      perf: Do the big rename: Performance Counters -> Performance Events · cdd6c482
      Ingo Molnar 提交于
      Bye-bye Performance Counters, welcome Performance Events!
      
      In the past few months the perfcounters subsystem has grown out its
      initial role of counting hardware events, and has become (and is
      becoming) a much broader generic event enumeration, reporting, logging,
      monitoring, analysis facility.
      
      Naming its core object 'perf_counter' and naming the subsystem
      'perfcounters' has become more and more of a misnomer. With pending
      code like hw-breakpoints support the 'counter' name is less and
      less appropriate.
      
      All in one, we've decided to rename the subsystem to 'performance
      events' and to propagate this rename through all fields, variables
      and API names. (in an ABI compatible fashion)
      
      The word 'event' is also a bit shorter than 'counter' - which makes
      it slightly more convenient to write/handle as well.
      
      Thanks goes to Stephane Eranian who first observed this misnomer and
      suggested a rename.
      
      User-space tooling and ABI compatibility is not affected - this patch
      should be function-invariant. (Also, defconfigs were not touched to
      keep the size down.)
      
      This patch has been generated via the following script:
      
        FILES=$(find * -type f | grep -vE 'oprofile|[^K]config')
      
        sed -i \
          -e 's/PERF_EVENT_/PERF_RECORD_/g' \
          -e 's/PERF_COUNTER/PERF_EVENT/g' \
          -e 's/perf_counter/perf_event/g' \
          -e 's/nb_counters/nb_events/g' \
          -e 's/swcounter/swevent/g' \
          -e 's/tpcounter_event/tp_event/g' \
          $FILES
      
        for N in $(find . -name perf_counter.[ch]); do
          M=$(echo $N | sed 's/perf_counter/perf_event/g')
          mv $N $M
        done
      
        FILES=$(find . -name perf_event.*)
      
        sed -i \
          -e 's/COUNTER_MASK/REG_MASK/g' \
          -e 's/COUNTER/EVENT/g' \
          -e 's/\<event\>/event_id/g' \
          -e 's/counter/event/g' \
          -e 's/Counter/Event/g' \
          $FILES
      
      ... to keep it as correct as possible. This script can also be
      used by anyone who has pending perfcounters patches - it converts
      a Linux kernel tree over to the new naming. We tried to time this
      change to the point in time where the amount of pending patches
      is the smallest: the end of the merge window.
      
      Namespace clashes were fixed up in a preparatory patch - and some
      stylistic fallout will be fixed up in a subsequent patch.
      
      ( NOTE: 'counters' are still the proper terminology when we deal
        with hardware registers - and these sed scripts are a bit
        over-eager in renaming them. I've undone some of that, but
        in case there's something left where 'counter' would be
        better than 'event' we can undo that on an individual basis
        instead of touching an otherwise nicely automated patch. )

      perf_counter: Rename list_entry -> group_entry, counter_list -> group_list · 65abc865
      Ingo Molnar 提交于
      This is in preparation of the big rename, but also makes sense
      in a standalone way: 'list_entry' is a bad name as we already
      have a list_entry() in list.h.
      
      Also, the 'counter list' is too vague, it doesnt tell us the
      purpose of that list.

      Frederic Weisbecker 提交于
      This patch implements the kernel side support for ftrace event
      record sampling.
      
      A new counter sampling attribute is added:
      
         PERF_SAMPLE_TP_RECORD
      
      which requests ftrace events record sampling. In this case
      if a PERF_TYPE_TRACEPOINT counter is active and a tracepoint
      fires, we emit the tracepoint binary record to the
      perfcounter event buffer, as a sample.
      
      Result, after setting PERF_SAMPLE_TP_RECORD attribute from perf
      record:

      What will come next?
      
       - Userspace support ('perf trace'), 'flight data recorder' mode
         for perf trace, etc.
      
       - The unconditional copy from the profiling callback brings
         some costs however if someone wants no such sampling to
         occur, and needs to be fixed in the future. For that we need
         to have an instant access to the perf counter attribute.
         This is a matter of a flag to add in the struct ftrace_event.
      
       - Take care of the events recursivity! Don't ever try to record
         a lock event for example, it seems some locking is used in
         the profiling fast path and lead to a tracing recursivity.
         That will be fixed using raw spinlock or recursivity
         protection.

      after the task's counters have been closed.

      perf_counter: PERF_SAMPLE_ID and inherited counters · 7f453c24
      Peter Zijlstra 提交于
      Anton noted that for inherited counters the counter-id as provided by
      PERF_SAMPLE_ID isn't mappable to the id found through PERF_RECORD_ID
      because each inherited counter gets its own id.
      
