Alexander Yarygin 615b8f99f7 perf tests: Add numeric identifier to evlist_test
In tests/parse-events.c test cases are declared in evlist_test[]
arrays. Elements of arrays are initialized in following pattern:
	[i] = {
 		.name  = ...,
 		.check = ...,
 	},

When perf-test is running with '-v' option, 'i' variable will be
printed for every existing test.

However, we can't add any arch specific tests inside #ifdefs, because it
will create collision between the element number inside #ifdef and the
next one outside.

This patch adds 'id' field in evlist_test, uses it as a test
identifier and removes explicit numbering of array elements. This helps
to number tests with gaps.

Jiri Olsa 4e85edfc3f perf tests: Add thread maps lookup automated tests
Adding automated test for memory maps lookup within multiple machines
threads.

The test creates 4 threads and separated memory maps. It checks that we
could use thread__find_addr_map function with thread object based on TID
to find memory maps.

Jiri Olsa aa16b81fe9 perf tests x86: Add dwarf unwind test
Adding dwarf unwind test, that setups live machine data over the perf
test thread and does the remote unwind.

At this moment this test fails due to bug in the max_stack processing in
unwind__get_entries function.  This is fixed in following patch.

Need to use -fno-optimize-sibling-calls for test compilation, otherwise
'krava_*' function calls are optimized into jumps and ommited from the
stack unwind.

So far it's enabled only for x86.

Arnaldo Carvalho de Melo 4887805384 perf tools: Add test for building detached source tarballs
Test one of the main kernel Makefile targets to generate a perf sources
tarball suitable for build outside the full kernel sources.

This is to test that the tools/perf/MANIFEST file lists all the files
needed to be in such tarball, which sometimes gets broken when we move
files around, like when we made some files that were in tools/perf/
available to other tools/ codebases by moving it to tools/include/, etc.

Now everytime we use 'make -C tools/perf -f tests/make' this test will
be performed, helping detect such problems earlier in the devel cycle.

Factoring make install tests to check for multiple files. Adding default

Putting the 'test' line into the log file instead to the screen as it

If the tests fails to find a file, following message is displayed:

$ make -f tests/make make_install_bin

Borislav Petkov 553873e1df tools/: Convert to new topic libraries
Move debugfs.* to api/fs/. We have a common tools/lib/api/ place where
the Makefile lives and then we place the headers in subdirs.

For example, all the fs-related stuff goes to tools/lib/api/fs/ from
which we get libapikfs.a (acme got almost the naming he wanted :-)) and
we link it into the tools which need it - in this case perf and
tools/vm/page-types.

acme:

"Looking at the implementation, I think some tools can even link
directly to the .o files, avoiding the .a file altogether.

But that is just an optimization/finer granularity tools/lib/
cherrypicking that toolers can make use of."

Fixup documentation cleaning target while at it.

Consequently add an option to select per-thread mmaps to support the old

Note that per-thread can be used with a workload-only (i.e. none of -p,

[root@ssdandy ~]# cat /proc/sys/kernel/perf_event_max_sample_rate
7000

Reducing it to 500 Hz should be good enough for this test and also
shouldn't affect what it is testing.

But warn the user if it fails, informing the knob and the freq tried.

Arnaldo Carvalho de Melo ef503831d8 perf evsel: Remove idx parm from constructor
Most uses of the evsel constructor are followed by a call to
perf_evlist__add with an idex of evlist->nr_entries, so make rename
the current constructor to perf_evsel__new_idx and remove the need
for passing the constructor for the common case.

We still need the new_idx variant because the way groups are handled,
with evsel->nr_members holding the number of entries in an evlist,
partitioning the evlist into sublists inside a single linked list.

This asks for a clarifying refactoring, but for now simplify the non
parser cases, so that tool writers don't have to bother with evsel idx
setting.

