https://bugzilla.kernel.org/show_bug.cgi?id=90741 Bug ID: 90741 Summary: Radeon: System pauses on TAHITI Product: Drivers Version: 2.5 Kernel Version: 3.18.0 3.18.1 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: wielkiegie@xxxxxxxxx Regression: No The system freezes for 1-3 seconds from time to time. No message is shown in dmesg. Some of the programs report high display delays in their profiles (maybe glXSwapBuffers?). The pause is system-wide, probably due to whole-OpenGL stack (glamor). This seems to be a 3.18.x regression. The problem does not occur on 3.17.4. During normal usage the problem is very rare. However, it occurs very often while playing OpenGL games. For games like Minecraft, the pauses are less likely while not moving around. I believe that the game does not upload many buffers then. So the issue may be due to buffer management. I am using mesa from git, libdrm from git, xserver 1.16.2.901, xf86-video-ati 7.5. The problem occurs both with compositing enabled and disabled (kwin). -- 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
