Struct PinnedBuffer

pub struct PinnedBuffer {
    pub ptr: *mut c_void,
    pub bytes: usize,
}

Fields§

§ptr: *mut c_void§bytes: usize

Implementations§

impl PinnedBuffer

pub fn new(bytes: usize) -> Result<Self>

pub fn device_ptr(&self) -> Result<u64>

Device pointer the GPU uses to address this pinned host allocation.

On GB10’s unified LPDDR (unified addressing) this equals the host pointer numerically — the property the UMA zero-copy expert arena relies on. cuMemAllocHost memory is portable + page-locked + device-accessible, so no Mapped flag is required.
