Enum Values

dnnl_quantization_mode_undef

used for unspecified quantization kind

dnnl_quantization_mode_static_sazp

static quantization mode: quantization parameter is computed ahead of time with scale applied after zero-point (\(x_{f32} = scale * (x_{quant} - zp)\)) and passed to oneDNN as an input.

dnnl_quantization_mode_dynamic_mx

dynamic quantization mode following OCP MX spec: quantization parameter is computed by oneDNN following the OCP MX spec formula and written as an output.
