I think intel_update_watermarks needs to be fixed to take a crtc_state and whether pre/post commit is used.

Wouldn't it be better to fix intel_wm_need_update() instead if > returns true in that case? If visible is changed wm_changed = true is always set. It would go through the (turn_on || turn_off) case. I guess checking was_visible || visible is overkill, and could be changed to just visible && intel_wm_need_update(plane, plane_state).

What I meant is that I find odd that intel_wm_need_update() returns true when both was_visible and visible is false. Since that function is supposed to compare two plane states and tell us if a wm update is needed, I'd rather add the visible check there.

Since that function is supposed to > compare two plane states and tell us if a wm update is needed, I'd rather add > the visible check there. This could be fixed there. if (visible != was_visible) return true; if (!visible) return false; and then remove the fb checks.

This removes pre/post_wm_update from intel_crtc->atomic, and creates atomic state for it in intel_crtc. Changes since v1: - Rebase on top of wm changes. Changes since v2: - Split disable_cxsr into a separate patch.
