[PATCH v2 0/1] drm/xe: Build PM into GuC CT layer

[Matthew Brost]

Take PM ref when a G2H is outstanding, drop when it is received.

To safely ensure we have PM ref when in the GuC CT layer, a PM ref needs
to be held when scheduler messages are pending too.

v2:
 - Add outer PM protections to xe_file_close (CI)
