i google related threads and carried out preparation:
1. set module parameter "vfio_iommu_type1.allow_unsafe_interrupts"=1
2. raise ulimit: ulimit -l unlimited
3. compile kernel without swap memory support, ATI KMS, alsa for ATI if any
4. compile xorg without ati, vesa driver
But the guest boots with BSOD and qemu shows the following messages, can anyone
helps?
for dev in $(ls /sys/bus/pci/devices/0000:01:00.0/iommu_group/devices); do
vendor=$(cat /sys/bus/pci/devices/$dev/vendor)
device=$(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
