[PATCH 01/66] perf tools: Fix bug in isupper() and islower()

[Arnaldo Carvalho de Melo]

From: Sukadev Bhattiprolu <sukadev@linux.vnet.ibm.com>

One of the reasons 'perf test' is failing on Power appears to be due to
a bug in isupper().

isupper(c) and islower(c) should be checking 'c' against the mask 0x20.
Instead they are checking sane_ctype[c] which causes isupper() to be
true for lower case letters.

[PATCH 02/66] perf hists: Fix an invalid memory free on he->branch_info

[Arnaldo Carvalho de Melo]

From: Namhyung Kim <namhyung.kim@lge.com>

The branch info was allocated for the whole stack and passed matching
hist entry for each level during processing samples.  Thus when a hist
entry tries to free its branch info like in hists__collapse_insert_entry
it'll face following error.

  *** glibc detected *** perf: munmap_chunk(): invalid pointer: 0x00000000014e9d20 ***
  ======= Backtrace: =========
  /lib64/libc.so.6[0x387d47ae16]
  perf[0x4923bd]
  perf(cmd_report+0xd68)[0x432a08]
  perf[0x41a663]
  perf(main+0x58f)[0x419eaf]
  /lib64/libc.so.6(__libc_start_main+0xf5)[0x387d421735]
  perf[0x419f95]

Fix it by allocating and copying branch info for each new hist entry.

[PATCH 04/66] perf report: Fix alignment of symbol column when -v is given

[Arnaldo Carvalho de Melo]

From: Namhyung Kim <namhyung.kim@lge.com>

When -v option is given, the symbol sort key prints its address also but
it wasn't properly aligned since hists__calc_col_len() misses the
additional part.  Also it missed 2 spaces for 0x prefix when printing.

  $ perf report --stdio -v -s sym

[PATCH 07/66] perf sort: Separate out memory-specific sort keys

[Arnaldo Carvalho de Melo]

From: Namhyung Kim <namhyung.kim@lge.com>

Since they're used only for perf mem, separate out them to a different
dimension so that normal user cannot access them by any chance.

For global/local weights, I'm not entirely sure to place them into the
memory dimension.  But it's the only user at this time.

[PATCH 11/66] perf sort: Cleanup sort__has_sym setting

[Arnaldo Carvalho de Melo]

From: Namhyung Kim <namhyung.kim@lge.com>

The sort__has_sym variable is set only if a symbol-related sort key was
added.  Since branch stack and memory sort dimensions are separated, it
doesn't need to be checked from common dimension.

[PATCH 15/66] perf tests: Fix compile errors in bp_signal files

[Arnaldo Carvalho de Melo]

From: Sukadev Bhattiprolu <sukadev@linux.vnet.ibm.com>

When building on powerpc,  we get compile errors in bp_signal.c and
bp_signal_overflow.c due to __u64 and '%llx'.

Powerpc, needs __SANE_USERSPACE_TYPES__ to be defined so we pick up
<asm-generic/int-ll64.h> and define __u64 as unsigned long long.

[PATCH 17/66] perf record: handle death by SIGTERM

[Arnaldo Carvalho de Melo]

From: David Ahern <dsahern@gmail.com>

Perf data files cannot be processed until the header is updated which is
done via an on_exit handler.

If perf is killed due to a SIGTERM it does not run the on_exit hooks
leaving the perf.data file in a random state which perf-report will
happily spin on trying to read.

As noted by Mike an easy reproducer is:

perf record -a -g & sleep 1; killall perf

Fix by catching SIGTERM like it does SIGINT.

Also need to remove the kill which was added via commit f7b7c26e.

[PATCH 18/66] perf top: Fix -E option behavior

[Arnaldo Carvalho de Melo]

From: Namhyung Kim <namhyung.kim@lge.com>

The -E/--entries option controls how many lines to be printed on stdio
output but it doesn't work as it should be:

If -E option is specified, print that many lines regardless of current
window size, if not automatically adjust number of lines printed to fit
into the window size.

[PATCH 20/66] perf top: Get rid of *_threaded() functions

[Arnaldo Carvalho de Melo]

From: Namhyung Kim <namhyung.kim@lge.com>

Those _threaded() functions are needed to make hist tree handling
thread-safe, but AFAICS the only thing it does is forcing it to use
the intermediate 'collapsed' tree.

This can be acheived by setting sort__need_collapse to 1 in cmd_top() so
no need to keep those _threaded() variants.

[PATCH 22/66] perf report: Don't bother locking when adding hist entries

[Arnaldo Carvalho de Melo]

From: Namhyung Kim <namhyung.kim@lge.com>

The 'perf report'command is single-threaded, so no need to grab a lock.

