Struct MulticastObject 

pub struct MulticastObject { /* private fields */ }

A multicast object. Drop releases it via cudaMemRelease.

Implementations

impl MulticastObject

pub fn new(prop: &MulticastProp) -> Result<Self>

Create a multicast object with the given props.

pub fn as_raw(&self) -> cudaMemGenericAllocationHandle_t

pub fn add_device(&self, device: &Device) -> Result<()>

Add a participating device to this object.

pub unsafe fn bind_mem( &self, mc_offset: usize, mem_handle: cudaMemGenericAllocationHandle_t, mem_offset: usize, size: usize, flags: u64, ) -> Result<()>

Bind a physical-memory handle (from crate::vmm::MemHandle) at mc_offset within this object, size bytes.

Safety

mem_handle must be a live VMM allocation on a device that was already added via Self::add_device.

pub unsafe fn bind_addr( &self, mc_offset: usize, mem_ptr: *mut c_void, size: usize, flags: u64, ) -> Result<()>

Bind a device address (instead of a handle).

Safety

mem_ptr must be a mapped VMM address on a registered device.

pub fn unbind( &self, device: &Device, mc_offset: usize, size: usize, ) -> Result<()>

Unbind the region [mc_offset, mc_offset + size) from device.

Trait Implementations

impl Debug for MulticastObject

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for MulticastObject

fn drop(&mut self)

Executes the destructor for this type.
