I can live without that for the moment. Respun the only use HW vblanks for the last frame and ran it through my accuracy tests, no misses so pushed: commit a76560107f7d97b80d47e90b46535a8aba273c32 Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>> Date: Wed Apr 6 09:23:05 2016 +0100 sna/present: Only use the HW vblank for the last frame If that doesn't stop the starvation issue, I have no idea. Looking through the logs, I haven't found a reason for the freeze. After the failed unflip, it looks to be rendering back into the Screen Pixmap and that appears to be on the scanout (i.e. all the updates should be visible).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
