Bug ID: 86832 Summary: [dota2][si] freezes up to 3 seconds when many/big display effects happen Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: critical Priority: medium Component: DRM/Radeon Assignee: dri-devel@lists.freedesktop.org Reporter: sylvain.bertrand@gmail.com

up-to-date fedora x86_64 rawhide with no-debug kernel. Radeon R9 280X.

dota2 will most of the time freeze up to several seconds when many/big display effects happen.

This is critical since while in a [team] fight where those effects happen, the freeze time will make you lose the fight most of the time.

--- Comment #5 from Michel Dänzer michel@daenzer.net --- Any chance you could try a kernel from Alex Deucher (agd5f)'s drm-next-3.19 branch?

--- Comment #6 from Sylvain BERTRAND sylvain.bertrand@gmail.com --- Not really. Last time I tried dev stuff on fedora rawhide, it was complex and heavy (massive kludge), and at the end the system refused to boot up (systemd sh*t). I still don't have my custom "live"/mobile gnu/linux distro ready (need to code a few more components).

--- Comment #8 from Sylvain BERTRAND sylvain.bertrand@gmail.com --- Ok... after several hours, I was able to pinpoint proper kernel features to be allowed by the Grand Master Of Kludge, systemd, and its minions, rtkit and fedora configuration, to run! I have a very minimal kernel to avoid, as much as I can, interference from other components. I'll start testing from now.

Notice UVD and DPM winning in the provided dmesg. I do provide the kernel config file for reference too.

It contains all the required features to please systemd, rtkit and other fedora configuration kludge.
