dispatch_amd_4wave_conv2d

def dispatch_amd_4wave_conv2d[input_type: DType, filter_type: DType, output_type: DType, filter_is_fcrs: Bool, has_residual: Bool = False, elementwise_lambda_fn: Optional[def[dtype: DType, width: Int, *, alignment: Int = 1](IndexList[2], SIMD[dtype, width]) capturing -> None] = None](input: TileTensor[input_type, address_space=input.address_space, linear_idx_type=input.linear_idx_type, element_size=input.element_size], filter: TileTensor[filter_type, address_space=filter.address_space, linear_idx_type=filter.linear_idx_type, element_size=filter.element_size], output: TileTensor[output_type, address_space=output.address_space, linear_idx_type=output.linear_idx_type, element_size=output.element_size], stride: IndexList[2], dilation: IndexList[2], symmetric_padding: IndexList[2], num_groups: Int, ctx: DeviceContext, source_ptr: Optional[UnsafePointer[Scalar[output_type], MutAnyOrigin]] = None, beta: Float32 = 0) -> Bool

Try to dispatch a Conv2D to amd_4wave_conv on MI355X.

Returns True if the convolution was handled; False if the caller should fall back (typically to MIOpen). See module docstring for the full acceptance criteria.

When has_residual=True and source_ptr is set, computes D = Conv(A, B) + beta * source via the in-kernel fused residual path (amd_4wave_conv[has_residual=True]). The source pointer is expected to point to an NHWC-contiguous buffer with the same shape as output. When has_residual=False (default), the call is identical to the no-residual variant — no extra ABI overhead beyond the launch packet's 16 bytes (DCE'd source_ptr / stride / beta).

Returns:

Bool
