Also introduced rte_fib_set_lookup_fn() to change lookup function type. Added option to select lookup function type in testfib application. Depends-on: patch-79338 ("eal: add max SIMD bitwidth") v9: - meson reworked - integration with max SIMD bitwidth patchseries - changed the logic of function selection on init v8: - remove Makefile related changes - fix missing doxygen for lookup_type - add release notes v7: - fix RTE_X86_ZMM_MASK macro v6: - style fixes v5: - prefix zmm macro in rte_vect.h with RTE_X86 - remove unnecessary typedef for _x86_zmm_t - reword commit title - fix typos v4: - use __rte_aligned() instead of using compiler attribute directly - rework and add comments to meson.build 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/x86: introduce AVX 512-bit type 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 | 65 ++++++- doc/guides/rel_notes/release_20_11.rst | 3 + lib/librte_eal/x86/include/rte_vect.h | 19 ++ lib/librte_fib/dir24_8.c | 329 ++++++++------------------------- 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 | 51 +++++ lib/librte_fib/rte_fib.c | 21 ++- lib/librte_fib/rte_fib.h | 26 +++ lib/librte_fib/rte_fib6.c | 20 +- lib/librte_fib/rte_fib6.h | 25 +++ lib/librte_fib/rte_fib_version.map | 2 + lib/librte_fib/trie.c | 191 ++++++------------- lib/librte_fib/trie.h | 119 +++++++++++- lib/librte_fib/trie_avx512.c | 269 +++++++++++++++++++++++++++ lib/librte_fib/trie_avx512.h | 20 ++ 17 files changed, 1185 insertions(+), 390 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
