Implementations

impl VmMemoryClient

pub fn new(tube: Tube) -> Self

fn request(&self, request: &VmMemoryRequest) -> Result<VmMemoryResponse>

fn request_unit(&self, request: &VmMemoryRequest) -> Result<()>

pub fn prepare_shared_memory_region( &self, alloc: Alloc, cache: MemCacheType ) -> Result<()>

Prepare a shared memory region to make later operations more efficient. This may be a no-op depending on underlying platform support.

pub fn register_memory( &self, source: VmMemorySource, dest: VmMemoryDestination, prot: Protection, cache: MemCacheType ) -> Result<VmMemoryRegionId>

pub fn dynamically_free_memory_range( &self, guest_address: GuestAddress, size: u64 ) -> Result<()>

Call hypervisor to free the given memory range.

pub fn dynamically_reclaim_memory_range( &self, guest_address: GuestAddress, size: u64 ) -> Result<()>

Call hypervisor to reclaim a priorly freed memory range.

pub fn unregister_memory(&self, region: VmMemoryRegionId) -> Result<()>

Unregister the given memory slot that was previously registered with RegisterMemory.

pub fn register_io_event_with_alloc( &self, evt: Event, allocation: Alloc, offset: u64, datamatch: Datamatch ) -> Result<()>

Register an ioeventfd by looking up using Alloc info.

pub fn unregister_io_event_with_alloc( &self, evt: Event, allocation: Alloc, offset: u64, datamatch: Datamatch ) -> Result<()>

Unregister an eventfd by looking up using Alloc info.

pub fn register_io_event( &self, event: Event, addr: u64, datamatch: Datamatch ) -> Result<()>

Register an eventfd with raw guest memory address.

pub fn unregister_io_event( &self, event: Event, addr: u64, datamatch: Datamatch ) -> Result<()>

Unregister an eventfd with raw guest memory address.

pub fn balloon_target_reached(&self, size: u64) -> Result<()>
