[Description]
- Single 4K60 playing YUV420 MPO video blocks P-State because
the required VRatio for prefetch is too high (luma plane for
YUV420 is 1bpe, so swath height is 16 and prefetch requires
more lines)
- Allow max vratio per plane to be 7.9 for single display YUV420
MPO video cases
- Ensure that global vratio prefetch (i.e. total prefetch BW vs.
total active bandwidth) does not excited 4.0

[Why]
DOMAIN power gating control is now required to be done via firmware
due to interlock with other power features. This is to avoid
intermittent issues in the LB memories.
[How]
If the firmware supports the command then use the new firmware as
the sequence can avoid potential display corruption issues.
The command will be ignored on firmware that does not support DOMAIN
power control and the pipes will remain always on - frequent PG cycling
can cause the issue to occur on the old sequence, so we should avoid it.

When xnack is on user space can use svm page restore to set a vm range without
setup it first, then use regular api to register. Currently kfd api and svm are
not interoperable. We already have check on that, but for user buffer the mapping
address is not same as buffer cpu virtual address. Add checking on that to
avoid error propagate to hmm.

This test depends on <linux/user_events.h> exported in uapi
The following commit removed user_events.h out of uapi:
commit 5cfff569ca ("tracing: Move user_events.h temporarily out
of include/uapi")
This test will not compile until user_events.h is added back to uapi.

Since commit ee6d3dd4ed ("driver core: make kobj_type constant.")
the driver core allows the usage of const struct kobj_type.
Take advantage of this to constify the structure definition to prevent
modification at runtime.

Flushing system-wide workqueues is dangerous and will be forbidden.
Use a local workqueue in dm-mpath.c, dm-raid1.c, and dm-stripe.c.

Commit acfe0ad74d ("dm: allocate a special workqueue for deferred
device removal") switched from using system workqueue to a single
workqueue local to DM. But it didn't eliminate the call to
flush_scheduled_work() that was introduced purely for the benefit of
deferred device removal with commit 2c140a246d ("dm: allow remove to
be deferred").
Since DM core uses its own workqueue (and queue_work) there is no need
to call flush_scheduled_work() from local_exit(). local_exit()'s
destroy_workqueue(deferred_remove_workqueue) handles flushing work
started with queue_work().
