7a1c5c6753 drm/amdkfd: enable cooperative groups for gfx11
MES can concurrently schedule queues on the device that require
exclusive device access if marked exclusively_scheduled without the
requirement of GWS.  Similar to the F32 HWS, MES will manage
quality of service for these queues.
Use this for cooperative groups since cooperative groups are device
occupancy limited.

Since some GFX11 devices can only be debugged with partial CUs, do not
allow the debugging of cooperative groups on these devices as the CU
occupancy limit will change on attach.

In addition, zero initialize the MES add queue submission vector for MES
initialization tests as we do not want these to be cooperative
dispatches.

83f24a8f05 drm/amdgpu: set sw state to gfxoff after SR-IOV reset
[Why]
Current SR-IOV will not set GC to off state, while it is a real
GC hard reset. Whthout GFX off flag, driver may do gfxhub invalidation
before firmware load and gfxhub gart enable. This operation may cause
CP to become busy because GC is not in the right state for invalidation.

[How]
Add a function for SR-IOV to clean up some sw state before recover. Set
adev->gfx.is_poweron to false to prevent gfxhub invalidation before gfx
firmware autoload complete.

fff7b95a50 drm/amd/display: Fix race condition when turning off an output alone
[Why]
When 2 threads are doing commit_tail parallelly, one thread could
commit new streams to dc state but another thread remove it from dc
right away.

[How]
If we don't have new dm state change from commit_check, then we should
not call dc_commit_streams() in commit_tail. A new function
amdgpu_dm_commit_streams() is introduced to refator dc_commit_stream()
adjacent code and fix this issue.

c4ba2b50f2 drm/amd/display: add additional refresh rate conditions for SubVP cases
[Why]
Want to further constrain these refresh rate conditions for SubVP:
- SubVP + SubVP: either both <= 120Hz or both between 120-165Hz
- SubVP + DRR: SubVP <= 120Hz
- SubVP + VBlank: SubVP <= 120Hz

[How]
Add constraints in subvp_subvp_admissable(),
dcn32_subvp_drr_admissable() and dcn32_subvp_vblank_admissable()

c99fcb02bc drm/amd/display: refine to decide the verified link setting
[WHY]
We return false by default when link training fail at link loss.
It will cause we get a fail verified link caps directly.

[HOW]
Record the highest verified link caps. Use the recorded value as
the verified link caps if it is not successful in the last attempt
to avoid to use the lowest link setting.
