Various DCE versions had trouble with 36 bpp lb depth, requiring fixes,
last time in commit 353ca0fa5630 ("drm/amd/display: Fix 10bit 4K display
on CIK GPUs") for DCE-8. So far >= DCE-11.2 was considered ok, but now I
found out that on DCE-11.2 it causes dithering when there shouldn't be
any, so identity pixel passthrough with identity gamma LUTs doesn't work
when it should. This breaks various important neuroscience applications,
as reported to me by scientific users of Polaris cards under Ubuntu 22.04
with Linux 5.15, and confirmed by testing it myself on DCE-11.2.
Lets only use depth 36 for DCN engines, where my testing showed that it
is both necessary for high color precision output, e.g., RGBA16 fb's,
and not harmful, as far as more than one year in real-world use showed.
DCE engines seem to work fine for high precision output at 30 bpp, so
this ("famous last words") depth 30 should hopefully fix all known problems
without introducing new ones.
Successfully retested on DCE-11.2 Polaris and DCN-1.0 Raven Ridge on
top of Linux 5.19.0-rc2 + drm-next.

[why]
First MST sideband message returns AUX_RET_ERROR_HPD_DISCON

if HPD unexpected pulled low. The actual aux transaction success
in such case, hence do not return error.

This driver currently prints the link status using four separate
printk calls, which these days gets presented to the user as four
distinct messages, not exactly ideal:
[ 32.582778] eth0: Link is up using
[ 32.582828] internal
[ 32.582837] transceiver at
[ 32.582888] 100Mb/s, Full Duplex.
Restructure the display_link_mode function to use a single netdev_info
call to present all this information as a single message, which is much
nicer:
[ 33.640143] hme 0000:00:01.1 eth0: Link is up using internal transceiver at 100Mb/s, Full Duplex.
The display_forced_link_mode function has a similar structure, so adjust
it in a similar fashion.

The upper 32-bit PHC register is not latched when reading the lower

This patch fixes this by reading higher order bits twice and makes

bnxt_reinit_after_abort() is called during ifup when a previous
FW reset sequence has aborted or a previous ifup has failed after
detecting FW reset. In all cases, it is safe to assume that a
previous FW reset has completed and the driver may not have fully
reinitialized.
Prior to this patch, it is assumed that the
FUNC_DRV_IF_CHANGE_RESP_FLAGS_HOT_FW_RESET_DONE flag will always be
set by the firmware in bnxt_hwrm_if_change(). This may not be true if
the driver has already attempted to register with the firmware. The
firmware may not set the RESET_DONE flag again after the driver has
registered, assuming that the driver has seen the flag already.
Fix it to always go through the FW reset initialization path if
the BNXT_STATE_FW_RESET_DET flag is set. This flag is always set
by the driver after successfully going through bnxt_reinit_after_abort().

We employ a "waitboost" heuristic to detect when userspace is stalled
waiting for results from earlier execution. Under latency sensitive work
mixed between the gpu/cpu, the GPU is typically under-utilised and so
RPS sees that low utilisation as a reason to downclock the frequency,
causing longer stalls and lower throughput. The user left waiting for
the results is not impressed.
On applying commit 047a1b877ed4 ("dma-buf & drm/amdgpu: remove dma_resv
workaround") it was observed that deinterlacing h264 on Haswell
performance dropped by 2-5x. The reason being that the natural workload
was not intense enough to trigger RPS (using HW evaluation intervals) to
upclock, and so it was depending on waitboosting for the throughput.
Commit 047a1b877ed4 ("dma-buf & drm/amdgpu: remove dma_resv workaround")
changes the composition of dma-resv from keeping a single write fence +
multiple read fences, to a single array of multiple write and read
fences (a maximum of one pair of write/read fences per context). The
iteration order was also changed implicitly from all-read fences then
the single write fence, to a mix of write fences followed by read
fences. It is that ordering change that belied the fragility of
waitboosting.
Currently, a waitboost is inspected at the point of waiting on an
outstanding fence. If the GPU is backlogged such that we haven't yet
stated the request we need to wait on, we force the GPU to upclock until
the completion of that request. By changing the order in which we waited
upon requests, we ended up waiting on those requests in sequence and as
such we saw that each request was already started and so not a suitable
candidate for waitboosting.
Instead of asking whether to boost each fence in turn, we can look at
whether boosting is required for the dma-resv ensemble prior to waiting
on any fence, making the heuristic more robust to the order in which
fences are stored in the dma-resv.

