+Subject: [PATCH 4/7] compositor-drm: Gracefully handle vblank and flip invalid
+ timestamps
+X-NVConfidentiality: public
+
+Instant query for vblank timestamp may always fail, resulting in
+never scheduling a full repaint in drm_output_start_repaint_loop().
+
+Additionally, timestamp provided in page_flip_handler() may also be
+invalid.
+
+This change makes both drm_output_start_repaint_loop() and
+page_flip_handler() to schedule a full repaint in any of the
+situations above.
