Detailed Description

struct vfio_device_ops - VFIO bus driver device callbacks

: Called when userspace creates new file descriptor for device : Called when userspace releases file descriptor for device : Perform read(2) on device file descriptor : Perform write(2) on device file descriptor : Perform ioctl(2) on device file descriptor, supporting VFIO_DEVICE_* operations documented below : Perform mmap(2) on a region of the device file descriptor
