-Subject: [PATCH] drm/vc4: Fix sending of page flip completion events in FKMS
- mode.
-
-In the rewrite of vc4_crtc.c for fkms, I dropped the part of the
-CRTC's atomic flush handler that moved the completion event from the
-proposed atomic state change to the CRTC's current state. That meant
-that when full screen pageflipping happened (glxgears -fullscreen in
-X, compton, por weston), the app would end up blocked firever waiting
-to draw its next frame.
