dp (Dmitry Baryshkov)
    - Add macro in drm_helper.h for checking ssc capability (Stephen Boyd)
    - Use existing macro to check assr capability (Stephen Boyd)
    - Add comment for HPD_INIT_SETUP delay (Stephen Boyd)

changes in v2:
    - Don't initialize variables to 0 (Stephen Boyd)
    - Use const for read-only dpcd (Stephen Boyd)
    - Remove zero pixel clock check (Stephen Boyd)
    - Sort compatible strings alphabetically (Stephen Boyd)
    - Use pwm_bl.c for backlight instead of gpio (Stephen Boyd)
    - Change return type for functions returning always 0 (Matthias Kaehlcke)

The sc7280 eDP sink that supports downspread will fail link training
if source does not enable SSC / downspread. This change will set the
downspread bit in the DP sink if supported and indicate SSC support
to the DP PHY driver.

The eDP sink on sc7280 supports ASSR and dp driver will
enable ASSR in the source hardware. The driver needs to
enable the ASSR field in the DPCD configuration register
to avoid screen corruption. This change will enable ASSR
if supported in the sink device.

Subject: drm/msm/mdp5: drop vdd regulator

The "vdd" regulator was used by the mdp5 driver only on downstream
kernels, where the GDSC is represented as a regulator. On all current
kernels the MDSS_GDSC is implemented as the power domain, removing the
need for this regulator. Remove it from the mdp5 driver.

Subject: drm/msm: Drop priv->lastctx

cur_ctx_seqno already does the same thing, but handles the edge cases
where a refcnt'd context can live after lastclose.  So let's not have
two ways to do the same thing.

Subject: drm/msm: Remove struct_mutex usage

The remaining struct_mutex usage is just to serialize various gpu
related things (submit/retire/recover/fault/etc), so replace
struct_mutex with gpu->lock.

Subject: drm/msm: Add debugfs to disable hw err handling

Add a debugfs interface to ignore hw error irqs, in order to force
fallback to sw hangcheck mechanism.  Because the hw error detection is
pretty good on newer gens, we need this for igt tests to test the sw
hang detection.

Subject: drm/msm: Increase gpu boost interval

Currently, we boost gpu freq after 25ms of inactivity. This regresses
some of the 30 fps usecases where the workload on gpu (at 33ms internval)
is very small which it can finish at the lowest OPP before the deadline.
Lets increase this inactivity threshold to 50ms (same as the current
devfreq interval) to fix this.

Subject: drm/msm/gpu: Respect PM QoS constraints

Re-work the boost and idle clamping to use PM QoS requests instead, so
they get aggreggated with other requests (such as cooling device).

This does have the minor side-effect that devfreq sysfs min_freq/
max_freq files now reflect the boost and idle clamping, as they show
(despite what they are documented to show) the aggregated min/max freq.
Fixing that in devfreq does not look straightforward after considering
that OPPs can be dynamically added/removed.  However writes to the
sysfs files still behave as expected.

v2: Use 64b math to avoid potential 32b overflow

Subject: drm/virtgpu api: define a dummy fence signaled event

The current virtgpu implementation of poll(..) drops events
when VIRTGPU_CONTEXT_PARAM_POLL_RINGS_MASK is enabled (otherwise
it's like a normal DRM driver).

This is because paravirtualized userspaces receives responses in a
buffer of type BLOB_MEM_GUEST, not by read(..).

To be in line with other DRM drivers and avoid specialized behavior,
it is possible to define a dummy event for virtgpu.  Paravirtualized
userspace will now have to call read(..) on the DRM fd to receive the
dummy event.

Subject: drm/vc4: kms: Wait for the commit before increasing our clock rate

Several DRM/KMS atomic commits can run in parallel if they affect
different CRTC. These commits share the global HVS state, so we have
some code to make sure we run commits in sequence. This synchronization
code is one of the first thing that runs in vc4_atomic_commit_tail().

Another constraints we have is that we need to make sure the HVS clock
gets a boost during the commit. That code relies on clk_set_min_rate and
will remove the old minimum and set a new one. We also need another,
temporary, minimum for the duration of the commit.

The algorithm is thus to set a temporary minimum, drop the previous
one, do the commit, and finally set the minimum for the current mode.

However, the part that sets the temporary minimum and drops the older
one runs before the commit synchronization code.

Thus, under the proper conditions, we can end up mixing up the minimums
and ending up with the wrong one for our current step.

To avoid it, let's move the clock setup in the protected section.

Commit 9ec03d7f1ed3 ("drm/vc4: kms: Wait on previous FIFO users before a

the current CRTC commit so that we can properly synchronize commits.

However, the refcounting was off and we thus ended up leaking the
drm_crtc_commit structure every commit. Add a drm_crtc_commit_put to
prevent the leakage.

Subject: drm/vc4: kms: Clear the HVS FIFO commit pointer once done

Commit 9ec03d7f1ed3 ("drm/vc4: kms: Wait on previous FIFO users before a
commit") introduced a wait on the previous commit done on a given HVS
FIFO.

However, we never cleared that pointer once done. Since
drm_crtc_commit_put can free the drm_crtc_commit structure directly if
we were the last user, this means that it can lead to a use-after free
if we were to duplicate the state, and that stale pointer would even be
copied to the new state.

Set the pointer to NULL once we're done with the wait so that we don't
carry over a pointer to a free'd structure.

Subject: drm/vc4: kms: Don't duplicate pending commit

Our HVS global state, when duplicated, will also copy the pointer to the
drm_crtc_commit (and increase the reference count) for each FIFO if the
pointer is not NULL.

However, our atomic_setup function will overwrite that pointer without
putting the reference back leading to a memory leak.

Since the commit is only relevant during the atomic commit process, it
doesn't make sense to duplicate the reference to the commit anyway.
Let's remove it.

Subject: drm/vc4: kms: Fix previous HVS commit wait

Our current code is supposed to serialise the commits by waiting for all
the drm_crtc_commits associated to the previous HVS state.

However, assuming we have two CRTCs running and being configured and we
configure each one alternately, we end up in a situation where we're
not waiting at all.

Indeed, starting with a state (state 0) where both CRTCs are running,
and doing a commit (state 1) on the first CRTC (CRTC 0), we'll associate
its commit to its assigned FIFO in vc4_hvs_state.

If we get a new commit (state 2), this time affecting the second CRTC
(CRTC 1), the DRM core will allow both commits to execute in parallel
(assuming they don't have any share resources).

Our code in vc4_atomic_commit_tail is supposed to make sure we only get
one commit at a time and serialised by order of submission. It does so
by using for_each_old_crtc_in_state, making sure that the CRTC has a
FIFO assigned, is used, and has a commit pending. If it does, then we'll
wait for the commit before going forward.

During the transition from state 0 to state 1, as our old CRTC state we
get the CRTC 0 state 0, its commit, we wait for it, everything works fine.

During the transition from state 1 to state 2 though, the use of
for_each_old_crtc_in_state is wrong. Indeed, while the code assumes it's
returning the state of the CRTC in the old state (so CRTC 0 state 1), it
actually returns the old state of the CRTC affected by the current
commit, so CRTC 0 state 0 since it wasn't part of state 1.

Due to this, if we alternate between the configuration of CRTC 0 and
CRTC 1, we never actually wait for anything since we should be waiting
on the other every time, but it never is affected by the previous
commit.

Change the logic to, at every commit, look at every FIFO in the previous
HVS state, and if it's in use and has a commit associated to it, wait
for that commit.

Content-Transfer-Encoding: 8bit

This simply adds proper support for panel backlights that can be controlled
via VESA's backlight control protocol, but which also require that we
enable and disable the backlight via PWM instead of via the DPCD interface.
We also enable this by default, in order to fix some people's backlights
that were broken by not having this enabled.

For reference, backlights that require this and use VESA's backlight
interface tend to be laptops with hybrid GPUs, but this very well may
change in the future.

It appears to be a GMU fw build option whether it does anything with
debug and log buffers, but if they are all zeros it won't add anything
to the devcore size.

If you don't realize is_a650_family() also encompasses a660 family,
you'd think that the debug buffer is double allocated.  Add a comment
to make this more clear.

Subject: drm/msm/dp: Drop now unused hpd_high member

Since '8ede2ecc3e5e ("drm/msm/dp: Add DP compliance tests on Snapdragon
Chipsets")' the hpd_high member of struct dp_usbpd has been write-only.

Let's clean up the code a little bit by removing the writes as well.

Subject: drm/vmwgfx: Copy DRM hash-table code into driver

Besides some legacy code, vmwgfx is the only user of DRM's hash-
table implementation. Copy the code into the driver, so that the
core code can be retired.

No functional changes. However, the real solution for vmwgfx is to
use Linux' generic hash-table functions.

v2:
	* add TODO item for updating vmwgfx (Sam)

Subject: drm: Declare hashtable as legacy

The DRM hashtable code is only used by internal functions for legacy
UMS drivers. Move the implementation behind CONFIG_DRM_LEGACY and the
declarations into legacy header files. Unexport the symbols.

From e580ea25c08d9e89593bcf80640e29108f0542cb Mon Sep 17 00:00:00 2001
From: Thomas Zimmermann <tzimmermann@suse.de>
Date: Mon, 15 Nov 2021 13:01:48 +0100
Subject: drm/cma-helper: Pass GEM CMA object in public interfaces

Change all GEM CMA object functions that receive a GEM object
of type struct drm_gem_object to expect an object of type
struct drm_gem_cma_object instead.

This change reduces the number of upcasts from struct drm_gem_object
by moving them into callers. The C compiler can now verify that the
GEM CMA functions are called with the correct type.

For consistency, the patch also renames drm_gem_cma_free_object to
drm_gem_cma_free. It further updates documentation for a number of
functions.

Subject: drm/mipi-dbi: Remove dependency on GEM CMA helper library

The MIPI DBI helpers access struct drm_gem_cma_object.vaddr in a
few places. Replace all instances with the correct generic GEM
functions. Use drm_gem_fb_vmap() for mapping a framebuffer's GEM
objects and drm_gem_fb_vunmap() for unmapping them. This removes
the dependency on CMA helpers within MIPI DBI.

From 09717af7d13d63df141ae6e71686289989d17efd Mon Sep 17 00:00:00 2001
From: Thomas Zimmermann <tzimmermann@suse.de>

Subject: drm: Remove CONFIG_DRM_KMS_CMA_HELPER option

Link drm_fb_cma_helper.o into drm_cma_helper.ko if CONFIG_DRM_KMS_HELPER
has been set. Remove CONFIG_DRM_KMS_CMA_HELPER config option. Selecting
KMS helpers and CMA will now automatically enable CMA KMS helpers.

Some drivers' Kconfig files did not correctly select KMS or CMA helpers.
Fix this as part of the change.

Subject: lontium-lt9611: check a different register bit for HDMI sensing

It has been observed that with certain monitors such as the HP Z27n,
the register 0x825e reads a value of 0x79 when the HDMI cable is
connected and 0x78 when it is disconnected, i.e. bit 0 appears
to correspond to the HDMI connection status and bit 2 is never
set. Therefore, change the driver to check bit 0 instead of bit 2.

Subject: drm/qxl: use iterator instead of dma_resv_shared_list
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I'm not sure why it is useful to know the number of fences
in the reservation object, but we try to avoid exposing the
dma_resv_shared_list() function.

So use the iterator instead. If more information is desired
we could use dma_resv_describe() as well.

Subject: drm/i915/pmu: Fix synchronization of PMU callback with reset

Since the PMU callback runs in irq context, it synchronizes with gt
reset using the reset count. We could run into a case where the PMU
callback could read the reset count before it is updated. This has a
potential of corrupting the busyness stats.

In addition to the reset count, check if the reset bit is set before
capturing busyness.

In addition save the previous stats only if you intend to update them.

v2:
- The 2 reset counts captured in the PMU callback can end up being the
  same if they were captured right after the count is incremented in the
  reset flow. This can lead to a bad busyness state. Ensure that reset
  is not in progress when the initial reset count is captured.

Subject: drm/i915: Drop stealing of bits from i915_sw_fence function pointer

Rather than stealing bits from i915_sw_fence function pointer use
separate fields for function pointer and flags. If using two different
fields, the 4 byte alignment for the i915_sw_fence function pointer can
also be dropped.

v2:
 (CI)
  - Set new function field rather than flags in __i915_sw_fence_init
v3:
 (Tvrtko)
  - Remove BUG_ON(!fence->flags) in reinit as that will now blow up
  - Only define fence->flags if CONFIG_DRM_I915_SW_FENCE_CHECK_DAG is
    defined
v4:
  - Rebase, resend for CI

From cca084692394ad2733995241866fbb4b1b8668bc Mon Sep 17 00:00:00 2001
From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Subject: drm/i915: Use per device iommu check

With both integrated and discrete Intel GPUs in a system, the current
global check of intel_iommu_gfx_mapped, as done from intel_vtd_active()
may not be completely accurate.

In this patch we add i915 parameter to intel_vtd_active() in order to
prepare it for multiple GPUs and we also change the check away from Intel
specific intel_iommu_gfx_mapped (global exported by the Intel IOMMU
driver) to probing the presence of IOMMU on a specific device using
device_iommu_mapped().

This will return true both for IOMMU pass-through and address translation
modes which matches the current behaviour. If in the future we wanted to
distinguish between these two modes we could either use
iommu_get_domain_for_dev() and check for __IOMMU_DOMAIN_PAGING bit
indicating address translation, or ask for a new API to be exported from
the IOMMU core code.

v2:
  * Check for dmar translation specifically, not just iommu domain. (Baolu)

v3:
 * Go back to plain "any domain" check for now, rewrite commit message.

v4:
 * Use device_iommu_mapped. (Robin, Baolu)

Subject: drm/i915/gem: Fix a NULL pointer dereference in igt_request_rewind()

In igt_request_rewind(), mock_context(i915, "A") is assigned to ctx[0]
and used in i915_gem_context_get_engine(). There is a dereference
of ctx[0] in i915_gem_context_get_engine(), which could lead to a NULL
pointer dereference on failure of mock_context(i915, "A") .

So as mock_context(i915, "B").

Although this bug is not serious for it belongs to testing code, it is
better to be fixed to avoid unexpected failure in testing.

Fix this bugs by adding checks about ctx[0] and ctx[1].

This bug was found by a static analyzer. The analysis employs
differential checking to identify inconsistent security operations
(e.g., checks or kfrees) between two code paths and confirms that the
inconsistent operations are not recovered in the current function or
the callers, so they constitute bugs.

Note that, as a bug found by static analysis, it can be a false
positive or hard to trigger. Multiple researchers have cross-reviewed
the bug.

Builds with CONFIG_DRM_I915_SELFTEST=y show no new warnings,
and our static analyzer no longer warns about this code.

Subject: drm/etnaviv: fix dma configuration of the virtual device

The DMA configuration of the virtual device is inherited from the first
actual etnaviv device. Unfortunately, this doesn't work with an IOMMU:

[    5.191008] Failed to set up IOMMU for device (null); retaining platform DMA ops

This is because there is no associated iommu_group with the device. The
group is set in iommu_group_add_device() which is eventually called by
device_add() via the platform bus:
  device_add()
    blocking_notifier_call_chain()
      iommu_bus_notifier()
        iommu_probe_device()
          __iommu_probe_device()
            iommu_group_get_for_dev()
              iommu_group_add_device()

Move of_dma_configure() into the probe function, which is called after
device_add(). Normally, the platform code will already call it itself
if .of_node is set. Unfortunately, this isn't the case here.

Subject: drm/etnaviv: use a 32 bit mask as coherent DMA mask

The STLB and the first command buffer (which is used to set up the TLBs)
has a 32 bit size restriction in hardware. There seems to be no way to
specify addresses larger than 32 bit. Keep it simple and restict the
addresses to the lower 4 GiB range for all coherent DMA memory
allocations.

Please note, that platform_device_alloc() will initialize dev->dma_mask
to point to pdev->platform_dma_mask, thus dma_set_mask() will work as
expected.

While at it, move the dma_mask setup code to the of_dma_configure() to
keep all the DMA setup code next to each other.

Subject: drm/i915/dp: Perform 30ms delay after source OUI write
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While working on supporting the Intel HDR backlight interface, I noticed
that there's a couple of laptops that will very rarely manage to boot up
without detecting Intel HDR backlight support - even though it's supported
on the system. One example of such a laptop is the Lenovo P17 1st
generation.

Following some investigation Ville Syrjälä did through the docs they have
available to them, they discovered that there's actually supposed to be a
30ms wait after writing the source OUI before we begin setting up the rest
of the backlight interface.

This seems to be correct, as adding this 30ms delay seems to have
completely fixed the probing issues I was previously seeing. So - let's
start performing a 30ms wait after writing the OUI, which we do in a manner
similar to how we keep track of PPS delays (e.g. record the timestamp of
the OUI write, and then wait for however many ms are left since that
timestamp right before we interact with the backlight) in order to avoid
waiting any longer then we need to. As well, this also avoids us performing
this delay on systems where we don't end up using the HDR backlight
interface.

V3:
* Move last_oui_write into intel_dp
V2:
* Move panel delays into intel_pps

From ff20afc4cee7b65f752b1da6d5da4c0bea1431b9 Mon Sep 17 00:00:00 2001
From: Thomas Hellström <thomas.hellstrom@linux.intel.com>
Date: Mon, 29 Nov 2021 21:22:45 +0100
Subject: drm/i915: Update error capture code to avoid using the current vma
 state
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With asynchronous migrations, the vma state may be several migrations
ahead of the state that matches the request we're capturing.
Address that by introducing an i915_vma_snapshot structure that
can be used to snapshot relevant state at request submission.
In order to make sure we access the correct memory, the snapshots take
references on relevant sg-tables and memory regions.

