Bug#973870: linux: Please consider enabling CONFIG_DEBUG_INFO_BTF
Hello, it would be great if this makes it into Bullseye. BTF is not only relevant for tracing but for all BPF-related tasks, including for example XDP. According to [1], most other distributions (Fedora 31+, RHEL 8.2+, Arch Linux, Ubuntu 20.10+) already enable BTF. Having this in the next Debian release would be very useful. I installed the dwarves package and tested building the linux source package with CONFIG_DEBUG_INFO_BTF and it worked fine.

Bug#973870: linux: Please consider enabling CONFIG_DEBUG_INFO_BTF
Package: linux Version: 5.9.1-1 Severity: wishlist Hi, it would be great if Debian kernels could also enable the CONFIG_DEBUG_INFO_BTF option, quoting from http://www.brendangregg.com/blog/2020-11-04/bpf-co-re-btf-libbpf.html: | CONFIG_DEBUG_INFO_BTF=y | | These new BPF binaries are only possible if this kernel config | option is set. It adds about 1.5 Mbytes to the kernel image (this is | tiny in comparison to DWARF debuginfo, which can be hundreds of | Mbytes). Ubuntu 20.10 has already made this config option the | default, and all other distros should follow. Note to distro | maintainers: it requires pahole >= 1.16. regards -mika-
