<br>
first time posting on a mailinglist, so I hope this works out.<br>
<br>
<br>
A couple of days ago I had a simmilar issue with an amd gpu and windows<br>
8.1. Maybe my notes could be helpful.<br>
<br>
<br>
Background:<br>
Hardware used:<br>
Xeon E3-1246v3<br>
MSI H97 Guard Pro<br>
Asus R9 280 DC2T<br>
24 GB Ram (2x8 GB, 2x4 GB)<br>
<br>
Arch Linux with kenel 4.1.6-1<br>
<br>
I have a working Windows 8.1 virtual machine with gpu passthrough with<br>
an asus r9 280 dc2t.<br>
This one was created with a <4.0 kernel (3.18 I think), pci-stub,<br>
libvirt in qemu:\\\system over a year ago and has been running mostly<br>
without problems. I could update the gpu driver and the ccc without<br>
problems.<br>
After I recently read at aw's blog that libvirt now supports passthrough<br>
in user-session, i used vfio instead of pci-stub and could use the<br>
virtual machine in user mode.<br>
<br>
<br>
Actual issue:<br>
For testing purposes I then wanted to create another virtual machine,<br>
which then had the issue, that after installation of the gpu driver, the<br>
vm would not boot unless the gpu was removed from it.<br>
I used the same iso for installation, that I used for the working<br>
virtual machine. After some attempts I even copied the installer of the<br>
driver from one vm to the other, but it did not work.<br>
<br>
<br>
Some of the steps I tried were:<br>
- Installation of Catalyst 15.7.1 gave a bluescreen with<br>
"system_thread_exception_not_handled (atikmdag.sys)".<br>
- Attempted installation of the driver over the device manager resulted<br>
in an immediate restart without installing the driver.<br>
- Installation of the driver over the device manager in safe mode<br>
worked, but a restart without safe mode resultet in permanent restarts<br>
until the vm was forced shutdown.<br>
- Copying the installed files (not the installer) from the windows/...<br>
directories from the working one to the other one let me choose the<br>
driver in the device manager, but also resulted in permanent restarts<br>
until the gpu was removed from the vm.<br>
- Starting the virtual machine over the command line without<br>
virt-manager, installing the driver over device manager and rebooting<br>
worked once and then resulted in restarts.<br>
<br>
I tried for some days a couple of combinations of the above and some<br>
suggestions I found through google, but nothing helped.<br>
<br>
<br>
What finally did help was this:<br>
<br>
Start a fresh installation of windows 8.1 in qemu without libvirt. It<br>
contained only the minimum needed to start (cpu, ram ...; ovmf image;<br>
installation iso; virtual disk; qxl vga; gpu for passthrough with audio).<br>
During installation I disabled the windows setting for loading new<br>
drivers. After the installation I didn't restart, update or change any<br>
setting. The gpu had only the microsoft basic driver with a code 10 and<br>
did not show anything.<br>
I downloaded the 15.7.1 driver from amd, extracted it and stopped the<br>
installation.<br>
I opened the settings for resolution and disabled the output on the qxl<br>
gpu, which left me with no output.<br>
After that I killed and restarted the virtual machine, so the output was<br>
only on the r9 280 and installed the driver manually over the device<br>
manager. This worked fine and I had no bluescreen or restarts.<br>
After the installation I was able to reboot the virtual machine without<br>
problems and install the ccc including the hdmi driver. I could also<br>
enable the qxl gpu, install new drivers for it and install virtio drivers.<br>
<br>
<br>
My qemu start script now looks like this:<br>
<br>
qemu-system-x86_64 -enable-kvm -m 4096 -cpu host,kvm=off -smp<br>
4,sockets=1,cores=4,threads=1 \<br>

\<br>
-drive<br>
file=/media/Daten/VirtuelleMaschinen/WinTest_ovmf.qcow2,if=virtio,format=qcow2<br>
\<br>
-vga qxl \<br>
-device vfio-pci,host=01:00.0 -device vfio-pci,host=01:00.1<br>
