Subject: Re: arch: arm: bpf: Converting cBPF to eBPF for arm 32 bit
Hi Daniel and Kees,
Before I send the patch, I have tested the JIT compiler on ARMv7 but
not on ARMv5 or ARMv6. So can you tell me which arch versions I should
test it for?
Also for my testing, CONFIG_FRAME_POINTER and CONFIG_CPU_BIG_ENDIAN
are both disabled. But I need to test JIT with these flags as well.
Whenever I put these flags in .config file, the arm kernel is not
getting compiler with these flags. Can you tell me why? If you need
more information regarding this, please let me know.
With current config for ARMv7, benchmarks are :
