An Update on Pahole
update on pahole Pahole (originally "Poke-a-hole") is a Swiss Army knife for exploring and editing debug information. Pahole is also currently involved in the kernel's build process to rearrange the information produced by various compilers into a form useful to the BPF verifier, although there are plans to render it unnecessary.
Pahole is also currently involved in the kernel's build process to rearrange the information produced by various compilers into a form useful to the BPF verifier, although there are plans to render it unnecessary. Pahole maintainer Arnaldo Carvalho de Melo shared some status updates about the project at the 2025 Linux Storage, Filesystem, Memory-Management, and BPF Summit. That answer seemed to please Starovoitov, who thought that having compilers generate BTF natively, without using pahole to convert debugging information from DWARF format, would be a substantial speedup.
