Jack Zhang ef1c0cbcd1 drm/amd/amdgpu/sriov temporarily skip ras,dtm,hdcp for arcturus VF
Temporarily skip ras,dtm,hdcp initialize and terminate for arcturus VF
Currently the three features haven't been enabled at SRIOV, it would
trigger guest driver load fail with the bare-metal path of the three
features.

Mikita Lipski e3dd3aa8e0 drm/amd/display: Fix debugfs on MST connectors
[why]
Previous patch allowed to initialize debugfs entries on both MST
and SST connectors, but MST connectors get registered much later
which exposed an issue of debugfs entries being initialized in the
same folder.

[how]
Return SST debugfs entries' initialization back to where it was.
For MST connectors we should initialize debugfs entries in connector
register function after the connector is registered.

On some platforms (e.g. KBL) that do not support GuC submission, but
the user enabled the GuC communication (e.g for HuC authentication)
calling the GuC EXIT_S_STATE action results in lose of ability to
enter RC6. We can remove the GuC suspend/resume entirely as we do
not need to save the GuC submission status.

Add intel_guc_submission_is_enabled() function to determine if
GuC submission is active.

v2: Do not suspend/resume the GuC on platforms that do not support
    Guc Submission.
v3: Fix typo, move suspend logic to remove goto.
v4: Use intel_guc_submission_is_enabled() to check GuC submission
    status.
v5: No need to look at engine to determine if submission is enabled.

Chris Wilson a46bfdc83f drm/i915/gt: Wait for new requests in intel_gt_retire_requests()
Our callers fall into two categories, those passing timeout=0 who just
want to flush request retirements and those passing a timeout that need
to wait for submission completion (e.g. intel_gt_wait_for_idle()).
Currently, we only wait for a snapshot of timelines at the start of the
wait (but there was an expectation that new requests would cause timelines
to appear at the end). However, our callers, such as
intel_gt_wait_for_idle() before suspend, do require us to wait for the
power management requests emitted by retirement as well. If we don't,
then it takes an extra second or two for the background worker to flush
the queue and mark the GT as idle.

fbdev uses the physical address of our framebuffer for its fb_mmap()

Lionel Landwerlin 7e89d50855 drm/i915/perf: don't forget noa wait after oa config
I'm observing incoherence metric values, changing from run to run.

It appears the patches introducing noa wait & reconfiguration from
command stream switched places in the series multiple times during the
review. This lead to the dependency of one onto the order to go
missing...

Bruce Chang 3e749f5199 drm/i915: Avoid atomic context for error capture
io_mapping_map_atomic/kmap_atomic are occasionally taken in error capture
(if there is no aperture preallocated for the use of error capture), but
the error capture and compression routines are now run in normal
context:

Imre Deak 5d77aa07bd drm/i915: Fix detection for a CMP-V PCH
According to internal documents I found for CMP PCHs the PCI ID 0xA3C1
belongs to a CMP-V chipset. Based on the same docs the programming of
the PCH is compatible with that of KBP. Fix up my previous wrong
assumption accordingly using the SPT programming which in turn is the
basis for KBP.

The original bug reporter verified that this is the correct PCH
identification (the only way we'll program valid DDC pin-pair values to
the GMBUS register) and the Windows team uses the same identification
(that is using the KBP programming model for this PCH).

I filed the necessary Bspec update requests (BSpec/33734).

Gerd Hoffmann 9786b65bc6 drm/ttm: fix mmap refcounting
When mapping ttm objects via drm_gem_ttm_mmap() helper
drm_gem_mmap_obj() will take an object reference.  That gets
never released due to ttm having its own reference counting.

Fix that by dropping the gem object reference once the ttm mmap
completed (and ttm refcount got bumped).

For that to work properly the drm_gem_object_get() call in
drm_gem_ttm_mmap() must be moved so it happens before calling
obj->funcs->mmap(), otherwise the gem refcount would go down
to zero.

In some circumstances the RC6 context can get corrupted. We can detect

The HW recovers from the corrupted state after a system suspend/resume
cycle, so detect the recovery and re-enable RC6 and runtime PM.