Arnaldo Carvalho de Melo 46d525eae2 perf test: Update command line callchain attribute tests
The "struct perf_event_attr setup" entry in 'perf test' is in fact a
series of tests that will exec the tools, passing different sets of
command line arguments to then intercept the sys_perf_event_open
syscall, in user space, to check that the perf_event_attr->sample_type
and other feature request bits are setup as expected.

We recently restored the callchain requesting command line argument, -g,
to not require a parameter ("dwarf" or "fp"), instead using a default
("fp" for now) and making the long option variant, --call-chain, be the
one to be used when a different callchain collection method is
preferred.

The "struct perf_event_attr setup" test failed because we forgot to
update the tests involving callchains, not switching from, '-g dwarf' to
'--call-chain dwarf', making 'perf test' detect it:

  [root@sandy ~]# perf test -v 13
  13: struct perf_event_attr setup                           :

  FAILED '/home/acme/libexec/perf-core/tests/attr/test-record-graph-dwarf' - match failure
  ---- end ----
  struct perf_event_attr setup: FAILED!
  [root@sandy ~]#

Fix all of them now to use --call-chain when explicitely specifying a
method.

There is still work to do, as '-g fp', for instance, passed without
problems.

In that case 'perf test' saw no problems as the intercepted syscall got
the bits as expected, i.e. the default is 'fp', but the fact that 'fp'
may be an existing program and the specified workload would then be
passed as a parameter to it is an usability problem that needs fixing.

Next merge window tho.

This patch adds support for the new PERF_RECORD_MMAP2 record type
exposed by the kernel. This is an extended PERF_RECORD_MMAP record.

It adds for each file-backed mapping the device major, minor number and
the inode number and generation.

This triplet uniquely identifies the source of a file-backed mapping. It
can be used to detect identical virtual mappings between processes, for
instance.

The patch will prefer MMAP2 over MMAP.

Adrian Hunter 5b7ba82a75 perf symbols: Load kernel maps before using
In order to use kernel maps to read object code, those maps must be
adjusted to map to the dso file offset.  Because lazy-initialization is
used, that is not done until symbols are loaded.  However the maps are
first used by thread__find_addr_map() before symbols are loaded.  So
this patch changes thread__find_addr() to "load" kernel maps before
using them.

We have a one of the event open fallback case in __perf_evsel__open

This means there's no way for attr tests to find out what's the right

still have other event parsing tests for those fields.

Jiri Olsa 095ae69b89 perf tools: Add automated make test suite
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.

Andi Kleen 05484298cb perf tools: Add support for weight v7 (modified)
perf record has a new option -W that enables weightened sampling.

Add sorting support in top/report for the average weight per sample and the
total weight sum. This allows to both compare relative cost per event
and the total cost over the measurement period.

Add the necessary glue to perf report, record and the library.

v2: Merge with new hist refactoring.
v3: Fix manpage. Remove value check.
Rename global_weight to weight and weight to local_weight.
v4: Readd sort keys to manpage
v5: Move weight to end
v6: Move weight to template
v7: Rename weight key.

Original patch from Andi modified by Stephane Eranian <eranian@google.com>
to include ONLY the weight supporting code and apply to pristine 3.8.0-rc4.

Jiri Olsa 5a6bef47b4 perf tests: Test breakpoint overflow signal handler
Adding automated test for breakpoint event signal handler checking if
it's executed properly.

The test is related to the proper handling of the RF EFLAGS bit on
x86_64, but it's generic for all archs.

First we check the signal handler is properly called and that the
following debug exception return to user space wouldn't trigger
recursive breakpoint.

This is related to x86_64 RF EFLAGS bit being managed in a wrong way.

Second we check that we can set breakpoint in signal handler, which is
not possible on x86_64 if the signal handler is executed with RF EFLAG
set.

This test is inpired by overflow tests done by Vince Weaver.

Namhyung Kim 119fa3c922 perf evlist: Do not pass struct record_opts to perf_evlist__prepare_workload()
Since it's only used for checking ->pipe_output, we can pass the result
directly.

Now the perf_evlist__prepare_workload() don't have a dependency of
struct perf_record_opts, it can be called from other places like perf
stat.
