You could try with virglrenderer from git, and if it still fails, report a bug to the virgl mailing list. Regarding benchmarks, those aren't so great if you compare them with the host today (especially "artificial" benchmarks like glmark2), I would say it's between 30-50% of host, so there is room for improvements. thanks </pre> </blockquote> yes, I used the latest virglrender from git. so Cc:<a href="mailto:virglrenderer-devel@lists.freedesktop.org">virglrenderer-devel@lists.freedesktop.org</a> <pre class="moz-signature" cols="72">-- Sincerely, Chen Fan</pre> </body> </html>