      His suggestion was to always return the parent counter id, since that
      is the primary counter id as exposed. However, these inherited
      counters have a unique identifier so that events like
      PERF_EVENT_PERIOD and PERF_EVENT_THROTTLE can be specific about which
      counter gets modified, which is important when trying to normalize the
      sample streams.
      
      This patch removes PERF_EVENT_PERIOD in favour of PERF_SAMPLE_PERIOD,
      which is more useful anyway, since changing periods became a lot more
      common than initially thought -- rendering PERF_EVENT_PERIOD the less
      useful solution (also, PERF_SAMPLE_PERIOD reports the more accurate
      value, since it reports the value used to trigger the overflow,
      whereas PERF_EVENT_PERIOD simply reports the requested period changed,
      which might only take effect on the next cycle).
      
      This still leaves us PERF_EVENT_THROTTLE to consider, but since that
      _should_ be a rare occurrence, and linking it to a primary id is the
      most useful bit to diagnose the problem, we introduce a
      PERF_SAMPLE_STREAM_ID, for those few cases where the full
      reconstruction is important.

      perf_counter: Simplify and fix task migration counting · e5289d4a
      Peter Zijlstra 提交于
      The task migrations counter was causing rare and hard to decypher
      memory corruptions under load. After a day of debugging and bisection
      we found that the problem was introduced with:
      
        3f731ca6: perf_counter: Fix cpu migration counter
      
      Turning them off fixes the crashes. Incidentally, the whole
      perf_counter_task_migration() logic can be done simpler as well,
      by injecting a proper sw-counter event.
      
      This cleanup also fixed the crashes. The precise failure mode is
      not completely clear yet, but we are clearly not unhappy about
      having a fix ;-)

      perf_counter: Make callchain samples extensible · f9188e02
      Peter Zijlstra 提交于
      Before exposing upstream tools to a callchain-samples ABI, tidy it
      up to make it more extensible in the future:
      
      Use markers in the IP chain to denote context, use (u64)-1..-4095 range
      for these context markers because we use them for ERR_PTR(), so these
      addresses are unlikely to be mapped.

      perf_counter: Add event overlow handling · 43a21ea8
      Peter Zijlstra 提交于
      Alternative method of mmap() data output handling that provides
      better overflow management and a more reliable data stream.
      
      Unlike the previous method, that didn't have any user->kernel
      feedback and relied on userspace keeping up, this method relies on
      userspace writing its last read position into the control page.
      
      It will ensure new output doesn't overwrite not-yet read events,
      new events for which there is no space left are lost and the
      overflow counter is incremented, providing exact event loss
      numbers.

      Add boundary checks for call-chain events. In case of corrupted

      perf_counter: Make set_perf_counter_pending() declaration common · 9974458e
      Paul Mackerras 提交于
      At present, every architecture that supports perf_counters has to
      declare set_perf_counter_pending() in its arch-specific headers.
      This consolidates the declarations into a single declaration in one
      common place, include/linux/perf_counter.h.  On powerpc, we continue
      to provide a static inline definition of set_perf_counter_pending()
      in the powerpc hw_irq.h.
      
      Also, this removes from the x86 perf_counter.h the unused null
      definitions of {test,clear}_perf_counter_pending.

      perf_counter: Add forward/backward attribute ABI compatibility · 974802ea
      Peter Zijlstra 提交于
      Provide for means of extending the perf_counter_attr in a 'natural' way.
      
      We allow growing the structure by appending fields at the end by specifying
      the full structure size inside it.
      
      When a new kernel sees a smaller (old) structure, it will 0 pad the tail.
      When an old kernel sees a larger (new) structure, it will verify the tail
      consists of 0s, otherwise fail.
      
      If we fail due to a size-mismatch, we return -E2BIG and write the kernel's
      native attribe size back into the provided structure.
      
      Furthermore, add some attribute verification, so that we'll fail counter
      creation when unknown bits are present (PERF_SAMPLE, PERF_FORMAT, or in
      the __reserved fields).
      
      (This ABI detail is introduced while keeping the existing syscall ABI.)

      is_software_counter() was missing the new HW_CACHE category.
      
      ( This could have caused some counter scheduling artifacts
        with mixed sw and hw counters and counter groups. )
