Original PR (merged into master): #52261
Add support for caching oneDNN matmul primitives in the
mkl_aarch64
build. (Doesn't affect vanilla TF.) The changes in TF are small. Most of the changes are in the patch file for the oneDNN aarch64 repository.This is more of a performance improvement (feature) PR rather than a performance regression fix. Creating a cherry-pick just in case it can be accepted.
@cfRod Could you please help post some performance numbers here (e.g., how much improvements you saw for some models)? Thank you very much!
