[dpdk-dev] [PATCH 00/17] ACL: New AVX2 classify method and several other enhancements.

[Konstantin Ananyev <konstantin.ananyev@intel.com>]

This patch series contain several fixes and enhancements for ACL library.
See complete list below.
Two main changes that are externally visible:
- Introduce new classify method:  RTE_ACL_CLASSIFY_AVX2.
It uses AVX2 instructions and 256 bit wide data types
to perform internal trie traversal.
That helps to increase classify() throughput.
This method is selected as default one on CPUs that supports AVX2.
- Introduce new field in the build config structure: max_size.
It specifies maximum size that internal RT structure for given context
can reach.
The purpose of that is to allow user to decide about space/performance trade-off
(faster classify() vs less space for RT internal structures)
for each given set of rules. 

Konstantin Ananyev (17):
  app/test: few small fixes fot test_acl.c
  librte_acl: fix a bug with incorrect size calculation for
    data_indexes. make data_indexes long enough to survive idle
    transitions and remove unneeded code in acl_match_check().
  librte_acl: fixes/changes in ACL build phase. remove rule-wildness
    based heuristsics that causes negative perfomance effect (more
    tries,bigger RT tables). changed memcpy to memove for overlapping
    locations.
  librte_acl: fix a bug at build phase that can cause matches beeing
    overwirtten.
  librte_acl: introduce DFA nodes compression (group64) for identical
    entries.
  librte_acl: build/gen phase - simplify the way match nodes are
    allocated.
  librte_acl: make scalar RT code to be more similar to vector one.
  librte_acl: a bit of RT code deduplication. Move common check for
    input parameters up into rte_acl_classify_alg().
  EAL: introduce rte_ymm and relatives in rte_common_vect.h.
  librte_acl: add AVX2 as new rte_acl_classify() method
  test-acl: add ability to manually select RT method.
  librte_acl: Remove search_sse_2 and relatives.
  libter_acl: move lo/hi dwords shuffle out from calc_addr
  libte_acl: make calc_addr a define to deduplicate the code.
  libte_acl: introduce max_size into rte_acl_config.
  libte_acl: remove unused macros.
  libte_acl: fix compilation issues with RTE_LIBRTE_ACL_STANDALONE=y.
