### NVMe Driver



The logic which support hotplug of vfio-attached devices has been implemented in SPDK, but to

totally enable this feature, there is still some work need to be done for kernel vfio-pci driver.

vfio-pci driver should trigger one "remove" uevent at the very beginning of the remove interface

of pci driver, this will make sure the SPDK could detect the event and release the vfio-attached

device Fd and related resource when the device removed.

SPDK now supports hotplug for vfio-attached devices. But there is one thing keep in mind:

Only physical removal events are supported; removing devices via the sysfs `remove` file will not work.
