drm/amdkfd: Disable SVM per GPU, not per process
When some GPUs don't support SVM, don't disabe it for the entire process.
That would be inconsistent with the information the process got from the

Instead disable SVM support only for the unsupported GPUs. This is done
by checking any per-device attributes against the bitmap of supported

new SVM address ranges.

drm/amd/display: Cover edge-case when changing DISPCLK WDIVIDER
[WHY]
When changing the DISPCLK_WDIVIDER value from 126 to 127, the change in

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

Write 1 to OTGx_DROP_PIXEL for (N-4) times
Set DCCG_FIFO_ERRDET_OVR_EN = 0

Because of frequency stepping, sequence a can be executed to change the
divider from 127 to any other divider value.
b. 126 -> 127

FIFO level N = DIG_FIFO_CAL_AVERAGE_LEVEL / 4

[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.

drm/amdgpu/vcn: drop gfxoff control for VCN2+
Drop disabling of gfxoff during VCN use. This allows gfxoff
to kick in and potentially save power if the user is not using
gfx for color space conversion or scaling.
VCN1.0 had a bug which prevented it from working properly with
gfxoff, so we disabled it while using VCN. That said, most apps
today use gfx for scaling and color space conversion rather than
overlay planes so it was generally in use anyway. This was fixed
on VCN2+, but since we mostly use gfx for color space conversion
and scaling and rapidly powering up/down gfx can negate the
advantages of gfxoff, we left gfxoff disabled. As more
applications use overlay planes for color space conversion
and scaling, this starts to be a win, so go ahead and leave
gfxoff enabled.
Note that VCN1.0 uses vcn_v1_0_idle_work_handler() and
vcn_v1_0_ring_begin_use() so they are not affected by this
patch.

drm/i915/adl_p: Same slices mask is not same Dbuf state
We currently treat same slice mask as a same DBuf state and skip
updating the Dbuf slices, if we detect that.
This is wrong as if we have a multi to single pipe change or
vice versa, that would be treated as a same Dbuf state and thus
no changes required, so we don't get Mbus updated, causing issues.
Solution: check also mbus_join, in addition to slices mask.

drm/i915/display: Introduce new intel_psr_pause/resume function
This introduces the following function that can exit and activate a psr
source when intel_psr is already enabled.
- intel_psr_pause(): Pause current PSR. It deactivates current psr state.
- intel_psr_resume(): Resume paused PSR. It activates paused psr state.
v2: Address Jose's review comment.
- Remove unneeded changes around the intel_psr_enable().
- Add intel_psr_post_exit() which processes waiting until PSR is idle
and WA for SelectiveFetch.
v3: Address Jose's review comment.
- Rename intel_psr_post_exit() to intel_psr_wait_exit_locked().
- Move WA_1408330847 to intel_psr_disable_locked()
- If the PSR is paused by an explicit intel_psr_paused() call, make the
intel_psr_flush() not to activate PSR.
v4: Address Jose's review comment.
- In order to avoid the scenario of PSR is not active but there is a
scheduled psr->work, it changes the check routine of intel_psr_pause()
for PSR's enablement from "psr->active" to "psr->enable".
