This patch series implements vectorized lookup using AVX512 for ipv4 dir24_8 and ipv6 trie algorithms. Also introduced rte_fib_set_lookup_fn() to change lookup function type. Added option to select lookup function type in testfib application.
v3: - separate out the AVX-512 code into a separate file v2: - rename rte_zmm to __rte_x86_zmm to reflect its internal usage - make runtime decision to use avx512 lookup Vladimir Medvedkin (8): eal: introduce zmm type for AVX 512-bit fib: make lookup function type configurable fib: move lookup definition into the header file fib: introduce AVX512 lookup fib6: make lookup function type configurable fib6: move lookup definition into the header file fib6: introduce AVX512 lookup app/testfib: add support for different lookup functions app/test-fib/main.c | 58 ++++++- lib/librte_eal/x86/include/rte_vect.h | 20 +++ lib/librte_fib/Makefile | 24 +++ lib/librte_fib/dir24_8.c | 281 ++++++---------------------------- lib/librte_fib/dir24_8.h | 226 ++++++++++++++++++++++++++- lib/librte_fib/dir24_8_avx512.c | 165 ++++++++++++++++++++ lib/librte_fib/dir24_8_avx512.h | 24 +++ lib/librte_fib/meson.build | 20 +++ lib/librte_fib/rte_fib.c | 20 ++- lib/librte_fib/rte_fib.h | 23 +++ lib/librte_fib/rte_fib6.c | 19 ++- lib/librte_fib/rte_fib6.h | 21 +++ lib/librte_fib/rte_fib_version.map | 2 + lib/librte_fib/trie.c | 161 ++++--------------- lib/librte_fib/trie.h | 119 +++++++++++++- lib/librte_fib/trie_avx512.c | 269 ++++++++++++++++++++++++++++++++ lib/librte_fib/trie_avx512.h | 20 +++ 17 files changed, 1100 insertions(+), 372 deletions(-) create mode 100644 lib/librte_fib/dir24_8_avx512.c create mode 100644 lib/librte_fib/dir24_8_avx512.h create mode 100644 lib/librte_fib/trie_avx512.c create mode 100644 lib/librte_fib/trie_avx512.h -- 2.7.4
