The main use case of this function is to calculate the hash value for a single data, so there is no bulk implementation. For performance reasons, the implementation was placed in a public header. It is the responsibility of the user to ensure the platform supports GFNI (by doing runtime checks of rte_thash_gfni_supported variable) before calling these functions. v4: - included rte_log.h inside the rte_thash_gfni.h v3: - implementation moved to x86 specific header - added rte_thash_gfni_supported() instead of the variable - removed RTE_INIT section, due to adding rte_thash_gfni_supported() - reworked rte_thash_complete_matrix() to make it easier tor read v2: - fixed typos - made big_rss_key static const and indented - addressed Konstantin's comments Vladimir Medvedkin (5): hash: add new toeplitz hash implementation hash: enable gfni thash implementation doc/hash: update documentation for the thash library test/thash: add tests for a new Toeplitz hash function test/thash: add performance tests for the Toeplitz hash app/test/meson.build | 2 + app/test/test_thash.c | 237 ++++++++++++++++++++++++++++ app/test/test_thash_perf.c | 120 ++++++++++++++ doc/api/doxy-api-index.md | 1 + doc/guides/prog_guide/toeplitz_hash_lib.rst | 37 ++++- doc/guides/rel_notes/release_21_11.rst | 4 + lib/hash/meson.build | 1 + lib/hash/rte_thash.c | 71 ++++++++- lib/hash/rte_thash.h | 54 +++++++ lib/hash/rte_thash_gfni.h | 87 ++++++++++ lib/hash/rte_thash_x86_gfni.h | 221 ++++++++++++++++++++++++++ lib/hash/version.map | 3 + 12 files changed, 830 insertions(+), 8 deletions(-) create mode 100644 app/test/test_thash_perf.c create mode 100644 lib/hash/rte_thash_gfni.h create mode 100644 lib/hash/rte_thash_x86_gfni.h -- 2.7.4
