      perf: Make perf build for x86 with UAPI disintegration applied · d2709c7c
      David Howells authored
      Make perf build for x86 once the UAPI disintegration patches for that arch
      have been applied by adding the appropriate -I flags - in the right order -
      and then converting some #includes that use ../.. notation to find main kernel
      headerfiles to use <asm/foo.h> and <linux/foo.h> instead.
      
      Note that -Iarch/foo/include/uapi is present _before_ -Iarch/foo/include.
      This makes sure we get the userspace version of the pt_regs struct.  Ideally,
      we wouldn't have the latter -I flag at all, but unfortunately we want
      asm/svm.h and asm/vmx.h in builtin-kvm.c and these aren't part of the UAPI -
      at least not for x86.  I wonder if the bits outside of the __KERNEL__ guards
      *should* be transferred there.
      
      I note also that perf seems to do its dependency handling manually by listing
      all the header files it might want to use in LIB_H in the Makefile.  Can this
      be changed to use -MD?
      
      Note that to do make this work, we need to export and UAPI disintegrate
      linux/hw_breakpoint.h, which I think should've been exported previously so that
      perf can access the bits.  We have to do this in the same patch to maintain
      bisectability.

      perf evlist: Rename __group method to __set_leader · 63dab225
      Arnaldo Carvalho de Melo authored
      Just like was done for parse_events__set_leader.
      
      Also we need to have the list_entry set_leader method in evlist.c so that we
      don't grow another dep in the python binding:
      
       # ~acme/git/linux/tools/perf/python/twatch.py
       Traceback (most recent call last):
         File "/home/acme/git/linux/tools/perf/python/twatch.py", line 16, in <module>
           import perf
       ImportError: /home/acme/git/build/perf/python/perf.so: undefined symbol: parse_events__set_leader
      
      And also remove a pr_debug from evsel.c so that we avoid this one too:
      
       # ~acme/git/linux/tools/perf/python/twatch.py
       Traceback (most recent call last):

      perf tools: Enable grouping logic for parsed events · 6a4bb04c
      Jiri Olsa authored
      This patch adds a functionality that allows to create event groups
      based on the way they are specified on the command line. Adding
      functionality to the '{}' group syntax introduced in earlier patch.
      
      The current '--group/-g' option behaviour remains intact. If you
      specify it for record/stat/top command, all the specified events
      become members of a single group with the first event as a group
      leader.
      
      With the new '{}' group syntax you can create group like:
        # perf record -e '{cycles,faults}' ls
      
      resulting in single event group containing 'cycles' and 'faults'
      events, with cycles event as group leader.
      
      All groups are created with regards to threads and cpus. Thus
      recording an event group within a 2 threads on server with
      4 CPUs will create 8 separate groups.
      
      Examples (first event in brackets is group leader):
      
        # 1 group (cpu-clock,task-clock)
        perf record --group -e cpu-clock,task-clock ls
        perf record -e '{cpu-clock,task-clock}' ls
      
        # 2 groups (cpu-clock,task-clock) (minor-faults,major-faults)
        perf record -e '{cpu-clock,task-clock},{minor-faults,major-faults}' ls
      
        # 1 group (cpu-clock,task-clock,minor-faults,major-faults)
        perf record --group -e cpu-clock,task-clock -e minor-faults,major-faults ls
        perf record -e '{cpu-clock,task-clock,minor-faults,major-faults}' ls
      
        # 2 groups (cpu-clock,task-clock) (minor-faults,major-faults)
        perf record -e '{cpu-clock,task-clock} -e '{minor-faults,major-faults}' \
         -e instructions ls
      
        # 1 group
        # (cpu-clock,task-clock,minor-faults,major-faults,instructions)
        perf record --group -e cpu-clock,task-clock \
         -e minor-faults,major-faults -e instructions ls perf record -e
      '{cpu-clock,task-clock,minor-faults,major-faults,instructions}' ls
      
      It's possible to use standard event modifier for a group, which spans
      over all events in the group and updates each event modifier settings,
      for example:
      
        # perf record -r '{faults:k,cache-references}:p'
      
      resulting in ':kp' modifier being used for 'faults' and ':p' modifier
      being used for 'cache-references' event.

      perf tools: Add support to update event modifier · f5b1135b
      Jiri Olsa authored
      Adding support to update already defined event's attribute with
      event modifier. This change will allow to use group modifier as
      an update to the existing event modifiers.
      
      Adding 'add' parameter to the parse_events__modifier_event function.
      Calling it with 'add' = false/true, the event modifier is
      initialized/updated respectively.
      
      Added exclude_GH flag to evsel struct, because we need to remember
      if one of 'GH' modifiers was used for event. The reason is that the
      default settings for exclude_guest is 1 and during the group
      modifier processing we have no other way of knowing if it was set
      by default or by event modifier.
      
