See previous cover letter for detailed explanation of series: https://lists.freedesktop.org/archives/intel-gfx/2016-April/091293.html Key changes since the last spin (mostly based on Maarten's feedback): - During DDB/WM calculation, avoid grabbing extra plane_state's for the planes that aren't being modified by the transaction. We do this by caching data rates and minimum block sizes in the crtc_state so that they can be re-used for subsequent transactions if the pipe's DDB size isn't changing. - Only use ->active_crtcs when we're sure we're not racing with anything that could update it. - Drop the pstate_for_cstate_plane() helper and describe more clearly in comments how/why the code may need to change in the future if we start supporting multiple pending commits.
