I am having a hard time to get gsraytrace to run. I am not sure whether this is related to this bug or to PRIME issues, as in general, using the Radeon GPU is a bit unstable here. The instability manifests in not receiving any rendering output in the window and sometimes error messages ("radeon: The kernel rejected CS, see dmesg for more information."). I made two tests: FIRST TEST When trying to run the gsraytrace demo on the radeon, I did not receive visual output in the window; no rendering took place, the window contents were never written and were showing what was at that place on the screen before the window opened. The terminal suggested a frame rate of 1 FPS. No crash happened. I then tried to distinguish between PRIME failure and demo failure by opening a glxgears instance on the radeon gpu, which made the whole X11 freeze for a few seconds and afterwards both glxgears and the gsraytrace demo spammed the above error message. SECOND TEST This time, I started glxgears first to make sure that everything was set up properly, PRIME-wise. glxgears was running fine at a reasonable frame rate. Then I started the gsraytrace demo, which made the X11 freeze. (I then went to fetch some tea) Both programs were spamming the above error message when the GUI had unfreezed. At no point I ever saw visual output from the gsraytrace demo. As I said, I am not sure what of this is purely due to PRIME and what is caused by the bug this entry refers to. I just wanted to add my data here as it was requested for and I don’t think I will get better results on my own.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
