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: [email protected]
ReportedBy: [email protected]
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.
