[PATCH v2 13/14] drm/vc4: crtc: Fix out of order frames during asynchronous page flips

2022-06-10 Thread Maxime Ripard
When doing an asynchronous page flip (PAGE_FLIP ioctl with the DRM_MODE_PAGE_FLIP_ASYNC flag set), the current code waits for the possible GPU buffer being rendered through a call to vc4_queue_seqno_cb(). On the BCM2835-37, the GPU driver is part of the vc4 driver and that function is defined in
