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)

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.

- make_pure: cd . && make -f Makefile
test: test -x ./perf
- make_clean_all: cd . && make -f Makefile clean all
test: test -x ./perf

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.

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.

We print several '__u64' quantities using '%llu'. On powerpc, we by
default include '<asm-generic/int-l64.h> which results in __u64 being an
unsigned long. This causes compile warnings which are treated as errors
due to '-Werror'.
By defining __SANE_USERSPACE_TYPES__ we include <asm-generic/int-ll64.h>
and define __u64 as unsigned long long.

2: detect open syscall event : Ok
3: detect open syscall event on all cpus : Ok
4: read samples using the mmap interface : Ok

Warning: bad op token {
Warning: bad op token {
Warning: bad op token {
Warning: bad op token {
Warning: function is_writable_pte not defined

So now we can use -s/--skip while the problematic tests are being fixed,
allowing us to test all the other entries:

1: vmlinux symtab matches kallsyms : Ok
2: detect open syscall event : Ok
3: detect open syscall event on all cpus : Ok
4: read samples using the mmap interface : Ok
5: parse events tests : Skip (user override)
6: x86 rdpmc test : Ok
7: Validate PERF_RECORD_* events & perf_sample fields : Ok
8: Test perf pmu format parsing : Ok
9: Test dso data interface : Ok
10: roundtrip evsel->name check : Ok

12: Generate and check syscalls:sys_enter_open event fields: Ok

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.

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

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.

When mmaping multiple events we need to find the right evsel that
matches an event in the ring buffer.
For that we need to set the PERF_FORMAT_ID bit in
perf_event_attr.read_format so that when we read the event fds we get
that id to then hash it and be able later to use perf_evlist__id2evsel
to find the right evsel.
We also need to set the PERF_SAMPLE_ID bit in
perf_event_attr.sample_type to ask for that id to be stashed in each
sample, so that we can demux it.
So add a perf_evsel__set_sample_id() method to do those two things in
one operation.

perf_evsel__parse_sample, but we were failing to update it after
perf_evsel__init(), i.e. when we decide, after creating an evsel, that
we want some extra field bit set.

Convert perf_evsel__is_group_member to perf_evsel__is_group_leader.
This is because the most usecases are using negative form to check
whether the given evsel is a leader or not and it's IMHO somewhat
ambiguous - leader also *is* a member of the group.

Currently the record command sets all events initially as disabled.
There's non conditional perf_evlist__enable call, that enables all
events before we exec tracee program. That actually screws whole
enable_on_exec logic, because the event is enabled before the traced
program got executed.
What we actually want is:
1) For any type of traced program:
- all independent events and group leaders are disabled
- all group members are enabled
Group members are ruled by group leaders. They need to
be enabled, because the group scheduling relies on that.
2) For traced programs executed by perf:
- all independent events and group leaders have
enable_on_exec set
- we don't specifically enable or disable any event during
the record command
Independent events and group leaders are initially disabled
and get enabled by exec. Group members are ruled by group
leaders as stated in 1).
3) For traced programs attached by perf (pid/tid):
- we specifically enable or disable all events during
the record command
When attaching events to already running traced we
enable/disable events specifically, as there's no
initial traced exec call.
Fixing appropriate perf_event_attr test case to cover this change.

Fixing events attributes for groups defined via '{}'.
Currently 'enable_on_exec' attribute in record command and both
'disabled ' and 'enable_on_exec' attributes in stat command are set
based on the 'group' option. This eliminates proper setup for '{}'
defined groups as they don't set 'group' option.
Making above attributes values based on the 'evsel->leader' as this is
common to both group definition.
Moving perf_evlist__set_leader call within builtin-record ahead
perf_evlist__config_attrs call, because the latter needs possible group
leader links in place.

This problem is introduced in 3e7c439a. CPU_ALLOC and related macros are
