Summary: r600g glitching in tunnel demo Product: Mesa Version: git Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: lists@andyfurniss.entadsl.com
Running xserver 1.9,gits ddx/mesa/libdrm and d-r-t on rv790 with wait vline/dri2 vsync disabled.
Since the mesa commit 3d45d57044507506ca834a4bf983422549c5240a r600g: TODO domain management
I get quite severe 1/2 second glitches running the mesa demo tunnel, it seems that rather than a regression this commit causes an amplification of a pre existing, but low level issue.
The glitches do not show in most games, sauerbraten will show it.
They are worse if I have my card set to high perf.
Running latencytop + tunnel often shows nothing, but will sometimes catch a 1/2 second event in radeon_fence_wait, and more rarely 300ms in radeon_cs_ioctl.
r600c does not glitch.
