<div dir="ltr"><div>Hi,</div><div><br></div><div>some update from my side.</div><div><br></div>I updated the device now to mesa-git (revision 2412c4c81ea0488df865817a0de91ec46e359b72), wayland-protocols-1.9, wayland-1.13.91 and weston 2.99.91 <div>The problem still persists.</div><div><br></div><div>However i noticed in dmesg sporadic lines. I am uncertain if they are related to the problem.</div><div><br></div><div>The dmesg line is alloc_contig_range: [4e087, 4e088) PFNs busy</div><div><br></div><div>The message is always showing the same address. </div><div>When running weston-simple-egl the messages comes in a pack of 1-6 messages within half a second and then the next pack comes in about 1-5 seconds later. As soon as I stop weston-simple-egl the message disappears.</div><div>when running weston-simple-shm the same message comes in as well, but only 1-2 messages per second, with 1-2 seconds gaps. In contrast to weston-simple-egl the display of weston-simple-shm looks good.</div><div><br></div><div>Further glmark2 with drm-glesv2 backend is running visually fine on almost all tests (only exception i noticed was terrain, where it is complaining about shaders).</div><div><br></div><div>any clue where i should dig in to understand why the weston-simple-egl is distorted?</div><div><br></div><div>Best regards</div><div> Torsten</div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">2017-07-19 14:48 GMT+02:00 Torsten Sievers <span dir="ltr"><<a href="mailto:torstensievers@googlemail.com" target="_blank">torstensievers@googlemail.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><span style="font-size:12.8px">Hi everybody,</span><div style="font-size:12.8px"><br></div><div style="font-size:12.8px">i am fighting a bit with my Hummingboard2 at the moment.
