The thread-to-arbiter mapping describes which arbiter can assign jobs to an acceleration engine thread. The existing mappings are functionally correct, but hardcoded and not optimized. Replace the static mappings with an algorithm that generates optimal mappings, based on the loaded configuration. The logic has been made common so that it can be shared between all QAT GEN4 devices.
