Summary: r600 glamor high X cpu usage and lag on some gtk2
applications
Severity: normal
Classification: Unclassified
OS: Linux (All)
Reporter: aleks0...@gmail.com
Hardware: x86-64 (AMD64)
Status: NEW
Version: 9.2
Component: Drivers/DRI/R600
Product: Mesa
Hi,
I try to run my Archlinux with Glamor acceleration on my RV670 card (AGP), but
X server takes a (slight) high CPU usage (~15-18%, on Opteron 185 2600 MHz
S939) when i activate it with xorg.conf. Revert back to EXA falls X CPU usage
to < 5-6%. Moreover, with Glamor, some gtk2 applications have strong lag for
example when i click on a menu in the menu bar, like Thunar, or, when i switch
tabs of web pages in Midori. This is strange because i have no problem when i
scroll web pages, all run smoothly (better performance than EXA). On other gtk2
applications i haven't this problem. Also, with Glamor enabled the XFCE logout
dialog takes about a minute to be shown. Neither Xorg.log nor dmesg show
anything about any bug (memory leak or other). X has never crashed.
Here some informations :
glxinfo > OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD RV670
OpenGL core profile version string: 3.1 (Core Profile) Mesa 9.2.1
OpenGL core profile shading language version string: 1.40
OpenGL core profile context flags: (none)
