By always keeping track of the last commit in plane_state, we know whether there is an active update on the plane or not. With that information we can reject the fast update, and force the slowpath to be used as was originally intended. We cannot use plane_state->crtc->state here, because this only mentions the most recent commit for the crtc, but not the planes that were part of it. We specifically care about what the last commit involving this plane is, which can only be tracked with a pointer in the plane state. Changes since v1: - Clean up the whole function here, instead of partially earlier. - Add mention in the commit message why we need commit in plane_state. - Swap plane->state in intel_legacy_cursor_update, instead of reassigning all variables. With this commit We know that the cursor is not part of any active commits so this hack can be removed.
