^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) 	**bpftool perf { show | list }**
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) 		  List all raw_tracepoint, tracepoint, kprobe attachment in the system.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) 		  Output will start with process id and file descriptor in that process,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) 		  followed by bpf program id, attachment information, and attachment point.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) 		  The attachment point for raw_tracepoint/tracepoint is the trace probe name.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) 		  The attachment point for k[ret]probe is either symbol name and offset,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) 		  or a kernel virtual address.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) 		  The attachment point for u[ret]probe is the file name and the file offset.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) 	**bpftool perf help**
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) 		  Print short help message.
