2023-03-14perf tools bpf: Add vmlinux.h to .gitignoreArnaldo Carvalho de Melo1-1/+2
Now that BPF skel based tools will be built by default if the toolchain pieces that are needed are available, building directly on the source tree will produce a vmlinux.h from the BTF info that needs to get ignored. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2021-01-15perf build: Support build BPF skeletons with perfSong Liu1-0/+3
BPF programs are useful in perf to profile BPF programs. BPF skeleton is by far the easiest way to write BPF tools. Enable building BPF skeletons in util/bpf_skel. A dummy bpf skeleton is added. More bpf skeletons will be added for different use cases.
