Arnaldo Carvalho de Melo spoke at the 2024
Linux Storage,
Filesystem, Memory Management, and BPF Summit
about his work on

Poke-a-hole (pahole),
a program that has expanded greatly over the years, but which was relevant to the
BPF track because it produces BPF Type Format (BTF) information from DWARF
debugging information. He covered some small changes to the program, and then
went into detail about the new support for data-type profiling. His
slides include
several examples.
