I read Michael's article on the state of 3D/R500 in the OSS radeon driver. It mentions frame rate dips in some games, which I have not experienced. However, I do get consistent hard lockups whenever using openarena or compiz (it probably affects every 3D app but these are the only 2 things I've been testing with). The lockups happen consistently to the point where I can't use compiz for more than an hour or so (but often it only takes a few minutes of usage) before dragging a window locks up the whole PC. It seems like something is still seriously wrong.
All of my X libs/programs are up to date with their respective master GIT repositories (I built everything on May 30).
Is this a known issue? Is anybody else experiencing this issue? In the GIT commit log it's mentioned that the R500 3D support is now comparable with the R300 support. Is this happening to R300 users too?
Also, what can I do so that I can capture useful information when these hard lockups do occur?
I remain committed to helping this driver in any way I can and that's why I bring this issue to the table.
Unfortunately I have been experiencing the same, but only using xserver from git (I need it because I'm on x86_64).
I don't use compiz, but kde4 instead: when I click to activate composite effects my pc hangs immediately, and I have no control over it anymore.
Also, it hangs the same way when logging out from a kde4 session (no effects enabled). The thing is... it's not completely frozen, because the mouse cursor in kdm keeps blinking!! But I still can't shut it down properly...
And finally it randomly froze after an hour I was watching a movie with mplayer.
Now, I have tried disabling the loading of the DRM module, and so far It didn't freeze. So in my case I'm pretty sure xserver from git + drm is the cause
And of course, I can't get any info about the freeze, nor in Xorg.0.log or syslog
By setting "vblank_mode=0" I don't get the lockup when activating kde4 desktop effects, but the screen goes completely black! KDE is still alive and all, but I just can't see anything
But using 3d applications seems fine so far (only tried ut2004 for a 15 ins match)..
