VFIO_CHECK_EXTENSION - _IOW(VFIO_TYPE, VFIO_BASE + 1, __u32)
Check whether an extension is supported. Return: 0 if not supported, 1 (or some other positive integer) if supported. Availability: Always

VFIO_DEVICE_RESET - _IO(VFIO_TYPE, VFIO_BASE + 11)
Reset a device.
Definition at line 289 of file vfio.h.
VFIO_GET_API_VERSION - _IO(VFIO_TYPE, VFIO_BASE + 0)
Report the version of the VFIO API. This allows us to bump the entire API version should we later need to add or change features in incompatible ways. Return: VFIO_API_VERSION Availability: Always

VFIO_GROUP_GET_DEVICE_FD - _IOW(VFIO_TYPE, VFIO_BASE + 6, char)
Return a new file descriptor for the device object described by the provided string. The string should match a device listed in the devices subdirectory of the IOMMU group sysfs entry. The group containing the device must already be added to this context. Return: new file descriptor on success, -errno on failure. Availability: When attached to container
Definition at line 133 of file vfio.h.
VFIO_GROUP_SET_CONTAINER - _IOW(VFIO_TYPE, VFIO_BASE + 4, __s32)
Set the container for the VFIO group to the open VFIO file descriptor provided. Groups may only belong to a single container. Containers may, at their discretion, support multiple groups. Only when a container is set are all of the interfaces of the VFIO file descriptor and the VFIO group file descriptor available to the user. Return: 0 on success, -errno on failure. Availability: Always
Definition at line 106 of file vfio.h.
VFIO_GROUP_UNSET_CONTAINER - _IO(VFIO_TYPE, VFIO_BASE + 5)
Remove the group from the attached container. This is the opposite of the SET_CONTAINER call and returns the group to an initial state. All device file descriptors must be released prior to calling this interface. When removing the last group from a container, the IOMMU will be disabled and all state lost, effectively also returning the VFIO file descriptor to an initial state. Return: 0 on success, -errno on failure. Availability: When attached to container

VFIO_SET_IOMMU - _IOW(VFIO_TYPE, VFIO_BASE + 2, __s32)
Set the iommu to the given type. The type must be supported by an iommu driver as verified by calling CHECK_EXTENSION using the same type. A group must be set to this file descriptor before this ioctl is available. The IOMMU interfaces enabled by this call are specific to the value set. Return: 0 on success, -errno on failure Availability: When VFIO group attached
