https://bugzilla.kernel.org/show_bug.cgi?id=65761 --- Comment #23 from Christoph Haag <haagch.christoph@xxxxxxxxxxxxxx> --- Created attachment 123891 --> https://bugzilla.kernel.org/attachment.cgi?id=123891&action=edit quitting steam after some time So maybe radeon-profile shows garbage, but in the steam client I have found one of the worse offenders. It doesn't happen always, but often, especially after quitting a game I think, but maybe it's just after some time. When "it" happens, the fan runs one "level" higher than usual and after I noticed it I started radeon-profile and it showed what you see in the attached screenshot. As soon as I quit steam, the temperature (read by lm_sensors I think) drops quickly, the voltages and frequencies (read from debugfs I think) are (mostly) stopping to being at the top all the time and only exhibit the spikes from my last comment, but most importantly the fan quickly drops to the usual behavior of switching between the lowest level and off instead of running on the "second lowest level" all the time like when steam was running. I have had a quick look at the xf86-video-ati but I'm not sure what I'm looking for: Is there one single function or so I can set a break point on that would definitely tell me whether the radeon gpu is ordered to wake up/render something? I'd be happy to try it on the kernel side too, but maybe there's a chance to get a backtrace on the X side to see where it is coming from - all given that it actually happens like I naively imagine. But I don't see anything else: According to LIBGL_DEBUG=verbose steam doesn't open the radeonsi driver, but yet sometimes manages to keep the fan of the radeon gpu running on higher rpm. I would be happy to also test patches against whatever that could add debug logging to point out what the radeon gpu is doing and why. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
