Summary: Sync to vblank does not work on X1300 Mobility
Product: Mesa
Version: unspecified
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/DRI/Radeon
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: cnspe...@physik.uni-wuerzburg.de
When I enable any vsync mode in driconf, glxgears takes some seconds to display
anything besides a black window, then garbage, and after that, it renders
correctly with a very slow framerate (<1 fps). Other 3D applications display
the same behaviour. If I enable interrupts instead of sleeps, I additionally
get the following message:
do_wait: drmWaitVBlank returned -1
This is mesa 7.3 (there was no option for that one above, so I set
unspecified). I am using xorg-server 1.5.3 on gentoo together with the radeon
driver 6.12.0. The machine is a thinkpad T60/Core duo (no Core2, so 32 bit)
with a X1300 mobility radeon.
I have attached xorg.conf and Xorg.0.log; please tell me if you need any
further info.
