According to Documentation/Changes, the kernel should be buildable with
GNU make 3.80+. tools/perf/config/utilities.mak contains the "$(or"
construct, which requires make 3.81. This causes "make" to fail on
systems with GNU make 3.80.
Replace "$(or" with an equivalent "$(if" expression, to restore backward
compatibility. Also fix an issue where _get_attempt was called with only
one argument. This prevented the error message from printing the name of
the variable that can be used to fix the problem.

The ui__error/warning functions use gtk infobar or statusbar and pr_*
functions use statusbar too. But after perf gtk context created but
those infobar and/or statusbar not yet set up, calling one of those
functions will get a segment fault.
Although current code has no problem, move these setting as early as
possible so that it can prevent the segfault from future change.

Test can currently return one of 3 states: ok, fail, skip.
The ok and fail states are self-explanatory. The skip state means that
some of the conditions for running the test was not met, making it
impossible to even run the test. For instance, if the hardware doesn't
support the 'precise' level required by a test, it will be skipped.

The 3786063 commit:
perf kvm: Rename perf_kvm to perf_kvm_stat
Moved the file_name from inside a local struct var that initialized some
of its members, thus zero initializing the not explicitely initialized
variables, one of which was 'file_name', to a standalone local variable,
but forgot to initialize it explicitely to NULL, so it then got some
undefined value, causing a segfault in strdup when it wasn't, by luck,
zero.
Fix it by explicitely initializing it to NULL.

Current perf test code tries to execute python version 2 in order to
test attributes on perf_event_open syscall. However it's not default
python version anymore a system can have python v3 only or v2 with a
different name (e.g. python2). So if there's no such python interpreter
with the name 'python', the test would fail like this (yes, it's
happened on my new archlinux laptop :).
13: struct perf_event_attr setup :sh: python: command not found
FAILED!
As we can pass name of the python interpreter on make, use it for
the attr test also.

Adding event parsing test for '*:*' tracepoints. Checking the count
matches all the tracepoints available plus current standard tracepoint
perf_event_attr check.
This test exposes warnings from traceevent lib about not being able to
parse some tracepoints' format data. Exposing these messages in the
automated test suite will probably speed up the fix ;-)

Adding support for wildcards '*?" in the tracepoint system part.
It's now possible to open all available tracepoints like:
# perf stat -e '*:*' ls
You might need to increase limit for open files via ulimit.
If ftrace events tracepoints are configured in, the record command fails
on above event selection because of them.
The stat command disables counters that fails to open, the record
command fails completely. We probably want to be smarter here.

The test_attr infrastructure hooks on the sys_perf_event_open call,
checking if a variable is set and if so calling a function to intercept
calls and do the checking.
But both the variable and the function aren't on objects that are
linked on the python binding, breaking it:
# perf test -v 15
15: Try 'use perf' in python, checking link problems :
--- start ---
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: /home/acme/git/build/perf//python/perf.so: undefined symbol: test_attr__enabled
---- end ----
Try 'use perf' in python, checking link problems: FAILED!
#
Fix it by moving the variable to one of the linked object files and
providing a stub for the function in the python.o object, that is only
linked in the python binding.
Now 'perf test' is happy again:
# perf test 15
15: Try 'use perf' in python, checking link problems : Ok

attr tests
Now we'll see the command being run and if it fails, the fields that had
unexpected values and the expected values, example testing a problem in the
next patch:
# perf test -v 13
13: struct perf_event_attr setup :
--- start ---
SNIP
running 'PERF_TEST_ATTR=/tmp/tmpDNIE6M /home/acme/bin/perf record -o /tmp/tmpDNIE6M/perf.data --group -e cycles,instructions kill >/dev/null 2>&1' ret 0
running 'PERF_TEST_ATTR=/tmp/tmpV5lKro /home/acme/bin/perf stat -o /tmp/tmpV5lKro/perf.data -dd kill >/dev/null 2>&1' ret 1
expected config=3, got 65540
expected exclude_guest=1, got 0
FAILED '/home/acme/libexec/perf-core/tests/attr/test-stat-detailed-2' - match failure
---- end ----
struct perf_event_attr setup: FAILED!
#
While in the past we would see at the '-v' level many more messages for the
fields that matched, something we may want to see only in the '-vv' log level.
Keeping the 'running' messages so that we can see the tools tests that
succeeded so that we can compare it to the one that failed, helping pinpointing
the command line switch combo that leads to the problem.

As they are used from diff and event group report, add a test case to
verify their behaviors.
In this test I made a fake machine and two evsel. Each evsel got 10
samples (so hist entries) - 5 are common and the rests are not. So
after hists__match() both of them will have 5 entries with pair set.
And the second evsel has a collapsed entry so that the total number is 9
- I made it in order to simulate more realistic case. Thus after
hists__link the first entry will have 14 entries - 5 are common (w/
pair), 5 are unmatch (w/o pair) and 4 are dummy (w/ pair). And the
second entry will have 9 entries all have its pair.

For matching and/or linking hist entries, they need to be sorted by
given sort keys. However current hists__match/link did this on the
output trees, so that the entries in the output tree need to be resort
before doing it.
This looks not so good since we have trees for collecting or collapsing
entries before passing them to an output tree and they're already sorted
by the given sort keys. Since we don't need to print anything at the
time of matching/linking, we can use these internal trees directly
instead of bothering with double resort on the output tree.
Its only user - at the time of this writing - perf diff can be easily
converted to use the internal tree and can save some lines too by
getting rid of unnecessary resorting codes.

When comparing entries for collapsing put the given entry first, and
then the iterated entry. This is not the case of hist_entry__cmp() when
called if given sort keys don't require collapsing. So change the order
for the sake of consistency. It will be required for matching and/or
linking multiple hist entries.

. No need to do feature checks when doing a 'make tags'
. Fix some 'perf test' errors and make them use the tracepoint evsel constructor.
. perf top now shares more of the evsel config/creation routines with 'record',
paving the way for further integration like 'top' snapshots, etc.
. perf top now supports DWARF callchains.
. perf evlist decodes sample_type and read_format, helping diagnose problems.
. Fix mmap limitations on 32-bit, fix from David Miller.

It's silly to create directories without execute permission, or to
give permissions to 'other' but not the group-owner.
Write the permissions in octal and 'ls -l' format since these are much
easier to read than the named macros.

Initial patch by Ben Hutchings <[email protected]>
We will install this in /usr, so it must use /var/lib for its state.
Only programs installed under /opt should use /var/opt.

Basically remove unneeded code. Since that 'continue' is at the end
of the for() there's no need for it.

The CONFIG_EXPERIMENTAL config item has not carried much meaning for a
while now and is almost always enabled by default. As agreed during the
Linux kernel summit, remove it from any "depends on" lines in Kconfigs.

The error handling in cgroup_event_listener.c did not correctly deal
with either an error opening either <control_file> or
cgroup.event_control. Due to an uninitialized variable the program
exit code was undefined if either of these opens failed.
This patch simplifies and corrects cgroup_event_listener.c error
handling by:
1. using err*() rather than printf(),exit()
2. depending on process exit to close open files
With this patch failures always return non-zero error.

Move the cgroup_event_listener.c tool from Documentation into the new
tools/cgroup directory.
This change involves wiring cgroup_event_listener.c into the tools/
make system so that is can be built with:
$ make tools/cgroup
