Message

Manna, Animesh Sept. 8, 2021, 9:15 a.m. UTC

Panel Replay is a power saving feature for DP 2.0 monitor and similar
to PSR on EDP.

These patches are basic enablement patches and reused psr
framework to add panel replay related new changes which
may need further fine tuning to fill the gap if there is any.

Note: The patches are not tested due to unavailability of monitor

  drm/i915/panelreplay: Feature flag added for panel replay
  drm/i915/panelreplay: Initializaton and compute config for panel
