      perf trace: Fix build when DWARF unwind isn't available · ccd62a89
      Arnaldo Carvalho de Melo authored
      The variable is initialized and then conditionally set to a different
      value, but not used when DWARF unwinding is not available, bummer, write
      1000 times: "Run make -C tools/perf build-test"...
      
        builtin-trace.c: In function ‘cmd_trace’:
        builtin-trace.c:3112:6: error: variable ‘max_stack_user_set’ set but not
        used [-Werror=unused-but-set-variable]
          bool max_stack_user_set = true;
              ^
        cc1: all warnings being treated as err
      
      Fix it by marking it as __maybe_unused.

      Merge tag 'perf-core-for-mingo-20160415' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
      
      Pull perf/core improvements from Arnaldo Carvalho de Melo:
      
      User visible changes:
      
      - Wire the callchain unwinding "max-stack" now to 'perf script --max-stack',
        allowing to limit the depth of callchains, possibly reducing processing
        time (Arnaldo Carvalho de Melo)
      
      - Ditto for 'perf trace --max-stack' (Arnaldo Carvalho de Melo)
      
      - Introduce a --min-stack filter for 'perf trace', to show syscalls that
        had a userspace callchain leading to it at least min-stack deep (Arnaldo Carvalho de Melo)
      
      - Make 'perf trace' work with multiple threads and the --duration filter,
        i.e. do not print the start of an interrupted syscall followed by ...
        to print interrupts from other threads, as we need to wait the sys_exit
        syscall tracepoint to calculate the duration, duh. (Arnaldo Carvalho de Melo)
      
        System wide --duration now works as expected:
      
         [root@jouet ~]# trace --duration 100
           152.393 (145.147 ms): Timer/24358 futex(uaddr: 0x7f5ed98e56cc, op: WAIT_BITSET|PRIV|CLKRT, val: 7055125, utime: 0x7f5ecdbfec30, val3: 4294967295) = -1 ETIMEDOUT Connection timed out
           152.438 (145.040 ms): firefox/24321 poll(ufds: 0x7f5ec388b460, nfds: 6, timeout_msecs: 4294967295) = 1
           358.580 (158.279 ms): Xorg/2025 select(n: 512, inp: 0x83a8e0, tvp: 0x7ffdcbb63610) = 0 Timeout
           358.687 (148.285 ms): gnome-terminal/2711 poll(ufds: 0x55b7e6811ad0, nfds: 15, timeout_msecs: 249) = 1

      - Now 'perf trace's --max-stack and --min-stack will automatically set
        "--call-graph dwarf", if --call-graph is not present on the command line:
      
         [root@jouet ~]# perf trace -e nanosleep --max-stack 3 usleep 1
           0.299 ( 0.057 ms): usleep/29658 nanosleep(rqtp: 0x7fff80f3b230) = 0
                                             __nanosleep+0x10 (/usr/lib64/libc-2.22.so)
                                             usleep+0x34 (/usr/lib64/libc-2.22.so)
                                             main+0x1eb (/usr/bin/usleep)
         [root@jouet ~]#
      
      - Bump 'perf trace --mmap-pages' for root when using callchains and not
        specifying --mmap-pages explicitely (Arnaldo Carvalho de Melo)
      
      Build fixes:
      
      - The python binding object had missing symbols, to some refactoring
        to fix that (Arnaldo Carvalho de Melo)

      perf trace: Bump --mmap-pages when --call-graph is used by the root user · f3e459d1
      Arnaldo Carvalho de Melo authored
      To reduce the chances we'll overflow the mmap buffer, manual fine tuning
      trumps this.

      perf evlist: Expose perf_event_mlock_kb_in_pages() helper · f5e7150c
      Arnaldo Carvalho de Melo authored
      When the user doesn't set --mmap-pages, perf_evlist__mmap() will do it
      by reading the maximum possible for a non-root user from the
      /proc/sys/kernel/perf_event_mlock_kb file.
      
      Expose that function so that 'perf trace' can, for root users, to bump
      mmap-pages to a higher value for root, based on the contents of this
      proc file.

      perf trace: Make --(min,max}-stack imply "--call-graph dwarf" · 05614993
      Arnaldo Carvalho de Melo authored
      If one uses:
      
        # perf trace --min-stack 16
      
      Then it implicitly means that callgraphs should be enabled, and the best
      option in terms of widespread availability is "dwarf".
      
      Further work needed to choose a better alternative, LBR, in capable
      systems.

      To be able to call it outside option parsing, like when setting a
      default --call-graph parameter in 'perf trace' when just --min-stack is
      used.

      perf trace: Introduce --min-stack filter · 5cf9c84e
      Arnaldo Carvalho de Melo authored
      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

      perf trace: Do not print interrupted syscalls when using --duration · e519bd9a
      Arnaldo Carvalho de Melo authored
      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.

      - Allow requesting that some CPUs or PIDs be highlighted in 'perf sched map' (Jiri Olsa)
      
      - Compact 'perf sched map' to show just CPUs with activity, improving the output
        in high core count systems (Jiri Olsa)
      
      - Fix segfault with 'perf trace --no-syscalls -e syscall-names' by bailing out
        such request, doesn't make sense to ask for no syscalls and then specify which
        ones should be printed (Arnaldo Carvalho de Melo)
