-Subject: drm/vc4: Don't wait for vblank when updating the cursor
-
-Commonly used desktop environments such as xfce4 and gnome
-on debian sid can flood the graphics drivers with cursor
-updates.  Because the current implementation is waiting
-for a vblank between cursor updates, this will cause the
-display to hang for a long time since a typical refresh
-rate is only 60Hz.
-
-This is unnecessary and unexpected by user mode software,
-so simply swap out the cursor frame buffer without waiting.
