      perf header: Fixup reading of HEADER_NRCPUS feature · caa47047
      Arnaldo Carvalho de Melo authored
      The original patch introducing this header wrote the number of CPUs available
      and online in one order and then swapped those values when reading, fix it.
      
      Before:
      
        # perf record usleep 1
        # perf report --header-only | grep 'nrcpus \(online\|avail\)'
        # nrcpus online : 4
        # nrcpus avail : 4
        # echo 0 > /sys/devices/system/cpu/cpu2/online
        # perf record usleep 1
        # perf report --header-only | grep 'nrcpus \(online\|avail\)'
        # nrcpus online : 4
        # nrcpus avail : 3
        # echo 0 > /sys/devices/system/cpu/cpu1/online
        # perf record usleep 1
        # perf report --header-only | grep 'nrcpus \(online\|avail\)'
        # nrcpus online : 4
        # nrcpus avail : 2
      
      After the fix, bringing back the CPUs online:
      
        # perf report --header-only | grep 'nrcpus \(online\|avail\)'
        # nrcpus online : 2
        # nrcpus avail : 4
        # echo 1 > /sys/devices/system/cpu/cpu2/online
        # perf record usleep 1
        # perf report --header-only | grep 'nrcpus \(online\|avail\)'
        # nrcpus online : 3
        # nrcpus avail : 4
        # echo 1 > /sys/devices/system/cpu/cpu1/online
        # perf record usleep 1
        # perf report --header-only | grep 'nrcpus \(online\|avail\)'
        # nrcpus online : 4
        # nrcpus avail : 4

      Merge tag 'perf-urgent-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
      
      Pull perf/urgent fixes from Arnaldo Carvalho de Melo:
      
        - In some cases where perf_event.fork.{pid,tid} should be used we were instead
          using perf_event.comm.{pid,tid}, which is not a problem for for the 'pid'
          case, that sits in the same place in these union_perf_event members, but
          comm.tid sits where fork.ppid is, oops.
      
          These cases were considered as (potentially) problematic:
      
           - 'perf script' with !sample_id_all, i.e. only non old kernels without
              perf_event_attr.sample_id_all.
      
           - intel_pt could be affected when decoding without timestamps, as the exit
             event is only used to flush out data which anyway gets flushed at the
             end of the session.
      
           - intel_bts also uses the exit event to flush data which would probably not
             cause errors as it would get flushed at the end of the session instead.
      
          Fix it. (Adrian Hunter)
      
        - Due to relaxing the compiler checks for bison generated files, we missed
          updating one parse_events_add_pmu() caller when this function had its
          prototype changed, fix it. (Jiri Olsa)

      perf tools: Fix link time error with sample_reg_masks on non x86 · af4aeadd
      Stephane Eranian authored
      This patch makes perf compile on non x86 platforms by defining a weak
      symbol for sample_reg_masks[] in util/perf_regs.c.
      
      The patch also moves the REG() and REG_END() macros into the
      util/per_regs.h header file. The macros are renamed to
      SMPL_REG/SMPL_REG_END to avoid clashes with other header files.

      perf dwarf: Fix potential array out of bounds access · 3b27d139
      Wang Nan authored
      There is a problem in the dwarf-regs.c files for sh, sparc and x86 where
      it is possible to make an out-of-bounds array access when searching for
      register names.
      
      This patch fixes it by replacing '<=' to '<', so when register (number
      == XXX_MAX_REGS), get_arch_regstr() will return NULL.

       "The biggest change in this cycle is the rewrite of the main SMP load
        balancing metric: the CPU load/utilization.  The main goal was to make

          9d89c257 ("sched/fair: Rewrite runnable load and utilization average tracking")
      
        It is done in a way that significantly reduces complexity of the code:
      
          5 files changed, 249 insertions(+), 494 deletions(-)
      
        and the performance testing results are encouraging.  Nevertheless we
        need to keep an eye on potential regressions, since this potentially
        affects every SMP workload in existence.

