Struct ChipKnobs 

pub struct ChipKnobs {
    pub name: &'static str,
    pub max_dst_tiles: usize,
    pub grid_x: usize,
    pub grid_y: usize,
    pub l1_kib: usize,
}

Per-chip capability knobs — the hardware limits that make the fastest tiling chip-specific. A bigger DST register file lets a core hold a larger reuse sub-block; a bigger worker grid lets the work spread across more cores; more L1 lets wider inner blocks stay resident. The autotuner searches within these, so the SAME matmul compiles to a DIFFERENT (faster) kernel on a different part.

Fields

name: &'static str

Human-readable part name (for the emitted kernel header + provenance).

max_dst_tiles: usize

DST register-file capacity in 32×32 output tiles per acquire (the reuse sub-block ceiling).

grid_x: usize

Worker-grid width (max cores across the N dimension).

grid_y: usize

Worker-grid height (max cores across the M dimension).

l1_kib: usize

Per-core L1 SRAM (KiB) — budgets the resident A/B blocks (bounds in0_block_w).

Implementations

impl ChipKnobs

pub fn wormhole() -> Self

Wormhole b0: 8-tile DST, 8×8 worker grid, ~1.46 MB L1.

pub fn blackhole() -> Self

Blackhole: 16-tile DST (double the reuse), a larger 13×10 worker grid, ~1.46 MB L1.

pub fn tile_limits(&self, knobs: &ComputeKnobs) -> TileLimits

This part’s limits in the units the lattice search filters by, under the requested compute knobs (fp32 dest-accumulate halves the addressable DST tiles).

pub fn cores(&self) -> usize

Cores available.

Trait Implementations

impl Clone for ChipKnobs

fn clone(&self) -> ChipKnobs

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ChipKnobs

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ChipKnobs

fn eq(&self, other: &ChipKnobs) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
