* drm/amd/display: Use kvzalloc for potentially large allocationsMichel Dänzer2018-05-151-7/+7
| | | | | | | | | Allocating up to 32 physically contiguous pages can easily fail (and has failed for me), and isn't necessary anyway. Reviewed-by: Harry Wentland <harry.wentland@amd.com> Signed-off-by: Michel Dänzer <michel.daenzer@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
* drm/amd/display: Have DC manage its own allocation of gammaAnthony Koo2018-05-151-1/+7
| | | | | | | | | | | | | | Creating plane will also allocate gamma and input TF Creating stream will also allocate outputTF Fix issue with gamma not applied OS may call SetGamma before surface committed, so need to store in target and apply later.
