[Intel-gfx] [PATCH 0/2] Expose crtc dither state and connector max bpc via debugfs

[Intel-gfx] [PATCH 0/2] Expose crtc dither state and connector max bpc via debugfs

[Bhanuprakash Modem]

[why]
It's useful to know the max supported panel BPC and PIPE dither state
for IGT testing.

[how]
* Expose the connector max supported BPC for the panel via a debugfs file on the
  connector, "output_bpc".
  Example: cat /sys/kernel/debug/dri/0/DP-1/output_bpc

* Expose the dithering state for the crtc via a debugfs file "dither".
  Example: cat /sys/kernel/debug/dri/0/crtc-0/dither

Test-with: 20200720165011.23918-1-bhanuprakash.modem@intel.com

[Intel-gfx] [PATCH 1/2] i915/debug: Expose crtc dither state via debugfs

[Bhanuprakash Modem]

[Why]
It's useful to know the dithering state for IGT testing.

[How]
Expose the dithering state for the crtc via a debugfs file "dither".

Example usage: cat /sys/kernel/debug/dri/0/crtc-0/dither
