During the work towards enabling exhaustive eviction using full
ww locking in TTM, Christian indicated that the path for the
drm_exec moving forward was to be a full drm_exec helper with
things like userptr validation rather than a WW transaction
abstraction. The idea was then briefly discussed to craft a
WW transaction helper and then subclass that with drm_exec
with the idea that the WW transaction helper could be used in
TTM for eviction and for other uses that didn't mandate a full
exec sequence.
Regardless whether that actually happens or not, this series
aims to clean up abuses of drm_exec internals in drivers
so that future development of drm_exec isn't blocked by
such driver usage.
Except for patch 3 which is a small cleanup only.
Thomas Hellström (5):
drm/exec: Remove the index parameter from
drm_exec_for_each_locked_obj[_reverse]
drm/msm: Remove abuse of drm_exec internals
drm/exec: Make the drm_exec_until_all_locked() macro more readable
drm/exec, drm/xe: Avoid abusing the drm_exec retry pointer
drm/exec, drm/xe, drm/amdgpu: Add an accessor for struct
drm_exec::ticket
