BTFhub, in collaboration with the BTFhub Archive repository, supplies BTF files for all published kernels that lack native support for embedded BTF. This joint effort ensures that even kernels without built-in BTF support can effectively leverage the benefits of eBPF programs, promoting compatibility across various kernel versions.
