… lowp gemm This goes in hand with oneapi-src/oneDNN#2194 which sets the weights as constant for Arm Compute Library (ACL) lowp gemm objects. This is a temp fix which is needed because the lowp gemm ACL object in oneDNN is now holding more state. Hence, we need to make sure that the cahce maps a layer with a specific set of weights to the oneDNN primitive storing those weights. We're currently working on the proper fix for this which involves making lowp_gemm stateless and fixed-format in ACL and oneDNN.
