So, the commit log message for the pahole patch is non-existent: https://github.com/iamkafai/pahole/commit/94a11b59e5920908085bfc8d24c92f95c8ffceaf we should do better in describing what is done and how, I'm staring with a message you sent to the kernel part: -- This patch introduces BPF Type Format (BTF). BTF (BPF Type Format) is the meta data format which describes the data types of BPF program/map. Hence, it basically focus on the C programming language which the modern BPF is primary using. The first use case is to provide a generic pretty print capability for a BPF map. -- Now I'm going to do the step-by-step guide on testing the feature just introduced, and will try to convert from dwarf to BTF and back, compare the pahole output for types encoded in DWARF and BTF, etc. If you have something ressembling this already, please share. Thanks, - Arnaldo