Also move the capture list allocation out of the fence signaling
critical path and use the CONFIG_DRM_I915_CAPTURE_ERROR define to
avoid compiling in members and functions used for error capture
when they're not used.

Finally, Introduce lockdep annotation.

v4:
- Break out the capture allocation mode change to a separate patch.
v5:
- Fix compilation error in the !CONFIG_DRM_I915_CAPTURE_ERROR case
  (kernel test robot)
v6:
- Use #if IS_ENABLED() instead of #ifdef to match driver style.
- Move yet another change of allocation mode to the separate patch.
- Commit message rework due to patch reordering.
v7:
- Adjust for removal of region refcounting.

From 826c387d015247df396a91eadbaca94f0394853c Mon Sep 17 00:00:00 2001
From: Zack Rusin <zackr@vmware.com>

Subject: drm/vmwgfx: Remove the deprecated lower mem limit

TTM during the transition to the new page allocator lost the ability
to constrain the allocations via the lower_mem_limit. The code has
been unused since the change:
256dd44bd897 ("drm/ttm: nuke old page allocator")
and there's no reason to keep it.

Fixes: 256dd44bd897 ("drm/ttm: nuke old page allocator")
Signed-off-by: Zack Rusin <zackr@vmware.com>

Subject: drm/vmwgfx: Release ttm memory if probe fails

The ttm mem global state was leaking if the vmwgfx driver load failed.

In case of a driver load failure we have to make sure we also release
the ttm mem global state.

Subject: drm/vmwgfx: Fail to initialize on broken configs

Some of our hosts have a bug where rescaning a pci bus results in stale
fifo memory being mapped on the host. This makes any fifo communication
impossible resulting in various kernel crashes.

Instead of unexpectedly crashing, predictably fail to load the driver
which will preserve the system.

Subject: drm/vmwgfx: Introduce a new placement for MOB page tables
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For larger (bigger than a page) and noncontiguous mobs we have
to create page tables that allow the host to find the memory.
Those page tables just used regular system memory. Unfortunately
in TTM those BO's are not allowed to be busy thus can't be
fenced and we have to fence those bo's  because we don't want
to destroy the page tables while the host is still executing
the command buffers which might be accessing them.

To solve it we introduce a new placement VMW_PL_SYSTEM which
is very similar to TTM_PL_SYSTEM except that it allows
fencing. This fixes kernel oops'es during unloading of the driver
(and pci hot remove/add) which were caused by busy BO's in
TTM_PL_SYSTEM being present in the delayed deletion list in
TTM (TTM_PL_SYSTEM manager is destroyed before the delayed
deletions are executed)

Subject: drm/vmwgfx: Switch the internal BO's to ttm_bo_type_kernel

There's never a need to access our internal kernel bo's from
user-space. Those objects are used exclusively for internal
support to guest backed surfaces (in otable setup and mob
page tables) and there's no need to have them be of device
type, i.e. mmappable from user-space.

This workarounds are causing hangs, because I missed the fact that it
needs to be enabled for all cases and disabled when doing a resolve
pass.

So KMD only needs to whitelist it and UMD will be the one setting it
on per case.

This reverts commit 28ec02c9cbebf3feeaf21a59df9dfbc02bda3362.

Subject: drm/amdgpu/display: Only set vblank_disable_immediate when PSR is not
 enabled

[Why]
PSR currently relies on the kernel's delayed vblank on/off mechanism
as an implicit bufferring mechanism to prevent excessive entry/exit.

Without this delay the user experience is impacted since it can take
a few frames to enter/exit.

[How]
Only allow vblank disable immediate for DC when psr is not supported.

Leave a TODO indicating that this support should be extended in the
future to delay independent of the vblank interrupt.

Fixes: 92020e81ddbeac ("drm/amdgpu/display: set vblank_disable_immediate for DC")

The 'doorbell_bitmap' bitmap has just been allocated. So we can use the
non-atomic '__set_bit()' function to save a few cycles as no concurrent
access can happen.

v2:
    still need call ras_disable_all_featrures to handle
    ras initilization failure case.

Function amdgpu_device_fini_hw is called before amdgpu_device_fini_sw,
so ras ta will unload before send ras disable command, ras dsiable operation
must before hw fini.

Subject: drm/amdgpu: handle IH ring1 overflow
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

IH ring1 is used to process GPU retry fault, overflow is enabled to
drain retry fault because we want receive other interrupts while
handling retry fault to recover range. There is no overflow flag set
when wptr pass rptr. Use timestamp of rptr and wptr to handle overflow
and drain retry fault.

If fault timestamp goes backward, the fault is filtered and should not
be processed. Drain fault is finished if processed_timestamp is equal to
or larger than checkpoint timestamp.

Add amdgpu_ih_functions interface decode_iv_ts for different chips to
get timestamp from IV entry with different iv size and timestamp offset.
amdgpu_ih_decode_iv_ts_helper is used for vega10, vega20, navi10.

Subject: amdgpu/pm: Create shared array of power profile name strings

 == Description ==
 All the power profile modes use the same strings (or a subset of)
 Creating a public array of the strings will allow sharing rather than
 duplicating for each chip
 First patch only implements change for navi10, followup with other chips

 == Changes ==
 Create a declaration of the public array in kgd_pp_interface.h
 Define the public array in amdgpu_pm.c
 Modify the implementaiton of navi10_get_power_profile_mode to use new array

 == Test ==
 LOGFILE=pp_profile_strings.test.log

 AMDGPU_HWMON=`ls -la /sys/class/hwmon | grep $AMDGPU_PCI_ADDR | awk '{print $9}'`
 HWMON_DIR=/sys/class/hwmon/${AMDGPU_HWMON}

 FILES="pp_power_profile_mode "

 for f in $FILES

Subject: drm/amd/display: Add DP-HDMI FRL PCON Support in DC

Change since v1: add brief description
1. Add hdmi frl pcon support to existing asic family.
2. Determine pcon frl capability based on pcon dpcd.
3. pcon frl is taken into consideration into mode validation.

v2: squash in warning fix (Alex)

Subject: drm/amd/display: Allow DSC on supported MST branch devices

[Why]
When trying to lightup two 4k60 non-DSC displays behind a branch device
that supports DSC we can't lightup both at once due to bandwidth
limitations - each requires 48 VCPI slots but we only have 63.

[How]
The workaround already exists in the code but is guarded by a CONFIG
that cannot be set by the user and shouldn't need to be.

Check for specific branch device IDs to device whether to enable
the workaround for multiple display scenarios.

Subject: drm/amd/display: Fix for otg synchronization logic

[Why]
During otg sync trigger, plane states are used to decide whether the otg
is already synchronized or not. There are scenarions when otgs are
disabled without plane state getting disabled and in such case the otg is
excluded from synchronization.

[How]
Introduced pipe_idx_syncd in pipe_ctx that tracks each otgs master pipe.
When a otg is disabled/enabled, pipe_idx_syncd is reset to itself.
On sync trigger, pipe_idx_syncd is checked to decide whether a otg is
already synchronized and the otg is further included or excluded from
synchronization.

Subject: drm/amd/display: Fix for the no Audio bug with Tiled Displays

[WHY]
It seems like after a series of plug/unplugs we end up in a situation
where tiled display doesnt support Audio.

[HOW]
The issue seems to be related to when we check streams changed after an
HPD, we should be checking the audio_struct as well to see if any of its
values changed.

From: Jimmy Kizito <Jimmy.Kizito@amd.com>
Date: Sun, 14 Nov 2021 21:48:02 -0500
Subject: drm/amd/display: Add work around for tunneled MST.

[Why]
Certain USB4 docks do not seem to be able to handle disabling
DSC once it has been enabled on an MST stream. This can result
in blank displays.

[How]
As a work around, always enable DSC on docks exhibiting this issue. The
flag to indicate the use of DSC for MST streams on a USB4 dock is set
during detection of the dock and only cleared when the USB4 dock is
disconnected.

Subject: drm/amd/display: Fix dual eDP abnormal display issue

[WHY]
Driver use primary eDP link stream as the condition
to enable fastboot or not.
In dual eDP case, set second screen only,
this would cause slave eDP timing to be used on primary one.

[HOW]
Add a check for unmatched eDP link stream.

Subject: drm/amd/display: Skip vendor specific LTTPR w/a outside link training

[Why]
Vendor specific link rate toggle workaround should not be
applied outside of link training scenario, such as when
outputting PHY test pattern.

[How]
Add flag to indicate when link training is occuring.
Make workaround a no-op when flag is not set.

Subject: drm/amd/display: Add 16ms AUX RD interval W/A for specific LTTPR

[Why]
Certain display configurations require an extra delay before
reading lane status with certain LTTPR.

[How]
Add temporary workaround to force AUX RD interval to
16ms for CR and EQ. Needs to be refactored later.

Subject: drm/amd/display: add connector type check for CRC source set

[Why]
IGT bypass test will set crc source as DPRX,and display DM didn`t check
connection type, it run the test on the HDMI connector ,then the kernel
will be crashed because aux->transfer is set null for HDMI connection.
This patch will skip the invalid connection test and fix kernel crash issue.

[How]
Check the connector type while setting the pipe crc source as DPRX or
auto,if the type is not DP or eDP, the crtc crc source will not be set
and report error code to IGT test,IGT will show the this subtest as no
valid crtc/connector combinations found.

Subject: drm/amdgpu: adjust the kfd reset sequence in reset sriov function

This change revert previous commits:
9f4f2c1a3524 ("drm/amd/amdgpu: fix the kfd pre_reset sequence in sriov")
271fd38ce56d ("drm/amdgpu: move kfd post_reset out of reset_sriov function")

This change moves the amdgpu_amdkfd_pre_reset to an earlier place
in amdgpu_device_reset_sriov, presumably to address the sequence issue
that the first patch was originally meant to fix.

Some register access(GRBM_GFX_CNTL) only be allowed on full access
mode. Move kfd_pre_reset and  kfd_post_reset back inside reset_sriov
function.

Fixes: 9f4f2c1a3524 ("drm/amd/amdgpu: fix the kfd pre_reset sequence in sriov")
Fixes: 271fd38ce56d ("drm/amdgpu: move kfd post_reset out of reset_sriov function")

Subject: drm/amdkfd: replace asic_name with amdgpu_asic_name

device_info->asic_name and amdgpu_asic_name[adev->asic_type] both
provide asic name strings, with the only difference being casing.
Remove asic_name from device_info and replace sysfs entry with lowercase
amdgpu_asic_name[]. Ensures string is null-terminated so that this
doesn't break if dev->node_props.name ever gets set anywhere else.

From f0dc99a6f742bce9f5e45a6ca48bc4f1f8c6bac8 Mon Sep 17 00:00:00 2001
From: Graham Sider <Graham.Sider@amd.com>
Date: Wed, 17 Nov 2021 17:32:37 -0500
Subject: drm/amdkfd: add kfd_device_info_init function

Initializes kfd->device_info given either asic_type (enum) if GFX
version is less than GFX9, or GC IP version if greater. Also takes in vf
and the target compiler gfx version. Uses SDMA version to determine
num_sdma_queues_per_engine.

Convert device_info to a non-pointer member of kfd, change references
accordingly.

Change unsupported asic condition to only probe f2g, move device_info
initialization post-switch.

From 2c1f19b3272c0c09184b1cce592a91dc34a83506 Mon Sep 17 00:00:00 2001
From: Graham Sider <Graham.Sider@amd.com>
Date: Thu, 18 Nov 2021 16:09:58 -0500
Subject: drm/amdkfd: remove hardcoded device_info structs

With device_info initialization being handled in kfd_device_info_init,
these structs may be removed. Also add comments to help matching IP
versions to asic names.

Subject: drm/amdkfd: process_info lock not needed for svm

process_info->lock is used to protect kfd_bo_list, vm_list_head, n_vms
and userptr valid/inval list, svm_range_restore_work and
svm_range_set_attr don't access those, so do not need to take
process_info lock. This will avoid potential circular locking issue.

Subject: drm/amdgpu: update fw_load_type module parameter doc to match code

amdgpu_ucode_get_load_type() does not interpret this parameter as
documented.  It is ignored for many ASIC types (which presumably
only support one load_type), and when not ignored it is only used
to force direct loading instead of PSP loading.  SMU loading is
only available for ASICs for which the parameter is ignored.

Subject: drm/amd/display: Allow DSC on supported MST branch devices

[Why]
When trying to lightup two 4k60 non-DSC displays behind a branch device
that supports DSC we can't lightup both at once due to bandwidth
limitations - each requires 48 VCPI slots but we only have 63.

[How]
The workaround already exists in the code but is guarded by a CONFIG
that cannot be set by the user and shouldn't need to be.

Check for specific branch device IDs to device whether to enable
the workaround for multiple display scenarios.

Subject: drm/amd/display: Fix for the no Audio bug with Tiled Displays

[WHY]
It seems like after a series of plug/unplugs we end up in a situation
where tiled display doesnt support Audio.

[HOW]
The issue seems to be related to when we check streams changed after an
HPD, we should be checking the audio_struct as well to see if any of its
values changed.

Subject: drm/amd/display: Add work around for tunneled MST.

[Why]
Certain USB4 docks do not seem to be able to handle disabling
DSC once it has been enabled on an MST stream. This can result
in blank displays.

[How]
As a work around, always enable DSC on docks exhibiting this issue. The
flag to indicate the use of DSC for MST streams on a USB4 dock is set
during detection of the dock and only cleared when the USB4 dock is
disconnected.

Subject: drm/amd/display: add connector type check for CRC source set

[Why]
IGT bypass test will set crc source as DPRX,and display DM didn`t check
connection type, it run the test on the HDMI connector ,then the kernel
will be crashed because aux->transfer is set null for HDMI connection.
This patch will skip the invalid connection test and fix kernel crash issue.

[How]
Check the connector type while setting the pipe crc source as DPRX or
auto,if the type is not DP or eDP, the crtc crc source will not be set
and report error code to IGT test,IGT will show the this subtest as no
valid crtc/connector combinations found.

Subject: drm/amdgpu: adjust the kfd reset sequence in reset sriov function

This change revert previous commits:
9f4f2c1a3524 ("drm/amd/amdgpu: fix the kfd pre_reset sequence in sriov")
271fd38ce56d ("drm/amdgpu: move kfd post_reset out of reset_sriov function")

This change moves the amdgpu_amdkfd_pre_reset to an earlier place
in amdgpu_device_reset_sriov, presumably to address the sequence issue
that the first patch was originally meant to fix.

Some register access(GRBM_GFX_CNTL) only be allowed on full access
mode. Move kfd_pre_reset and  kfd_post_reset back inside reset_sriov
function.

Fixes: 9f4f2c1a3524 ("drm/amd/amdgpu: fix the kfd pre_reset sequence in sriov")
Fixes: 271fd38ce56d ("drm/amdgpu: move kfd post_reset out of reset_sriov function")

process_info->lock is used to protect kfd_bo_list, vm_list_head, n_vms
and userptr valid/inval list, svm_range_restore_work and
svm_range_set_attr don't access those, so do not need to take
process_info lock. This will avoid potential circular locking issue.

Subject: drm: Return error codes from struct drm_driver.gem_create_object

GEM helper libraries use struct drm_driver.gem_create_object to let
drivers override GEM object allocation. On failure, the call returns
NULL.

Change the semantics to make the calls return a pointer-encoded error.
This aligns the callback with its callers. Fixes the ingenic driver,
which already returns an error pointer.

Also update the callers to handle the involved types more strictly.

This workarounds are causing hangs, because I missed the fact that it
needs to be enabled for all cases and disabled when doing a resolve
pass.

So KMD only needs to whitelist it and UMD will be the one setting it
on per case.

This reverts commit 28ec02c9cbebf3feeaf21a59df9dfbc02bda3362.

Subject: drm/amdgpu: Fix a NULL pointer dereference in
 amdgpu_connector_lcd_native_mode()

In amdgpu_connector_lcd_native_mode(), the return value of
drm_mode_duplicate() is assigned to mode, and there is a dereference
of it in amdgpu_connector_lcd_native_mode(), which will lead to a NULL
pointer dereference on failure of drm_mode_duplicate().

Fix this bug add a check of mode.

This bug was found by a static analyzer. The analysis employs
differential checking to identify inconsistent security operations
(e.g., checks or kfrees) between two code paths and confirms that the
inconsistent operations are not recovered in the current function or
the callers, so they constitute bugs.

Note that, as a bug found by static analysis, it can be a false
positive or hard to trigger. Multiple researchers have cross-reviewed
the bug.

Builds with CONFIG_DRM_AMDGPU=m show no new warnings, and
our static analyzer no longer warns about this code.

Subject: drm/amd/display: Use oriented source size when checking cursor
 scaling

dm_check_crtc_cursor() doesn't take into account plane transforms when
calculating plane scaling, this can result in false positives.

For example, if there's an output with resolution 3840x2160 and the
output is rotated 90 degrees, CRTC_W and CRTC_H will be 3840 and 2160,
respectively, but SRC_W and SRC_H will be 2160 and 3840, respectively.

Since the cursor plane usually has a square buffer attached to it, the
dm_check_crtc_cursor() will think that there's a scale factor mismatch
even though there isn't really.

This fixes an issue where kwin fails to use hardware plane transforms.