Although the fast path of pthread_mutex_[un]lock() is very fast, there's
a ~3% gain by eliminating it when we have huge sample data.

  $ perf record -a -F 100000 -o perf.data.bench -- perf bench sched all
  $ perf record -e cycles:upp -o perf.data.before -- \
  > perf report -i perf.data.bench --stdio > /dev/null
  ... apply this patch ...
  $ perf record -e cycles:upp -o perf.data.after -- \
  > perf report -i perf.data.bench --stdio > /dev/null
  $ perf diff perf.data.{before,after} | grep pthread

[PATCH 23/66] perf report: Add --percent-limit option

[Arnaldo Carvalho de Melo]

From: Namhyung Kim <namhyung.kim@lge.com>

The --percent-limit option is for not showing small overhead entries in
the output.  Maybe we want to set a certain default value like 0.1.

[PATCH 27/66] perf hists: Rename hist_entry__add_pair arguments

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@redhat.com>

The current logic is to attach pair to the leader hist_entry.

Arguments of hist_entry__add_pair function were placed the other way
round.. driving me crazy.

I.e. list_add_tail expects (new_node, head).

[PATCH 33/66] perf tools: Add automated make test suite

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@redhat.com>

Adding automated test for testing the build process.

To run it you need to be in perf directory or specify one with PERF
variable. It's also possible to specify optional Makefile to test via MK
variable.

Whole suite is executed twice, the second time with O=/tmp/xxx option
added.

To run the whole suite:
  $ make -f tests/make
  - make_pure: cd . && make -f Makefile
    test: test -x ./perf
  - make_clean_all: cd . && make -f Makefile clean all
    test: test -x ./perf
  - make_python_perf_so: cd . && make -f Makefile python/perf.so
    test: test -f ./python/perf.so
  - make_debug: cd . && make -f Makefile DEBUG=1
    test: test -x ./perf
  - make_no_libperl: cd . && make -f Makefile NO_LIBPERL=1
    test: test -x ./perf

You see command line for 'make_pure' test right away, and the output is
stored into 'make_pure' file.

To run simple test:
  $ make -f tests/make make_debug
  - make_debug: cd . && make -f Makefile DEBUG=1
    test: test -x ./perf

At this moment tests checks for successfull build and for existence of
several built files. Additional after-build checks could be added.

[PATCH 51/66] perf tests: Fix exclude_guest|exclude_host checking for attr tests

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@redhat.com>

We have a one of the event open fallback case in __perf_evsel__open
where we zero exclude_guest|exclude_host fields.

This means there's no way for attr tests to find out what's the right
value for those fields, so we need to check for both 0 and 1. Luckily we
still have other event parsing tests for those fields.

[PATCH 55/66] perf: Power7: Make CPI stack events available in sysfs

[Arnaldo Carvalho de Melo]

From: Sukadev Bhattiprolu <sukadev@linux.vnet.ibm.com>

A set of Power7 events are often used for Cycles Per Instruction (CPI) stack
analysis. Make these events available in sysfs (/sys/devices/cpu/events/) so
they can be identified using their symbolic names:

	perf stat -e 'cpu/PM_CMPLU_STALL_DCACHE_MISS/' /bin/ls

[PATCH 57/66] perf: Expand definition of sysfs format attribute

[Arnaldo Carvalho de Melo]

From: Michael Ellerman <michael@ellerman.id.au>

Make it explicit that the format attributes may define overlapping bit
ranges. Unfortunately this was left unspecified originally, and all the
examples show non-overlapping ranges. I don't believe this is an ABI
change, as we are defining something that was previously undefined, but
others may disagree.

The POWER8 PMU would like to define overlapping ranges, as bit ranges in
the event code have different meanings for certain events. It will also
allow us to define an overarching "event" field, that encompasses all
others.

As far as I can see perf is comfortable with this change, however I am
not sure if there are any other users of the interface.

[PATCH 58/66] perf evlist: Reset SIGTERM handler in workload child process

[Arnaldo Carvalho de Melo]

From: David Ahern <dsahern@gmail.com>

Jiri reported hanging perf tests on latest acme's perf/core and bisected
it to 87f303a9f:

[jolsa@krava2 perf]$ cat /proc/sys/kernel/perf_event_paranoid
1
[jolsa@krava2 perf]$ ./perf record -C 0 kill
Error:
You may not have permission to collect %sstats.
Consider tweaking /proc/sys/kernel/perf_event_paranoid:
 -1 - Not paranoid at all
  0 - Disallow raw tracepoint access for unpriv
  1 - Disallow cpu events for unpriv
  2 - Disallow kernel profiling for unpriv
