Subject: [PATCH 114/432] 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.