Changes since version 1:
- s/orientated/oriented/g

In radeon_driver_open_kms(), radeon_vm_bo_add() is assigned to
vm->ib_bo_va and passes and used in radeon_vm_bo_set_addr(). In
radeon_vm_bo_set_addr(), there is a dereference of vm->ib_bo_va,

Fix this bug by adding a check of vm->ib_bo_va.

Invalidate IC cache through pipe control command as part of the ctx

v2:
 - Move pipe control from xcs indirect context to the rcs indirect

Content-Type: text/plain; charset=UTF-8

Commit 7120a447c7fe ("drm/ttm: Double check mem_type of BO while eviction")
made ttm_bo_evict_swapout_allowable() function actually check the
placement, but we always used a dummy placement in ttm_bo_swapout.

Fix this by using the real placement instead.

Subject: treewide: Add missing includes masked by cgroup -> bpf dependency
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

cgroup.h (therefore swap.h, therefore half of the universe)
includes bpf.h which in turn includes module.h and slab.h.
Since we're about to get rid of that dependency we need
to clean things up.

v2: drop the cpu.h include from cacheinfo.h, it's not necessary
and it makes riscv sensitive to ordering of include files.

Subject: drm/i915: Fix error pointer dereference in i915_gem_do_execbuffer()

Originally "out_fence" was set using out_fence = sync_file_create() but
which returns NULL, but now it is set with out_fence = eb_requests_create()
which returns error pointers.  The error path needs to be modified to
avoid an Oops in the "goto err_request;" path.

Subject: drm/rcar: stop using 'imply' for dependencies

The meaning of the 'imply' keyword has changed recently, and neither the
old meaning (select the symbol if its dependencies are met) nor the new
meaning (enable it by default, but let the user set any other setting)
is what we want here.

Work around this by adding two more Kconfig options that lead to
the correct behavior: if DRM_RCAR_USE_CMM and DRM_RCAR_USE_LVDS
are enabled, that portion of the driver becomes usable, and no
configuration results in a link error.

This avoids a link failure:

Subject: drm: rcar-du: Fix CRTC timings when CMM is used

When the CMM is enabled, an offset of 25 pixels must be subtracted from
the HDS (horizontal display start) and HDE (horizontal display end)
registers. Fix the timings calculation, and take this into account in
the mode validation.

This fixes a visible horizontal offset in the image with VGA monitors.
HDMI monitors seem to be generally more tolerant to incorrect timings,
but may be affected too.

Subject: drm: rcar-du: crtc: Support external DSI dot clock

On platforms with an external clock, both the group and crtc must be
handled accordingly to correctly pass through the external clock and
configure the DU to use the external rate.

The CRTC support was missed while adding the DSI support on the r8a779a0
which led to the output clocks being incorrectly determined.

Ensure that when a CRTC is routed through the DSI encoder, the external
clock is used without any further divider being applied.

Subject: drm/msm: Allocate msm_drm_private early and pass it as driver data

In preparation for registering the mdss interrupt controller earlier,
move the allocation of msm_drm_private from component bind time to
msm_drv probe; this also allows us to use the devm variant of kzalloc.

Since it is not right to allocate the drm_device at probe time (as
it should exist only when all components are bound, and taken down
when components get cleaned up), the only way to make this happen is
to pass a pointer to msm_drm_private as driver data (like done in
many other DRM drivers), instead of one to drm_device like it's
currently done in this driver.

This is also simplifying some bind/unbind functions around drm/msm,
as some of them are using drm_device just to grab a pointer to the
msm_drm_private structure, which we now retrieve in one call.

Subject: drm/msm: Initialize MDSS irq domain at probe time

Since commit 8f59ee9a570c ("drm/msm/dsi: Adjust probe order"), the
DSI host gets initialized earlier, but this caused unability to probe
the entire stack of components because they all depend on interrupts
coming from the main `mdss` node (mdp5, or dpu1).

To fix this issue, move mdss device initialization (which include irq
domain setup) to msm_mdev_probe() time, as to make sure that the
interrupt controller is available before dsi and/or other components try
to initialize, finally satisfying the dependency.

Fixes: 8f59ee9a570c ("drm/msm/dsi: Adjust probe order")

Subject: drm/i915: Introduce new macros for i915 PTE

Certain functions within i915 uses macros that are defined for
specific architectures by the mmu, such as _PAGE_RW and _PAGE_PRESENT
(Some architectures don't even have these macros defined, like ARM64).

Instead of re-using bits defined for the CPU, we should use bits
defined for i915. This patch introduces two new 64 bit macros,
GEN8_PAGE_PRESENT and GEN8_PAGE_RW, to check for bits 0 and 1 and, to
replace all occurrences of _PAGE_RW and _PAGE_PRESENT within i915.

v2(Michael Cheng): Use GEN8_ instead of I915_

Subject: drm/rockchip: use generic fbdev setup

The Rockchip fbdev code does not add anything compared to
drm_fbdev_generic_setup(); the one custom function for .fb_mmap does the
same thing as gem_prime_mmap which is called by the helper.

Subject: drm/rockchip: pass 0 to drm_fbdev_generic_setup()

Allow drm_fbdev_generic_setup() to pick the default bpp value for the
framebuffer.

This has no functional impact because the default is 32, given that
mode_config.preferred_depth is not set for Rockchip.

Subject: drm/panel: Update Boe-tv110c9m and Inx-hj110iz initial code

At present, we have enough panel to confirm the effect,
update the initial code to achieve the best effect.
Such as gamma, Gop timing. They are all minor modifications
and doesn't affect the lighting of the panel.

a)Boe-tv110c9m panel Optimized touch horizontal grain.
b)Inx-hj110iz panel Optimized GOP timing and gamma.

Subject: drm/bridge: parade-ps8640: Add backpointer to drm_device in
 drm_dp_aux

When we added the support for the AUX channel in commit 13afcdd7277e
("drm/bridge: parade-ps8640: Add support for AUX channel") we forgot
to set "drm_dev" to avoid the warning splat at the beginning of
drm_dp_aux_register(). Since everything was working I guess I never
noticed the splat when testing against mainline. In any case, it's
easy to fix. This is basically just like commit 6cba3fe43341 ("drm/dp:
Add backpointer to drm_device in drm_dp_aux") but just for the
parade-ps8640.

Subject: drm/amd/display: Fix DPIA outbox timeout after S3/S4/reset

[Why]
The HW interrupt gets disabled after S3/S4/reset so we don't receive
notifications for HPD or AUX from DMUB - leading to timeout and
black screen with (or without) DPIA links connected.

[How]
Re-enable the interrupt after S3/S4/reset like we do for the other
DC interrupts.

Guard both instances of the outbox interrupt enable or we'll hang
during restore on ASIC that don't support it.

Subject: drm/amd/display: Prevent PSR disable/reenable in HPD IRQ

[Why]
When HPD IRQ occurs, it triggers a PSR disable and reenable
directly through dc layer.
Since it does not pass through the power layer, the layer
that tracks whether PSR is enabled or disabled and which
masks are set, this layer is now out of sync with the real
PSR state in FW.
Theoretically PSR can be enabled during hw programming

[How]
Check if PSR is enabled before doing PSR disable/reenable.

Subject: drm/amd/display: Fix bug in debugfs crc_win_update entry

[Why]
crc_rd_wrk shouldn't be null in crc_win_update_set(). Current programming
logic is inconsistent in crc_win_update_set().

[How]
Initially, return if crc_rd_wrk is NULL. Later on, we can use member of
crc_rd_wrk safely.

We shouldn't be accessing res_pool funcs from DM level,
therefore, we should create API and let the flow
be done in DC level.

We create new interface dp_get_link_enc to access and get the correct link_enc

To avoid hanging RDPCSPIPE when INTERCEPTB isn't set.

DMCUB owns control of that bit so DMCUB should manage returning the
information driver needs for link encoder control.

[How]
Add a new DMCUB command to return dp alt disable and dp4 information.

Subject: drm/amd/display: Fix out of bounds access on DNC31 stream encoder
 regs

[Why]
During dcn31_stream_encoder_create, if PHYC/D get remapped to F/G on B0
then we'll index 5 or 6 into a array of length 5 - leading to an
access violation on some configs during device creation.

[How]
Software won't be touching PHYF/PHYG directly, so just extend the
array to cover all possible engine IDs.

Even if it does by try to access one of these registers by accident
the offset will be 0 and we'll get a warning during the access.

Subject: drm/amdgpu: update drm_display_info correctly when the edid is read

drm_display_info is updated by drm_get_edid() or
drm_connector_update_edid_property(). In the amdgpu driver it is almost
always updated when the edid is read in amdgpu_connector_get_edid(),
but not always.  Change amdgpu_connector_get_edid() and
amdgpu_connector_free_edid() to keep drm_display_info updated.

Subject: drm/amdgpu: replace drm_detect_hdmi_monitor() with
 drm_display_info.is_hdmi

Once EDID is parsed, the monitor HDMI support information is available
through drm_display_info.is_hdmi. The amdgpu driver still calls
drm_detect_hdmi_monitor() to retrieve the same information, which
is less efficient. Change to drm_display_info.is_hdmi

This is a TODO task in Documentation/gpu/todo.rst

Subject: drm/msm/gpu: Don't allow zero fence_id

Elsewhere we treat zero as "no fence" and __msm_gem_submit_destroy()
skips removal from fence_idr.  We could alternately change this to use
negative values for "no fence" but I think it is more clear to not allow
zero as a valid fence_id.

Subject: drm/msm/dpu: Remove encoder->enable() hack

encoder->commit() was being misused because there were some global
resources which needed to be tweaked in encoder->enable() which were not
accessible in dpu_encoder.c. That is no longer true and the redirect
serves no purpose any longer. So remove the indirection.

From 8a3b4c17f863cde8e8743edd8faffe916c49b960 Mon Sep 17 00:00:00 2001
From: Kuogee Hsieh <quic_khsieh@quicinc.com>
Date: Tue, 7 Dec 2021 15:15:33 -0800
Subject: drm/msm/dp: employ bridge mechanism for display enable and disable

Currently the msm_dp_*** functions implement the same sequence which would
happen when drm_bridge is used. hence get rid of this intermediate layer
and align with the drm_bridge usage to avoid customized implementation.

Signed-off-by: Kuogee Hsieh <quic_khsieh@quicinc.com>

Changes in v2:
-- revise commit text
-- rename dp_bridge to msm_dp_bridge
-- delete empty functions

Changes in v3:
-- replace kzalloc() with devm_kzalloc()
-- replace __dp_display_enable() with dp_display_enable()
-- replace __dp_display_disable() with dp_display_disable()

Changes in v4:
-- msm_dp_bridge_init() called from msm_dp_modeset_init() same as dsi

Changes in v5:
-- delete attach, mode_fixup and pre_enable from dp_bridge_ops

Changes in v6:
-- rebase on msm-next-plus-fixes branch

Subject: drm/msm/dpu: drop scaler config from plane state

Scaler and pixel_ext configuration does not contain a long living state,
it is used only during plane update, so remove these two fields from
dpu_plane_state and allocate them on stack.

The _dpu_hw_sspp_setup_scaler3 (hw_sspp->setup_scaler) does not use pe
argument. Let's remove it while we are cleaning scaled configuration.

bitshifts.

Subject: drm: omapdrm: Export correct scatterlist for TILER backed BOs

Memory of BOs backed by TILER is not contiguous, but omap_gem_map_dma_buf()
exports it like it is. This leads to (possibly) invalid memory accesses if
another device imports such a BO.

Fix that by providing sg that correctly describes TILER memory layout.
Align TILER allocations to page, so importer to be able to correctly set
its MMU if have one. Set export size accounting for the alignment. Also,
make sure to destroy sg on unpin, as it is no longer valid.

Tested on Motorola Droid4 by using GPU (sgx540) to render.

Subject: drm/omap: add sanity plane state check

Call drm_atomic_helper_check_plane_state() from the plane
atomic_check() callback in order to add plane state sanity
checking.

It will permit filtering out totally bad scaling factors, even
if the real check are done later in the atomic commit.

Calling drm_atomic_helper_check_plane_state() also sets
plane_state->visible which will be useful when dynamically
assigning hw overlays to planes.

Subject: drm/omap: Add ability to check if requested plane modes can be
 supported

We currently assume that an overlay has the same maximum width and
maximum height as the overlay manager. This assumption is incorrect. On
some variants the overlay manager maximum width is twice the maximum
width that the overlay can handle. We need to add the appropriate data
per variant as well as export a helper function to retrieve the data so
check can be made dynamically in omap_plane_atomic_check().

Subject: drm/omap: Add ovl checking funcs to dispc_ops

In order to be able to dynamically assign overlays to planes we need to
be able to asses the overlay capabilities.

Add a helper function to be able to retrieve the supported capabilities
of an overlay.

And export the function to check if a fourcc is supported on a given
overlay.

Subject: drm/omap: introduce omap_hw_overlay

Split out the hardware overlay specifics from omap_plane.
To start, the hw overlays are statically assigned to planes.

The goal is to eventually assign hw overlays dynamically to planes
during plane->atomic_check() based on requested caps (scaling, YUV,
etc). And then perform hw overlay re-assignment if required.

Subject: drm/omap: omap_plane: subclass drm_plane_state

In preparation to add omap plane state specific extensions we need to
subclass drm_plane_state and add the relevant helpers.

The addition of specific extension will be done separately.

From: Benoit Parrot <bparrot@ti.com>

Subject: drm/omap: Add global state as a private atomic object

Global shared resources (like hw overlays) for omapdrm are implemented
as a part of atomic state using the drm_private_obj infrastructure
available in the atomic core.

omap_global_state is introduced as a drm atomic private object. The two
funcs omap_get_global_state() and omap_get_existing_global_state() are
the two variants that will be used to access omap_global_state.

drm_mode_config_init() needs to be called earlier because it
creates/initializes the private_obj link list maintained by the atomic
framework. The private_obj link list has to exist prior to calling
drm_atomic_private_obj_init(). Similarly the cleanup handler are
reordered appropriately.

Subject: drm/omap: dynamically assign hw overlays to planes

(re)assign the hw overlays to planes based on required caps, and to
handle situations where we could not modify an in-use plane.

This means all planes advertise the superset of formats and properties.
Userspace must (as always) use atomic TEST_ONLY step for atomic updates,
as not all planes may be available for use on every frame.

The mapping of hwoverlays to plane is stored in omap_global_state, so
that state updates are atomically committed in the same way that
plane/etc state updates are managed.  This is needed because the
omap_plane_state keeps a pointer to the hwoverlay, and we don't want
global state to become out of sync with the plane state if an atomic
update fails, we hit deadlock/ backoff scenario, etc.  The use of
global_state_lock keeps multiple parallel updates which both re-assign
hwoverlays properly serialized.

Subject: drm/omap: Add a 'right overlay' to plane state

If the drm_plane has a source width that's greater than the max width
supported by a single hw overlay, then we assign a 'r_overlay' to it in
omap_plane_atomic_check().

Both overlays should have the capabilities required to handle the source
framebuffer. The only parameters that vary between the left and right
hwoverlays are the src_w, crtc_w, src_x and crtc_x as we just even chop
the fb into left and right halves.

We also take care of not creating odd width size when dealing with YUV
formats.

Since both halves need to be 'appear' side by side the zpos is
recalculated when dealing with dual overlay cases so that the other
planes zpos is consistent.

Depending on user space usage it is possible that on occasion the number
of requested planes exceeds the numbers of overlays required to display
them. In that case a failure would be returned for the plane that cannot
be handled at that time. It is up to user space to make sure the H/W
resource are not over-subscribed.

Subject: omapdrm: dss: mark runtime PM functions __maybe_unused

Using the SET_RUNTIME_PM_OPS() macro causes a warning about the
referenced functions when they are marked static but not __maybe_unused:

drivers/gpu/drm/omapdrm/dss/dss.c:1572:12: error: unused function 'dss_runtime_suspend' [-Werror,-Wunused-function]
drivers/gpu/drm/omapdrm/dss/dss.c:1584:12: error: unused function 'dss_runtime_resume' [-Werror,-Wunused-function]
drivers/gpu/drm/omapdrm/dss/dispc.c:4845:12: error: unused function 'dispc_runtime_suspend' [-Werror,-Wunused-function]
drivers/gpu/drm/omapdrm/dss/dispc.c:4860:12: error: unused function 'dispc_runtime_resume' [-Werror,-Wunused-function]

The scratch page might not be allocated in LMEM(like on DG2), so instead
of using that as the deciding factor for where the paging structures
live, let's just query the pt before mapping it.

No need to insert PTEs for the PTE window itself, also foreach expects a

Subject: drm/syncobj: Deal with signalled fences in drm_syncobj_find_fence.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

dma_fence_chain_find_seqno only ever returns the top fence in the
chain or an unsignalled fence. Hence if we request a seqno that
is already signalled it returns a NULL fence. Some callers are
not prepared to handle this, like the syncobj transfer functions
for example.

This behavior is "new" with timeline syncobj and it looks like
not all callers were updated. To fix this behavior make sure
that a successful drm_sync_find_fence always returns a non-NULL
fence.

v2: Move the fix to drm_syncobj_find_fence from the transfer
    functions.

Fixes: ea569910cbab ("drm/syncobj: add transition iotcls between binary and timeline v2")

Subject: drm/bridge: sn65dsi86: defer if there is no dsi host

Otherwise we don't get another shot at it if the bridge probes before
the dsi host is registered.  It seems like this is what *most* (but not
all) of the other bridges do.

It looks like this was missed in the conversion to attach dsi host at
probe time.

