[Intel-gfx] [PATCH 0/2] Enable Darkscreen Feature

[Nemesa Garg]

The logic checks for any black screen at pipe level and
upon such detection prints error. Darkscreen compares the
pixels with the compare value(0x00 - black) for the detection
purpose. This feature can be enables/disabled through debugfs.


Nemesa Garg (2):
  drm/i915: Add Darkscreen registers and timer handler.
  drm/i915: Add the darkscreen debugfs under crtc
