VFIO_DEVICE_IOEVENTFD - _IOW(VFIO_TYPE, VFIO_BASE + 16, struct vfio_device_ioeventfd)

Perform a write to the device at the specified device fd offset, with the specified data and width when the provided eventfd is triggered. vfio bus drivers may not support this for all regions, for all widths, or at all. vfio-pci currently only enables support for BAR regions, excluding the MSI-X vector table.

Return: 0 on success, -errno on failure.

Fields

argsz: __u32

flags: __u32

offset: __u64

data: __u64

fd: __s32
