drm/amdgpu: Enable GFXOFF for Compute on GFX11
On GFX version 11, GFXOFF was disabled due to a MES KIQ firmware
issue, which has since been fixed after version 64.
This patch only re-enables GFXOFF for GFX version 11 if the GPU's
MES KIQ firmware version is newer than version 64.
V2: Keep GFXOFF disabled on GFX11 if MES KIQ is below version 64.
V3: Add parentheses to avoid GCC warning for parentheses:
"suggest parentheses around comparison in operand of ‘&’"
V4: Remove "V3" from commit title
V5: Change commit description and insert 'Acked-by'

drm/i915/dp: Fix the PSR debugfs entries wrt. MST connectors
MST connectors don't have a static attached encoder, as their encoder
can change depending on the pipe they use; so the encoder for an MST
connector can't be retrieved using intel_dp_attached_encoder() (which
may return NULL for MST). Most of the PSR debugfs entries depend on a
static connector -> encoder mapping which is only true for eDP and SST
DP connectors and not for MST. These debugfs entries were enabled for
MST connectors as well recently to provide PR information for them, but
handling MST connectors needs more changes.
Fix this by not adding for now the PSR entries on MST connectors. To
make things more uniform add the entries for SST connectors on all
platforms, not just on platforms supporting DP2.0.
v2:
- Keep adding the entries for SST connectors. (Jouni)
- Add a TODO: comment for MST support.

drm/i915/display: Fix C20 pll selection for state verification
Add pll selection check for C20 as well as
clock state verification0. We have been relying
on sw state to select A or B pll's. This is incorrect
as the hw might see this selection differently. This
patch fixes this shortcoming by reading pll selection
for both sw and hw states and compares if these two
selections match.

[WHY]
When usb4 bandwidth allocation mode is enabled, driver need to request
bandwidth from connection manager. For mst link, the requested
bandwidth should be big enough for all remote streams.
[HOW]
- If mst link, the requested bandwidth should be the sum of all mst
streams bandwidth added with dp MTPH overhead.
- Allocate/deallcate usb4 bandwidth when setting dpms on/off.
- When doing display mode validation, driver also need to consider total

[Why]
If an OPP is used for a different OPTC without first being disconnected

[How]
Disconnect OPPs from OPTC for phantom pipes before disabling OTG master.
Also move the disconnection to before the OTG master disable, since the

I believe this cannot really lead to a deadlock in practice, because
svm_range_evict_svm_bo_worker only takes the mmap_read_lock if the BO
refcount is non-0. That means it's impossible that svm_range_bo_release
is running concurrently. However, there is no good way to annotate this.
To avoid the problem, take a BO reference in
svm_range_schedule_evict_svm_bo instead of in the worker. That way it's
impossible for a BO to get freed while eviction work is pending and the
cancel_work_sync call in svm_range_bo_release can be eliminated.
v2: Use svm_bo_ref_unless_zero and explained why that's safe. Also
removed redundant checks that are already done in
amdkfd_fence_enable_signaling.
