From: Ville Syrjälä Date: Thu, 13 Apr 2023 16:49:11 +0000 (+0300) Subject: drm/i915: Expose crtc CTM property on ilk/snb X-Git-Tag: v6.5-rc1~28^2~14^2~27 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=d9ce4e430790ba4f45e5febd7b4bd87b0f23563e;p=linux-block.git drm/i915: Expose crtc CTM property on ilk/snb The ilk/snb code is internally fully capable of handling the CTM property, so expose it. Note that we still choose not to expose DEGAMMA_LUT though. The hardware is capable if degamma or gamma, but not both simultanously due to lack of the split gamma mode. Exposing both LUTs might encourage userspace to try enabling both at the same time.
