  back the deadlock until I can figure out what should be done properly.
  There was a scheduler regression vs amdgpu which was reported in a few
  places and is now fixed. There was an i915 vs simpledrm problem
  resulting in black screens, that is reverted also.

got an idea to fix it by offloading to a workqueue in a different

The FORCE_STOP_STATE bit is unsuitable to force the DSI link into LP-11
mode. It seems the bridge internally queues DSI packets and when the
FORCE_STOP_STATE bit is cleared, they are sent in close succession
without any useful timing (this also means that the DSI lanes won't go
into LP-11 mode). The length of this gibberish varies between 1ms and
5ms. This sometimes breaks an attached bridge (TI SN65DSI84 in this
case). In our case, the bridge will fail in about 1 per 500 reboots.

The FORCE_STOP_STATE handling was introduced to have the DSI lanes in
LP-11 state during the .pre_enable phase. But as it turns out, none of
this is needed at all. Between samsung_dsim_init() and
samsung_dsim_set_display_enable() the lanes are already in LP-11 mode.
The code as it was before commit 20c82768 ("drm: bridge:
samsung-dsim: Fix init during host transfer") and 0c14d313 ("drm:
bridge: samsung-dsim: Fix i.MX8M enable flow to meet spec") was correct
in this regard.

This patch basically reverts both commits. It was tested on an i.MX8M
SoC with an SN65DSI84 bridge. The signals were probed and the DSI
packets were decoded during initialization and link start-up. After this
patch the first DSI packet on the link is a VSYNC packet and the timing
is correct.

Command mode between .pre_enable and .enable was also briefly tested by
a quick hack. There was no DSI link partner which would have responded,
but it was made sure the DSI packet was send on the link. As a side
note, the command mode seems to just work in HS mode. I couldn't find
that the bridge will handle commands in LP mode.

All entities must be drained in the DRM scheduler run job worker to
avoid the following case. An entity found that is ready, no job found
ready on entity, and run job worker goes idle with other entities + jobs
ready. Draining all ready entities (i.e. loop over all ready entities)
in the run job worker ensures all job that are ready will be scheduled.

Add a new helper, bch2_hash_lookup_in_snapshot(), for when we're not
operating in a subvolume and already have a snapshot ID, and then use it
in lookup_lostfound() -> __lookup_dirent().

This is a bugfix - lookup_lostfound() doesn't take a subvolume ID, we
were passing a nonsense subvolume ID before, and don't have one to pass
since we may be operating in an interior snapshot node that doesn't have
a subvolume ID.

[Why]
With IPS enabled a system hangs once PSR is active.
PSR active triggers transition to IPS2 state.
While in IPS2 an access to dcn registers results in hard hang.
Existing check doesn't cover for PSR sequence.

[How]
Safeguard register access by disabling idle optimization in atomic commit
and crtc scanout. It will be re-enabled on next vblank.

[Why & How]
Add regkey to block video playback in IPS2 by default

Allow idle optimizations in the same spot we allow Replay for
video playback usecases.

Avoid sending it when there's an external display connected by
modifying the allow idle checks to check for active non-eDP screens.

This needs to be set to 1 to avoid a potential deadlock in
the GC 10.x and newer.  On GC 9.x and older, this needs
to be set to 0. This can lead to hangs in some mixed
graphics and compute workloads. Updated firmware is also
required for AQL.

This allows kernel mapped pages like the PDB and PTB to be
read via the iomem debugfs when there is no vram in the system.
