Hi Sebastian, I have been making significant changes to the iaa_crypto driver as part of the "zswap compression batching" patch-series [1]. In particular, you may want to review patch 6 ("crypto: iaa - New architecture for IAA device WQ comp/decomp usage & core mapping.") of this series [2]. This is a refinement of some re-architecting of the iaa_crypto driver that I have been posting since v1 of [1] in Oct'24.
