[PATCH 00/14] drm/i915: M/N cleanup

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

Start cleaning up the M/N stuff. Couple of eventual goals:
- fix/enhance DRRS (it's currently in kind of poor state)
- move towards eliminating any RMW stuff from the atomic
  commit so that we can start playing around with using
  DSB for it, and the DRRS PIPECONF RMWs are a bit in the
  way so need to think of a way to avoid them, or at least
  make them not race with the atomic commit.

Ville Syrjälä (14):
  drm/i915: Extract intel_{get,set}_m_n()
  drm/i915: Clean up M/N register defines
  drm/i915: s/gmch_{m,n}/data_{m,n}/
  drm/i915: Move drrs hardware bit frobbing to small helpers
  drm/i915: Make M/N set/get a bit more direct
  drm/i915: Move PCH transcoder M/N setup into the PCH code
  drm/i915: Move M/N setup to a more logical place on ddi platforms
  drm/i915: Extract {i9xx,ilk}_configure_cpu_transcoder()
  drm/i915: Add fdi_m2_n2
  drm/i915: Program FDI RX TUSIZE2
  drm/i915: Dump dp_m2_n2 always
  drm/i915: Extract can_enable_drrs()
  drm/i915: Set DP M2/N2 equal to M1/N1 when not doing DRRS
  drm/i915: Always check dp_m2_n2 on pre-bdw
