When changing the DISPCLK_WDIVIDER value from 126 to 127, the change in
clock rate is too great for the FIFOs to handle. This can cause visible
corruption during clock change.
HW has handed down this register sequence to fix the issue.
[HOW]
The sequence, from HW:
a. 127 -> 126
Read DIG_FIFO_CAL_AVERAGE_LEVEL
FIFO level N = DIG_FIFO_CAL_AVERAGE_LEVEL / 4
Set DCCG_FIFO_ERRDET_OVR_EN = 1
Write 1 to OTGx_DROP_PIXEL for (N-4) times
Set DCCG_FIFO_ERRDET_OVR_EN = 0
Write DENTIST_DISPCLK_RDIVIDER = 126
Because of frequency stepping, sequence a can be executed to change the
divider from 127 to any other divider value.
b. 126 -> 127
Read DIG_FIFO_CAL_AVERAGE_LEVEL
FIFO level N = DIG_FIFO_CAL_AVERAGE_LEVEL / 4
Set DCCG_FIFO_ERRDET_OVR_EN = 1
Write 1 to OTGx_ADD_PIXEL for (12-N) times
Set DCCG_FIFO_ERRDET_OVR_EN = 0
Write DENTIST_DISPCLK_RDIVIDER = 127
Because of frequency stepping, divider must first be set from any other
divider value to 126 before executing sequence b.

[WHY]
Some DPCD addresses, notably LTTPR Capability registers, are expected to
be read all together in a single DPCD transaction. Rather than force callers to
read registers they don't need, we want to quietly extend the addresses
read, and only return back the values the caller asked for.
This does not affect DPCD writes.
[HOW]
Create an additional layer above AUX to perform 'checked' DPCD
transactions.
Iterate through an array of DPCD address ranges that are marked as being
contiguous. If a requested read falls within one of those ranges, extend
the read to include the entire range.
After DPCD has been queried, copy the requested bytes into the caller's
data buffer, and deallocate all resources used.

Instead of reading the desired 5 bytes of the actual target field,
the code was reading 8. This could result in a corrupted value if the
trailing 3 bytes were non-zero, so instead use an appropriately sized

[why]
Link rate in kHz is what is eventually required to calculate the link
bandwidth, which makes kHz a more generic unit. This should also make
forward-compatibility with new DP standards easier.
[how]
- Replace 'link rate DPCD code' with 'link rate in kHz' when used with
drm_dp_mst_topology_mgr_init()
- Add/remove related DPCD code conversion from/to kHz where applicable

This is intended to enable direct high-precision scanout and pageflip
of Vulkan swapchain images in format VK_FORMAT_R16G16B16A16_UNORM.
Expose DRM_FORMAT_XRGB16161616, DRM_FORMAT_ARGB16161616,
DRM_FORMAT_XBGR16161616 and DRM_FORMAT_ABGR16161616 as 16 bpc
unsigned normalized formats. These allow to take full advantage
of the maximum precision of the display hardware, ie. currently
up to 12 bpc.
Searching through old AMD M56, M76 and RV630 hw programming docs
suggests that these 16 bpc formats are supported by all DCE and
DCN display engines, so we can expose the formats unconditionally.
Successfully tested on AMD Polaris11 DCE-11.2 an RavenRidge DCN-1.0
with a HDR-10 monitor over 10 bpc DP output with spatial dithering
enabled by the driver. Picture looks good, and my photometer
measurement procedure confirms an effective 12 bpc color
reproduction.

This is needed to avoid warnings with linebuffer depth 36 bpp.
Testing on a Polaris11, DCE-11.2 on a 10 bit HDR-10 monitor
showed no obvious problems, and this 12 bpc limit is consistent
with what other function in the DCE bit depth reduction path use.

Testing with the photometer shows that at least Raven Ridge DCN-1.0
does not achieve more than 10 bpc effective output precision with a
16 bpc unorm surface of type SURFACE_PIXEL_FORMAT_GRPH_ABGR16161616,
unless linebuffer depth is increased from LB_PIXEL_DEPTH_30BPP to
LB_PIXEL_DEPTH_36BPP. Otherwise precision gets truncated somewhere
to 10 bpc effective depth.
Strangely this increase was not needed on Polaris11 DCE-11.2 during
testing to get 12 bpc effective precision. It also is not needed for
fp16 framebuffers.
Tested on DCN-1.0 and DCE-11.2.

