Subject: [PATCH 0/3] drm/vc4: Atomic color management support
Date: Fri, 16 Mar 2018 22:50:56 +0100 [thread overview]
Message-ID: <1521237059-37117-1-git-send-email-stschake@gmail.com> (raw)
This series adds support for the gamma and CTM properties to VC4.
Patches 2 and 3 need the register definitions from here:
https://patchwork.freedesktop.org/patch/207863/
The CTM support is somewhat limited in that we can only enable it for one
CRTC at a time and coefficients are S0.9 in hardware. The latter still
seem good enough for the various color corrections Android offers.
Stefan Schake (3):
drm/vc4: Expose gamma as atomic property
drm/vc4: Add color transformation matrix (CTM) support
drm/vc4: Restrict active CTM to one CRTC
