| |
Hi,
These patches augment the bpftool's map dump command with BTF info. In particular, when user runs `bpftool map dump [-j|-p] id <map-id>`, they will see map data formatted and tagged based upon BTF information associated with that map. Here is what each patch does:
Patch 1 exports BTF functions inside libbpf, to be used by patch 2.
Patch 2 adds btf_dumper which uses type info exported in patch 1 along with json_writer to json print or pretty json print map values alongside btf debug info.
Patch 3 uses btf_dumper to json or pretty print map values when -j or -p flag is specified to `btf map dump`.
Further details are included in patch descriptions.
Thanks, Okash
