rc5 with starting X (~line 1811) and trying to render something
rc5 with these patches now:
http://lists.freedesktop.org/archives/dri-devel/2013-December/050902.html
I'm not sure what I can do more without getting into trying to debug kernel
code of which I know nothing...
Not really a change with rc5, but I think when starting X the lockups go away
(not really sure). When trying to render something with DRI_PRIME=1 however, it
locks up a bit harder and can't recover apparently because when trying to start
another opengl program, it'll just segfault.
rmmod radeon still creates problems that lock up the cpus and prevent proper
rebooting etc.
With runpm=0 it's not really good either at the moment. For example the
Distance alpha causes a lockup too and after that lockup glxgears says
$ DRI_PRIME=1 glxgears -info
radeon: Failed to allocate virtual address for buffer:
radeon: size : 4352 bytes
radeon: alignment : 4096 bytes
radeon: domains : 4

I'm cramming way too much in here, but I just want to say that the HD 7970M
with the 8970M are the top mobile consumer GPUs AMD currently has and it would
be really cool if the developers could buy that hardware (hey, it's christmas!)
and fix this mess directly. From what I have seen so far it is really close to
working amazingly well. If there's something specific I could test, I'll gladly
try.
Thanks
