binding/unbinding devices to vfio-pci
...vfio-pci.
That can be changed by:
# echo 0 > /sys/bus/pci/drivers_autoprobe
But then we have to worry about races from any devices that might have
been hotplugged in the interim.
To unbind:
1) echo ssss:bb:dd.f > /sys/bus/pci/drivers/vfio-pci/unbind
2) echo ssss:bb:dd.f > /sys/bus/pci/drivers_probe
So we don't have to manually remember or hunt down the host driver for
the device. Thanks,
Alex

binding/unbinding devices to vfio-pci
Alex,
I'm trying to think through how binding/unbinding of devices will
work with VFIO for platform devices and have a couple of questions
about how vfio-pci works.
When you bind a device to vfio-pci, e.g.:
# echo 1102 0002 > /sys/bus/pci/drivers/vfio-pci/new_id
...I understand that the echo into 'new_id' tells the
vfio pci driver that it now handles the specified PCI ID.
But
