Subject: [Intel-gfx] [PATCH 0/2] Expose crtc dither state and connector max bpc via debugfs
Date: Tue, 21 Jul 2020 01:11:25 +0530	[thread overview]
Message-ID: <20200720194127.24750-1-bhanuprakash.modem@intel.com> (raw)

[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
