Struct PinnedArena 

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

One page-locked host arena with its device alias.

Implementations§

Source§

impl PinnedArena

Source

pub fn alloc(gpu: &dyn GpuBackend, bytes: usize) -> Result<Self>

alloc_host_pinned zero-fills, so a large arena costs one memset at load. The device alias is what the kernels are handed.

Source

pub fn host(&self) -> *mut u8

Source

pub fn dev(&self) -> DevicePtr

Source

pub fn bytes(&self) -> usize

Source

pub fn free(self, gpu: &dyn GpuBackend) -> Result<()>
