Struct MemControllerProxy

pub struct MemControllerProxy { /* private fields */ }

Implementations

impl MemControllerProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.virtualization/MemController.

pub fn take_event_stream(&self) -> MemControllerEventStream

Get a Stream of events from the remote end of the protocol.

Panics

Panics if the event stream was already taken.

pub fn get_mem_size( &self, ) -> QueryResponseFut<(u64, u64, u64, u64, u64), DefaultFuchsiaResourceDialect>

Get the configured region size, usable region size, plugged size and requestd size

block_size is the size and the alignment in bytes of a memory block. Cannot change. region_size is the size of device-managed memory region in bytes. Cannot change. usable_region_size is the size of the usable device-managed memory region. Can grow up to the region_size. Can only shrink due to VIRTIO_MEM_REQ_UNPLUG_ALL requests. plugged_size is the amount of plugged memory in bytes within the usable device-managed memory region. requested_size is the requested amount of plugged memory within the usable device-managed memory region.

pub fn request_size(&self, requested_size: u64) -> Result<(), Error>

Update the requested size to plug or unplug memory

The driver SHOULD react to resize requests from the device (requested_size in the device configuration changed) by (un)plugging memory blocks.

fn on_closed(&self) -> OnSignals<'_, Unowned<'_, Handle>>

Returns a future that completes when the proxy receives the PEER_CLOSED signal.