Add the necessary format definition, bandwidth and pixel size mappings,
prescaler setup, and pixelformat selection, following the logic
already present for SURFACE_PIXEL_FORMAT_GRPH_ARGB16161616.
The new SURFACE_PIXEL_FORMAT_GRPH_ABGR16161616 is implemented as the
old SURFACE_PIXEL_FORMAT_GRPH_ARGB16161616 format, but with swapped
red <-> green color channel, by use of the hardware xbar.
Please note that on the DCN 1/2/3 display engines, the pixelformat
in hubp and dpp setup for the old SURFACE_PIXEL_FORMAT_GRPH_ARGB16161616
and the new SURFACE_PIXEL_FORMAT_GRPH_ABGR16161616 was changed from
format id 22 to id 26. See amd/include/navi10_enum.h for the meaning
of the id's.
For format 22, the display engine read the framebuffer in 16 bpc format,
but truncated to the 12 bpc actually supported by later pipeline stages.
However, the engine took the 12 LSB of each color component for
truncation, which is incompatible with rendering at least under Vulkan,
where content is 16 bit wide, and a 12 MSB alignment would be appropriate,
if any. Format 20 for ARGB16161616_12MSB does work, but even better, we
can choose format 26 for ARGB16161616_UNORM, keeping all 16 bits around
until later stages of the display pipeline.
This allows to directly consume what the rendering hw produces under
Vulkan for swapchain format VK_FORMAT_R16G16B16A16_UNORM, as tested
with a patched version of the current AMD open-source amdvlk driver
which maps swapchain format VK_FORMAT_R16G16B16A16_UNORM onto
DRM_FORMAT_XBGR16161616.
The old id 22 would cause colorful pixeltrash to be displayed instead.
Tested under DCN-1.0 and DCE-11.2.

A few weeks ago, we saw a two cursor issue in a ChromeOS system. We
fixed it in the commit:
drm/amd/display: Fix two cursor duplication when using overlay
(read the commit message for more details)
After this change, we noticed that some IGT subtests related to
kms_plane and kms_plane_scaling started to fail. After investigating
this issue, we noticed that all subtests that fail have a primary plane
covering the overlay plane, which is currently rejected by amdgpu dm.
Fail those IGT tests highlight that our verification was too broad and
compromises the overlay usage in our drive. This patch fixes this issue
by ensuring that we only reject commits where the primary plane is not
fully covered by the overlay when the cursor hardware is enabled. With
this fix, all IGT tests start to pass again, which means our overlay
support works as expected.

[Why]
FS video support regressed GPU scaling and the scaled buffer ends up
stuck in the top left of the screen at native size - full, aspect,
center scaling modes do not function.
This is because decide_crtc_timing_for_drm_display_mode() does not
get called when scaling is enabled.
[How]
Split recalculate timing and scaling into two different flags.
We don't want to call drm_mode_set_crtcinfo() for scaling, but we
do want to call it for FS video.
Optimize and move preferred_refresh calculation next to
decide_crtc_timing_for_drm_display_mode() like it used to be since
that's not used for FS video.
We don't need to copy over the VIC or polarity in the case of FS video
modes because those don't change.

[Why]
Conditions that end up modifying the global dc state must be locked.
However, during mst allocate payload sequence, lock is already taken.
With StarTech 1.2 DP hub, we get an HPD RX interrupt for a reason other
than to indicate down reply availability right after sending payload
allocation. The handler again takes dc lock before calling the
dc's HPD RX handler. Due to this contention, the DRM thread which waits
for MST down reply never gets a chance to finish its waiting
successfully and ends up timing out. Once the lock is released, the hpd
rx handler fires and goes ahead to read from the MST HUB, but now its
too late and the HUB doesnt lightup all displays since DRM lacks error
handling when payload allocation fails.
[How]
Take lock only if there is a change in link status or if automated test
pattern bit is set. The latter fixes the null pointer dereference when
running certain DP Link Layer Compliance test.
