The pipe has a special HDR mode with higher precision when only HDR planes are active. Let's use it. Curiously this fixes the kms_color gamma/degamma tests when using a HDR plane, which is always the case unless one hacks the test to use an SDR plane. If one does hack the test to use an SDR plane it does pass already. I have no actual explanation how the output after the gamma LUT can be different between the two modes. The way the tests are written should mean that the output should be identical between the solid color vs. the gradient. But clearly that somehow doesn't hold true for the HDR planes in non-HDR pipe mode. Anyways, as long as we stick to one type of plane the test should produce sensible results now. v2: s/HDR_MODE/HDR_MODE_PRECISION/ (Shashank) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190412183009.8237-2-ville.syrjala@linux.intel.com Reviewed-by: Uma Shankar <uma.shankar@intel.com> Tested-by: Uma Shankar <uma.shankar@intel.com> Reviewed-by: Shashank Sharma <shashank.sharma@intel.com>
