From: Jerin Jacob <jer...@marvell.com> Added eBPF arm64 JIT support to improve the eBPF program performance on arm64.
dpdk.org/examples/bpf/t1.c application shows around 50% improvement on OCTEON TX2 platform in JIT vs interpreter mode. Verified the implementation using existing bpf_autotest application. # echo "bpf_autotest" | sudo ./build/app/test -c 0x3 RTE>>bpf_autotest run_test(test_store1) start run_test(test_store2) start run_test(test_load1) start run_test(test_ldimm1) start run_test(test_mul1) start run_test(test_shift1) start run_test(test_jump1) start run_test(test_alu1) start run_test(test_bele1) start run_test(test_xadd1) start run_test(test_div1) start bpf_exec(0xffffa37c0000): division by 0 at pc: 0x68; run_test(test_call1) start run_test(test_call2) start run_test(test_call3) start Test OK Jerin Jacob (8): bpf/arm64: add build infrastructure bpf/arm64: add prologue and epilogue bpf/arm64: add basic arithmetic operations bpf/arm64: add logical operations bpf/arm64: add byte swap operations bpf/arm64: add load and store operations bpf/arm64: add atomic-exchange-and-add operation bpf/arm64: add branch operation MAINTAINERS | 1 + doc/guides/prog_guide/bpf_lib.rst | 2 +- doc/guides/rel_notes/release_19_11.rst | 5 + lib/librte_bpf/Makefile | 2 + lib/librte_bpf/bpf.c | 4 +- lib/librte_bpf/bpf_impl.h | 3 +- lib/librte_bpf/bpf_jit_arm64.c | 1451 ++++++++++++++++++++++++ lib/librte_bpf/meson.build | 2 + 8 files changed, 1466 insertions(+), 4 deletions(-) create mode 100644 lib/librte_bpf/bpf_jit_arm64.c -- 2.23.0
