Struct __tile1024i

    tile: Simd<u8, 1024>,
}

🔬This is a nightly-only experimental API. (x86_amx_intrinsics #126622)

Available on x86-64 only.

A tile register, used by AMX instructions.

This type is the same as the __tile1024i type defined by Intel, representing a 1024-byte tile register. Usage of this type typically corresponds to the amx-tile and up target features for x86_64.

This struct contains the tile configuration information as well as the tile itself. The tile configuration information consists of the row count and the size of each column in bytes, with row * colsb never exceeding 1024.

The typical usage pattern looks like

let tile = MaybeUninit::uninit();
let tile_ptr = tile.as_mut_ptr();

(*tile_ptr).rows = rows;
(*tile_ptr).colsb = colsb;
__tile_zero(tile_ptr);

let tile = tile.assume_init();

Most intrinsics using __tile1024i (except for the store intrinsics) have a destination parameter of type *mut __tile1024i, and it expects the rows and colsb fields of the destination to be initialized. After the function call, the whole struct can be assumed to be initialized. Moreover, for dot-product intrinsics, it is UB if the shape of two operands are not compatible as a matrix product or if the shape of the destination doesn’t match the expected shape.
