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
