[RFC][PATCH 00/11] drm/i915/prefill: Introduce helpers for prefill latency calculations

[Ville Syrjala <ville.syrjala@linux.intel.com>]

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

Introduce intel_prefill and various accompanying helpers to do 
pipe prefill latency related stuff (vblank/guardband length
checks, and in the future reduced guardband length).

Still a bit rough in plaeces so tossing it out as more of
and RFC at this stage.

Ville Syrjälä (11):
  drm/i915: Reject modes with linetime > 64 usec
  drm/i915/cdclk: Add prefill helpers for CDCLK
  drm/i915/cdclk: Add intel_cdclk_min_cdclk_for_prefill()
  drm/i915/dsc: Add prefill helper for DSC
  drm/i915/scaler: Add scaler prefill helpers
  drm/i195/wm: Add WM0 prefill helpers
  drm/i915: Introduce intel_compute_global_watermarks_late()
  drm/i915/prefill: Introduce intel_prefill.c
  drm/i915/wm: Use intel_prefill
  drm/i915/prefill: Print the prefill details
  drm/i915/prefill: Also print out the worst case estimates
