Subject: [PATCH 0/3] drm/msm: kthread_worker conversion

From: Rob Clark <robdclark@...omium.org>

In particular, converting the async atomic commit (for cursor updates,
etc) to SCHED_FIFO kthread_worker helps with some cases where we
wouldn't manage to flush the updates within the 1ms-before-vblank
deadline resulting in fps drops when there is cursor movement.

Rob Clark (3):
  drm/msm/gpu: Convert retire/recover work to kthread_worker
  drm/msm/kms: Update msm_kms_init/destroy
  drm/msm/atomic: Convert to per-CRTC kthread_work
