LevelZeroMemoryManager

Struct LevelZeroMemoryManager 

Source
pub struct LevelZeroMemoryManager { /* private fields */ }
Expand description

Manages a pool of Level Zero device buffers, returning opaque u64 handles.

Uses explicit host-staging buffers and command lists for host↔device data transfers, matching the Level Zero programming model.

All public methods take &self so the manager can be shared behind Arc.

Implementations§

Source§

impl LevelZeroMemoryManager

Source

pub fn new(device: Arc<LevelZeroDevice>) -> Self

Create a new memory manager backed by device.

Source

pub fn alloc(&self, bytes: usize) -> LevelZeroResult<u64>

Allocate bytes bytes of device memory.

Returns an opaque handle. The caller must eventually call free.

Source

pub fn free(&self, handle: u64) -> LevelZeroResult<()>

Release the device buffer associated with handle.

Unknown handles are silently ignored (idempotent free).

Source

pub fn copy_to_device(&self, handle: u64, src: &[u8]) -> LevelZeroResult<()>

Upload host bytes src into the device buffer identified by handle.

Allocates a temporary host-side staging buffer, copies the data into it, then uses a command list to schedule the device copy and waits for completion.

Source

pub fn copy_from_device( &self, dst: &mut [u8], handle: u64, ) -> LevelZeroResult<()>

Download device buffer handle into dst.

Uses a host-staging buffer and a command list for the device→host copy.
