Subject: [Intel-gfx] [PATCH v2 0/9] drm/i915: Fix bandwith related cdclk calculations
Date: Thu,  3 Mar 2022 21:11:58 +0200	[thread overview]
Message-ID: <20220303191207.27931-1-ville.syrjala@linux.intel.com> (raw)

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

Fix up the dbuf bandwidth cdclk calculations to match the spec,
and also implement the cdclk based pipe max bandwidth limit.

TODO: intel_bw contains two orthogonal things (qgv vs. cdclk).
      We should probably just split it into two parts to life
      less confusing. But as usual naming is hard so I didn't
      go for that yet...

v2: Rebased due to the async flip wm0/ddb stuff

Ville Syrjälä (9):
  drm/i915: Tweak plane ddb allocation tracking
  drm/i915: Split plane data_rate into data_rate+data_rate_y
  drm/i915: Pre-calculate plane relative data rate
  drm/i915: Remove total[] and uv_total[] from ddb allocation
  drm/i915: Nuke intel_bw_calc_min_cdclk()
  drm/i915: Round up when calculating display bandwidth requirements
  drm/i915: Properly write lock bw_state when it changes
  drm/i915: Fix DBUF bandwidth vs. cdclk handling
  drm/i915: Add "maximum pipe read bandwidth" checks
