Hi, I am starting this thread to know if someone is implementing the BPF dispatcher for ARM64 and if not, what would be needed to make this happen. The basic infra + x86 specific code was introduced in [1] by Björn Töpel. To make BPF dispatcher work on ARM64, the arch_prepare_bpf_dispatcher() has to be implemented in arch/arm64/net/bpf_jit_comp.c. As I am not well versed with XDP and the JIT, I have a few questions regarding this. 1. What is the best way to test this? Is there a selftest that will fail now and will pass once the dispatcher is implemented? 2. As there is no CONFIG_RETPOLINE in ARM64, will the dispatcher be useful.
