The related marco definition can be found in linux kernel: arch/arm64/include/uapi/asm/hwcap.h This patch incorporates those changes to the eal library. Signed-off-by: Chengwen Feng Signed-off-by: Wei Hu (Xavier) Reviewed-by: Ruifeng Wang --- v4 -> v5: No change. v3 -> v4: Update commit log. v2 -> v3: 1. Change commit log. 2. Add HWCAP2_FLAGM2 and HWCAP2_FRINT to rte_cpu_feature_table[]. 3. Add the flags for newly added items into enum rte_cpu_flag_t. v1 -> v2: Adds more sve-related definition to rte_cpu_feature_table, sunch as SVE2, etc. --- lib/librte_eal/arm/include/rte_cpuflags_64.h | 13 +++++++++++++ lib/librte_eal/arm/rte_cpuflags.c | 13 +++++++++++++ 2 files changed, 26 insertions(+) diff --git a/lib/librte_eal/arm/include/rte_cpuflags_64.h b/lib/librte_eal/arm/include/rte_cpuflags_64.h index 95cc01474..aa7a56d49 100644 --- a/lib/librte_eal/arm/include/rte_cpuflags_64.h +++ b/lib/librte_eal/arm/include/rte_cpuflags_64.h @@ -22,6 +22,19 @@ enum rte_cpu_flag_t { RTE_CPUFLAG_SHA2, RTE_CPUFLAG_CRC32, RTE_CPUFLAG_ATOMICS, + RTE_CPUFLAG_SVE, + RTE_CPUFLAG_SVE2, + RTE_CPUFLAG_SVEAES, + RTE_CPUFLAG_SVEPMULL, + RTE_CPUFLAG_SVEBITPERM, + RTE_CPUFLAG_SVESHA3, + RTE_CPUFLAG_SVESM4, + RTE_CPUFLAG_FLAGM2, + RTE_CPUFLAG_FRINT, + RTE_CPUFLAG_SVEI8MM, + RTE_CPUFLAG_SVEF32MM, + RTE_CPUFLAG_SVEF64MM, + RTE_CPUFLAG_SVEBF16, RTE_CPUFLAG_AARCH64, /* The last item */ RTE_CPUFLAG_NUMFLAGS,/**< This should always be the last! */ diff --git a/lib/librte_eal/arm/rte_cpuflags.c b/lib/librte_eal/arm/rte_cpuflags.c index caf3dc83a..7b257b787 100644 --- a/lib/librte_eal/arm/rte_cpuflags.c +++ b/lib/librte_eal/arm/rte_cpuflags.c @@ -95,6 +95,19 @@ const struct feature_entry rte_cpu_feature_table[] = { FEAT_DEF(SHA2, REG_HWCAP, 6) FEAT_DEF(CRC32, REG_HWCAP, 7) FEAT_DEF(ATOMICS, REG_HWCAP, 8) + FEAT_DEF(SVE, REG_HWCAP, 22) + FEAT_DEF(SVE2, REG_HWCAP2, 1) + FEAT_DEF(SVEAES, REG_HWCAP2, 2) + FEAT_DEF(SVEPMULL, REG_HWCAP2, 3) + FEAT_DEF(SVEBITPERM, REG_HWCAP2, 4) + FEAT_DEF(SVESHA3, REG_HWCAP2, 5) + FEAT_DEF(SVESM4, REG_HWCAP2, 6) + FEAT_DEF(FLAGM2, REG_HWCAP2, 7) + FEAT_DEF(FRINT, REG_HWCAP2, 8) + FEAT_DEF(SVEI8MM, REG_HWCAP2, 9) + FEAT_DEF(SVEF32MM, REG_HWCAP2, 10) + FEAT_DEF(SVEF64MM, REG_HWCAP2, 11) + FEAT_DEF(SVEBF16, REG_HWCAP2, 12) FEAT_DEF(AARCH64, REG_PLATFORM, 1) }; #endif /* RTE_ARCH */ -- 2.27.0
