[Intel-gfx] [PATCH 1/2] drm/i915: Swap ggtt_vma during legacy cursor update

[Maarten Lankhorst]

Xe is lacking the ability to re-use the ggtt_vma when updating cursor.
Instead of pinning from the new plane_state, move the ggtt_vma from
old_plane_state to new_plane_state.

[Intel-gfx] [PATCH 2/2] drm/i915: Handle legacy cursor update as normal update

[Maarten Lankhorst]

Move hw_done to cleanup, to ensure we only unpin cursor fb after we
received a flip event. This disables the legacy_cursor_update immediate
completion of flip_done events, and waits for flip_done before cleaning
up.

There are failures in CI due to the change, this causes device busy issue.

[Intel-gfx] [PATCH 2/2] drm/i915: Handle legacy cursor update as normal update

[Maarten Lankhorst]

Abuse the vblank worker to make the changes as small as possible. We
need a way to sync flip_done, but if we wait on flip_done, all async
tests start failing.

[Intel-gfx] [PATCH 2/2] drm/i915: Handle legacy cursor update as normal update

[Maarten Lankhorst]

From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

Abuse the vblank worker to make the changes as small as possible. We
need a way to sync flip_done, but if we wait on flip_done, all async
tests start failing.

Changes since v1:
- Prevent null deref when crtc is inactive.
