Subject: [bug#70962] [PATCH 12/14] gnu: linux-libre: Enable BTF debug info.
Date: Wed, 15 May 2024 12:57:22 -0400 [thread overview]
Message-ID: <0ef662fff82aa5034e95f41ff413c06355a0fd70.1715791830.git.maxim.cournoyer@gmail.com> (raw)
In-Reply-To: <7cf609dcf83c85b6897c9fb9af46ce8a854a15c8.1715791830.git.maxim.cournoyer@gmail.com>
This is needed for software making use of eBPF programs, such as the sysdig
utility, among others. For more information about BPF, see:
<https://brendangregg.com/blog/2020-11-04/bpf-co-re-btf-libbpf.html>.
* gnu/packages/linux.scm (%default-extra-linux-options): Enable
CONFIG_DEBUG_INFO, CONFIG_DEBUG_INFO_BTF,
CONFIG_DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT, CONFIG_BPF_JIT,
CONFIG_BPF_JIT_ALWAYS_ON, CONFIG_BPF_SYSCALL and BPF_UNPRIV_DEFAULT_OFF.
Disable CONFIG_DEBUG_INFO_REDUCED.
(make-linux-libre*) [native-inputs]: Add dwarves, python-wrapper and zlib.