Subject: drm/msm/dsi: fix initialization in the bonded DSI case

Commit 739b4e7756d3 ("drm/msm/dsi: Fix an error code in
msm_dsi_modeset_init()") changed msm_dsi_modeset_init() to return an
error code in case msm_dsi_manager_validate_current_config() returns
false. However this is not an error case, but a slave DSI of the bonded
DSI link. In this case msm_dsi_modeset_init() should return 0, but just
skip connector and bridge initialization.

To reduce possible confusion, drop the
msm_dsi_manager_validate_current_config() function, and specif 'bonded
&& !master' condition directly in the msm_dsi_modeset_init().

Originally "out_fence" was set using out_fence = sync_file_create() but
which returns NULL, but now it is set with out_fence = eb_requests_create()
which returns error pointers.  The error path needs to be modified to
avoid an Oops in the "goto err_request;" path.

Subject: drm/amd/display: Fix DPIA outbox timeout after S3/S4/reset

[Why]
The HW interrupt gets disabled after S3/S4/reset so we don't receive
notifications for HPD or AUX from DMUB - leading to timeout and
black screen with (or without) DPIA links connected.

[How]
Re-enable the interrupt after S3/S4/reset like we do for the other
DC interrupts.

Guard both instances of the outbox interrupt enable or we'll hang
during restore on ASIC that don't support it.

Fixes: 6eff272dbee7ad ("drm/amd/display: Fix DPIA outbox timeout after GPU reset")

Subject: Revert "drm/fb-helper: improve DRM fbdev emulation device names"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This reverts commit b3484d2b03e4c940a9598aa841a52d69729c582a.

That change attempted to improve the DRM drivers fbdev emulation device
names to avoid having confusing names like "simpledrmdrmfb" in /proc/fb.

But unfortunately, there are user-space programs such as pm-utils that
match against the fbdev names and so broke after the mentioned commit.

Since the names in /proc/fb are used by tools that consider it an uAPI,
let's restore the old names even when this lead to silly names like the
one mentioned above.

Subject: drm/i915/gtt/xehpsdv: move scratch page to system memory

On some platforms the hw has dropped support for 4K GTT pages when
dealing with LMEM, and due to the design of 64K GTT pages in the hw, we
can only mark the *entire* page-table as operating in 64K GTT mode,
since the enable bit is still on the pde, and not the pte. And since we
we still need to allow 4K GTT pages for SMEM objects, we can't have a
"normal" 4K page-table with scratch pointing to LMEM, since that's
undefined from the hw pov. The simplest solution is to just move the 64K
scratch page to SMEM on such platforms and call it a day, since that
should work for all configurations.

Subject: drm/i915: enforce min page size for scratch
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If the device needs 64K minimum GTT pages for device local-memory,
like on XEHPSDV, then we need to fail the allocation if we can't
meet it, instead of falling back to 4K pages, otherwise we can't
safely support the insertion of device local-memory pages for
this vm, since the HW expects the correct physical alignment and
size for every PTE, if we mark the page-table as 64K GTT mode.

Subject: drm/i915/pmu: Wait longer for busyness data to be available from GuC

live_engine_busy_stats waits for busyness to start ticking before
sampling busyness for the test sample duration. The wait accesses an
MMIO register and the uncore call to read it takes up to 3 ms in the
worst case. This can result in the wait timing out since the MMIO read
itself consumes up the timeout of 500us. Increase the timeout to a
larger value of 10ms to account for the MMIO read time.

Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/4536

Subject: drm/vmwgfx: Remove the dedicated memory accounting

vmwgfx shared very elaborate memory accounting with ttm. It was moved
from ttm to vmwgfx in change
f07069da6b4c ("drm/ttm: move memory accounting into vmwgfx v4")
but because of complexity it was hard to maintain. Some parts of the code
weren't freeing memory correctly and  some were missing accounting all
together. While those would be fairly easy to fix the fundamental reason
for memory accounting in the driver was the ability to invoke shrinker
which is part of TTM code as well (with support for unified memory
hopefully coming soon).

That meant that vmwgfx had a lot of code that was either unused or
duplicating code from TTM. Removing this code also prevents excessive
calls to global swapout which were common during memory pressure
because both vmwgfx and TTM would invoke the shrinker when memory
usage reached half of RAM.

Subject: drm/vmwgfx: Add a debug callback to mobid resource manager

Mob/GMR id resource manager was lacking the debug print callback
which meant that during memory errors we weren't getting the details
which are needed to fix those errors.

Kernel logs need to contain the information about used/max pages
by the Mob/GMR id resource manager as well as the maximum number
of id's they're allowed to allocate.

Instead of hardcoding the VMware's PCI ID the code should be using the
public define for it. There's no functional change, it just makes
it obvious what we're dealing with.

Subject: drm/vmwgfx: Implement DRIVER_GEM

This is initial change adding support for DRIVER_GEM to vmwgfx. vmwgfx
was written before GEM and has always used TTM. Over the years the
TTM buffers started inherting from GEM objects but vmwgfx never
implemented GEM making it quite awkward. We were directly setting
variables in GEM objects to not make DRM crash.

This change brings vmwgfx inline with other DRM drivers and allows us
to use a lot of DRM helpers which have depended on drivers with GEM
support.

Due to historical reasons vmwgfx splits the idea of a buffer and surface
which makes it a littly tricky since either one can be used in most
of our ioctl's which take user space handles. For now our BO's are
GEM objects and our surfaces are opaque objects which are backed by
GEM objects. In the future I'd like to combine those into a single
BO but we don't want to break any of our existing ioctl's so it will
take time to do it in a non-destructive way.

Subject: drm/vmwgfx: Implement create_handle on drm_framebuffer_funcs

The fb handle code assumes it deals with GEM objects. Because vmwgfx
buffer objects were not actually GEM objects we were not able to
implement that interface. Now that vmwgfx supports GEM buffer objects
we can trivially implement create_handle for buffer object backed
framebuffers.
Among others this gets IGT's kms_getfb test passing.

Subject: drm/vmwgfx: Update device headers for GL43

Update the headers for GL43 userspace works that landed in Mesa3D. Also
update the license headers to conform to the kernel guidelines.

For GL43 the virtual device got D3D11.1 support with some GL extensions.

Subject: drm/vmwgfx: support SVGA_3D_CMD_DX_DEFINE_RASTERIZER_STATE_V2 command

This is going to be required for setting the sample count when
rendering with no attachments.
Also cleans up view handling (should fix depthstencil_v2).

Subject: drm/vmwgfx: Allow checking for gl43 contexts

To make sure we're running on top of hardware that can support
GL4.3 we need to add a way of querying for those capabilities.
DRM_VMW_PARAM_GL43 allows userspace to check for presence of
GL4.3 capable contexts.

Subject: drm/vmwgfx: Remove usage of MOBFMT_RANGE

Using MOBFMT_RANGE in the early days of guest backed objects was a major
performance win but that has changed a lot since. There's no more
a performance reason to use MOBFMT_RANGE. The device can/will still
profit from the pages being contiguous but marking them as MOBFMT_RANGE
no longer matters.
Benchmarks (e.g. heaven, valley) show that creating page tables
for mob memory is actually faster than using mobfmt ranges.

Subject: drm/vmwgfx: Bump the minor version

v2: Old userspace doesn't like 3.x.x and we'd like to keep it working,
so lets just bump the minor version until we have no choice.

With GEM, GL4.3, stats and removal of a lot of old code it's time to bump
the minor version of the driver.

Subject: drm/sprd: add Unisoc's drm kms master

Adds drm support for the Unisoc's display subsystem.

This is drm kms driver, this driver provides support for the
application framework in Android, Yocto and more.

Application framework can access Unisoc's display internal
peripherals through libdrm or libkms, it's test ok by modetest
(DRM/KMS test tool) and Android HWComposer.

v4:
  - Move the devm_drm_dev_alloc to master_ops->bind function.
  - The managed drmm_mode_config_init() it is no longer necessary for drivers to explicitly call drm_mode_config_cleanup, so delete it.

v5:
  - Remove subdir-ccflgas-y for Makefile.
  - Keep the selects sorted by alphabet for Kconfig.

Subject: drm/sprd: add Unisoc's drm display controller driver

Adds DPU(Display Processor Unit) support for the Unisoc's display
subsystem.
It's support multi planes, scaler, rotation, PQ(Picture Quality) and more.

v2:
  - Use drm_xxx to replace all DRM_XXX.
  - Use kzalloc to replace devm_kzalloc for sprd_dpu structure init.

v3:
  - Remove dpu_layer stuff layer and commit layers by aotmic_update

v4:
  - Use drmm_helpers to allocate crtc and planes.
  - Move rotation enum definitions to crtc layer reg bitfields.
  - Move allocate crtc and planes to bind function.

v5:
  - Fix the checkpatch warnings.
  - Use mode_set_nofb instead of mode_valid callback.
  - Follow the OF-Graph bindings, use of_graph_get_port_by_id
    instead of of_parse_phandle.
  - Use zpos to represent the layer position.
  - Rebase to last drm misc branch.

v6:
  - Disable and clear interrupts before register dpu IRQ
  - Init dpi config used by crtc_state->adjusted_mode on mode_set_nofb
  - Remove enable_irq and disable_irq function call.
  - Remove drm_format_info function call.

v7:
  - Remove iommu error interrupt handling function.

Subject: drm/sprd: add Unisoc's drm mipi dsi&dphy driver

Adds dsi host controller support for the Unisoc's display subsystem.
Adds dsi phy support for the Unisoc's display subsystem.
Only MIPI DSI Displays supported, DP/TV/HMDI will be support
in the feature.

v1:
  - Remove dphy and dsi graph binding, merge the dphy driver into the dsi.

v2:
  - Use drm_xxx to replace all DRM_XXX.
  - Use kzalloc to replace devm_kzalloc for sprd_dsi structure init.

v4:
  - Use drmm_helpers to allocate encoder.
  - Move allocate encoder and connector to bind function.

v5:
  - Drop the dsi ip file prefix.
  - Fix the checkpatch warnings.
  - Add Signed-off-by for dsi&dphy patch.
  - Use the mode_flags of mipi_dsi_device to setup crtc DPI and EDPI mode.

v6:
  - Redesign the way to access the dsi register.
  - Reduce the dsi_context member variables.

v7:
  - Fix codeing style issue by checkpatch.
  - Drop the pll registers structure define.
  - Use bridge API instead of drm panel API.
  - Register mipi_dsi_host on probe phase;
  - Remove some unused function.

v8:
  - Fix missing signed-off-by.
  - Move component_add to dsi_host.attach callback.

Subject: drm/i915/uc: Allow platforms to have GuC but not HuC

It is possible for platforms to require GuC but not HuC firmware.
Also, the firmware versions for GuC and HuC advance independently. So
split the macros up to allow the lists to be maintained separately.

Subject: drm/i915: Don't disable interrupts and pretend a lock as been
 acquired in __timeline_mark_lock().

This is a revert of commits
   d67739268cf0e ("drm/i915/gt: Mark up the nested engine-pm timeline lock as irqsafe")
   6c69a45445af9 ("drm/i915/gt: Mark context->active_count as protected by timeline->mutex")
   6dcb85a0ad990 ("drm/i915: Hold irq-off for the entire fake lock period")

The existing code leads to a different behaviour depending on whether
lockdep is enabled or not. Any following lock that is acquired without
disabling interrupts (but needs to) will not be noticed by lockdep.

This it not just a lockdep annotation but is used but an actual mutex_t
that is properly used as a lock but in case of __timeline_mark_lock()
lockdep is only told that it is acquired but no lock has been acquired.

It appears that its purpose is just satisfy the lockdep_assert_held()
check in intel_context_mark_active(). The other problem with disabling
interrupts is that on PREEMPT_RT interrupts are also disabled which
leads to problems for instance later during memory allocation.

Add a CONTEXT_IS_PARKING bit to intel_engine_cs and set_bit/clear_bit it
instead of mutex_acquire/mutex_release. Use test_bit in the two
identified spots which relied on the lockdep annotation.

Subject: drm/i915: Fix coredump of perma-pinned vmas
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When updating the error capture code and introducing vma snapshots,
we introduced code to hold the vma in memory while capturing it,
calling i915_active_acquire_if_busy(). Now that function isn't relevant
for perma-pinned vmas and caused important vmas to be dropped from the
coredump. Like for example the GuC log.

Fix this by instead requiring those vmas to be pinned while capturing.

Tested by running the initial subtests of the gem_exec_capture igt test
with GuC submission enabled and verifying that a GuC log blob appears
in the output.

Subject: drm/mediatek: hdmi: Perform NULL pointer check for mtk_hdmi_conf

In commit 41ca9caaae0b
("drm/mediatek: hdmi: Add check for CEA modes only") a check
for CEA modes was added to function mtk_hdmi_bridge_mode_valid()
in order to address possible issues on MT8167;
moreover, with commit c91026a938c2
("drm/mediatek: hdmi: Add optional limit on maximal HDMI mode clock")
another similar check was introduced.

Unfortunately though, at the time of writing, MT8173 does not provide
any mtk_hdmi_conf structure and this is crashing the kernel with NULL
pointer upon entering mtk_hdmi_bridge_mode_valid(), which happens as
soon as a HDMI cable gets plugged in.

To fix this regression, add a NULL pointer check for hdmi->conf in the
said function, restoring HDMI functionality and avoiding NULL pointer
kernel panics.

Subject: drm/i915/uc: correctly track uc_fw init failure

The FAILURE state of uc_fw currently implies that the fw is loadable
(i.e init completed), so we can't use it for init failures and instead
need a dedicated error code.

Note that this currently does not cause any issues because if we fail to
init any of the firmwares we abort the load, but better be accurate
anyway in case things change in the future.

Subject: drm/i915/uc: Prepare for different firmware key sizes

Future GuC/HuC firmwares might be signed with different key sizes.
Don't assume that it must be always 2048 bits long.

Subject: drm/i915/guc: support bigger RSA keys

Some of the newer HW will use bigger RSA keys to authenticate the GuC
binary. On those platforms the HW will read the key from memory instead
of the RSA registers, so we need to copy it in a dedicated vma, like we
do for the HuC. The address of the key is provided to the HW via the
first RSA register.

v2: clarify that the RSA behavior is hardcoded in the bootrom (Matt)

Subject: drm/i915: Don't leak the capture list items
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When we recently converted the capture code to use vma snapshots,
we forgot to free the struct i915_capture_list list items after use.

Fix that by bringing back a kfree.

Fixes: ff20afc4cee7 ("drm/i915: Update error capture code to avoid using the current vma state")

Subject: drm/amdgpu: skip reset other device in the same hive if it's SRIOV VF

On SRIOV, host driver can support FLR(function level reset) on individual VF
within the hive which might bring the individual device back to normal without
the necessary to execute the hive reset. If the FLR failed , host driver will
trigger the hive reset, each guest VF will get reset notification before the
real hive reset been executed. The VF device can handle the reset request
individually in it's reset work handler.

This change updated gpu recover sequence to skip reset other device in
the same hive for SRIOV VF.

Subject: drm/amdkfd: Fix error handling in svm_range_add

Add null-pointer check after the last svm_range_new call. This was
originally reported by Zhou Qingyang <zhou1615@umn.edu> based on a
static analyzer.

To avoid duplicating the unwinding code from svm_range_handle_overlap,
I merged the two functions into one.

Subject: drm/amdkfd: Fix svm_range_is_same_attrs

The existing function doesn't compare the access bitmaps and flags.
This can result in failure to update those attributes in existing
ranges when all other attributes remained unchanged.

Because the access and flags attributes modify only some bits in the
respective bitmaps, we cannot compare them directly. Instead we need to
check whether applying the attributes to a particular range would
change the bitmaps.

A PREFETCH_LOC attribute must always trigger a migration, even if the
attribute value remains unchanged. E.g. if some pages were migrated due
to a CPU page fault, a prefetch must still be executed to migrate pages
back to VRAM.

Subject: drm/amdkfd: Don't split unchanged SVM ranges

If an existing SVM range overlaps an svm_range_set_attr call, we would
normally split it in order to update only the overlapping part.
However, if the attributes of the existing range would not be changed
splitting it is unnecessary.

vcn_config

Subject: drm/amdgpu: introduce a kind of halt state for amdgpu device

It is useful to maintain error context when debugging
SW/FW issues. Introduce amdgpu_device_halt() for this
purpose. It will bring hardware to a kind of halt state,
so that no one can touch it any more.

Compare to a simple hang, the system will keep stable
at least for SSH access. Then it should be trivial to
inspect the hardware state and see what's going on.

v2:
 - Set adev->no_hw_access earlier to avoid potential crashes.(Christian)

Subject: drm/amdgpu: add support for SMU debug option

SMU firmware expects the driver maintains error context
and doesn't interact with SMU any more when SMU errors
occurred. That will aid in debugging SMU firmware issues.

Add SMU debug option support for this request, it can be
enabled or disabled via amdgpu_smu_debug debugfs file.
Use a 32-bit mask to indicate corresponding debug modes.
Currently, only one mode(HALT_ON_ERROR) is supported.
When enabled, it brings hardware to a kind of halt state
so that no one can touch it any more in the envent of SMU
errors.

The dirver interacts with SMU via sending messages. And
threre are three ways to sending messages to SMU in current
implementation. Handle them respectively as following:

1, smu_cmn_send_smc_msg_with_param() for normal timeout cases

  Halt on any error.

