Re: [Xen-devel] Windows 8 VGA Passthrough

[John Wargo <wargo.john25@xxxxxxxxx>]

I've made quite a bit of changes since my last email, and so far here's 
what I've got:
AMD FX6300
ASUS M5A99X evo r2.0
ASUS Radeon 6670 (Dom0)
XFX Radeon 7850 (Win8)

Right now I've got AMD Catalyst (latest stable) installed in windows 8, 
and device manager shows my Radeon 7850 reporting no issues.
I'm currently passing it through as secondary (gfx_passthrough=0), 
however I cannot plug my monitor into it.
After taking debugging steps, I've come up with the attached debugging info:
info - xl info
dmesg - xl dmesg
grub - a copy of '/etc/default/grub'
win8.cfg - the configuration I'm using to launch windows 8

Fedora bug reporting tool caught a kernel bug at 
'drivers/gpu/drm/ttm/ttm_bo.c:210', I have compiled xen from source, and 
I'm using it as a kernel (or really part of it).
Is there some sort of AMD Radeon patch I need to use (I saw one on the 
wiki, but it appeared to be several years old), or is it a needed 
configuration?
Thanks for your time,
-John
