A time out is needed in such cases. 206 This option sets the time out limit. The default value is 500 ms. 207 208--sort-events:: 209 Do sorting on batches of events, use when noticing out of order events that 210 may happen, for instance, when a thread gets migrated to a different CPU 211 while processing a syscall. 212 | 1perf-trace(1) 2============= 3 4NAME 5---- 6perf-trace - strace inspired tool 7 8SYNOPSIS --- 196 unchanged lines hidden (view full) --- 205 because the file may be huge.

| 213--map-dump:: 214 Dump BPF maps setup by events passed via -e, for instance the augmented_raw_syscalls 215 living in tools/perf/examples/bpf/augmented_raw_syscalls.c. For now this 216 dumps just boolean map values and integer keys, in time this will print in hex 217 by default and use BTF when available, as well as use functions to do pretty 218 printing using the existing 'perf trace' syscall arg beautifiers to map integer 219 arguments to strings (pid to comm, syscall id to syscall name, etc). |
