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.

Looks like our VBIOS/GOP generally fail to turn the DP dual mode adater
TMDS output buffers back on after a reboot. This leads to a black screen
after reboot if we turned the TMDS output buffers off prior to reboot.
And if i915 decides to do a fastboot the black screen will persist even
after i915 takes over.
Apparently this has been a problem ever since commit b2ccb822d376 ("drm/i915:
Enable/disable TMDS output buffers in DP++ adaptor as needed") if one
rebooted while the display was turned off. And things became worse with
commit fe0f1e3bfdfe ("drm/i915: Shut down displays gracefully on reboot")
since now we always turn the display off before a reboot.
This was reported on a RKL, but I confirmed the same behaviour on my
SNB as well. So looks pretty universal.
Let's fix this by explicitly turning the TMDS output buffers back on
in the encoder->shutdown() hook. Note that this gets called after irqs
have been disabled, so the i2c communication with the DP dual mode
adapter has to be performed via polling (which the gmbus code is
perfectly happy to do for us).
We also need a bit of care in handling DDI encoders which may or may
not be set up for HDMI output. Specifically ddc_pin will not be
populated for a DP only DDI encoder, in which case we don't want to
call intel_gmbus_get_adapter(). We can handle that by simply doing
the dual mode adapter type check before calling
intel_gmbus_get_adapter().

We will need to do some i2c poking from the encoder->shutdown() hook.
Currently that gets called after irqs have been turned off. We still
poll the gmbus status bits even if the interrupt never arrives so
things will work just fine. But seems like asking gmbus to generate
interrupts we will never see is a bit pointless, so don't.

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.

Commit 1bdb542da736 ("drm/ingenic: Simplify code by using hwdescs
array") caused the dma_hwdesc_phys_f{0,1} variables to be used while
uninitialized in a mmio register write, which most certainly broke the
ingenic-drm driver.
However, the very same patchset also submitted commit 6055466203df
("drm/ingenic: Upload palette before frame"), which restored a correct
behaviour by doing the register writes in a different place in the code.
What's left of this, is just to remove the bogus register writes in the
probe function.

Setting the DMA descriptor chain register in the probe function has been
fine until now, because we only ever had one descriptor per foreground.
As the driver will soon have real descriptor chains, and the DMA
descriptor chain register updates itself to point to the current
descriptor being processed, this register needs to be reset after a full
modeset to point to the first descriptor of the chain.

By using the modifier plane capability flags to encode the modifiers'
CCS type and tiling attributes, it becomes simpler to the check for
any of these capabilities when providing the list of supported
modifiers.
This also allows distinguishing modifiers on future platforms where
platforms with the same display version support different modifiers. An
example is DG2 and ADLP, both being D13, where DG2 supports only F and X
tiling, while ADLP supports only Y and X tiling. With the
INTEL_PLANE_CAP_TILING_* flags added in this patch we can provide
the correct modifiers for each platform.
v2:
- Define PLANE_HAS_* with macros instead of an enum. (Jani)
- Rename PLANE_HAS_*_ANY to PLANE_HAS_*_MASK. (Jani)
- Rename PLANE_HAS_* to INTEL_PLANE_CAP_*.
- Set the CCS_RC_CC cap only for DISPLAY_VER >= 12.
- Set the TILING_Y cap only for DISPLAY_VER < 13 || ADLP.
- Simplify the SKL plane cap display version checks and move them
to a separate function.

[Why]
- DPIA MST slot registers are not programmed during payload
allocation and hence MST does not work with DPIA.
- HPD RX interrupts are not handled for DPIA.
[How]
- Added inbox command to program the MST slots whenever
payload allocation happens for DPIA links.
- Added support for handling HPD RX interrupts

[Why]
DMUB binary is common for both A0 and B0. Hence, driver should
notify FW about the support for DPIA in B0.
[How]
Added dpia_supported bit in dmub_fw_boot_options and will be set
only for B0.
Assign dpia_supported to true before dm_dmub_hw_init
in B0 case.

[Why]
Notify data from outbox corrupt, the notify type should be 2 (HPD) instead of 0
(No data). We copied the address instead of the value. The memory might be
freed in the end of outbox IRQ
[How]
We should allocate the memory of notify and copy the whole content from outbox to
hpd handle function

[Why]
A deadlock in the kernel occurs when we fallback from the V3 to V2
add_topology_to_display or remove_topology_to_display because they
both try to acquire the dtm_mutex but recursive locking isn't
supported on mutex_lock().
[How]
Make the mutex_lock/unlock more fine grained and move them up such that
they're only required for the psp invocation itself.

[WHY]
On certain configs, SMU clock table voltages don't match which cause parser
to behave incorrectly by leaving dcfclk and socclk table entries unpopulated.
[HOW]
Currently the function that finds the corresponding clock for a given voltage
only checks for exact voltage level matches. In the case that no match gets
found, parser now falls back to searching for the max clock which meets the
requested voltage (i.e. its corresponding voltage is below requested).

[why]
We have a regression that cause maximize lane settings to use
uninitialized data from unused lanes.
This will cause link training to fail for 1 or 2 lanes because the lane
adjust is populated incorrectly sometimes.

[why]
As DP features expands, we have encountered many situations where we
must configure a different DPCD lane setting from hw lane settings we
output. The change is to decouple hw lane settings from dpcd lane
settings to provide flexibility to configure dpcd and hw individually.
