The JIT compiler emits A64 instructions. It supports eBPF only. Legacy BPF is supported thanks to conversion by BPF core. JIT is enabled in the same way as for other architectures: echo 1 > /proc/sys/net/core/bpf_jit_enable Or for additional compiler output: echo 2 > /proc/sys/net/core/bpf_jit_enable See Documentation/networking/filter.txt for more information. The implementation passes all 57 tests in lib/test_bpf.c on ARMv8 Foundation Model :) Also tested by Will on Juno platform.
