Meanwhile, I did the following experiment which might indicate that the problem is isolated to pipe C. I closed the lid so that the primary display would go away while the external HDMI display would continue with the video playback. This is basically dock mode. Yet, the problem is still reproducible. The output of intel_watermark is here: <a href="https://bugs.freedesktop.org/attachment.cgi?id=127107">https://bugs.freedesktop.org/attachment.cgi?id=127107</a> This experiment was done using drm-intel-nightly with all of the suggestions you have recommended so far (DDL=0, latency=45us, and cursor WM=63). However, the experiment was done on a production device on which dock mode was functional. I was not able to "close the lid" on the BSW RVP. I found the switch on the BSW RVP for "closing the lid", but dock mode wasn't working for some reason. What do you think of this dock-mode experiment? Do you think it's still worthwhile to continue with the pipe-B experiment?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
