Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 

Pull perf updates from Ingo Molnar:
 "Kernel side changes:

   - Improved kbprobes robustness

   - Intel PEBS support for PT hardware tracing

   - Other Intel PT improvements: high order pages memory footprint
     reduction and various related cleanups

   - Misc cleanups

  The perf tooling side has been very busy in this cycle, with over 300
  commits. This is an incomplete high-level summary of the many
  improvements done by over 30 developers:

   - Lots of updates to the following tools:

      'perf c2c'
      'perf config'
      'perf record'
      'perf report'
      'perf script'
      'perf test'
      'perf top'
      'perf trace'

   - Updates to libperf and libtraceevent, and a consolidation of the
     proliferation of x86 instruction decoder libraries.

   - Vendor event updates for Intel and PowerPC CPUs,

   - Updates to hardware tracing tooling for ARM and Intel CPUs,

   - ... and lots of other changes and cleanups - see the shortlog and
     Git log for details"

* tep_print_event - Write various event information
* @tep: a handle to the trace event parser context
* @s: the trace_seq to write to
* @record: The record to get the event from
* @format: a printf format string. Supported event fileds:
* TEP_PRINT_PID, "%d" - event PID
* TEP_PRINT_CPU, "%d" - event CPU
* TEP_PRINT_COMM, "%s" - event command string
* TEP_PRINT_NAME, "%s" - event name
* TEP_PRINT_LATENCY, "%s" - event latency
* TEP_PRINT_TIME, %d - event time stamp. A divisor and precision
* can be specified as part of this format string:
* "%precision.divisord". Example:
* "%3.1000d" - divide the time by 1000 and print the first
* 3 digits before the dot. Thus, the time stamp
* "123456000" will be printed as "123.456"
* TEP_PRINT_INFO, "%s" - event information. If any width is specified in
* the format string, the event information will be printed
* in raw format.
* Writes the specified event information into @s.

PEBS via Intel PT
=================
Some hardware has the feature to redirect PEBS records to the Intel PT trace.
Recording is selected by using the aux-output config term e.g.
perf record -c 10000 -e '{intel_pt/branch=0/,cycles/aux-output/ppp}' uname
Note that currently, software only supports redirecting at most one PEBS event.
To display PEBS events from the Intel PT trace, use the itrace 'o' option e.g.
perf script --itrace=oe

Record events of type PERF_RECORD_NAMESPACES and display it with the
'cgroup_id' sort key.
--switch-on EVENT_NAME::
Only consider events after this event is found.
E.g.:
Find out where broadcast packets are handled
perf probe -L icmp_rcv
Insert a probe there:
perf probe icmp_rcv:59
Start perf top and ask it to only consider the cycles events when a
broadcast packet arrives This will show a menu with two entries and
will start counting when a broadcast packet arrives:
perf top -e cycles,probe:icmp_rcv --switch-on=probe:icmp_rcv
Alternatively one can ask for --group and then two overhead columns
will appear, the first for cycles and the second for the switch-on event.
perf top --group -e cycles,probe:icmp_rcv --switch-on=probe:icmp_rcv
This may be interesting to measure a workload only after some initialization
phase is over, i.e. insert a perf probe at that point and use the above
examples replacing probe:icmp_rcv with the just-after-init probe.
--switch-off EVENT_NAME::
Stop considering events after this event is found.
--show-on-off-events::
Show the --switch-on/off events too. This has no effect in 'perf top' now
but probably we'll make the default not to show the switch-on/off events
on the --group mode and if there is only one event besides the off/on ones,
go straight to the histogram browser, just like 'perf top' with no events
explicitely specified does.
