from Luke A. Guest
I can confirm that the OS completely hangs when unbinding R9 3=
80 (Tonga Pro)
with X running. Works fine with X off.
Thought I'd add my post from the linked thread, so I can be updated.
------------------
I have amdgpu and vfio-pci both in kernel, used the following to unbind it.
#!/bin/bash
for dev in "$@"; do
vendor=3D$(cat /sys/bus/pci/devices/$dev/vendor)
device=3D$(cat /sys/bus/pci/devices/$dev/device)
if [ -e /sys/bus/pci/devices/$dev/driver ]; then
echo $dev > /sys/bus/pci/devices/$dev/driver/unbind
fi
echo $vendor $device > /sys/bus/pci/drivers/vfio-pci/new_id
done
