Subject: Re: [PATCH v2] arm: eBPF JIT compiler

Hi Kees,

Problem is my ARM machine don't have clang and iproute2 which is
keeping me from testing the bpf tail calls.

You should do the following to test it,.

1. tools/testing/selftests/bpf/
2. make
3. sudo ./test_progs

And, before testing, you have to do "make headers_install".
These tests are for tail calls with the attached patch. If its too
much work, Can you please upload your arm image so that I can test it?
I just need a good machine.
