Not sure why, but I had to do this way in order for Windows to work. When I tried to put both together, Windows would blue screen all the time. I tried yesterday the configuration below, and it had the same result: <hostdev mode='subsystem' type='pci' managed='yes'> <source> <address domain='0x0000' bus='0x01' slot='0x00' function='0x0'/> </source> <address type='pci' domain='0x0000' bus='0x02' slot='0x07' function='0x0'/> </hostdev> <hostdev mode='subsystem' type='pci' managed='yes'> <source> <address domain='0x0000' bus='0x01' slot='0x00' function='0x1'/> </source> <address type='pci' domain='0x0000' bus='0x02' slot='0x08' function='0x0'/> </hostdev> On Sun, 2017-02-26 at 12:15 +0100, Friedrich Oslage wrote: > Don't know if that's the cause for the amdgpu driver to fail but > in > your libvirt xml you are splitting the multifunction device into > two > separate devices. > > > > For the primary device you have: > > source: <address domain="0x0000" bus="0x01" slot="0x00" > function="0x0"/> > > virtual: <address type="pci" domain="0x0000" bus="0x03" > slot="0x00" function="0x0" multifunction="on"/> > > > > And for the audio subdevice you have: > > source: <address domain="0x0000" bus="0x01" slot="0x00" > function="0x1"/> > > virtual: <address type="pci" domain="0x0000" bus="0x02" > slot="0x09" function="0x0"/> > > > > Which should reside on the same bus/slot as the primary device: > > source: <address domain="0x0000" bus="0x01" slot="0x00" > function="0x1"/> > > virtual: <address type="pci" domain="0x0000" bus="0x03" > slot="0x01" function="0x1"/> > > > > Regards, > > Friedrich > > > > > > From: > guidu...@gmail.com > > Subject: > [vfio-users] R9 290 Passthrough not working on Linux > > Date: > Saturday, Feb 25, 2017 20:59 CET > > To: > vfio-users@redhat.com > > > > > > > > Hi, > > > > For quite some time I have been able to do a pass-through of R9 290 > > to > > Windows VMs using KVM.
