      perf trace: Introduce --min-stack filter · 5cf9c84e
      Arnaldo Carvalho de Melo 提交于
      Counterpart to --max-stack, to help focusing on deeply nested calls. Can
      be combined with --duration, etc.
      
      E.g.:
      
        System wide syscall tracing looking for call stacks longer than 66:
      
        # trace --mmap-pages 32768 --filter-pid 2711 --call-graph dwarf,16384 --min-stack 66
      
        Or more compactly:
      
        # trace -m 32768 --filt 2711 --call dwarf,16384 --min-st 66

    • A
      perf trace: Do not print interrupted syscalls when using --duration · e519bd9a
      Arnaldo Carvalho de Melo 提交于
      With multiple threads, e.g. a system wide trace session, and one syscall is
      midway in a thread and another thread starts another syscall we must print the
      start of the interrupted syscall followed by ..., but that can't be done that
      way when we use the --duration filter, as we have to wait for the syscall exit
      to calculate the duration and decide if it should be filtered, so we have to
      disable the interrupted logic and only print at syscall exit, duh.
      
      Before:
      
        # trace --duration 100
