Will commit, but looks like Ville made a comment about double buffering.
Everything in intel_pipe_update_start depends on double buffering, so if the lut isn't then it probably has to be done either before or afterwards. Not sure which, either way would produce some flickering. :(
It should be done from a vblank worker. Unfortunately we still don't
have those, so either before or after is fine, and it'll result in
exactly the same amount of flickering as the current code.
Should I take from this that the patch is fine for now as we don't have
vblank workers yet?
I can resend another version with a TODO comment.
Thanks,
