30 DESCRIPTION
31 ===========
32 bpftool perf { show | list }
33 List all raw_tracepoint, tracepoint, kprobe attachment in the system.
34
35 Output will start with process id and file descriptor in that process,
36 followed by bpf program id, attachment information, and attachment point.
37 The attachment point for raw_tracepoint/tracepoint is the trace probe name.
38 The attachment point for k[ret]probe is either symbol name and offset, or a
39 kernel virtual address. The attachment point for u[ret]probe is the file
40 name and the file offset.
41
42 bpftool perf help
43 Print short help message.