2, smu_cmn_send_msg_without_waiting()/smu_cmn_wait_for_response()
for longer timeout cases

  Halt on errors apart from ETIME. Otherwise this way won't work.
  Let the user handle ETIME error in such a case.

3, smu_cmn_send_msg_without_waiting() for no waiting cases

  Halt on errors apart from ETIME. Otherwise second way won't work.

== Command Guide ==

1, enable HALT_ON_ERROR mode

 # echo 0x1 > /sys/kernel/debug/dri/0/amdgpu_smu_debug

2, disable HALT_ON_ERROR mode

 # echo 0x0 > /sys/kernel/debug/dri/0/amdgpu_smu_debug

v5:
 - Use bit mask to allow more debug features.(Evan)
 - Use WRAN() instead of BUG().(Evan)

v4:
 - Set to halt state instead of a simple hang.(Christian)

v3:
 - Use debugfs_create_bool().(Christian)
 - Put variable into smu_context struct.
 - Don't resend command when timeout.

v2:
 - Resend command when timeout.(Lijo)
 - Use debugfs file instead of module parameter.

Subject: drm/amdgpu: Detect if amdgpu in IOMMU direct map mode

If host and amdgpu IOMMU is not enabled or IOMMU is pass through mode,
set adev->ram_is_direct_mapped flag which will be used to optimize
memory usage for multi GPU mappings.

Subject: drm/amdgpu: Reduce SG bo memory usage for mGPUs

For userptr bo, if adev is not in IOMMU isolation mode, RAM direct map
to GPU, multiple GPUs use same system memory dma mapping address, they
can share the original mem->bo in attachment to reduce dma address array
memory usage.

Subject: drm/amd/display: Reduce stack size for
 dml31_ModeSupportAndSystemConfigurationFull
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move code using the Pipe struct to a new helper function.

Works around[0] this warning (resulting in failure to build a RHEL debug
kernel with Werror enabled):

../drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn31/display_mode_vba_31.c: In function ‘dml31_ModeSupportAndSystemConfigurationFull’:
../drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn31/display_mode_vba_31.c:5740:1: warning: the frame size of 2144 bytes is larger than 2048 bytes [-Wframe-larger-than=]

The culprit seems to be the Pipe struct, so pull the relevant block out
into its own sub-function. (This is porting
commit a62427ef9b55 ("drm/amd/display: Reduce stack size for dml21_ModeSupportAndSystemConfigurationFull")
from dml31 to dml21)

[0] AFAICT this doesn't actually reduce the total amount of stack which
can be used, just moves some of it from
dml31_ModeSupportAndSystemConfigurationFull to the new helper function,
so the former happens to no longer exceed the limit for a single
function.

Subject: drm/amd/display: Reduce stack size for dml31 UseMinimumDCFCLK
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use the struct display_mode_lib pointer instead of passing lots of large
arrays as parameters by value.

Addresses this warning (resulting in failure to build a RHEL debug kernel
with Werror enabled):

../drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn31/display_mode_vba_31.c: In function ‘UseMinimumDCFCLK’:
../drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn31/display_mode_vba_31.c:7478:1: warning: the frame size of 2128 bytes is larger than 2048 bytes [-Wframe-larger-than=]

NOTE: AFAICT this function previously had no observable effect, since it
only modified parameters passed by value and doesn't return anything.
Now it may modify some values in struct display_mode_lib passed in by
reference.

From 240e6d25a0a8ab98c042e37b2fd3c1f2cbf3e561 Mon Sep 17 00:00:00 2001
From: Isabella Basso <isabbasso@riseup.net>
Date: Wed, 8 Dec 2021 14:46:51 -0300
Subject: drm/amd/display: fix function scopes

This turns previously global functions into static, thus removing
compile-time warnings such as:

 warning: no previous prototype for 'get_highest_allowed_voltage_level'
 [-Wmissing-prototypes]
 742 | unsigned int get_highest_allowed_voltage_level(uint32_t chip_family, uint32_t hw_internal_rev, uint32_t pci_revision_id)
     |              ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 warning: no previous prototype for 'rv1_vbios_smu_send_msg_with_param'
 [-Wmissing-prototypes]
 102 | int rv1_vbios_smu_send_msg_with_param(struct clk_mgr_internal *clk_mgr, unsigned int msg_id, unsigned int param)
     |     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Changes since v1:
- As suggested by Rodrigo Siqueira:
  1. Rewrite function signatures to make them more readable.
  2. Get rid of unused functions in order to remove 'defined but not
     used' warnings.

Subject: drm/msm/a6xx: Skip crashdumper state if GPU needs_hw_init

I am seeing some crash logs which imply that we are trying to use
crashdumper hw to read back GPU state when the GPU isn't initialized.
This doesn't go well (for example, GPU could be in 32b address mode
and ignoring the upper bits of buffer that it is trying to dump state
to).

I'm not *quite* sure how we get into this state in the first place,
but lets not make a bad situation worse by triggering iova fault
crashes.

While we're at it, also add the information about whether the GPU is
initialized to the devcore dump to make this easier to see in the
logs (which makes the WARN_ON() redundant and even harmful because
it fills up the small bit of dmesg we get with the crash report).

Subject: drm/mediatek: Set the default value of rotation to DRM_MODE_ROTATE_0

At the reset hook, call __drm_atomic_helper_plane_reset which is
called at the initialization of the plane and sets the default value of
rotation on all planes to DRM_MODE_ROTATE_0 which is equal to 1.

Tested on Jacuzzi (MTK).

smatch warning:
drivers/gpu/drm/i915/display/intel_dmc.c:601 parse_dmc_fw() warn:
unsigned 'fw->size - offset' is never less than zero

Firmware size is size_t and offset is u32. So the subtraction is
unsigned which can never be less than zero.

Subject: drm/i915: Sanitycheck device iomem on probe

As we setup the memory regions for the device, give each a quick test to
verify that we can read and write to the full iomem range. This ensures
that our physical addressing for the device's memory is correct, and
some reassurance that the memory is functional.

v2: wrapper for memtest [Chris]

v3: Removed the unused ptr i915 [Chris]

v4: used the %pa for the resource_size_t.

Subject: drm/i915: Test all device memory on probing

This extends the previous sanitychecking of device memory to read/write
all the memory on the device during the device probe, ala memtest86,
as an optional module parameter: i915.memtest=1. This is not expected to
be fast, but a reasonably thorough verfification that the device memory
is accessible and doesn't return bit errors.

v2: Rebased.

ttm->num_pages is uint32_t which was causing very large buffers to
only populate a truncated size.

This fixes gem_create@create-clear igt test on large memory systems.

Subject: drm/i915/debugfs: add noreclaim annotations
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We have a debugfs hook to directly call into i915_gem_shrink() with the
fs_reclaim acquire annotations to simulate hitting direct reclaim.
However we should also annotate this with memalloc_noreclaim, which will
set PF_MEMALLOC for us on the current context, to ensure we can't
re-enter direct reclaim(just like "real" direct reclaim does). This is
an issue now that ttm_bo_validate could potentially be called here,
which might try to allocate a tiny amount of memory to hold the new
ttm_resource struct, as per the below splat:

Subject: drm/amd/display: Set exit_optimized_pwr_state for DCN31

[Why]
SMU now respects the PHY refclk disable request from driver.

This causes a hang during hotplug when PHY refclk was disabled
because it's not being re-enabled and the transmitter control
starts on dc_link_detect.

[How]
We normally would re-enable the clk with exit_optimized_pwr_state
but this is only set on DCN21 and DCN301. Set it for dcn31 as well.

This fixes DMCUB timeouts in the PHY.

[Why & How]
In order to know the intermediate link rates supported by the eDP
panel and test to select the optimized link rate to save power,
create a new debugfs entry "ilr_setting" for
setting ILR.

Subject: drm/amd/display: Force det buf size to 192KB with 3+ streams and
 upscaling

[WHY]
This workaround resolves underflow caused by incorrect DST_Y_PREFETCH.
Overriding to 192KB DET buf size until the DST_Y_PREFETCH calc is fixed.

Subject: drm/amd/display: Reset DMCUB before HW init

[Why]
If the firmware wasn't reset by PSP or HW and is currently running
then the firmware will hang or perform underfined behavior when we
modify its firmware state underneath it.

[How]
Reset DMCUB before setting up cache windows and performing HW init.

Subject: drm/amd/display: ODM + MPO window on only one half of ODM

[Why]
For ODM + MPO window on one half of ODM, only 3 pipes should
be allocated and scaling parameters adjusted to handle this case

[How]
Fix pipe allocation when MPO viewport is only on one side of ODM
split, and modify scaling paramters.
Added diags test cases for ODM + windows MPO, where MPO window is
on right half, left half, and both halves or ODM.

From 4866b0bfea40cddb7275c88aeb95b47dac3d2a35 Mon Sep 17 00:00:00 2001
From: Martin Leung <Martin.Leung@amd.com>
Date: Fri, 10 Dec 2021 15:04:07 -0800
Subject: drm/amd/display: implement dc_mode_memclk

why:
Need interface to lower clocks when in dc (power save)
mode. Must be able to work with p_state unsupported cases
Can cause flicker when OS notifies us of dc state change

how:
added dal3 interface for KMD
added pathway to query smu for this softmax
added blank before clock change to override underflow
added logic to change clk based on pstatesupport and softmax
added logic in prepare/optimize_bw to conform while changing
clocks

Subject: drm/amdgpu: move smu_debug_mask to a more proper place

As the smu_context will be invisible from outside(of power). Also,
the smu_debug_mask can be shared around all power code instead of
some specific framework(swSMU) only.

Subject: drm/amd/display: Set exit_optimized_pwr_state for DCN31

[Why]
SMU now respects the PHY refclk disable request from driver.

This causes a hang during hotplug when PHY refclk was disabled
because it's not being re-enabled and the transmitter control
starts on dc_link_detect.

[How]
We normally would re-enable the clk with exit_optimized_pwr_state
but this is only set on DCN21 and DCN301. Set it for dcn31 as well.

This fixes DMCUB timeouts in the PHY.

Subject: drm/vc4: kms: Wait for the commit before increasing our clock rate

Several DRM/KMS atomic commits can run in parallel if they affect
different CRTC. These commits share the global HVS state, so we have
some code to make sure we run commits in sequence. This synchronization
code is one of the first thing that runs in vc4_atomic_commit_tail().

Another constraints we have is that we need to make sure the HVS clock
gets a boost during the commit. That code relies on clk_set_min_rate and
will remove the old minimum and set a new one. We also need another,
temporary, minimum for the duration of the commit.

The algorithm is thus to set a temporary minimum, drop the previous
one, do the commit, and finally set the minimum for the current mode.

However, the part that sets the temporary minimum and drops the older
one runs before the commit synchronization code.

Thus, under the proper conditions, we can end up mixing up the minimums
and ending up with the wrong one for our current step.

To avoid it, let's move the clock setup in the protected section.

Subject: drm/msm/dpu: move disable_danger out of plane subdir

The disable_danger debugfs file is not related to a single plane.
Instead it is used by all registered planes. Move it from plane subtree
to the global subtree next to danger_status and safe_status files,
so that the new file supplements them.

Subject: drm/msm/dpu: stop manually removing debugfs files for the DPU CRTC

DRM code handles removing all debugfs recursively. Drop CRTC-specific
code to perform that.

Subject: drm/i915/guc: Don't hog IRQs when destroying contexts

While attempting to debug a CT deadlock issue in various CI failures
(most easily reproduced with gem_ctx_create/basic-files), I was seeing
CPU deadlock errors being reported. This were because the context
destroy loop was blocking waiting on H2G space from inside an IRQ
spinlock. There no was deadlock as such, it's just that the H2G queue
was full of context destroy commands and GuC was taking a long time to
process them. However, the kernel was seeing the large amount of time
spent inside the IRQ lock as a dead CPU. Various Bad Things(tm) would
then happen (heartbeat failures, CT deadlock errors, outstanding H2G
WARNs, etc.).

Re-working the loop to only acquire the spinlock around the list
management (which is all it is meant to protect) rather than the
entire destroy operation seems to fix all the above issues.

Subject: drm/i915/guc: Selftest for stealing of guc ids

Testing the stealing of guc ids is hard from user space as we have 64k
guc_ids. Add a selftest, which artificially reduces the number of guc
ids, and forces a steal.

The test creates a spinner which is used to block all subsequent
submissions until it completes. Next, a loop creates a context and a NOP
request each iteration until the guc_ids are exhausted (request creation
returns -EAGAIN). The spinner is ended, unblocking all requests created
in the loop. At this point all guc_ids are exhausted but are available
to steal. Try to create another request which should successfully steal
a guc_id. Wait on last request to complete, idle GPU, verify a guc_id
was stolen via a counter, and exit the test. Test also artificially
reduces the number of guc_ids so the test runs in a timely manner.

v2:
 (John Harrison)
  - s/stole/stolen
  - Fix some wording in test description

Subject: drm/bridge: lvds-codec: Add support for pixel data sampling edge
 select

The OnSemi FIN3385 Parallel-to-LVDS encoder has a dedicated input line to
select input pixel data sampling edge. Add DT property "pclk-sample", not
the same as the one used by display timings but rather the same as used by
media, and configure bus flags based on this DT property.

Add XRGB8888 emulation support for devices that can only do XRGB2101010.

This is chiefly useful for simpledrm on Apple devices where the
bootloader-provided framebuffer is 10-bit.

Subject: drm/vc4: plane: Add support for YUV color encodings and ranges

The BT601/BT709 color encoding and limited vs full
range properties were not being exposed, defaulting
always to BT601 limited range.

Expose the parameters and set the registers appropriately.

Subject: drm/ast: Handle failed I2C initialization gracefully

I2C initialization is allowed to fail. In this case, create a connector
without DDC adapter. The current code would dereference a NULL pointer.

Reading the modes from the connector is supposed to work without I2C
adapter. Add the respective test.

v2:
	* init edid to NULL to avoid uninitialized read (Dan)

Subject: drm/tegra: Implement correct DMA-BUF semantics

DMA-BUF requires that each device that accesses a DMA-BUF attaches to it
separately. To do so the host1x_bo_pin() and host1x_bo_unpin() functions
need to be reimplemented so that they can return a mapping, which either
represents an attachment or a map of the driver's own GEM object.

From 1f39b1dfa53c84b56d7ad37fed44afda7004959d Mon Sep 17 00:00:00 2001
From: Thierry Reding <treding@nvidia.com>
Date: Fri, 7 Feb 2020 16:50:52 +0100
Subject: drm/tegra: Implement buffer object cache

This cache is used to avoid mapping and unmapping buffer objects
unnecessarily. Mappings are cached per client and stay hot until
the buffer object is destroyed.

Subject: drm/tegra: Do not reference tegra_plane_funcs directly

Instead of referencing the tegra_plane_funcs struct directly, use each
plane's vtable instead. This makes it more future-proof in case any of
the planes ever use a different set of functions.

Subject: drm/tegra: dc: rgb: Move PCLK shifter programming to CRTC

Asus TF700T tablet uses TC358768 DPI->DSI bridge that sits between Tegra's
DPI output and display panel input. Bridge requires to have stable PCLK
output before RGB encoder is enabled because it uses PCLK by itself to
clock internal logic and bridge is programmed before Tegra's encoder is
enabled. Hence the PCLK clock shifter must be programmed when CRTC is
enabled, otherwise clock is unstable and bridge hangs because of it.
Move the shifter programming from RGB encoder into CRTC.

Subject: drm/tegra: gr2d: Explicitly control module reset

As of commit 4782c0a5dd88 ("clk: tegra: Don't deassert reset on enabling
clocks"), module resets are no longer automatically deasserted when the
module clock is enabled. To make sure that the gr2d module continues to
work, we need to explicitly control the module reset.

Fixes: 4782c0a5dd88 ("clk: tegra: Don't deassert reset on enabling clocks")

Subject: drm/tegra: dc: rgb: Allow changing PLLD rate on Tegra30+

Asus Transformer TF700T is a Tegra30 tablet device which uses RGB->DSI
bridge that requires a precise clock rate in order to operate properly.
Tegra30 has a dedicated PLL for each display controller, hence the PLL
rate can be changed freely. Allow PLL rate changes on Tegra30+ for RGB
output. Configure the clock rate before display controller is enabled
since DC itself may be running off this PLL and it's not okay to change
the rate of the active PLL that doesn't support dynamic frequency
switching since hardware will hang.

Subject: drm/tegra: Mark nvdec_writel() as inline

Without CONFIG_IOMMU_API, the nvdec_writel() function is unused, causing
a warning:

drivers/gpu/drm/tegra/nvdec.c:48:13: error: 'nvdec_writel' defined but not used [-Werror=unused-function]
   48 | static void nvdec_writel(struct nvdec *nvdec, u32 value, unsigned int offset)
      |             ^~~~~~~~~~~~

As this is a trivial wrapper around an inline function, mark it as
inline itself, which avoids the warning as well.

Subject: drm/tegra: vic: Fix DMA API misuse

Upon failure, dma_alloc_coherent() returns NULL. If that does happen,
passing some uninitialised stack contents to dma_mapping_error() - which
belongs to a different API in the first place - has precious little
chance of detecting it.

Also include the correct header, because the fragile transitive
inclusion currently providing it is going to break soon.

Subject: drm/tegra: hdmi: Add OPP support

The HDMI on Tegra belongs to the core power domain and we're going to
enable GENPD support for the core domain. Now HDMI driver must use
OPP API for driving the controller's clock rate because OPP API takes
care of reconfiguring the domain's performance state based on HDMI clock
rate. Add OPP support to the HDMI driver.

