Merge tag 'perf-core-for-mingo-4.17-20180216' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

- Fix wrong jump arrow in systems with branch records with cycles,
  i.e. Intel's >= Skylake (Jin Yao)

- Fix 'perf record --per-thread' problem introduced when
  implementing 'perf stat --per-thread (Jin Yao)

- Use arch__compare_symbol_names() to fix 'perf test vmlinux',
  that was using strcmp(symbol names) while the dso routines
  doing symbol lookups used the arch overridable one, making
  this test fail in architectures that overrided that function
  with something other than strcmp() (Jiri Olsa)

- Add 'perf script --show-round-event' to display
  PERF_RECORD_FINISHED_ROUND entries (Jiri Olsa)

- Fix dwarf unwind for stripped binaries in 'perf test' (Jiri Olsa)

- Use ordered_events for 'perf report --tasks', otherwise we may get
  artifacts when PERF_RECORD_FORK gets processed before PERF_RECORD_COMM
  (when they got recorded in different CPUs) (Jiri Olsa)

- Add support to display group output for non group events, i.e.
  now when one uses 'perf report --group' on a perf.data file
  recorded without explicitly grouping events with {} (e.g.
  "perf record -e '{cycles,instructions}'" get the same output
  that would produce, i.e. see all those non-grouped events in
  multiple columns, at the same time (Jiri Olsa)

- Skip non-address kallsyms entries, e.g. '(null)' for !root (Jiri Olsa)

- Kernel maps fixes wrt perf.data(report) versus live system (top)
  (Jiri Olsa)

- Fix memory corruption when using 'perf record -j call -g -a <application>'
  followed by 'perf report --branch-history' (Jiri Olsa)

- ARM CoreSight fixes (Mathieu Poirier)

- Add inject capability for CoreSight Traces (Robert Waker)

- Update documentation for use of 'perf' + ARM CoreSight (Robert Walker)

- Man pages fixes (Sangwon Hong, Jaecheol Shin)

- Fix some 'perf test' cases on s/390 and x86_64 (some backtraces
  changed with a glibc update) (Thomas Richter)

- Add detailed CPUID info in the 'perf.data' headers for s/390 to
  then use it in 'perf annotate' (Thomas Richter)

- Add '--interval-count N' to 'perf stat', to use with -I, i.e.
  'perf stat -I 1000 --interval-count 2' will show stats every
   1000ms, two times (yuzhoujian)

- Add 'perf stat --timeout Nms', that will run for that many
  milliseconds and then stop, printing the counters (yuzhoujian)

- Fix description for 'perf report --mem-modex (Andi Kleen)

- Use a wildcard to remove the vfs_getname probe in the
  'perf test' shell based test cases (Arnaldo Carvalho de Melo)

+Using perf tools
+----------------
+
+perf can be used to record and analyze trace of programs.
+
+Execution can be recorded using 'perf record' with the cs_etm event,
+specifying the name of the sink to record to, e.g:
+
+    perf record -e cs_etm/@20070000.etr/u --per-thread
+
+The 'perf report' and 'perf script' commands can be used to analyze execution,
+synthesizing instruction and branch events from the instruction trace.
+'perf inject' can be used to replace the trace data with the synthesized events.
+The --itrace option controls the type and frequency of synthesized events
+(see perf documentation).
+
+Note that only 64-bit programs are currently supported - further work is
+required to support instruction decode of 32-bit Arm programs.
+
+
+Generating coverage files for Feedback Directed Optimization: AutoFDO
+---------------------------------------------------------------------
+
+'perf inject' accepts the --itrace option in which case tracing data is
+removed and replaced with the synthesized events. e.g.
+
+        perf inject --itrace --strip -i perf.data -o perf.data.new
+
+Below is an example of using ARM ETM for autoFDO.  It requires autofdo
+(https://github.com/google/autofdo) and gcc version 5.  The bubble
+sort example is from the AutoFDO tutorial (https://gcc.gnu.org/wiki/AutoFDO/Tutorial).
+
+        $ gcc-5 -O3 sort.c -o sort

+        Bubble sorting array of 30000 elements
+        5910 ms
+
+        $ perf record -e cs_etm/@20070000.etr/u --per-thread taskset -c 2 ./sort
+        Bubble sorting array of 30000 elements
+        12543 ms

+        [ perf record: Captured and wrote 69.640 MB perf.data ]
