I ran the new experiment exactly as you described, using a DP->HDMI cable. Unfortunately, the problem is still reproducible. The output of intel_watermark is here: <a href="https://bugs.freedesktop.org/attachment.cgi?id=127557">https://bugs.freedesktop.org/attachment.cgi?id=127557</a>. The output of "intel_reg dump --all" is here: <a href="https://bugs.freedesktop.org/attachment.cgi?id=127558">https://bugs.freedesktop.org/attachment.cgi?id=127558</a>. These captured outputs will show that the new experiment is using port B/pipe B. Just for the record, the experiment was done on a BSW RVP using drm-intel-nightly without any of the changes that you've previously recommended.</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> </ul> </body> </html>
