Subject: [dpdk-dev] [PATCH v2 00/17] ACL: New AVX2 classify method and several other enhancements.
Date: Mon, 12 Jan 2015 19:16:04 +0000 [thread overview]
Message-ID: <1421090181-17150-1-git-send-email-konstantin.ananyev@intel.com> (raw)
v2 changes:
- When build with the compilers that don't support AVX2 instructions,
make rte_acl_classify_avx2() do nothing and return an error.
- Remove unneeded 'ifdef __AVX2__' in acl_run_avx2.*.
- Reorder order of patches in the set, to keep RTE_LIBRTE_ACL_STANDALONE=y
always buildable.
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):
fix fix compilation issues with RTE_LIBRTE_ACL_STANDALONE=y
app/test: few small fixes fot test_acl.c
librte_acl: make data_indexes long enough to survive idle transitions.
librte_acl: remove build phase heuristsic with negative perfomance
effect.
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.
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.
