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.
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
