Bug #: 44422 Summary: periodic slowdowns in every 30sec Classification: Unclassified Product: Mesa Version: git Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: aaalmosss@gmail.com
Rendering slows down to crawl for <1sec every 30 secs. It affects everything: 3d applications, video playback, 2d drawing (e.g. kpatience), probably because of the compositing.
I suspect this is caused by r600g, because my other machine running the same distribution but r300g doesn't have this problem. Current 7.12-dev (git-2cd7e5b) seems to slow down less than 7.11, but the effect remains and it is very noticeable.

If it happens every 30 seconds, it may be your desktop environment polling the connectors on your video card to see what is connected. They shouldn't be doing that as the driver handles that internally and generates hotplug events automatically.

Hmmm... I haven't noticed there are so many call traces in dmesg. Disturbing.

I killed both, but the issue remains. How can I disable output polling in kde4?

You might try some of these instructions: http://linux-tipps.blogspot.com/2009/03/fixing-high-latency-with-kde4-displa... Alternatively, you could try starting just X (no desktop) in single user mode and see if you are still getting the issue.

--- Comment #8 from almos aaalmosss@gmail.com 2012-01-03 13:08:56 PST --- Now I experimented a bit and found the culprit: the dd-wrt control panel opened in firefox reloads itself every 30 seconds. It seems that page loading (or rendering?) is a real resource hog in firefox, even though this is not a slow machine (see (9) in rfc1925).
Closing as notourbug.
