Hi Alex,
I am trying to pass through a PCI device to the guest to compare the MSI
interrupt latency with normal device pass through and pass through using VFIO
framework. I used the following script
for dev in $(ls /sys/bus/pci/devices/0000:06:00.0/iommu_group/devices); do
vendor=$(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
done
and added "-device vfio-pci,host,host=0000:06:00.0" to my qemu command line.
I am getting Error - qemu-system-x86_64: -device
vfio-pci,host,host=0000:06:00.0: Property 'vfio-pci.host' doesn't take value
'on'-- when i use the qemu for your git repo and and also the latest v1.3.0-rc1
qemu. I am using Kernel 3.6.7-rt18. Am i missing step ?