Subject: drm/tegra: vic: Stop channel on suspend

CDMA must be stopped before hardware is suspended. Add channel stopping
to RPM suspend callback. Add system level suspend-resume callbacks.

Runtime PM initialization is moved to host1x client init phase because
RPM callback now uses host1x channel that is available only when host1x
client is registered.

Subject: drm/tegra: Add back arm_iommu_detach_device()

DMA buffers of 2D/3D engines aren't mapped properly when
CONFIG_ARM_DMA_USE_IOMMU=y. The memory management code of Tegra DRM driver
has a longstanding overhaul overdue and it's not obvious where the problem
is in this case. Hence let's add back the old workaround which we already
had sometime before. It explicitly detaches DRM devices from the offending
implicit IOMMU domain. This fixes a completely broken 2d/3d drivers in
case of ARM32 multiplatform kernel config.

Cc: stable@vger.kernel.org
Fixes: fa6661b7aa0b ("drm/tegra: Optionally attach clients to the IOMMU")

In the s0ix entry need retain gfx in the gfxoff state,so here need't
set gfx cgpg in the S0ix suspend-resume process. Moreover move the S0ix
check into SMU12 can simplify the code condition check.

Subject: drm/amdgpu: introduce new amdgpu_fence object to indicate the job
 embedded fence
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The job embedded fence donesn't initialize the flags at
dma_fence_init(). Then we will go a wrong way in
amdgpu_fence_get_timeline_name callback and trigger a null pointer panic
once we enabled the trace event here. So introduce new amdgpu_fence
object to indicate the job embedded fence.

Subject: drm/amdkfd: fix svm_bo release invalid wait context warning

Add svm_range_bo_unref_async to schedule work to wait for svm_bo
eviction work done and then free svm_bo. __do_munmap put_page
is atomic context, call svm_range_bo_unref_async to avoid warning
invalid wait context. Other non atomic context call svm_range_bo_unref.

Subject: drm/amdgpu: When the VCN(1.0) block is suspended, powergating is
 explicitly enabled

Play a video on the raven (or PCO, raven2) platform, and then do the S3
test. When resume, the following error will be reported:

amdgpu 0000:02:00.0: [drm:amdgpu_ring_test_helper [amdgpu]] *ERROR* ring
vcn_dec test failed (-110)
[drm:amdgpu_device_ip_resume_phase2 [amdgpu]] *ERROR* resume of IP block
<vcn_v1_0> failed -110
amdgpu 0000:02:00.0: amdgpu: amdgpu_device_ip_resume failed (-110).
PM: dpm_run_callback(): pci_pm_resume+0x0/0x90 returns -110

[why]
When playing the video: The power state flag of the vcn block is set to
POWER_STATE_ON.

When doing suspend: There is no change to the power state flag of the
vcn block, it is still POWER_STATE_ON.

When doing resume: Need to open the power gate of the vcn block and set
the power state flag of the VCN block to POWER_STATE_ON.
But at this time, the power state flag of the vcn block is already
POWER_STATE_ON. The power status flag check in the "8f2cdef drm/amd/pm:
avoid duplicate powergate/ungate setting" patch will return the
amdgpu_dpm_set_powergating_by_smu function directly.
As a result, the gate of the power was not opened, causing the
subsequent ring test to fail.

[how]
In the suspend function of the vcn block, explicitly change the power
state flag of the vcn block to POWER_STATE_OFF.

Subject: drm/amdgpu: Separate vf2pf work item init from virt data exchange

We want to be able to call virt data exchange conditionally
after gmc sw init to reserve bad pages as early as possible.
Since this is a conditional call, we will need
to call it again unconditionally later in the init sequence.

Refactor the data exchange function so it can be
called multiple times without re-initializing the work item.

v2: Cleaned up the code. Kept the original call to init_exchange_data()
inside early init to initialize the work item, afterwards call
exchange_data() when needed.

Subject: dmaengine: xilinx_dpdma: stop using slave_id field

The display driver wants to pass a custom flag to the DMA engine driver,
which it started doing by using the slave_id field that was traditionally
used for a different purpose.

As there is no longer a correct use for the slave_id field, it should
really be removed, and the remaining users changed over to something
different.

The new mechanism for passing nonstandard settings is using the
.peripheral_config field, so use that to pass a newly defined structure
here, making it clear that this will not work in portable drivers.

Subject: drm/vmwgfx: Fix a size_t/long int format specifier mismatch

On i386 size_t is of course 32bits and using long int throws warnings,
trivially fix it by using the dedicated size_t format.

This is enough to fix the following warning found by the kernel test

Subject: drm/vmwgfx: Remove explicit transparent hugepages support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Old versions of the svga device used to export virtual vram, handling of
which was optimized on top of transparent hugepages support. Only very
old devices (OpenGL 2.1 support and earlier) used this code and at this
point performance differences are negligible.

Because the code requires very old hardware versions to run it has
been largely untested and unused for a long time.

Furthermore removal of the ttm hugepages support in:
commit 0d979509539e ("drm/ttm: remove ttm_bo_vm_insert_huge()")
broke the coherency mode in vmwgfx when running with hugepages.

Subject: drm/vmwgfx: Remove unused compile options

Before the driver had screen targets support we had to disable explicit
bringup of its infrastructure because it was breaking screen objects
support.
Since the implementation of screen targets landed there hasn't been a
reason to explicitly disable it and the options were never used.
Remove of all that unused code.

Subject: drm/vmwgfx: Fix possible usage of an uninitialized variable

vmw_user_bo_lookup can fail to lookup user buffers, especially because
the buffer handles come from the userspace. The return value has
to be checked before the buffers are put back.

This was spotted by Dan's Smatch statick checker:
    drivers/gpu/drm/vmwgfx/vmwgfx_bo.c:574 vmw_user_bo_synccpu_release()
	error: uninitialized symbol 'vmw_bo'.

Subject: drm/amdgpu: introduce new amdgpu_fence object to indicate the job
 embedded fence
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The job embedded fence donesn't initialize the flags at
dma_fence_init(). Then we will go a wrong way in
amdgpu_fence_get_timeline_name callback and trigger a null pointer panic
once we enabled the trace event here. So introduce new amdgpu_fence
object to indicate the job embedded fence.

Subject: drm/amdgpu: When the VCN(1.0) block is suspended, powergating is
 explicitly enabled

Play a video on the raven (or PCO, raven2) platform, and then do the S3
test. When resume, the following error will be reported:

amdgpu 0000:02:00.0: [drm:amdgpu_ring_test_helper [amdgpu]] *ERROR* ring
vcn_dec test failed (-110)
[drm:amdgpu_device_ip_resume_phase2 [amdgpu]] *ERROR* resume of IP block
<vcn_v1_0> failed -110
amdgpu 0000:02:00.0: amdgpu: amdgpu_device_ip_resume failed (-110).
PM: dpm_run_callback(): pci_pm_resume+0x0/0x90 returns -110

[why]
When playing the video: The power state flag of the vcn block is set to
POWER_STATE_ON.

When doing suspend: There is no change to the power state flag of the
vcn block, it is still POWER_STATE_ON.

When doing resume: Need to open the power gate of the vcn block and set
the power state flag of the VCN block to POWER_STATE_ON.
But at this time, the power state flag of the vcn block is already
POWER_STATE_ON. The power status flag check in the "8f2cdef drm/amd/pm:
avoid duplicate powergate/ungate setting" patch will return the
amdgpu_dpm_set_powergating_by_smu function directly.
As a result, the gate of the power was not opened, causing the
subsequent ring test to fail.

[how]
In the suspend function of the vcn block, explicitly change the power
state flag of the vcn block to POWER_STATE_OFF.

Subject: drm/msm/a5xx: Fix missing CP_PROTECT for SMMU on A540

A CP_PROTECT entry for SMMU registers is missing for A540. According to
downstream sources its length is same as on A530 - 0x20000 bytes.

On all other revisions SMMU region length is 0x10000 bytes. Despite
this, we setup region of length 0x20000 on all revisions. This doesn't
cause any issues on those GPUs. As for preventing accesses to the region
from protected mode it was tested to work the same.

This patch drops the "if" condition in setup of CP_PROTECT entry because
it already includes all supported revisions except A540.

Subject: drm/i915: Store backpointer to GT in uncore
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We now support a per-gt uncore, yet we're not able to infer which GT
we're operating upon.  Let's store a backpointer for now.

At this point the early initialization of the gt needs to be
broken in two parts where the first is needed to assign to the gt
the i915 private data pointer and the uncore. A temporary
function has been made and the two parts are
__intel_gt_init_early() and intel_gt_init_early(). This split
will be fixed in the future with the multitile patch.

Subject: drm/i915/gt: Use to_gt() helper
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use to_gt() helper consistently throughout the codebase.
Pure mechanical s/i915->gt/to_gt(i915). No functional changes.

Subject: drm/i915/gem: Use to_gt() helper
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use to_gt() helper consistently throughout the codebase.
Pure mechanical s/i915->gt/to_gt(i915). No functional changes.

Subject: drm/i915: Change shrink ordering to use locking around unbinding.

Call drop_pages with the gem object lock held, instead of the other
way around. This will allow us to drop the vma bindings with the
gem object lock held.

We plan to require the object lock for unpinning in the future,
and this is an easy target.

Subject: drm/i915: Remove pages_mutex and intel_gtt->vma_ops.set/clear_pages
 members, v3.

Big delta, but boils down to moving set_pages to i915_vma.c, and removing
the special handling, all callers use the defaults anyway. We only remap
in ggtt, so default case will fall through.

Because we still don't require locking in i915_vma_unpin(), handle this by
using xchg in get_pages(), as it's locked with obj->mutex, and cmpxchg in
unpin, which only fails if we race a against a new pin.

Changes since v1:
- aliasing gtt sets ZERO_SIZE_PTR, not -ENODEV, remove special case
  from __i915_vma_get_pages(). (Matt)
Changes since v2:
- Free correct old pages in __i915_vma_get_pages(). (Matt)
  Remove race of clearing vma->pages accidentally from put,
  free it but leave it set, as only get has the lock.

Subject: drm/i915: Force ww lock for i915_gem_object_ggtt_pin_ww, v2.

We will need the lock to unbind the vma, and wait for bind to complete.
Remove the special casing for the !ww path, and force ww locking for all.

Changes since v1:
- Pass err to for_i915_gem_ww handling for -EDEADLK handling.

Subject: drm/i915: Ensure gem_contexts selftests work with unbind changes, v2.

In the next commits, we may not evict when refcount = 0.

igt_vm_isolation() continuously tries to pin/unpin at same address,
but also calls put() on the object, which means the object may not
be unpinned in time.

Instead of this, re-use the same object over and over, so they can
be unbound as required.

Changes since v1:
- Fix cleaning up obj_b on failure. (Matt)

Subject: drm/i915: Ensure i915_vma tests do not get -ENOSPC with the locking
 changes.

Now that we require locking to evict, multiple vmas from the same object
might not be evicted. This is expected and required, because execbuf will
move to short-term pinning by using the lock only. This will cause these
tests to fail, because they create a ton of vma's for the same object.

Unbind manually to prevent spurious -ENOSPC in those mock tests.

Subject: drm/etnaviv: limit submit sizes

Currently we allow rediculous amounts of kernel memory being allocated
via the etnaviv GEM_SUBMIT ioctl, which is a pretty easy DoS vector. Put
some reasonable limits in to fix this.

The commandstream size is limited to 64KB, which was already a soft limit
on older kernels after which the kernel only took submits on a best effort
base, so there is no userspace that tries to submit commandstreams larger
than this. Even if the whole commandstream is a single incrementing address
load, the size limit also limits the number of potential relocs and
referenced buffers to slightly under 64K, so use the same limit for those
arguments. The performance monitoring infrastructure currently supports
less than 50 performance counter signals, so limiting them to 128 on a
single submit seems like a reasonably future-proof number for now. This
number can be bumped if needed without breaking the interface.

Subject: drm/i915/guc: Speed up GuC log dumps

Add support for telling the debugfs interface the size of the GuC log
dump in advance. Without that, the underlying framework keeps calling
the 'show' function with larger and larger buffer allocations until it
fits. That means reading the log from graphics memory many times - 16
times with the full 18MB log size.

v2: Don't return error codes from size query. Report overflow in the
error dump as well (review feedback from Daniele).

Subject: drm/i915/guc: Increase GuC log size for CONFIG_DEBUG_GEM

Lots of testing is done with the DEBUG_GEM config option enabled but
not the DEBUG_GUC option. That means we only get teeny-tiny GuC logs
which are not hugely useful. Enabling full DEBUG_GUC also spews lots
of other detailed output that is not generally desired. However,
bigger GuC logs are extremely useful for almost any regression debug.
So enable bigger logs for DEBUG_GEM builds as well.

Subject: drm/i915/guc: Flag an error if an engine reset fails

If GuC encounters an error during engine reset, the i915 driver
promotes to full GT reset. This includes an info message about why the
reset is happening. However, that is not treated as a failure by any
of the CI systems because resets are an expected occurrance during
testing. This kind of failure is a major problem and should never
happen. So, complain more loudly and make sure CI notices.

Always waiting for the exclusive fence resulted on some performance

exclusive fence should always be signaled already.

Subject: drm/i915/guc: Request RP0 before loading firmware

By default, GT (and GuC) run at RPn. Requesting for RP0
before firmware load can speed up DMA and HuC auth as well.
In addition to writing to 0xA008, we also need to enable
swreq in 0xA024 so that Punit will pay heed to our request.

SLPC will restore the frequency back to RPn after initialization,
but we need to manually do that for the non-SLPC path.

We don't need a manual override in the SLPC disabled case, just
use the intel_rps_set function to ensure consistent RPS state.

Subject: drm/exynos: Replace legacy gpio interface for gpiod interface
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Considering the current transition of the GPIO subsystem, remove all
dependencies of the legacy GPIO interface (linux/gpio.h and linux
/of_gpio.h) and replace it with the descriptor-based GPIO approach.

Subject: drm/exynos: Implement mmap as GEM object function

Moving the driver-specific mmap code into a GEM object function allows
for using DRM helpers for various mmap callbacks.

The respective exynos functions are being removed. The file_operations
structure exynos_drm_driver_fops is now being created by the helper macro
DEFINE_DRM_GEM_FOPS().

Subject: drm/exynos: drop the use of label from exynos_dsi_register_te_irq

Dropped the use of 'out' label from exynos_dsi_register_te_irq function
because the label isn't needed. This patch returns an error in each
error case directly not going to 'out' label.

With this patch build warning[1] is also fixed, which was reported by
kernel test robot <lkp@intel.com>

Subject: drm/i915: Avoid using the i915_fence_array when collecting
 dependencies
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since the gt migration code was using only a single fence for
dependencies, these were collected in a dma_fence_array. However, it
turns out that it's illegal to use some dma_fences in a dma_fence_array,
in particular other dma_fence_arrays and dma_fence_chains, and this
causes trouble for us moving forward.

Have the gt migration code instead take a const struct i915_deps for
dependencies. This means we can skip the dma_fence_array creation
and instead pass the struct i915_deps instead to circumvent the
problem.

v2:
- Make the prev_deps() function static. (kernel test robot <lkp@intel.com>)
- Update the struct i915_deps kerneldoc.
v4:
- Rebase.

Subject: drm/i915: remove questionable fence optimization during copy
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

First of all as discussed multiple times now kernel copies *must* always
wait for all fences in a BO before actually doing the copy. This is
mandatory.

Additional to that drop the handling when there can't be a shared slot
allocated on the source BO and just properly return an error code.
Otherwise this code path would only be tested under out of memory
conditions.

Since it's starting to be used outside the i915 TTM move code, move it
to a separate set of files.

v2:
- Update the documentation.
v4:
- Rebase.

Subject: drm/i915: Require the vm mutex for i915_vma_bind()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Protect updates of struct i915_vma flags and async binding / unbinding
with the vm::mutex. This means that i915_vma_bind() needs to assert
vm::mutex held. In order to make that possible drop the caching of
kmap_atomic() maps around i915_vma_bind().

An alternative would be to use kmap_local() but since we block cpu
unplugging during sleeps inside kmap_local() sections this may have
unwanted side-effects. Particularly since we might wait for gpu while
holding the vm mutex.

This change may theoretically increase execbuf cpu-usage on snb, but
at least on non-highmem systems that increase should be very small.

Subject: x86/MCE/AMD, EDAC/mce_amd: Support non-uniform MCA bank type
 enumeration

AMD systems currently lay out MCA bank types such that the type of bank
number "i" is either the same across all CPUs or is Reserved/Read-as-Zero.

For example:

  Bank # | CPUx | CPUy
    0      LS     LS
    1      RAZ    UMC
    2      CS     CS
    3      SMU    RAZ

Future AMD systems will lay out MCA bank types such that the type of
bank number "i" may be different across CPUs.

For example:

  Bank # | CPUx | CPUy
    0      LS     LS
    1      RAZ    UMC
    2      CS     NBIO
    3      SMU    RAZ

Change the structures that cache MCA bank types to be per-CPU and update
smca_get_bank_type() to handle this change.

Move some SMCA-specific structures to amd.c from mce.h, since they no
longer need to be global.

Break out the "count" for bank types from struct smca_hwid, since this
should provide a per-CPU count rather than a system-wide count.

Apply the "const" qualifier to the struct smca_hwid_mcatypes array. The
values in this array should not change at runtime.

Subject: drm/amdgpu: fix runpm documentation

It's not only supported by HG/PX laptops.  It's supported
by all dGPUs which supports BOCO/BACO functionality (runtime
D3).

