I didn't mean to be pejorative, I thought there was something that could improve the situation on compiler side, and it seems I was not completely wrong, even if it takes non-trivial work. The shader was generated by virgl when visiting <a href="https://www.shadertoy.com/view/MlX3RH">https://www.shadertoy.com/view/MlX3RH</a>. It is problematic since virgl runs in the qemu mainloop, freezing the VM if something takes too long to complete. The obvious first thing to do is to move virgl in a seperate thread, but this is non-trivial too :) With the help of Dave Airlie (who wrote virgl), I'll see if we can address this in virgl guest-side or tgsi->shader code. Your analysis is very helpful, thanks again! Hopefully, this bug will help to improve the driver side too.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
