[Intel-gfx] [PATCH 00/13] drm/i915: Load LUTs with DSB

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Restore DSB usage for lodaing the LUTs, and do so
properly during vblank to avoid tearing. And also
included are some improvements to aid in analyzing
DSB issues.

There is one undocumented (afaik) hw issue with
the legacy LUT that I still need to report to the
hw folks. But I have already included what seems
like an effective workaround.

Ville Syrjälä (13):
  drm/i915/dsb: Define more DSB registers
  drm/i915/dsb: Pimp debug/error prints
  drm/i915/dsb: Split intel_dsb_wait() from intel_dsb_commit()
  drm/i915/dsb: Introduce intel_dsb_finish()
  drm/i915/dsb: Dump the DSB command buffer when DSB fails
  drm/i915/dsb: Allow vblank synchronized DSB execution
  drm/i915/dsb: Nuke the DSB debug
  drm/i915/dsb: Skip DSB command buffer setup if we have no LUTs
  drm/i915/dsb: Don't use DSB to load the LUTs during full modeset
  drm/i915/dsb: Load LUTs using the DSB during vblank
  drm/i915/dsb: Write each legacy LUT entry twice with DSB
  drm/i915/dsb: Load LUTs with the DSB
  drm/i915: Do state check for color management changes
