Struct Group 

pub struct Group { /* private fields */ }

Implementations

impl Group

pub fn from_file(file: File) -> Self

Construct a Group from a pre-opened VFIO group file descriptor.

pub fn open(group: u64) -> Result<Self>

pub fn open_noiommu(group: u64) -> Result<Self>

pub fn find_group_for_device(device_sysfs_path: &Path) -> Result<u64>

pub fn open_device(&self, device_id: &str) -> Result<Device>

pub fn set_container(&self, container: &Container) -> Result<()>

pub fn try_set_container(&self, container: &Container) -> Result<bool>

Try to attach this group to the given container.

Returns Ok(true) if the group was successfully attached, Ok(false) if the kernel rejected the pairing (EINVAL — the IOMMU domains are incompatible), or Err on unexpected failures.

pub fn status(&self) -> Result<GroupStatus>

pub fn set_keep_alive(&self, device_id: &str) -> Result<()>

Skip VFIO device reset when kernel is reloaded during servicing. This feature is non-upstream version of our kernel and will be eventually replaced with iommufd.
