Subject: [PATCH v2 0/3] crypto: allow users to specify acomp hardware from a desired NUMA node
Date: Tue, 23 Jun 2020 16:16:07 +1200 [thread overview]
Message-ID: <20200623041610.7620-1-song.bao.hua@hisilicon.com> (raw)
For a typical Linux server, probably there are several hardware modules.
For example, numa node0 has a compressor, numa node2 has a same module.
Some drivers are automatically using the module near the CPU calling
acomp_alloc.
But it isn't necessarily correct. Just like memory allocation API like
kmalloc and kmalloc_node. Similar optimization may be done for crypto.
-v2:
* fix kern-doc and some codingstyle issues according to Jonathan's comment
* patch 3/3 is rebased againest "[PATCH] mm/zswap: careful error path
implementation in comp_prepare"[1]