BOCO - Bus Off, Chip Off.  The entire chip is powered off.
       This is controlled by ACPI.
BACO - Bus Active, Chip Off.  The chip still shows up
       on the PCI bus, but the device itself is powered
       down.

v2: fix missed HG/PX reference

Subject: drm/i915: Use trylock instead of blocking lock for
 __i915_gem_free_objects.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Convert free_work into delayed_work, similar to ttm to allow converting the
blocking lock in __i915_gem_free_objects to a trylock.

Unlike ttm, the object should already be idle, as it's kept alive
by a reference through struct i915_vma->active, which is dropped
after all vma's are idle.

Because of this, we can use a no wait by default, or when the lock
is contested, we use ttm's 10 ms.

The trylock should only fail when the object is sharing it's resv with
other objects, and typically objects are not kept locked for a long
time, so we can safely retry on failure.

Subject: drm/etnaviv: consider completed fence seqno in hang check

Some GPU heavy test programs manage to trigger the hangcheck quite often.
If there are no other GPU users in the system and the test program
exhibits a very regular structure in the commandstreams that are being
submitted, we can end up with two distinct submits managing to trigger
the hangcheck with the FE in a very similar address range. This leads
the hangcheck to believe that the GPU is stuck, while in reality the GPU
is already busy working on a different job. To avoid those spurious
GPU resets, also remember and consider the last completed fence seqno
in the hang check.

We mustn't forget to update our FBC state even if we don't have
to reallocate the CFB. Otherwise we won't refresh our notion
of what eg. the new fence or the new override CFB stride
should be. Using the wrong CFB stride in particular can cause
underruns and could even corrupt other stuff in stolen.

Subject: drm/amdgpu: always reset the asic in suspend (v2)

If the platform suspend happens to fail and the power rail
is not turned off, the GPU will be in an unknown state on
resume, so reset the asic so that it will be in a known
good state on resume even if the platform suspend failed.

v2: handle s0ix

Subject: drm/amdgpu: put SMU into proper state on runpm suspending for BOCO
 capable platform

By setting mp1_state as PP_MP1_STATE_UNLOAD, MP1 will do some proper cleanups and
put itself into a state ready for PNP. That can workaround some random resuming
failure observed on BOCO capable platforms.

Subject: drm/amdkfd: reset queue which consumes RAS poison (v2)

CP supports unmap queue with reset mode which only destroys specific queue without affecting others.
Replacing whole gpu reset with reset queue mode for RAS poison consumption
saves much time, and we can also fallback to gpu reset solution if reset
queue fails.

v2: Return directly if process is NULL;
    Reset queue solution is not applicable to SDMA, fallback to legacy
way;
    Call kfd_unref_process after lookup process.

Subject: drm/amdgpu: Don't inherit GEM object VMAs in child process
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When an application having open file access to a node forks, its shared
mappings also get reflected in the address space of child process even
though it cannot access them with the object permissions applied. With the
existing permission checks on the gem objects, it might be reasonable to
also create the VMAs with VM_DONTCOPY flag so a user space application
doesn't need to explicitly call the madvise(addr, len, MADV_DONTFORK)
system call to prevent the pages in the mapped range to appear in the
address space of the child process. It also prevents the memory leaks
due to additional reference counts on the mapped BOs in the child
process that prevented freeing the memory in the parent for which we had
worked around earlier in the user space inside the thunk library.

Additionally, we faced this issue when using CRIU to checkpoint restore
an application that had such inherited mappings in the child which
confuse CRIU when it mmaps on restore. Having this flag set for the
render node VMAs helps. VMAs mapped via KFD already take care of this so
this is needed only for the render nodes.

To limit the impact of the change to user space consumers such as OpenGL
etc, limit it to KFD BOs only.

Subject: drm/amdgpu: Send Message to SMU on aldebaran passthrough for sbr
 handling

For Aldebaran chip passthrough case we need to intimate SMU
about special handling for SBR.On older chips we send
LightSBR to SMU, enabling the same for Aldebaran. Slight
difference, compared to previous chips, is on Aldebaran, SMU
would do a heavy reset on SBR. Hence, the word Heavy
instead of Light SBR is used for SMU to differentiate.

Subject: drm/amd/display: Fix USB4 null pointer dereference in
 update_psp_stream_config

[Why]
A porting error on a previous patch left the block of code that
causes the crash from a NULL pointer dereference.

More specifically, we try to access link_enc before it's assigned in
the USB4 case in the following assignment:

config.dio_output_idx = link_enc->transmitter - TRANSMITTER_UNIPHY_A;

[How]
That assignment occurs later depending on the ASIC version. It's only
needed on DCN31 and only after link_enc is already assigned.

Fixes: 986430446c917b ("drm/amd/display: fix a crash on USB4 over C20 PHY")

Some boards(like RX550) seem to have garbage in the upper
16 bits of the vram size register.  Check for
this and clamp the size properly.  Fixes
boards reporting bogus amounts of vram.

after add this patch,the maximum GPU VRAM size is 64GB,
otherwise only 64GB vram size will be used.

[why]
B0 PHY C map to F, D map to G driver use logic instance, dmub does the
remap. Driver still need use the right PHY instance to access right HW.

[how]
use phyical instance when program PHY register.

[note]
could move resync_control programming to dmub next.

[Why]
The change of setting a timer callback on boot for 10 seconds is still
working, just lacked power down for DCN10.

[How]
Added power down for DCN10.

Subject: drm/amd/display: Send s0i2_rdy in stream_count == 0 optimization

[Why]
Otherwise SMU won't mark Display as idle when trying to perform s2idle.

[How]
Mark the bit in the dcn31 codepath, doesn't apply to older ASIC.

It needed to be split from phy refclk off to prevent entering s2idle
when PSR was engaged but driver was not ready.

Subject: drm/amd/display: Set optimize_pwr_state for DCN31

[Why]
We'll exit optimized power state to do link detection but we won't enter
back into the optimized power state.

This could potentially block s2idle entry depending on the sequencing,
but it also means we're losing some power during the transition period.

[How]
Hook up the handler like DCN21. It was also missed like the
exit_optimized_pwr_state callback.

Subject: drm/amd/display: Fix USB4 null pointer dereference in
 update_psp_stream_config

[Why]
A porting error on a previous patch left the block of code that
causes the crash from a NULL pointer dereference.

More specifically, we try to access link_enc before it's assigned in
the USB4 case in the following assignment:

config.dio_output_idx = link_enc->transmitter - TRANSMITTER_UNIPHY_A;

[How]
That assignment occurs later depending on the ASIC version. It's only
needed on DCN31 and only after link_enc is already assigned.

Subject: drm/amd/display: Changed pipe split policy to allow for multi-display
 pipe split

[WHY]
Current implementation of pipe split policy prevents pipe split with
multiple displays connected, which caused the MCLK speed to be stuck at
max

[HOW]
Changed the pipe split policies so that pipe split is allowed for
multi-display configurations

Subject: drm/amdgpu: Call amdgpu_device_unmap_mmio() if device is unplugged to
 prevent crash in GPU initialization failure
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

[Why]
In amdgpu_driver_load_kms, when amdgpu_device_init returns error during driver modprobe, it
will start the error handle path immediately and call into amdgpu_device_unmap_mmio as well
to release mapped VRAM. However, in the following release callback, driver stills visits the
unmapped memory like vcn.inst[i].fw_shared_cpu_addr in vcn_v3_0_sw_fini. So a kernel crash occurs.

[How]
call amdgpu_device_unmap_mmio() if device is unplugged to prevent invalid memory address in
vcn_v3_0_sw_fini() when GPU initialization failure.

Subject: drm/amdkfd: correct sdma queue number in kfd device init (v3)

This patch keeps the setting of sdma queue number to the same
after recent KFD code refactor. Additionally, improve code to
use switch case to list IP version to complete kfd device_info
structure filling for IH version assignment. This makes consistency
with the IP parse code in amdgpu_discovery.c.

v2: use dev_warn for the default switch case;
    set default sdma queue per engine(8) and IH handler to v9. (Jonathan)

v3: Fix missed IP version check of Raven.

Subject: drm/amdgpu: Check the memory can be accesssed by
 ttm_device_clear_dma_mappings.

If the event guard is enabled and VF doesn't receive an ack from PF for full access,
the guest driver load crashes.
This is caused due to the call to ttm_device_clear_dma_mappings with non-initialized
mman during driver tear down.

This patch adds the necessary condition to check if the mman initialization passed or not
and takes the path based on the condition output.

Subject: drm/amd/display: fix B0 TMDS deepcolor no dislay issue

[why]
B0 PHY C map to F, D map to G driver use logic instance, dmub does the
remap. Driver still need use the right PHY instance to access right HW.

[how]
use phyical instance when program PHY register.

[note]
could move resync_control programming to dmub next.

Subject: drm/amd/display: Limit max link cap with LTTPR caps

[Why]
Max link rate should be limited to the maximum link rate support by any
LTTPR that are connected, including when operating in transparent mode.

[How]
Include transparent mode when factoring in LTTPR max supported link
rate.

Subject: drm/amd/display: Refactor vendor specific link training sequence

[Why]
Current implementation is not scalable and retrofits the existing
standard link training code for purposes outside of its original design.

[How]
Refactor vendor specific link training sequence into its own separate
function to be called instead of the standard link training function.

Subject: drm/amd/display: Block z-states when stutter period exceeds criteria

[Why]
Stutter period won't be less than 5000.0, but if PSR is enabled then we
can potentially enter Z9 when MPO is enabled.

SMU will try to enter Z9 too early in these cases (before PSR is
enabled) and we'll see underflow.

[How]
Block z-states (z9, z10) until we can add a new interface to SMU to
signal when we can support z10 but not z9.

We can revert this once the interface change is in.

[Why]
Otherwise SMU won't mark Display as idle when trying to perform s2idle.

[How]
Mark the bit in the dcn31 codepath, doesn't apply to older ASIC.

It needed to be split from phy refclk off to prevent entering s2idle
when PSR was engaged but driver was not ready.

Subject: drm/amd/display: Remove CR AUX RD Interval limit for LTTPR

[Why]
DP spec specifies that DPRX shall use the read interval in the
TRAINING_AUX_RD_INTERVAL_PHY_REPEATER LTTPR DPCD register. This
register's bit definition is the same as the AUX read interval register
for DPRX.

[How}
Remove logic which forces AUX read interval to 100us for repeaters when
in LTTPR non-transparent mode.

Subject: drm/amd/display: Set optimize_pwr_state for DCN31

[Why]
We'll exit optimized power state to do link detection but we won't enter
back into the optimized power state.

This could potentially block s2idle entry depending on the sequencing,
but it also means we're losing some power during the transition period.

[How]
Hook up the handler like DCN21. It was also missed like the
exit_optimized_pwr_state callback.

From: Wenjing Liu <wenjing.liu@amd.com>
Date: Thu, 25 Nov 2021 12:30:50 -0500
Subject: drm/amd/display: define link res and make it accessible to all link
 interfaces

[why]
There will be a series of re-arch changes in Link Resource Management.
They are more and more muxable link resource objects and the resource is
insufficient for a one to one allocation to all links created.
Therefore a link resource sharing logic is required to determine which
link should use certain link resource.

This commit is the first one in this series that starts by defining a
link resource struct, this struct will be available to all interfaces
that need to perform link programming sequence.

In later commits, we will granduately decouple link resource objects out
of dc link. So instead of access a link resource from dc link. Current
link's resource can be accessible through pipe_ctx->link_res during
commit, or by calling  dc_link_get_cur_link_res function with current
link passed in after commit.

Subject: drm/amd/display: support dynamic HPO DP link encoder allocation

[why]
When there are more DP2.0 RXs connected than the number HPO DP link
encoders we have, we need to dynamically allocate HPO DP link encoder to
the port that needs it.

[how]
Only allocate HPO DP link encoder when it is needed.

Subject: drm/amd/display: get and restore link res map

[why]
When reboot the link res map should be persisted.  So during boot up,
driver will look at the map to determine which link should take priority
to use certain link res.  This is to ensure that link res remains
unshuffled after a reboot.

Subject: amdgpu/pm: Make sysfs pm attributes as read-only for VFs

== Description ==
Setting values of pm attributes through sysfs
should not be allowed in SRIOV mode.
These calls will not be processed by FW anyway,
but error handling on sysfs level should be improved.

== Changes ==
This patch prohibits performing of all set commands
in SRIOV mode on sysfs level.
It offers better error handling as calls that are
not allowed will not be propagated further.

== Test ==
Writing to any sysfs file in passthrough mode will succeed.
Writing to any sysfs file in ONEVF mode will yield error:
"calling process does not have sufficient permission to execute a command".

Subject: drm/amdgpu: fix runpm documentation

It's not only supported by HG/PX laptops.  It's supported
by all dGPUs which supports BOCO/BACO functionality (runtime
D3).

BOCO - Bus Off, Chip Off.  The entire chip is powered off.
       This is controlled by ACPI.
BACO - Bus Active, Chip Off.  The chip still shows up
       on the PCI bus, but the device itself is powered
       down.

v2: fix missed HG/PX reference

In function enable_stream_features(), the variable "old_downspread.raw"

used in the later if statement, and further, core_link_write_dpcd()
may write random value, which is potentially unsafe.

Subject: drm/amd/display: Fix underflow for fused display pipes case

[Why]
Depend on res_pool->res_cap->num_timing_generator to query timing
gernerator information, it would case underflow at the fused display
pipes case.
Due to the res_pool->res_cap->num_timing_generator records default
timing generator resource built in driver, not the current chip.

[How]
Some ASICs would be fused display pipes less than the default setting.
In dcnxx_resource_construct function, driver would obatin real timing
generator count and store it into res_pool->timing_generator_count.

Subject: drm/amd/display: unhard code link to phy idx mapping in dc link and
 clean up

[why]
1. Current code hard codes link to PHY mapping in dc link level per asic
per revision.
This is not scalable. In long term the mapping will be obatined from
DMUB and store in dc resource.

2. Depending on DCN revision and endpoint type, the definition of
dio_output_idx dio_output_type and phy_idx are not  consistent. We need
to unify the meaning of these hardware indices across different system
configuration.

[how]
1. Temporarly move the hardcoded mapping to dc_resource level, which
should have full awareness of asic specific configuration and add a TODO
comment to move the mapping to DMUB.

2. populate dio_output_idx/phy_idx for all configuration, define
usb4_enabled bit instead of dio_output_type as an external enum.

Subject: drm/amd/display: Don't reinitialize DMCUB on s0ix resume

[Why]
PSP will suspend and resume DMCUB. Driver should just wait for DMCUB to
finish the auto load before continuining instead of placing it into
reset, wiping its firmware state and reinitializing.

If we don't let DMCUB fully finish initializing for S0ix then some state
will be lost and screen corruption can occur due to incorrect address
translation.

[How]
Use dmub_srv callbacks to determine in DMCUB is running and wait for
auto-load to complete before continuining.

In S0ix DMCUB will be running and DAL fw so initialize will skip.

In S3 DMCUB will not be running and we will do a full hardware init.

In S3 DMCUB will be running but will not be DAL fw so we will also do
a full hardware init.

Subject: drm/amd/display: Add version check before using DP alt query
 interface

[Why]
To maintain compatibility with firmware older than 4.0.11.

Those firmware may have interrmittent hangs with RDCSPIPE or the PHY,
but we shouldn't regress their previous behavior.

[How]
Use the new path if firmware is development or 4.0.11 or newer. Use the
legacy path otherwise.

Fixes: 41f91315b5be5a ("drm/amd/display: Query DMCUB for dp alt status")

Subject: drm/i915: don't call free_mmap_offset when purging
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The TTM backend is in theory the only user here(also purge should only
be called once we have dropped the pages), where it is setup at object
creation and is only removed once the object is destroyed. Also
resetting the node here might be iffy since the ttm fault handler
uses the stored fake offset to determine the page offset within the pages
array.

This also blows up in the dontneed-before-mmap test, since the
expectation is that the vma_node will live on, until the object is
destroyed:

Don't attempt to fault and re-populate purged objects. By some fluke
this passes the dontneed-after-mmap IGT, but for the wrong reasons.

From 8ee262ba79a19a4dba9949397b1cf5761679670c Mon Sep 17 00:00:00 2001
From: Matthew Auld <matthew.auld@intel.com>
Date: Thu, 6 Jan 2022 17:49:09 +0000
Subject: drm/i915/ttm: add unmap_virtual callback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ensure we call ttm_bo_unmap_virtual when releasing the pages.
Importantly this should now handle the ttm swapping case, and all other
places that already call into i915_ttm_move_notify().

v2: fix up the selftest

Fixes: cf3e3e86d779 ("drm/i915: Use ttm mmap handling for ttm bo's.")

From 6ef295e34297433c78ea02dfcf1c649a769050bb Mon Sep 17 00:00:00 2001
From: Matthew Auld <matthew.auld@intel.com>
Date: Thu, 6 Jan 2022 17:49:10 +0000
Subject: drm/i915/ttm: ensure we unmap when purging
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Purging can happen during swapping out, or directly invoked with the
madvise ioctl. In such cases this doesn't involve a ttm move, which
skips umapping the object.

v2(Thomas):
- add ttm_truncate helper, and just call into i915_ttm_move_notify() to
  handle the unmapping step

Subject: Revert "drm/amd/display: Fix for otg synchronization logic"

This reverts commit a896f870f8a5f23ec961d16baffd3fda1f8be57c.

