As a comparison, here are the test results with the BPF test suite kernel module: With the classic BPF JIT: test_bpf: Summary: 291 PASSED, 0 FAILED, [85/283 JIT'ed] and with the extended BPF JIT: test_bpf: Summary: 291 PASSED, 0 FAILED, [234/283 JIT'ed] As noted in patch 6, there are still a few more instructions to be JIT'ed. - Naveen _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