Avoid trying to invalidate the TLB in the middle of performing an
engine reset, as this may result in the reset timing out. Currently,
the TLB invalidate is only serialised by its own mutex, forgoing the
uncore lock, but we can take the uncore->lock as well to serialise
the mmio access, thereby serialising with the GDRST.

In vma destruction, the following race may occur:

...
list_del_init(vma->vm_link);
...
mutex_unlock(vma->vm->mutex);
__i915_vm_release();
release_references();
And in release_reference() we dereference vma->vm to get to the
vm gt pointer, leading to a use-after free.
However, __i915_vm_release() grabs the vm->mutex so the vm won't be
destroyed before vma->vm->mutex is released, so extract the gt pointer
under the vm->mutex to avoid the vma->vm dereference in
release_references().

When creating a snapshot of the NVM the driver needs to read the entire
contents from the NVM and store it. The NVM reads are protected by a lock
that is shared between the driver and the firmware.
If the driver takes too long to read the entire NVM (which can happen on
some systems) then the firmware could reclaim the lock and cause subsequent
reads from the driver to fail.
We could fix this by increasing the timeout that we pass to the firmware,
but we could end up in the same situation again if the system is slow.
Instead have the driver break the reading of the NVM into blocks that are
small enough that we have confidence that the read will complete within the
timeout time, but large enough not to cause significant AQ overhead.

The chip_name configs attribute always displays the device name of the

wrong.
Fix it by correctly comparing the bank's swnode against the GPIO

The error paths of gntdev_mmap() can call unmap_grant_pages() even
though not all of the pages have been successfully mapped. This will
trigger the WARN_ON()s in __unmap_grant_pages_done(). The number of
warnings can be very large; I have observed thousands of lines of
warnings in the systemd journal.
Avoid this problem by only warning on unmapping failure if the handle
being unmapped is not INVALID_GRANT_HANDLE. The handle field of any
page that was not successfully mapped will be INVALID_GRANT_HANDLE, so
this catches all cases where unmapping can legitimately fail.

Taking the qos_mutex to process RoCEv2 QP's on netdev events causes a
kernel splat.
Fix this by removing the handling for RoCEv2 in
irdma_cm_teardown_connections that uses the mutex. This handling is only
needed for iWARP to avoid having connections established while the link is
down or having connections remain functional after the IP address is
removed.

This is a collection of three fixes for small annoyances.
Two of these are already pending in other trees, but I really don't want
to release another -rc with these issues pending, so I picked up the
patches for these things directly. We'll end up with duplicate commits
eventually, I prefer that over having these issues pending.
The third one is just me getting rid of another BUG_ON() just because it
was reported and I dislike those things so much.

Commit 98f30d0ecf79 ("ACPI: power: Switch to sys-off handler API")
switched the ACPI sleep code from directly setting the old global
pm_power_off handler to using the new register_sys_off_handler()
mechanism with a priority of SYS_OFF_PRIO_FIRMWARE.
This is a problem when the old global pm_power_off handler would later
be overwritten, such as done by the late_initcall(efi_shutdown_init):
if (efi_poweroff_required())
pm_power_off = efi_power_off;
The old global pm_power_off handler gets run with a priority of
SYS_OFF_PRIO_DEFAULT which is lower then SYS_OFF_PRIO_FIRMWARE, causing
acpi_power_off() to run first, changing the behavior from before
the ACPI sleep code switched to the new register_sys_off_handler().
Switch the registering of efi_power_off over to register_sys_off_handler()
with a priority of SYS_OFF_PRIO_FIRMWARE + 1 so that it will run before
acpi_power_off() as before.
Note since the new sys-off-handler code will try all handlers in
priority order, there is no more need for the EFI code to store and
call the original pm_power_off handler.
