X-BeenThere: dev@dpdk.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: patches and discussions about DPDK List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sun, 14 Dec 2014 18:11:34 -0000 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. app/test-acl/main.c | 126 +++-- app/test/test_acl.c | 8 +- examples/l3fwd-acl/main.c | 3 +- examples/l3fwd/main.c | 2 +- lib/librte_acl/Makefile | 9 + lib/librte_acl/acl.h | 58 ++- lib/librte_acl/acl_bld.c | 392 +++++++--------- lib/librte_acl/acl_gen.c | 268 +++++++---- lib/librte_acl/acl_run.h | 7 +- lib/librte_acl/acl_run_avx2.c | 58 +++ lib/librte_acl/acl_run_avx2.h | 288 ++++++++++++ lib/librte_acl/acl_run_scalar.c | 65 ++- lib/librte_acl/acl_run_sse.c | 585 +----------------------- lib/librte_acl/acl_run_sse.h | 357 +++++++++++++++ lib/librte_acl/acl_vect.h | 132 +++--- lib/librte_acl/rte_acl.c | 25 +- lib/librte_acl/rte_acl.h | 4 + lib/librte_acl/rte_acl_osdep_alone.h | 47 +- lib/librte_eal/common/include/rte_common_vect.h | 39 +- lib/librte_lpm/rte_lpm.h | 2 +- 20 files changed, 1420 insertions(+), 1055 deletions(-) create mode 100644 lib/librte_acl/acl_run_avx2.c create mode 100644 lib/librte_acl/acl_run_avx2.h create mode 100644 lib/librte_acl/acl_run_sse.h -- 1.8.5.3
