Subject: [dpdk-dev] [PATCH v2 00/12] acl: introduce AVX512 classify method
Date: Tue, 15 Sep 2020 17:50:13 +0100	[thread overview]
Message-ID: <20200915165025.543-1-konstantin.ananyev@intel.com> (raw)
In-Reply-To: <20200807162829.11690-1-konstantin.ananyev@intel.com>

These patch series introduce support of AVX512 specific classify
implementation for ACL library.
Inside it contains two code-paths –
one uses mostly 256 bit instruction/registers and can
process up to 16 flows in parallel.
second uses 512 bit instruction/registers over majority of
places and can process up to 32 flows in parallel.
This runtime code-path selection is done internally based
on input burst size and is totally opaque to the user.
On my SKX box test-acl shows ~20-65% improvement
(depending on rule-set and input burst size)
when switching from AVX2 to AVX512 classify algorithms.
ICX and CLX testing showed similar level of speedup: up to ~50-60%.
Current AVX512 classify implementation is only supported on x86_64.
Note that this series introduce a formal ABI incompatibility
with previous versions of ACL library.

v1 -> v2:
  Deduplicated 8/16 code paths as much as possible
  Updated default algorithm selection
    Removed library constructor to make it easier integrate with
    https://patches.dpdk.org/project/dpdk/list/?series=11831
  Updated docs

These patch series depends on:
https://patches.dpdk.org/patch/73922/mbox/
to be applied first.

Konstantin Ananyev (12):
  acl: fix x86 build when compiler doesn't support AVX2
  doc: fix mixing classify methods in ACL guide
  acl: remove of unused enum value
  acl: remove library constructor
  app/acl: few small improvements
  test/acl: expand classify test coverage
  acl: add infrastructure to support AVX512 classify
  acl: introduce AVX512 classify implementation
  acl: enhance AVX512 classify implementation
  acl: for AVX512 classify use 4B load whenever possible
  test/acl: add AVX512 classify support
  app/acl: add AVX512 classify support
