      perf tools: Add time conversion event · 46bc29b9
      Adrian Hunter 提交于
      Intel PT uses the time members from the perf_event_mmap_page to convert
      between TSC and perf time.
      
      Due to a lack of foresight when Intel PT was implemented, those time
      members were recorded in the (implementation dependent) AUXTRACE_INFO
      event, the structure of which is generally inaccessible outside of the
      Intel PT decoder.  However now the conversion between TSC and perf time
      is needed when processing a jitdump file when Intel PT has been used for
      tracing.
      
      So add a user event to record the time members.  'perf record' will
      synthesize the event if the information is available.  And session
      processing will put a copy of the event on the session so that tools
      like 'perf inject' can easily access it.

      perf record: Apply config to BPF objects before recording · 8690a2a7
      Wang Nan 提交于
      bpf__apply_obj_config() is introduced as the core API to apply object
      config options to all BPF objects. This patch also does the real work
      for setting values for BPF_MAP_TYPE_PERF_ARRAY maps by inserting value
      stored in map's private field into the BPF map.
      
      This patch is required because we are not always able to set all BPF
      config during parsing. Further patch will set events created by perf to
      BPF_MAP_TYPE_PERF_EVENT_ARRAY maps, which is not exist until
      perf_evsel__open().
      
      bpf_map_foreach_key() is introduced to iterate over each key needs to be
      configured. This function would be extended to support more map types
      and different key settings.
      
      In perf record, before start recording, call bpf__apply_config() to turn
      on all BPF config options.

      perf record: Add record.build-id config option · 7a29c087
      Namhyung Kim 提交于
      Post processing at 'perf record' takes a long time on big machines.
      
      What it does is to find the build-id of binaries found in the event
      stream, so that it can make sure, at 'report' time, that the symtabs (be
      it ELF, kallsyms, etc) being used to resolve symbols are the ones
      matching the binaries found at 'record' time.
      
      Sometimes we just want to skip this processing of events at the end of
      the session to get quicker results, making sure the binaries haven't
      changed from 'record' to 'report' time.
      
      Add a new config option to control this behavior.
      
      The record.build-id config variable can have one of the following
      values:
      
       - cache: post-process data and save/update the binaries into the
                build-id cache (in ~/.debug).  This is the default.
       - no-cache: post-process the data but not update the build-id cache.
                   Same effect as using the -N option.
       - skip: skip post-processing and do not update the cache.
               Same effect as using the -B option.

      perf record: Support custom vmlinux path · 7efe0e03
      He Kuang 提交于
      Make perf-record command support --vmlinux option if BPF_PROLOGUE is on.
      
      'perf record' needs vmlinux as the source of DWARF info to generate
      prologue for BPF programs, so path of vmlinux should be specified.
      
      Short name 'k' has been taken by 'clockid'. This patch skips the short
      option name and uses '--vmlinux' for vmlinux path.

      perf tools: Make options always available, even if required libs not linked · 48e1cab1
      Wang Nan 提交于
      This patch keeps options of perf builtins same in all conditions. If
      one option is disabled because of compiling options, users should be
      notified.
      
      Masami suggested another implementation in [1] that, by adding a
      OPTION_NEXT_DEPENDS option before those options in the 'struct option'
      array, options parser knows an option is disabled. However, in some
      cases this array is reordered (options__order()). In addition, in
      parse-option.c that array is const, so we can't simply merge
      information in decorator option into the affacted option.
      
      This patch chooses a simpler implementation that, introducing a
      set_option_nobuild() function and two option parsing flags. Builtins
      with such options should call set_option_nobuild() before option
      parsing. The complexity of this patch is because we want some of options
      can be skipped safely. In this case their arguments should also be
      consumed.
      
      Options in 'perf record' and 'perf probe' are fixed in this patch.

      perf record: Synthesize COMM event for a command line workload · e803cf97
      Namhyung Kim 提交于
      When perf creates a new child to profile, the events are enabled on
      exec().  And in this case, it doesn't synthesize any event for the
      child since they'll be generated during exec().  But there's an window
      between the enabling and the event generation.
      
      It used to be overcome since samples are only in kernel (so we always
      have the map) and the comm is overridden by a later COMM event.
      However it won't work if events are processed and displayed before the
      COMM event overrides like in 'perf script'.  This leads to those early
      samples (like native_write_msr_safe) not having a comm but pid (like
      ':15328').
      
      So it needs to synthesize COMM event for the child explicitly before
      enabling so that it can have a correct comm.  But at this time, the
      comm will be "perf" since it's not exec-ed yet.

      perf record: Allow filtering perf's pid via --exclude-perf · 4ba1faa1
      Wang Nan 提交于
      This patch allows 'perf record' to exclude events issued by perf itself
      by '--exclude-perf' option.
      
      Before this patch, when doing something like:
      
       # perf record -a -e syscalls:sys_enter_write <cmd>
      
      One could easily get result like this:
      
       # /tmp/perf report --stdio
       ...
        # Overhead  Command  Shared Object       Symbol
        # ........  .......  ..................  ....................
        #
            99.99%  perf     libpthread-2.18.so  [.] __write_nocancel
            0.01%   ls       libc-2.18.so        [.] write
            0.01%   sshd     libc-2.18.so        [.] write
       ...
      
      Where most events are generated by perf itself.
      
      A shell trick can be done to filter perf itself out:
      
       # cat << EOF > ./tmp
       > #!/bin/sh
       > exec perf record -e ... --filter="common_pid != \$\$" -a sleep 10
       > EOF
       # chmod a+x ./tmp
       # ./tmp
      
      However, doing so is user unfriendly.
      
      This patch extracts evsel iteration framework introduced by patch 'perf
      record: Apply filter to all events in a glob matching' into
      foreach_evsel_in_last_glob(), and makes exclude_perf() function append
      new filter expression to each evsel selected by a '-e' selector.
      
      To avoid losing filters if user pass '--filter' after '--exclude-perf',
      this patch uses perf_evsel__append_filter() in both case, instead of
      perf_evsel__set_filter() which removes old filter. As a side effect, now
      it is possible to use multiple '--filter' option for one selector. They
      are combinded with '&&'.