      Keeping the current behaviour, that any event/group modifier reset
      the defaults for exclude_host (0) and exclude_guest (1).

      perf tools: Add support to parse event group syntax · 89efb029
      Jiri Olsa authored
      Adding scanner/parser bits to parse event groups.
      
      The grammar for group is:
        groups:      groups ',' group | group
        group:       group_name '{' events '}' group_mod
        group_name:  name | empty
        group_mod:   ':' group_mods | empty
        group_mods:  event_mod
      
      It's possible to use standard event modifier as a modifier
      for group. It'll be used as an update to existing event
      modifiers.
      
      It's necessary to use quoting ("'\) when specifying group on
      command line, since {} characters are interpreted by most of
      the shells.
      
      It is now possible to specify groups in event syntax like:
      
        '{cycles,faults}'
         - anonymous group
      
        'group1{cycles,faults}
         - group with name 'group1'
      
        '{cycles,faults}:k
         - anonymous group with event modifier 'k'
      
        '{cpu-clock,task-clock},{minor-faults,major-faults}'
         - two anonymous groups
      
      The grouping functionality itself is coming shortly.

      perf tools: Add support to specify pmu style event · 5f537a26
      Jiri Olsa authored
      Added new event rule to the event definition grammar:
      
      event_def: event_pmu |
                 ...
      event_pmu: PE_NAME '/' event_config '/'
      
      Using this rule, event could be now specified like:
        cpu/config=1,config1=2,config2=3/u
      
      where pmu name 'cpu' is looked up via following path:
        ${sysfs_mount}/bus/event_source/devices/${pmu}
      
      and config options are bound to the pmu's format definiton:
        ${sysfs_mount}/bus/event_source/devices/${pmu}/format
      
      The hardcoded config options still stays and have precedence
      over any format field defined with same name.

      perf tools: Add config options support for event parsing · 8f707d84
      Jiri Olsa authored
      Adding a new rule to the event grammar to be able to specify
      values of additional attributes of symbolic event.
      
      The new syntax for event symbolic definition is:
      
      event_legacy_symbol:  PE_NAME_SYM '/' event_config '/' |
                            PE_NAME_SYM sep_slash_dc
      
      event_config:         event_config ',' event_term | event_term
      
      event_term:           PE_NAME '=' PE_NAME |
                            PE_NAME '=' PE_VALUE
                            PE_NAME
      
      sep_slash_dc: '/' | ':' |
      
      At the moment the config options are hardcoded to be used for legacy
      symbol events to define several perf_event_attr fields. It is:
      
        'config'   to define perf_event_attr::config
        'config1'  to define perf_event_attr::config1
        'config2'  to define perf_event_attr::config2
        'period'   to define perf_event_attr::sample_period
      
      Legacy events could be now specified as:
        cycles/period=100000/
      
      If term is specified without the value assignment, then 1 is
      assigned by default.

      Added flex/bison files for event grammar parsing. The generated
      parser is part of the patch. Added makefile rule 'event-parser'
      to generate the parser code out of the bison/flex sources.

      perf tools: Simplify debugfs mountpoint handling code · ebf294bf
      Arnaldo Carvalho de Melo authored
      We don't need to have two PATH_MAX char sized arrays holding it, just
      one in util/debugfs.c will do.
      
      Also rename debugfs_path to tracing_events_path, as it is not the path
      to debugfs, that is debugfs_mountpoint. Both are now accessible.
      
      This will allow accessing this code in the perf python binding without
      having to drag in perf.c and util/parse-events.c.
      
      The defaults for these variables are the canonical "/sys/kernel/debug"
      and "/sys/kernel/debug/tracing/events/", removing the need for simple
      tools to call debugfs_mount(NULL).

      perf evsel: Introduce perf_evlist · 361c99a6
      Arnaldo Carvalho de Melo authored
      Killing two more perf wide global variables: nr_counters and evsel_list
      as a list_head.
      
      There are more operations that will need more fields in perf_evlist,
      like the pollfd for polling all the fds in a list of evsel instances.
      
      Use option->value to pass the evsel_list to parse_{events,filters}.

      perf tools: Fix perf_event.h header usage · d030260a
      Stephane Eranian authored
      This patch fixes the usage of the perf_event.h header file
      between command modules and the supporting code in util.
      
      It is necessary to ensure that ALL files use the SAME
      perf_event.h header from the kernel source tree.
      
      There were a couple of #include <linux/perf_event.h> mixed
      with #include "../../perf_event.h".
      
      This caused issues on some distros because of mismatch
      in the layout of struct perf_event_attr. That eventually
      led perf stat to segfault.
