[Xen-devel] Radeon DRM dom0 issues

[Michael D Labriola <mlabriol@xxxxxxxx>]

Anyone here running a dom0 w/ Radeon DRM?  I'm having consistent crashes 
with multiple older R600 series (HD 6470 and HD 6570) and unusably slow 
graphics with a newer HD7000 (can see each line refresh indiviually on 
radeonfb tty).  All 3 systems seem to work fine bare metal.

The R600 crashes happen seemingly randomly when using OpenGL Compositor in 
Enlightenment 0.17.  My dom0 need not even have any domUs running. 
Sometimes it happens within a few minutes, sometimes it will run OK for an 
afternoon or so.  Eventually TTM issues an "unable to get page 0" error 
message, the radeon driver follows that up with a 
"radeon_gem_object_create failed to allocate gem" error message.  Then the 
radeon driver starts spamming that gem failure message until I'm forced to 
reboot.

Behavior is identical with kernel versions 3.8, 3.10, and 3.13-rc8.

I'm using Xen 4.2.1 32bit.

xen command line is:  vga=mode=0x314
kernel command line is:  root=/dev/md0 quiet pci=realloc 
console=ttyS0,115200n8 console=tty0

Fingers crossed that there's some magic boot parameter I'm missing.  It's 
been a while since I dabbled with this stuff.  ;-)

Thanks!