         - Add support for using several Intel PT features (CYC, MTC packets),
           the relevant documentation was updated in:
               tools/perf/Documentation/intel-pt.txt
           briefly describing those packets, its purposes, how to configure
           them in the event config terms and relevant external documentation
           for further reading.  (Adrian Hunter)
      
         - Introduce support for probing at an absolute address, for user and
           kernel 'perf probe's, useful when one have the symbol maps on a
           developer machine but not on an embedded system.  (Wang Nan)
      
         - Add Intel BTS support, with a call-graph script to show it and PT
           in use in a GUI using 'perf script' python scripting with
           postgresql and Qt.  (Adrian Hunter)
      
         - Allow selecting the type of callchains per event, including
           disabling callchains in all but one entry in an event list, to save
           space, and also to ask for the callchains collected in one event to
           be used in other events.  (Kan Liang)
      
         - Beautify more syscall arguments in 'perf trace': (Arnaldo Carvalho
           de Melo)
             * A bunch more translate file/pathnames from pointers to strings.
             * Convert numbers to strings for the 'keyctl' syscall 'option'
               arg.
             * Add missing 'clockid' entries.
      
         - Introduce 'srcfile' sort key: (Andi Kleen)
      
             # perf record -F 10000 usleep 1
             # perf report --stdio --dsos '[kernel.vmlinux]' -s srcfile
             <SNIP>
             # Overhead  Source File
                26.49%  copy_page_64.S
                 5.49%  signal.c
                 0.51%  msr.h
             #
      
           It can be combined with other fields, for instance, experiment with
           '-s srcfile,symbol'.
      
           There are some oddities in some distros and with some specific
           DSOs, being investigated, so your mileage may vary.
      
         - Support per-event 'freq' term: (Namhyung Kim)
      
             $ perf record -e 'cpu/instructions,freq=1234/',cycles -c 1000 sleep 1
             $ perf evlist -F
             cpu/instructions,freq=1234/: sample_freq=1234
             cycles: sample_period=1000
             $
      
         - Deref sys_enter pointer args with contents from probe:vfs_getname,
           showing pathnames instead of pointers in many syscalls in 'perf
           trace'.  (Arnaldo Carvalho de Melo)
      
         - Stop collecting /proc/kallsyms in perf.data files, saving about
           4.5MB on a typical x86-64 system, use the the symbol resolution
           routines used in all the other tools (report, top, etc) now that we
           can ask libtraceevent to use perf's symbol resolution code.
           (Arnaldo Carvalho de Melo)
      
         - Allow filtering out of perf's PID via 'perf record --exclude-perf'.
           (Wang Nan)
      
         - 'perf trace' now supports syscall groups, like strace, i.e:
      
             $ trace -e file touch file
      
           Will expand 'file' into multiple, file related, syscalls.  More
           work needed to add extra groups for other syscall groups, and also
           to complement what was added for the 'file' group, included as a
           proof of concept.  (Arnaldo Carvalho de Melo)
      
         - Add lock_pi stresser to 'perf bench futex', to test the kernel code
           related to FUTEX_(UN)LOCK_PI.  (Davidlohr Bueso)
      
         - Let user have timestamps with per-thread recording in 'perf record'
           (Adrian Hunter)
      
         - ... and tons of other changes, see the shortlog and the Git log for
           details"

      Pull RCU updates from Ingo Molnar:
       "The main RCU changes in this cycle are:
      
         - the combination of tree geometry-initialization simplifications and

      Pull regulator updates from Mark Brown:
       "The biggest changes in the core this time around have been some
        refactorings that move us towards being able to drop the list of
        regulators maintained by the core and instead just use the driver
        model list maintained for the class devices for regulators which will
        make the code smaller and avoid some potential bugs.
      
        Otherwise another fairly quiet release for the regulator API,
        highlights include:
      
         - a new API for setting voltages based on a minimum, target, maximum
           triplet
      
         - support for continuous voltage ranges rather than tables of
           explicit steps in the PWM regulator, requiring less explicit
           configuration
