Zhouyi Zhou 8e50d384cc perf tools: Fixup mmap event consumption
The tail position of the event buffer should only be modified after
actually use that event.

If not the event buffer could be invalid before use, and segment fault
occurs when invoking perf top -G.

Stephane Eranian 5c5e854bc7 perf tools: Add attr->mmap2 support
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 53a277e5c9 perf tools: Add test for parsing with no sample_id_all bit
Add a test for parsing a non-sample event when there is more than one
selected event but no sample_id_all bit set.

The test fails because of a bug in the evlist logic.  That is fixed in a
separate patch.

Adrian Hunter 314add6b1f perf tools: change machine__findnew_thread() to set thread pid
Add a new parameter for 'pid' to machine__findnew_thread().
Change callers to pass 'pid' when it is known.

Note that callers sometimes want to find the main thread
which has the memory maps.  The main thread has tid == pid
so the usage in that case is:

	machine__findnew_thread(machine, pid, pid)

whereas the usage to find the specific thread is:

	machine__findnew_thread(machine, pid, tid)

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.

Jiri Olsa 66cd3f3a6c perf tests: Fix exclude_guest|exclude_host checking for attr tests
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.

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.
