From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
MTL seems very good at racing the cursor mailbox updates against
the vblank, causing things to not latch for long enough to cause
GTT faults. Attempt to hook up vblank evasions into the legacy
cursor path to avoid this.
Also revert a dangerous wm/ddb change related to cursors.
Ville Syrjälä (9):
drm/i915: Decouple intel_crtc_vblank_evade_scanlines() from atomic
commits
drm/i915: Reorder drm_vblank_put() vs. need_vlv_dsi_wa
drm/i915: Introduce struct intel_vblank_evade_ctx
drm/i915: Include need_vlv_dsi_wa in intel_vblank_evade_ctx
drm/i915: Extract intel_vblank_evade()
drm/i915: Move the min/max scanline sanity check into
intel_vblank_evade()
drm/i915: Move intel_vblank_evade() & co. into intel_vblank.c
drm/i915: Perform vblank evasion around legacy cursor updates
Revert "drm/i915/xe2lpd: Treat cursor plane as regular plane for DDB
allocation"
