            Bug ID: 94530
           Summary: AMD R9 Nano reset problem
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: creakbeat@gmail.com

I am trying to passthrough R9 Nano to a VM, and facing some problems. After
Windows 7 has been installed, the latest AMD Crimson edition driver is
installed. At first time, the driver works properly. There appears to have the
problem when I power off the vm and restart it. The driver was not working
until I reboot the host.

Here is my system.

Manufacturer: Supermicro
Product Name: X10DAi
CPU: Intel(R) Xeon(R) CPU E5-2620 v3 @ 2.40GHz
memory: 8GB 
linux kernel: 3.19.0

$ cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-3.19.0 root=UUID=fc28306a-e168-406a-805d-cadf70de53ec
ro quiet splash intel-iommu=on vfio_iommu_type1.allow_unsafe_interrupts=1
vt.handoff=7

I tried to use qemu version 2.3.1, 2.4.1, and 2.5.1. 
I also added the device id number into the function vfio_setup_resetfn(), but
the problem remains.

I start my virtual machine with the following code.

qemu-system-x86_64 -enable-kvm \
-M pc -m 4096 -cpu host \
-smp 4,sockets=1,cores=4,threads=1 \
-rtc base=localtime \
-vnc :0 \
-vga none \
-device lsi,id=scsi0,bus=pci.0 \
-device vfio-pci,host=03:00.0,x-vga=on \
-device vfio-pci,host=03:00.1 \
-hda $1 \
-monitor stdio

Hi,

I'am experiencing the same problem with my 'R9 Fury' (also Fiji), but I'm
unable to install AMD Crimson drivers for a few weeks now. Last working version
was 16.3.1 (I think). 
Now, when the installer is trying to update/install the display driver, my
screen goes blank, and the HOST (as well as the VM) hangs. Only a power off can
help.

Until 16.3.1 the screen went blank also (and the GPU fans started to spin at
max speed), but the VM/HOST did NOT hang.

If more info is required, I am glad to provide them :)

See you,
Michael

I've got a VM which uses an R9 Nano via passthrough. Like Michael said, my
system hangs both the VM and the host machine when installing AMD drier
updates. Likewise my VM freezes and the fan revs up to maximum upon a normal
resart of the VM, or I change anything in the QEMU startup command (e.g. adding
another hard drive to the VM). And the only way to stop either of those issues
is to power off the host machine.

The only way I have been able to change the driver for my card is during a
fresh install of Windows when no drivers are previously installed (aside from
the basic prepackaged ones are within Windows). Then I can get the lastest
drivers I already downloaded from another hard drive and install them on my
system, and it will work for the most part. However this doesn't address the
core issue.

Whilst I'm unsure if this website is the appropriate place to file this bug
report, the previous two posts are the only place I've seen this exact issue
mentioned.

Please try the latest 4.9 kernel or my 4.10-wip branch:

It seems, it's not a vfio issue. There are (possibly) some firmware/hw
problems, as it happens also on bare metal Windows (at least on my machine):
