perf script: Add --show-bpf-events to show eBPF related events
Add the --show-bpf-events command line option to show the eBPF related events:
PERF_RECORD_KSYMBOL
PERF_RECORD_BPF_EVENT
Usage:
# perf record -a
...
# perf script --show-bpf-events
...
swapper 0 [000] 0.000000: PERF_RECORD_KSYMBOL ksymbol event with addr ffffffffc0ef971d len 229 type 1 flags 0x0 name bpf_prog_2a142ef67aaad174
swapper 0 [000] 0.000000: PERF_RECORD_BPF_EVENT bpf event with type 1, flags 0, id 36
...
