From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
Use the DSB to perform simple plane/color management commits.
Anything more complicatd (modesets and fastsets) are still
punted to the mmio path.
Also DSB won't be used when any of these are in use:
- scalers (scaler code needs more work)
- VRR (need to figure out a race free commit completion scheme)
- PSR (zero thoughts given for PSR interactions so far)
- async flips (no real though given here either)
Ville Syrjälä (13):
drm/i915/dsb: Avoid reads of the DSB buffer for indexed register
writes
drm/i915: Prepare clear color before wait_for_dependencies()
drm/i915/dsb: Generate the DSB buffer in commit_tail()
drm/i915/dsb: Enable programmable DSB interrupt
drm/i915/dsb: Introduce intel_dsb_vblank_evade()
drm/i915/dsb: Introduce intel_dsb_wait_usec()
drm/i915/dsb: Introduce intel_dsb_wait_vblanks()
drm/i915: Introduce intel_scanlines_to_usecs()
drm/i915/dsb: Introduce intel_dsb_wait_vblank_delay()
drm/i915: Extract intel_crtc_prepare_vblank_event()
drm/i915: Plumb 'dsb' all way to the plane hooks
drm/i915: Plumb 'dsb' all way to the color commit hooks
drm/i915/dsb: Use DSB for plane/color management updates
