[PATCH 0/5] Implement support for drm properties "GAMMA_LUT" and "CTM"

[Matheus Santana]

Hi Harsha,

I am unable to run the tests you introduced. Tests execution gets stuck
after reporting success for surface-global-test.

Is it necessary building weston against any newer libraries versions for
running the new tests?


Thanks,
Matheus
