Struct ExpertArena 

pub struct ExpertArena { /* private fields */ }

A ring of pinned per-layer slabs. Slot geometry is one expert record (record_stride, a 4 KiB multiple so O_DIRECT / RDMA landings are aligned).

Implementations

impl ExpertArena

pub fn new( num_slabs: u32, slots_per_slab: u32, record_stride: usize, ) -> Result<Self>

Allocate num_slabs * slots_per_slab * record_stride bytes of pinned LPDDR and confirm the GB10 same-VA property (fail loudly otherwise — the zero-copy patch would be silently wrong on a host without it).

pub fn num_slabs(&self) -> u32

pub fn slots_per_slab(&self) -> u32

pub fn record_stride(&self) -> usize

pub fn slot_host_ptr(&self, slab: u32, slot: u32) -> Result<*mut u8>

Host pointer of a slot — the O_DIRECT / RDMA landing target.

pub fn slot_dev_va(&self, slab: u32, slot: u32) -> Result<u64>

Device VA of a slot — what the expert pointer table is patched to.

pub fn base_ptr(&self) -> *mut c_void

Raw pinned base as a *mut c_void (for future ibv_reg_mr).

pub fn total_bytes(&self) -> usize
