From 350a62ca065be252ababc43a7c96f8aca390a18f Mon Sep 17 00:00:00 2001 From: Tiezhu Yang Date: Fri, 23 Apr 2021 09:23:30 +0800 Subject: [PATCH] bpf: Document the pahole release info related to libbpf in bpf_devel_QA.rst pahole starts to use libbpf definitions and APIs since v1.13 after the commit 21507cd3e97b ("pahole: add libbpf as submodule under lib/bpf"). It works well with the git repository because the libbpf submodule will use "git submodule update --init --recursive" to update. Unfortunately, the default github release source code does not contain libbpf submodule source code and this will cause build issues, the tarball from https://git.kernel.org/pub/scm/devel/pahole/pahole.git/ is same with github, you can get the source tarball with corresponding libbpf submodule codes from https://fedorapeople.org/~acme/dwarves This change documents the above issues to give more information so that we can get the tarball from the right place, early discussion is here: https://lore.kernel.org/bpf/2de4aad5-fa9e-1c39-3c92-9bb9229d0966@loongson.cn/ Signed-off-by: Tiezhu Yang Signed-off-by: Alexei Starovoitov Reviewed-by: Arnaldo Carvalho de Melo Link: https://lore.kernel.org/bpf/1619141010-12521-1-git-send-email-yangtiezhu@loongson.cn --- Documentation/bpf/bpf_devel_QA.rst | 13 +++++++++++++ 1 file changed, 13 insertions(+) diff --git a/Documentation/bpf/bpf_devel_QA.rst b/Documentation/bpf/bpf_devel_QA.rst index d05e67e72c10..253496af8fef 100644 --- a/Documentation/bpf/bpf_devel_QA.rst +++ b/Documentation/bpf/bpf_devel_QA.rst @@ -449,6 +449,19 @@ from source at https://github.com/acmel/dwarves +pahole starts to use libbpf definitions and APIs since v1.13 after the +commit 21507cd3e97b ("pahole: add libbpf as submodule under lib/bpf"). +It works well with the git repository because the libbpf submodule will +use "git submodule update --init --recursive" to update. + +Unfortunately, the default github release source code does not contain +libbpf submodule source code and this will cause build issues, the tarball +from https://git.kernel.org/pub/scm/devel/pahole/pahole.git/ is same with +github, you can get the source tarball with corresponding libbpf submodule +codes from + +https://fedorapeople.org/~acme/dwarves + Some distros have pahole version 1.16 packaged already, e.g. Fedora, Gentoo.
