Adding set_blob ioctl to DRM

alternatives do I have inside drm to set multiple parameters otherwise? (other than Exynos specific ioctls) Please guide me. Regards, Rahul Sharma.

Adding set_blob ioctl to DRM

gree with you. I will define these as generic structures which are complete sets of parameters, required by standard color algorithms. Something like this: Color Reproduction: - R[r,g,b], G[r,g,b], B[r,g,b] - Cyan[r,g,b], Magenta[r,g,b], Yellow[r,g,b] - White[r,g,b] - B
