Libtraceevent APIs for printing various trace events information are
complicated, there are complex extra parameters. To control the way
event information is printed, the user should call a set of functions in
a specific sequence.

These APIs are reimplemented to provide a more simple interface for
printing event information.

Removed APIs:

 	tep_print_event_task()
	tep_print_event_time()
	tep_print_event_data()
	tep_event_info()
	tep_is_latency_format()
	tep_set_latency_format()
	tep_data_latency_format()
	tep_set_print_raw()

A new API for printing event information is introduced:
   void tep_print_event(struct tep_handle *tep, struct trace_seq *s,
		        struct tep_record *record, const char *fmt, ...);
where "fmt" is a printf-like format string, followed by the event
fields to be printed. Supported fields:
 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.
 TEP_PRINT_INFO_RAW, "%s" - event information, in raw format.

Example:
  tep_print_event(tep, s, record, "%16s-%-5d [%03d] %s %6.1000d %s %s",
		  TEP_PRINT_COMM, TEP_PRINT_PID, TEP_PRINT_CPU,
		  TEP_PRINT_LATENCY, TEP_PRINT_TIME, TEP_PRINT_NAME, TEP_PRINT_INFO);

Merge tag 'perf-core-for-mingo-5.4-20190829' 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:

perf top:

  Namhyung Kim:

  - Decay all events in the evlist, we were decaying just the first event
    in a group.

  - Fix linking of histograms in different evsels in a event group with more
    than two events.

  With the two fixes above a command line such as:

    # perf top -e '{cycles,instructions,cache-misses,cache-references}

    Should work as expected, with four columns and with all of them being
    decayed over time, i.e. less weight is given for older samples.

perf record:

  Arnaldo Carvalho de Melo:

  - Fix collection of build-ids when using setns() to get into namespaces,
    which had been broken with the introduction of the extra thread to
    react to PERF_RECORD_BPF_EVENT, i.e. to collect extra info for BPF
    programs. We need to unshare(CLONE_FS) in that thread so that the
    main one can do the setns(CLONE_NEWNS) when collectingthe build-ids.
    Without that symbol resolution gets more difficult and potentially
    misresolves symbols.

core:

  Igor Lubashev:

  - Further alignment in permission checking via capabilities to how the
    kernel checks what tooling tries to do.

PowerPC:

  Naveen N. Rao:

  - Sync powerpc syscall.tbl, so that 'perf trace' gets the definitions
    for recent syscalls.

libperf:

  Jiri Olsa:

  - Move the rest of the PERF_RECORD_ metadata struct definitions so that
    we can use 'union perf_event'.

libtraceevent:

While reading a trace data file that had 100,000s of tasks, the process
took an extremely long time. I profiled it down to add_new_comm(), which
was doing a qsort() call on an array that was pretty much already sorted
(all but the last element. qsort() isn't very efficient when dealing
with mostly sorted arrays, and this definitely showed its issues.

When adding a new task to the task list, instead of using qsort(), do
another bsearch() with a function that will find the element before
where the new task will be inserted in. Then simply shift the rest of
the array, and insert the task where it belongs.

If the re-allocation of tep->cmdlines succeeds, then the previous
allocation of tep->cmdlines will be freed. If we later fail in
add_new_comm(), we must not free cmdlines, and also should assign
tep->cmdlines to the new allocation. Otherwise when freeing tep, the
tep->cmdlines will be pointing to garbage.

When we started using a thread to catch the PERF_RECORD_BPF_EVENT meta
data events to then ask the kernel for further info (BTF, etc) for BPF
programs shortly after they get loaded, we forgot to use
unshare(CLONE_FS) as was done in:

  868a8329 ("perf top: Support lookup of symbols in other mount namespaces.")

Do it so that we can enter the namespaces to read the build-ids at the
end of a 'perf record' session for the DSOs that had hits.

Before:

Starting a 'stress-ng --cpus 8' inside a container and then, outside the
container running:

  # perf record -a --namespaces sleep 5
  # perf buildid-list | grep stress-ng
  #

We would end up with a 'perf.data' file that had no entry in its
build-id table for the /usr/bin/stress-ng binary inside the container
that got tons of PERF_RECORD_SAMPLEs.

After:

  # perf buildid-list | grep stress-ng
  f2ed02c68341183a124b9b0f6e2e6c493c465b29 /usr/bin/stress-ng
  #

Then its just a matter of making sure that that binary debuginfo package
gets available in a place that 'perf report' will look at build-id keyed
ELF files, which, in my case, on a f30 notebook, was a matter of
installing the debuginfo file for the distro used in the container,
fedora 31:

  # rpm -ivh http://fedora.c3sl.ufpr.br/linux/development/31/Everything/x86_64/debug/tree/Packages/s/stress-ng-debuginfo-0.07.29-10.fc31.x86_64.rpm

Then, because perf currently looks for those debuginfo files (richer ELF
symtab) inside that namespace (look at the setns calls):

  openat(AT_FDCWD, "/proc/self/ns/mnt", O_RDONLY) = 137
  openat(AT_FDCWD, "/proc/13169/ns/mnt", O_RDONLY) = 139

To only then go back to the "host" namespace to look just in the users's
~/.debug cache:

  setns(137, CLONE_NEWNS)                 = 0
  chdir("/root")                          = 0

It continues to fail to resolve symbols:

  # perf report | grep stress-ng | head -5
     9.50%  stress-ng-cpu    stress-ng    [.] 0x0000000000021ac1

To overcome that we use:

  Adding f2ed02c68341183a124b9b0f6e2e6c493c465b29 /usr/lib/debug/usr/bin/stress-ng-0.07.29-10.fc31.x86_64.debug: Ok

  #

Now it finally works:

     3.55%  stress-ng-cpu    stress-ng    [.] queens_try
  #

I'll make sure that it looks for the build-id keyed files in both the
"host" namespace (the namespace the user running 'perf record' was a the
time of the recording) and in the container namespace, as it shouldn't
matter where a content based key lookup finds the ELF file to use in
resolving symbols, etc.
