<p dir="ltr">Hey all</p>
<p dir="ltr">First experiment with VFIO. I'm running </p>
<p dir="ltr">Fedora 23 x64 with an Intel i7-6700k, and an R9 290.
Host is booting with UEFI, guest is booting via UEFI.
VT-D/VT-X/IOMMU are all enabled and seeming to function. The
card works fine under Windows 10 (real hardware). Qemu's log and
"dmesg | grep kvm" dont show any obvious errors. </p>
<p dir="ltr">I'm using the builds from the virt-preview repo. </p>
<p dir="ltr">My problem is.. The Win7 (and Win8.1) guests are
perfectly fine and stable until I try to install the amd crimson
drivers. Then Windows BSODs, yelling about an unhandled
exception. If I unpack the install and install things piecemeal,
then I can install the HDMI audio driver, and everything else
okay...except for the display driver. Installing the display
driver causes the BSOD. </p>
<p dir="ltr">This happens on kernels 4.1 and 4.2. I'm using
vfii-stub to stub out the hardware during boot on the host. </p>
<p dir="ltr">I don't know what info would be helpful for
debugging, just ask and I will supply as soon as I can. Has
anyone had any success passing an r9 290?</p>
<p dir="ltr">Cheers<br>
Eric</p>
