Subject: [dpdk-dev] [PATCH v4 00/14] acl: introduce AVX512 classify methods
Date: Tue,  6 Oct 2020 16:03:02 +0100
Message-ID: <20201006150316.5776-1-konstantin.ananyev@intel.com> (raw)
In-Reply-To: <20201005184526.7465-1-konstantin.ananyev@intel.com>

These patch series introduce support of AVX512 specific classify
implementation for ACL library.
It adds two new algorithms:
 - RTE_ACL_CLASSIFY_AVX512X16 - can process up to 16 flows in parallel.
   It uses 256-bit width instructions/registers only
   (to avoid frequency level change).
   On my SKX box test-acl shows ~15-30% improvement
   (depending on rule-set and input burst size)
   when switching from AVX2 to AVX512X16 classify algorithms.
 - RTE_ACL_CLASSIFY_AVX512X32 - can process up to 32 flows in parallel.
   It uses 512-bit width instructions/registers and provides higher
   performance then AVX512X16, but can cause frequency level change.
   On my SKX box test-acl shows ~50-70% improvement
   (depending on rule-set and input burst size)
   when switching from AVX2 to AVX512X32 classify algorithms.
   ICX and CLX testing showed similar level of speedup.

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.

Depends-on: patch-79310 ("eal/x86: introduce AVX 512-bit type")

v3 -> v4
  Fix problems with meson 0.47
  Updates to conform latest changes in the mainline
  (removal of RTE_MACHINE_CPUFLAG_*)
  Fix checkpatch warnings

v2 -> v3:
  Fix checkpatch warnings
  Split AVX512 algorithm into two and deduplicate common code
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