It causes odd flickering on my Radeon RX580 (PCI ID 1002:67df rev e7,
subsystem ID 1da2:e353).

Bisected right to this commit, and reverting it fixes things.

Subject: drm/sun4i: dw-hdmi: Fix missing put_device() call in
 sun8i_hdmi_phy_get

The reference taken by 'of_find_device_by_node()' must be released when
not needed anymore.
Add the corresponding 'put_device()' in the error handling path.

Subject: drm/atomic: Check new_crtc_state->active to determine if CRTC needs
 disable in self refresh mode

Actual hardware state of CRTC is controlled by the member 'active' in
struct drm_crtc_state instead of the member 'enable', according to the
kernel doc of the member 'enable'.  In fact, the drm client modeset
and atomic helpers are using the member 'active' to do the control.

Referencing the member 'enable' of new_crtc_state, the function
crtc_needs_disable() may fail to reflect if CRTC needs disable in
self refresh mode, e.g., when the framebuffer emulation will be blanked
through the client modeset helper with the next commit, the member
'enable' of new_crtc_state is still true while the member 'active' is
false, hence the relevant potential encoder and bridges won't be disabled.

So, let's check new_crtc_state->active to determine if CRTC needs disable
in self refresh mode instead of new_crtc_state->enable.

When UBSAN is enabled a case is shown on unplugging the display that
this variable hasn't been initialized by `update_dsc_caps`, presumably

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Do not allow exported amdgpu_gtt_mgr_*() to accept
any ttm_resource_manager pointer. Also there is no need
to force other module to call a ttm function just to
eventually call gtt_mgr functions.

v4: remove unused adev.
v3: upcast mgr from ttm resopurce manager instead of
getting it from adev.
v2: pass adev's gtt_mgr instead of adev.

Subject: drm/amdgpu: do not pass ttm_resource_manager to vram_mgr
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Do not allow exported amdgpu_vram_mgr_*() to accept
any ttm_resource_manager pointer. Also there is no need
to force other module to call a ttm function just to
eventually call vram_mgr functions.

v2: pass adev's vram_mgr instead of adev

Subject: drm/amdgpu: recover gart table at resume
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Get rid off pin/unpin of gart BO at resume/suspend and
instead pin only once and try to recover gart content
at resume time. This is much more stable in case there
is OOM situation at 2nd call to amdgpu_device_evict_resources()
while evicting GART table.

v3: remove gart recovery from other places
v2: pin gart at amdgpu_gart_table_vram_alloc()

Subject: drm/amd/amdgpu: Add pcie indirect support to
 amdgpu_mm_wreg_mmio_rlc()

The function amdgpu_mm_wreg_mmio_rlc() is used by debugfs to write to
MMIO registers.  It didn't support registers beyond the BAR mapped MMIO
space.  This adds pcie indirect write support.

There are currently 2 ways to create a set of sysfs files for a
kobj_type, through the default_attrs field, and the default_groups
field.  Move the amdgpu sysfs code to use default_groups field which has
been the preferred way since aa30f47cf666 ("kobject: Add support for
default attribute groups to kobj_type") so that we can soon get rid of
the obsolete default_attrs field.

is used before the check.

Initialize the "dev" variable after the sanity check to avoid a possible
NULL pointer dereference.

Subject: drm/amdkfd: Check for null pointer after calling kmemdup

As the possible failure of the allocation, kmemdup() may return NULL
pointer.
Therefore, it should be better to check the 'props2' in order to prevent
the dereference of NULL pointer.

Subject: drm/amdkfd: Use prange->list head for insert_list

There are seven list_heads in struct svm_range: list, update_list,
remove_list, insert_list, svm_bo_list, deferred_list, child_list. This
patch and the next one remove two of them that are redundant.

The insert_list head was only used for new ranges that are not on the
svms->list yet. So we can use that list head for keeping track of
new ranges before they get added, and use list_move_tail to move them
to the svms->list when ready.

Subject: drm/amdkfd: Use prange->update_list head for remove_list

The remove_list head was only used for keeping track of existing ranges
that are to be removed from the svms->list. The update_list was used for
new or existing ranges that need updated attributes. These two cases are
mutually exclusive (i.e. the same range will never be on both lists).
Therefore we can use the update_list head to track the remove_list and
save another 16 bytes in the svm_range struct.

Subject: drm/amdgpu: Use correct VIEWPORT_DIMENSION for DCN2
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For some reason this file isn't using the appropriate register
headers for DCN headers, which means that on DCN2 we're getting
the VIEWPORT_DIMENSION offset wrong.

This means that we're not correctly carving out the framebuffer
memory correctly for a framebuffer allocated by EFI and
therefore see corruption when loading amdgpu before the display
driver takes over control of the framebuffer scanout.

Fix this by checking the DCE_HWIP and picking the correct offset
accordingly.

Long-term we should expose this info from DC as GMC shouldn't
need to know about DCN registers.

Subject: drm/amdkfd: Fix DQM asserts on Hawaii

start_nocpsch would never set dqm->sched_running on Hawaii due to an
early return statement. This would trigger asserts in other functions
and end up in inconsistent states.

Subject: drm/ttm: fix compilation on ARCH=um

Even if it's probably not really useful, it can get selected
by e.g. randconfig builds, and then failing to compile is an
annoyance. Unfortunately, it's hard to fix in Kconfig, since
DRM_TTM is selected by many things that don't really depend
on any specific architecture, and just depend on PCI (which
is indeed now available in ARCH=um via simulation/emulation).

Fix this in the code instead by just ifdef'ing the relevant
two lines that depend on "real X86".

Subject: drm/amdgpu: Fix rejecting Tahiti GPUs

eb4fd29afd4a ("drm/amdgpu: bind to any 0x1002 PCI diplay class device") added
generic bindings to amdgpu so that that it binds to all display class devices
with VID 0x1002 and then rejects those in amdgpu_pci_probe.

Unfortunately it reuses a driver_data value of 0 to detect those new bindings,
which is already used to denote CHIP_TAHITI ASICs.

The driver_data value given to those new bindings was changed in
dd0761fd24ea1 ("drm/amdgpu: set CHIP_IP_DISCOVERY as the asic type by default")
to CHIP_IP_DISCOVERY (=36), but it seems that the check in amdgpu_pci_probe
was forgotten to be changed. Therefore, it still rejects Tahiti GPUs.

Link: https://gitlab.freedesktop.org/drm/amd/-/issues/1860
Fixes: eb4fd29afd4a ("drm/amdgpu: bind to any 0x1002 PCI diplay class device")

Subject: drm/amdgpu: drop flags check for CHIP_IP_DISCOVERY

Support for IP based discovery is in place now so this
check is no longer required.

Subject: drm/amd/display: Revert W/A for hard hangs on DCN20/DCN21

The WA from commit 2a50edbf10c8 ("drm/amd/display: Apply w/a for hard hang
on HPD") and commit 1bd3bc745e7f ("drm/amd/display: Extend w/a for hard
hang on HPD to dcn20") causes a regression in s0ix where the system will
fail to resume properly on many laptops.  Pull the workarounds out to
avoid that s0ix regression in the common case.  This HPD hang happens with
an external device in special circumstances and a new W/A will need to be
developed for this in the future.

Subject: virtio: wrap config->reset calls

This will enable cleanups down the road.
The idea is to disable cbs, then add "flush_queued_cbs" callback
as a parameter, this way drivers can flush any work
queued after callbacks have been disabled.

Subject: Replace for_each_*_bit_from() with for_each_*_bit() where appropriate

A couple of kernel functions call for_each_*_bit_from() with start
bit equal to 0. Replace them with for_each_*_bit().

No functional changes, but might improve on readability.

Subject: drm/amd/amdgpu: fixing read wrong pf2vf data in SRIOV

[Why]
This fixes 892deb48269c ("drm/amdgpu: Separate vf2pf work item init from virt data exchange").
we should read pf2vf data based at mman.fw_vram_usage_va after gmc
sw_init. commit 892deb48269c breaks this logic.

[How]
calling amdgpu_virt_exchange_data in amdgpu_virt_init_data_exchange to
set the right base in the right sequence.

v2:
call amdgpu_virt_init_data_exchange after gmc sw_init to make data
exchange workqueue run

v3:
clean up the code logic

v4:
add some comment and make the code more readable

Subject: i915: simplify subdirectory registration with register_sysctl()

There is no need to user boiler plate code to specify a set of base
directories we're going to stuff sysctls under.  Simplify this by using
register_sysctl() and specifying the directory path directly.

Subject: lib/stackdepot: allow optional init and stack_table allocation by
 kvmalloc()

Currently, enabling CONFIG_STACKDEPOT means its stack_table will be
allocated from memblock, even if stack depot ends up not actually used.
The default size of stack_table is 4MB on 32-bit, 8MB on 64-bit.

This is fine for use-cases such as KASAN which is also a config option
and has overhead on its own.  But it's an issue for functionality that
has to be actually enabled on boot (page_owner) or depends on hardware
(GPU drivers) and thus the memory might be wasted.  This was raised as
an issue [1] when attempting to add stackdepot support for SLUB's debug
object tracking functionality.  It's common to build kernels with
CONFIG_SLUB_DEBUG and enable slub_debug on boot only when needed, or
create only specific kmem caches with debugging for testing purposes.

It would thus be more efficient if stackdepot's table was allocated only
when actually going to be used.  This patch thus makes the allocation
(and whole stack_depot_init() call) optional:

 - Add a CONFIG_STACKDEPOT_ALWAYS_INIT flag to keep using the current
   well-defined point of allocation as part of mem_init(). Make
   CONFIG_KASAN select this flag.

 - Other users have to call stack_depot_init() as part of their own init
   when it's determined that stack depot will actually be used. This may
   depend on both config and runtime conditions. Convert current users
   which are page_owner and several in the DRM subsystem. Same will be
   done for SLUB later.

 - Because the init might now be called after the boot-time memblock
   allocation has given all memory to the buddy allocator, change
   stack_depot_init() to allocate stack_table with kvmalloc() when
   memblock is no longer available. Also handle allocation failure by
   disabling stackdepot (could have theoretically happened even with
   memblock allocation previously), and don't unnecessarily align the
   memblock allocation to its own size anymore.

Subject: lib/stackdepot: allow optional init and stack_table allocation by kvmalloc() - fixup

On FLATMEM, we call page_ext_init_flatmem_late() just before
kmem_cache_init() which means stack_depot_init() (called by page owner
init) will not recognize properly it should use kvmalloc() and not
memblock_alloc().  memblock_alloc() will also not issue a warning and
return a block memory that can be invalid and cause kernel page fault when
saving stacks, as reported by the kernel test robot [1].

Fix this by moving page_ext_init_flatmem_late() below kmem_cache_init() so
that slab_is_available() is true during stack_depot_init().  SPARSEMEM
doesn't have this issue, as it doesn't do page_ext_init_flatmem_late(),
but a different page_ext_init() even later in the boot process.

Thanks to Mike Rapoport for pointing out the FLATMEM init ordering issue.

While at it, also actually resolve a checkpatch warning in stack_depot_init()
from DRM CI, which was supposed to be in the original patch already.

Subject: drm/atomic: Add the crtc to affected crtc only if uapi.enable = true
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In case of a modeset where a mode gets split across multiple CRTCs
in the driver specific implementation (bigjoiner in i915) we wrongly count
the affected CRTCs based on the drm_crtc_mask and indicate the stolen CRTC as
an affected CRTC in atomic_check_only().
This triggers a warning since affected CRTCs doent match requested CRTC.

To fix this in such bigjoiner configurations, we should only
increment affected crtcs if that CRTC is enabled in UAPI not
if it is just used internally in the driver to split the mode.

v3: Add the same uapi crtc_state->enable check in requested
crtc calc (Ville)

Subject: drm/msm/gpu: Wait for idle before suspending

System suspend uses pm_runtime_force_suspend(), which cheekily bypasses
the runpm reference counts.  This doesn't actually work so well when the
GPU is active.  So add a reasonable delay waiting for the GPU to become
idle.

Alternatively we could just return -EBUSY in this case, but that has the
disadvantage of causing system suspend to fail.

v2: s/ret/remaining [sboyd], and switch to using active_submits count
    to ensure we aren't racing with submit cleanup (and devfreq idle
    work getting scheduled, etc)
v3: fix inverted logic

Subject: drm/msm/gpu: Cancel idle/boost work on suspend

With system suspend using pm_runtime_force_suspend() we can't rely on
the pm_runtime_get_if_in_use() trick to deal with devfreq callbacks
after (or racing with) suspend.  So flush any pending idle or boost
work in the suspend path.

Subject: drm/etnaviv: relax submit size limits

While all userspace tried to limit commandstreams to 64K in size,
a bug in the Mesa driver lead to command streams of up to 128K
being submitted. Allow those to avoid breaking existing userspace.

Subject: drm/i915: Flush TLBs before releasing backing store

We need to flush TLBs before releasing backing store otherwise userspace
is able to encounter stale entries if a) it is not declaring access to
certain buffers and b) it races with the backing store release from a
such undeclared execution already executing on the GPU in parallel.

The approach taken is to mark any buffer objects which were ever bound
to the GPU and to trigger a serialized TLB flush when their backing
store is released.

Alternatively the flushing could be done on VMA unbind, at which point
we would be able to ascertain whether there is potential a parallel GPU
execution (which could race), but essentially it boils down to paying
the cost of TLB flushes potentially needlessly at VMA unbind time (when
the backing store is not known to be going away so not needed for
safety), versus potentially needlessly at backing store relase time
(since we at that point cannot tell whether there is anything executing
on the GPU which uses that object).

Thereforce simplicity of implementation has been chosen for now with
scope to benchmark and refine later as required.

Subject: drm/amd/display: Fix for otg synchronization logic

[Why]
During otg sync trigger, plane states are used to decide whether the otg
is already synchronized or not. There are scenarions when otgs are
disabled without plane state getting disabled and in such case the otg is
excluded from synchronization.

[How]
Introduced pipe_idx_syncd in pipe_ctx that tracks each otgs master pipe.
When a otg is disabled/enabled, pipe_idx_syncd is reset to itself.
On sync trigger, pipe_idx_syncd is checked to decide whether a otg is
already synchronized and the otg is further included or excluded from
synchronization.

v2:
  Don't drop is_blanked logic

Subject: drm/amd/display: Correct MPC split policy for DCN301

[Why]
DCN301 has seamless boot enabled. With MPC split enabled
at the same time, system will hang.

[How]
Revert MPC split policy back to "MPC_SPLIT_AVOID". Since we have
ODM combine enabled on DCN301, pipe split is not necessary here.

Subject: drm/amd/display: change FIFO reset condition to embedded display only

[Why]
FIFO reset is only necessary for fast boot sequence, where otg is disabled
and dig fe is enabled when changing dispclk. Fast boot is only enabled
on embedded displays.

[How]
Change FIFO reset condition to "embedded display only".

Subject: drm/amdgpu: filter out radeon secondary ids as well
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Older radeon boards (r2xx-r5xx) had secondary PCI functions
which we solely there for supporting multi-head on OSs with
special requirements.  Add them to the unsupported list
as well so we don't attempt to bind to them.  The driver
would fail to bind to them anyway, but this does so
in a cleaner way that should not confuse the user.

Subject: drm/amdgpu/display: adjust msleep limit in
 dp_wait_for_training_aux_rd_interval

Some architectures (e.g., ARM) have relatively low udelay limits.
On most architectures, anything longer than 2000us is not recommended.
Change the check to align with other similar checks in DC.

Subject: drm/amdgpu/display: use msleep rather than udelay for long delays

Some architectures (e.g., ARM) throw an compilation error if the
udelay is too long.  In general udelays of longer than 2000us are
not recommended on any architecture.  Switch to msleep in these
cases.

Subject: drm/amd/display/dc/calcs/dce_calcs: Fix a memleak in
 calculate_bandwidth()

In calculate_bandwidth(), the tag free_sclk and free_yclk are reversed,
which could lead to a memory leak of yclk.

Fix this bug by changing the location of free_sclk and free_yclk.

This bug was found by a static analyzer.

Builds with 'make allyesconfig' show no new warnings,
and our static analyzer no longer warns about this code.

Subject: drm/amdgpu/display: Remove t_srx_delay_us.

Unused. Convert the divisions into asserts on the divisor, to
debug why it is zero. The divide by zero is suspected of causing
kernel panics.

While I have no idea where the zero is coming from I think this
patch is a positive either way.

Subject: drm/privacy-screen: honor acpi=off in detect_thinkpad_privacy_screen

when acpi=off is provided in bootarg, kernel crash with

[    1.252739] BUG: kernel NULL pointer dereference, address: 0000000000000018
[    1.258308] Call Trace:
[    1.258490]  ? acpi_walk_namespace+0x147/0x147
[    1.258770]  acpi_get_devices+0xe4/0x137

[    1.259337]  drm_privacy_screen_lookup_init+0xe/0xe85 [drm]

The reason is that acpi_walk_namespace expects acpi related stuff
initialized but in fact it wouldn't when acpi is set to off. In this case
we should honor acpi=off in detect_thinkpad_privacy_screen().

Subject: drm/vmwgfx: Fix stale file descriptors on failed usercopy

A failing usercopy of the fence_rep object will lead to a stale entry in
the file descriptor table as put_unused_fd() won't release it. This
enables userland to refer to a dangling 'file' object through that still
valid file descriptor, leading to all kinds of use-after-free
exploitation scenarios.

Fix this by deferring the call to fd_install() until after the usercopy
has succeeded.
