Struct GpuBuddy 

pub struct GpuBuddy(/* private fields */);

GPU buddy allocator instance.

This structure wraps the C gpu_buddy allocator using reference counting. The allocator is automatically cleaned up when all references are dropped.

Refer to the module-level documentation for usage examples.

Implementations

impl GpuBuddy

pub fn new(params: GpuBuddyParams) -> Result<Self>

Create a new buddy allocator.

The allocator manages a contiguous address space of the given size, with the specified minimum allocation unit (chunk_size must be at least 4KB).

pub fn base_offset(&self) -> u64

Get the base offset for allocations.

pub fn chunk_size(&self) -> Alignment

Get the chunk size (minimum allocation unit).

pub fn size(&self) -> u64

Get the total managed size.

pub fn avail(&self) -> u64

Get the available (free) memory in bytes.

pub fn alloc_blocks( &self, mode: GpuBuddyAllocMode, size: u64, min_block_size: Alignment, flags: impl Into<GpuBuddyAllocFlags>, ) -> impl PinInit<AllocatedBlocks, Error>

Allocate blocks from the buddy allocator.

Returns a pin-initializer for AllocatedBlocks.
