| |
When the -D option is used, the details of thread-map, cpu-map and event-update events are not currently dumped. Add prints so that they are.
Example:
# perf record --kcore sleep 0.1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.021 MB perf.data (7 samples) ] # perf script -D | grep 'THREAD\|CPU' 0 0x4950 [0x28]: PERF_RECORD_THREAD_MAP nr: 1 thread: 35116 0 0x4978 [0x20]: PERF_RECORD_CPU_MAP: 0-7 # perf script -D | grep -A4 'UPDATE' 0 0x4920 [0x30]: PERF_RECORD_EVENT_UPDATE ... id: 147 ... 0-7
