unsafe fn do_map(&self, map: MappingInfo) -> Result<AddMapResult>

Trait Implementations

impl AsRawDescriptors for VfioWrapper

fn as_raw_descriptors(&self) -> Vec<RawDescriptor>

Returns the underlying raw descriptors.

impl MemoryMapper for VfioWrapper

fn add_map(&mut self, map: MappingInfo) -> Result<AddMapResult>

Creates a new mapping. If the mapping overlaps with an existing mapping, return Ok(false).

unsafe fn vfio_dma_map(
    &mut self,
    iova: u64,
    hva: u64,
    size: u64,
    prot: Protection
) -> Result<AddMapResult>

Exports the specified IO region.

fn remove_map(&mut self, iova_start: u64, size: u64) -> Result<RemoveMapResult>

Removes all mappings within the specified range.

fn get_mask(&self) -> Result<u64>

fn supports_detach(&self) -> bool

Whether or not endpoints can be safely detached from this mapper.

fn id(&self) -> u32

Gets an identifier for the MemoryMapper instance. Must be unique among instances of the same trait implementation.

fn reset_domain(&mut self) -> Option<EventAsync>

Resets the mapper’s domain back into its initial state. Only necessary if |supports_detach| returns true.

fn start_export_session(&mut self, _ex: &Executor) -> Result<Event>

Starts an export session with the mapper.

fn export(&mut self, _iova: u64, _size: u64) -> Result<Vec<MemRegion>>

Multiple MemRegions should be returned when the gpa is discontiguous or perms are different.

fn release(&mut self, _iova: u64, _size: u64) -> Result<()>

Releases a previously exported region.
