Subject: Re: [PATCH bpf-next 1/3] bpf, riscv: add BPF JIT for RV64G

Date: Sun,  3 Feb 2019 12:51:29 +0100

> From: Björn Töpel <>
> This commit adds BPF JIT for RV64G.
> The JIT is a two-pass JIT, and has a dynamic prolog/epilogue (similar
> to the MIPS64 BPF JIT) instead of static ones (e.g. x86_64).
> At the moment the RISC-V Linux port does not support HAVE_KPROBES,
> which means that CONFIG_BPF_EVENTS is not supported. Thus, no tests
> involving BPF_PROG_TYPE_TRACEPOINT passes.
> Further, the implementation does not support "far branching" (>4KiB).
> The implementation passes all the test_bpf.ko tests:
>   test_bpf: Summary: 378 PASSED, 0 FAILED, [366/366 JIT'ed]
> All the tail_call tests in the selftest/bpf/test_verifier program
> passes.
> All tests where done on QEMU (QEMU emulator version 3.1.50
> (v3.1.0-688-g8ae951fbc106)).
