We were previously adding all the planes owned by the CRTC even when the ddb partitioning didn't change for them. As a consequence, a lot of functions were being called when we were just moving the cursor around the screen, such as skylake_update_primary_plane(). This was causing flickering on the primary plane when moving the cursor. I'm not 100% sure which operation caused the flickering, but we were writing to a lot of registers, so it could be any of these writes. With this patch, just moving the mouse won't add the primary plane to the commit since it won't trigger a change in DDB partitioning. v2: Use skl_ddb_entry_equal() (Lyude). v3: Change Reported-and-bisected-by: to Reported-by: for checkpatch Fixes: 05a76d3d ("drm/i915/skl: Ensure pipes with changed wms get added to the state") Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97888 Cc: Mike Lothian <mike@fireburn.co.uk> Cc: stable@vger.kernel.org Reported-by:
