Subject: perf tools: Add x86 RDPMC, RDTSC test

Implement a simple test for the self-monitoring data from the
perf mmap data area control page:

 6: x86 rdpmc test:

             0:           6053
             1:          60053
             2:         600059
             3:        6000059
             4:       60000075
             5:      600000247
    Ok

The counts are expected to increase monotonically - these
are recovered via RDPMC, without calling into the kernel.

It might be nice to add logic to automagically turn these numbers into OK/FAIL.

Subject: perf tools: Introduce per user view

The new --uid command line option will show only the tasks for a given
user, using the proc interface to figure out the existing tasks.

Kernel work is needed to close races at startup, but this should already
be useful in many use cases.

Subject: perf bench: Make "default" memcpy() selection actually use glibc's
 implementation

Since arch/x86/lib/memcpy_64.S implements not only __memcpy, but also
memcpy, without further precautions this function will get chose by the
static linker for resolving all references, and hence the "default"
measurement didn't really measure anything else than the
"x86-64-unrolled" one.

Fix this by renaming (through the pre-processor) the conflicting symbol.

On my Westmere system, the glibc variant turns out to require about 4%
less instructions, but 15% more cycles for the default 1Mb block size
measured.

Subject: perf bench: Also allow measuring alternative memcpy implementations

Intended to be able to support the current selection of the preferred
memcpy() implementation, this patch adds the ability to also measure the
two alternative implementations, again by way of using some
pre-processsor replacement.

While on my Westmere system this proves that the movsb based variant is
worse than the movsq based one (since the ERMS feature isn't there), it
also shows that here for the default as well as small sizes the unrolled
variant outperforms the movsq one.

Subject: perf bench: Allow passing an iteration count to "bench mem
 mem{cpy,set}"

"perf stat ... perf bench mem mem..." is pretty meaningless when using
small block sizes (as the overhead of the invocation of each test run
basically hides the actual test result in the noise). Repeating the
actually interesting function's invocation a number of times allows the
results to become meaningful.

Subject: perf tools: Fix broken build by defining _GNU_SOURCE in Makefile

When building on my Debian/mips system, util/util.c fails to build
because commit 1aed2671738785e8f5aea663a6fda91aa7ef59b5 (perf kvm: Do
guest-only counting by default) indirectly includes stdio.h before the
feature selection in util.h is done.  This prevents _GNU_SOURCE in
util.h from enabling the declaration of getline(), from now second
inclusion of stdio.h, and the build is broken.

There is another breakage in util/evsel.c caused by include ordering,
but I didn't fully track down the commit that caused it.

The root cause of all this is an inconsistent definition of _GNU_SOURCE,
so I move the definition into the Makefile so that it is passed to all
invocations of the compiler and used uniformly for all system header
files.  All other #define and #undef of _GNU_SOURCE are removed as they
cause conflicts with the definition passed to the compiler.

All the features.h definitions (_LARGEFILE64_SOURCE _FILE_OFFSET_BITS=64
and _GNU_SOURCE) are needed by the python glue code too, so they are
moved to BASIC_CFLAGS, and the misleading comments about BASIC_CFLAGS
are removed.

This gives me a clean build on x86_64 (fc12) and mips (Debian).

Subject: perf probe: Usability fixes

Ingo pointed out few perf probe usability related errors during his
review of uprobes.

Since these issues are independent of uprobes, fixing them in a separate
patch.

Subject: perf tools: Fix strlen() bug in perf_event__synthesize_event_type()

The event_type record has a max length for the event name.

It's called MAX_EVENT_NAME.

The name may be truncated to fit the max length. But the header.size still
reflects the original name length. If that length is > MAX_EVENT_NAME, then the
header.size field is bogus. Fix this by using the length of the name after the
potential truncation.

Subject: perf script: Unify the expressions indicating "unknown"

The perf script command uses various expressions to indicate "unknown".

It is unfriendly for user scripts to parse it. So, this patch unifies
the expressions to "[unknown]".

Sample:

Subject: perf script: Add the offset field specifier

Add the offset field specifier 'symoff' to show the offset from
the symbols in the output of perf-script. We can get the more
detailed address information.

Output sample:
ffffffff81467612 irq_return+0x0 => 301ec016b0 _start+0x0
ffffffff81467612 irq_return+0x0 => 301ec016b0 _start+0x0
      301ec016b3 _start+0x3     => 301ec04b70 _dl_start+0x0
ffffffff81467612 irq_return+0x0 => 301ec04b70 _dl_start+0x0
ffffffff81467612 irq_return+0x0 => 301ec04b96 _dl_start+0x26
ffffffff81467612 irq_return+0x0 => 301ec04b9d _dl_start+0x2d
      301ec04beb _dl_start+0x7b => 301ec04c0d _dl_start+0x9d
      301ec04c11 _dl_start+0xa1 => 301ec04bf0 _dl_start+0x80

Subject: perf top: Fix number of samples displayed

In recent versions of perf top, pressing the 'e' key to change the
number of displayed samples had no effect.

The number of samples was still dictated by the size of the terminal
(stdio mode). That was quite annoying because typically only the first
dozen samples really matter.

This patch fixes this.

Subject: perf tools: Remove unnecessary ctype.h inclusion

There are unnecessary #include <ctype.h> out there, and they might cause
a nasty build failure in some environment. As we already have most of
ctype macros in util.h, just get rid of them.

A few of exceptions are util/symbol.c which needs isupper() macro util.h
doesn't provide and perl scripting support code which includes ctype.h
internally.

Subject: perf python: Use attr.watermark in twatch.py

We want to be woken up for every PERF_RECORD_ event, attr.wakeup_events
is only for PERF_RECORD_SAMPLE, so also use attr.watermark = 1 to fix
that.

Subject: perf tools: Remove distclean from Makefile help output

distclean as an alias for clean was removed from the perf Makefile by
commit a3d1ee10d1bf4520af3d44c1aa6cd46956ec4fd7

However, that commit neglected to remove it from the help output of
the perf Makefile, which could result in a user trying the following.

$ cd tools/perf/
$ make help | grep distclean
  distclean		- alias to clean
$ make distclean
make: *** No rule to make target `distclean'.  Stop.

This patch removes it from the Makefile help output.

Subject: perf tool: Fix perf stack to non executable on x86_64

By adding following objects:
  bench/mem-memset-x86-64-asm.o
  bench/mem-memcpy-x86-64-asm.o
the x86_64 perf binary ended up with executable stack.

The reason was that above objects are assembler sourced and are missing the
GNU-stack note section. In such case the linker assumes that the final binary
should not be restricted at all and mark the stack as RWX.

Adding section ".note.GNU-stack" definition to mentioned objects, with all
flags disabled, thus omiting those objects from linker stack flags decision.

Subject: perf doc: Allow producing documentation in a specified output
 directory

Currently we can put the object files in a different directory by using
'O=' comand line argument.

However the generated documentation files don't honor this directive,

This patch fixes that. It's been tested for man target but the others
seems currently broken so no tests have been done on them so far.

Subject: perf tools: fix endianness detection in perf.data

The current version of perf detects whether or not the perf.data file is
written in a different endianness using the attr_size field in the
header of the file. This field represents sizeof(struct perf_event_attr)
as known to perf record. If the sizes do not match, then perf tries the
byte-swapped version. If they match, then the tool assumes a different
endianness.

The issue with the approach is that it assumes the size of
perf_event_attr always has to match between perf record and perf report.
However, the kernel perf_event ABI is extensible.  New fields can be
added to struct perf_event_attr. Consequently, it is not possible to use
attr_size to detect endianness.

This patch takes another approach by using the magic number written at
the beginning of the perf.data file to detect endianness. The magic
number is an eight-byte signature.  It's primary purpose is to identify
(signature) a perf.data file. But it could also be used to encode the
endianness.

The patch introduces a new value for this signature. The key difference
is that the signature is written differently in the file depending on
the endianness. Thus, by comparing the signature from the file with the
tool's own signature it is possible to detect endianness. The new
signature is "PERFILE2".

Backward compatiblity with existing perf.data file is ensured.

Subject: perf record: No build id option fails

A recent refactoring of perf-record introduced the following:

perf record -a -B
Couldn't generating buildids. Use --no-buildid to profile anyway.
sleep: Terminated

I believe the triple negative was meant to be only a double negative.
:-) While I'm there, fixed the grammar on the error message.

Subject: perf tools: Fix build dependency of perf python extension

The perf python extention (perf.so) file lacks its dependencies in the
Makefile so that it cannot be refreshed if one of source files it depends
is changed. Fix it by putting them in a separate file and processing it in
both of Makefile and setup.py.

Subject: perf top: Don't process samples with no valid machine object

The perf sample processing code relies on a valid machine object. Make
sure that this path is only entered when such a object exists.

A counter for samples where no machine object exits is also introduced
to give the user a message about these samples.

Subject: perf tools: Change perf_guest default back to false

Setting perf_guest to true by default makes no sense because the perf
subcommands can not setup guest symbol information and thus not process
and guest samples. The only exception is perf-kvm which changes the
perf_guest value on its own.  So change the default for perf_guest back
to false.

Subject: perf tools: Get rid of ctype.h in symbol.c

The ctype.h in symbol.c was needed because of isupper(). However we now
have it in util.h, it can be changed to use our implementation.

Subject: perf tools: Remove unused functions from debugfs object

Following debugfs object functions are not referenced
within the code:

  int debugfs_valid_entry(const char *path);
  int debugfs_umount(void);
  int debugfs_write(const char *entry, const char *value);
  int debugfs_read(const char *entry, char *buffer, size_t size);
  void debugfs_force_cleanup(void);
  int debugfs_make_path(const char *element, char *buffer, int size);

Removing them.

Subject: perf tools: Add sysfs mountpoint interface

Adding sysfs object to provide sysfs mount information in the same way
as debugfs object does.

The object provides following function:
  sysfs_find_mountpoint

which returns the sysfs mount mount.

Subject: perf tools: Factor out feature op to process header sections

There is individual code for each feature to process header sections.

Adding a function pointer .process to struct feature_ops for keeping the
implementation in separate functions. Code to process header sections is
now a generic function.

Subject: perf tools: cleanup initialization of attr->size

The perf_event_attr size needs to be initialized in all cases because it
captures the ABI version.

This patch moves the initialization of the field from the
perf_event_open() syscall stub to its proper location in the
event_attr_init().

Subject: perf tools: Handle kernels that don't support
 attr.exclude_{guest,host}

Just fall back to resetting those fields, if set, warning the user that
that feature is not available.

If guest samples appear they will just be discarded because no struct
machine will be found and thus the event will be accounted as not
handled and dropped, see 0c09571.

Subject: perf tools: Invert the sample_id_all logic

Instead of requiring that users of perf_record_opts set
.sample_id_all_avail to true, just invert the logic, using
.sample_id_all_missing, that doesn't need to be explicitely initialized
since gcc will zero members ommitted in a struct initialization.

Just like the newly introduced .exclude_{guest,host} feature test.

Subject: perf tools: Allow expressions in __print_symbolic() fields

The __print_symbolic() function takes a sequence of key-value pairs for
pretty-printing a constant.  The new kvm:kvm_exit print fmt uses the
expression:

  __print_symbolic(..., { 0x040 + 1, "DB excp" }, ...)

Currently only atoms are supported and this print fmt fails to parse.
This patch adds support for expressions instead of just atoms so that
0x040 + 1 is parsed successfully.  Also add arg_num_eval() support for
the '+' operator.

Subject: perf tools: fix broken perf record -a mode

The following commit:
b52956c perf tools: Allow multiple threads or processes in record, stat, top

introduced a bug in the thread_map code which caused perf record -a to
not setup system-wide monitoring properly.

$ taskset -c 1 noploop 1000 &
$ perf record -a -C 1 sleep 10
$ perf report -D | tail -20
cycles stats:
           TOTAL events:       4413
            MMAP events:       4025
            COMM events:        340
          SAMPLE events:         48

Here I was expecting about 10,000 samples and not 48.

In system-wide mode, the PID passed to perf_event_open() must be -1 and
it was 0. That caused the kernel to setup a per-process event on PID:0.
Consequently, the number of samples captured does not correspond to the
requested measurement.

The following one-liner fixes the problem for me with or without -C.

I would also suggest to change the malloc() to something that matches
the struct definition. thread_map->map[] is declared as int map[] and
not pid_t map[]. If map[] can only contain pids, then change the struct
definition.

Subject: perf evlist: Restore original errno after open failed

If perf_evsel__open() failed, the errno was set and returned properly.

However since the perf_evlist__open() called close() on fd's for all of
evsel x cpu x thread after the failure, the errno was overridden by
other code (EBADF). So the caller of the function ended up seeing
different error message and getting confused.

Fit it by restoring original return value. Because one of caller of the
function is in the python extension, and it uses system errno
internally, it'd be better restoring the original value rather than
using the return value of the function directly, IMHO (i.e. I'm not a
python expert :)

From b5387528f31d98acedf06e930554b563d87e2383 Mon Sep 17 00:00:00 2001
From: Roberto Agostino Vitillo <ravitillo@lbl.gov>
Date: Thu, 9 Feb 2012 23:21:01 +0100
Subject: perf tools: Add code to support PERF_SAMPLE_BRANCH_STACK

This patch adds:

 - ability to parse samples with PERF_SAMPLE_BRANCH_STACK
 - sort on branches (dso_from, symbol_from, dso_to, symbol_to, mispredict)
 - build histograms on branches

Subject: perf record: Add support for sampling taken branch

This patch adds a new option to enable taken branch stack
sampling, i.e., leverage the PERF_SAMPLE_BRANCH_STACK feature
of perf_events.

There is a new option to active this mode: -b.
It is possible to pass a set of filters to select the type of
branches to sample.

The following filters are available:

 - any : any type of branches
 - any_call : any function call or system call
 - any_ret : any function return or system call return
 - any_ind : any indirect branch
 - u:  only when the branch target is at the user level
 - k: only when the branch target is in the kernel
 - hv: only when the branch target is in the hypervisor

Filters can be combined by passing a comma separated list
to the option:

$ perf record -b any_call,u -e cycles:u branchy

Subject: perf report: Add support for taken branch sampling

This patch adds support for taken branch sampling, i.e, the
PERF_SAMPLE_BRANCH_STACK feature to perf report. In other
words, to display histograms based on taken branches rather
than executed instructions addresses.

The new option is called -b and it takes no argument. To
generate meaningful output, the perf.data must have been
obtained using perf record -b xxx ... where xxx is a branch
filter option.

The output shows symbols, modules, sorted by 'who branches
where' the most often. The percentages reported in the first
column refer to the total number of branches captured and
not the usual number of samples.

Here is a quick example.
Here branchy is simple test program which looks as follows:

void f2(void)
{}
void f3(void)
{}
void f1(unsigned long n)
{
  if (n & 1UL)
    f2();
  else
    f3();
}
int main(void)
{
  unsigned long i;

  for (i=0; i < N; i++)
   f1(i);
  return 0;
}

Here is the output captured on Nehalem, if we are
only interested in user level function calls.

$ perf record -b any_call,u -e cycles:u branchy

$ perf report -b --sort=symbol
    52.34%  [.] main                   [.] f1
    24.04%  [.] f1                     [.] f3
    23.60%  [.] f1                     [.] f2
     0.01%  [k] _IO_new_file_xsputn    [k] _IO_file_overflow
     0.01%  [k] _IO_vfprintf_internal  [k] _IO_new_file_xsputn
     0.01%  [k] _IO_vfprintf_internal  [k] strchrnul
     0.01%  [k] __printf               [k] _IO_vfprintf_internal
     0.01%  [k] main                   [k] __printf

About half (52%) of the call branches captured are from main()
-> f1(). The second half (24%+23%) is split in two equal shares
between f1() -> f2(), f1() ->f3(). The output is as expected
given the code.

It should be noted, that using -b in perf record does not
eliminate information in the perf.data file. Consequently, a
typical profile can also be obtained by perf report by simply
not using its -b option.

It is possible to sort on branch related columns:

   - dso_from, symbol_from
   - dso_to, symbol_to
   - mispredict

Subject: perf tools: Enable reading of perf.data files from different ABI rev

This patch allows perf to process perf.data files generated
using an ABI that has a different perf_event_attr struct size,
i.e., a different ABI version.

The perf_event_attr can be extended, yet perf needs to cope with
older perf.data files. Similarly, perf must be able to cope with
a perf.data file which is using a newer version of the ABI than
what it knows about.

This patch adds read_attr(), a routine that reads a
perf_event_attr struct from a file incrementally based on its
advertised size. If the on-file struct is smaller than what perf
knows, then the extra fields are zeroed. If the on-file struct
is bigger, then perf only uses what it knows about, the rest is
skipped.

Subject: perf tools: Fix ABI compatibility bug in print_event_desc()

This patches cleans up local variable types for msz and ret.
They need to be size_t and ssize_t respectively.

It also fixes a bug whereby perf would not read attr struct
with a different size than what it knows about.

Subject: perf tools: Make perf able to read files from older ABIs

This patches provides a way to handle legacy perf.data
files.  Legacy files are those using the older PERFFILE
signature.

For those, it is still necessary to detect endianness but
without comparing their header->attr_size with the
tool's own version as it may be different. Instead, we use
a reference table for all known sizes from the legacy era.

We try all the combinations for sizes and endianness. If we find
a match, we proceed, otherwise we return: "incompatible file
format".

This is also done for the pipe-mode file format.

Subject: perf record: Provide default branch stack sampling mode option

This patch chanegs the logic of the -b, --branch-stack options
of perf record.

Based on users' request, the patch provides a default filter
mode with the -b (or --branch-any) option.  With the option,
any type of taken branches is sampled.

With -j (or --branch-filter), the user can specify any
valid combination of branch types and privilege levels
if supported by the underlying hardware.

The -b (--branch any) is a shortcut for: --branch-filter any.

 $ perf record -b foo

or:

 $ perf record --branch-filter any foo

For more specific filtering:

 $ perf record --branch-filter ind_call,u foo

Subject: perf record: Add HEADER_BRANCH_STACK tag

This patch adds a new feature bit, namely,
HEADER_BRANCH_STACK.  When present, it indicates
that sample records may contain branch stack.

This could be useful to a viewer to switch to
branch mode without having to parse all the
samples or without a specific cmdline option.

This will be used in a subsequent patch to
enhance perf report with branch stacks.

Subject: perf report: Auto-detect branch stack sampling mode

This patch enhances perf report to auto-detect when the
perf.data file contains samples with branch stacks. That way it
is not necessary to use the -b option.

To force branch view mode to off, simply use --no-branch-stack.

Subject: perf report: Remove duplicate annotate choice in branch view mode

This patch removes the duplicated annotate selection when
browsing in branch view mode. If the sym and dso oof the branch
source and target are the same, then only one annotate choice is
proposed.

Subject: perf report: Fix annotate double quit issue in branch view mode

This patch fixes perf report to not go back two levels when
pressing the 'q' key while annotating in branch view mode.

When pressing 'q' in annotate mode and if the branch source
and target belong to different functions, perf now brings
up the annotation popup menu again to offer the option to
annotate the other branch source or target.

As part of the code restructuring in perf_evsel__hists_browse()
we also fix a memory leak on options[] in case of error.

Add rules to generate pre-processed files (just like are available for

from C ones to produce its output in the output directory rather than
in the source tree.

E.g.

  $ make -C tools/perf/ O=/tmp/perf /tmp/perf/builtin-top.i

From 8f707d843c2f4023490a873dbc182f632a3a5906 Mon Sep 17 00:00:00 2001
From: Jiri Olsa <jolsa@redhat.com>
Date: Thu, 15 Mar 2012 20:09:16 +0100
Subject: perf tools: Add config options support for event parsing

Adding a new rule to the event grammar to be able to specify
values of additional attributes of symbolic event.

The new syntax for event symbolic definition is:

event_legacy_symbol:  PE_NAME_SYM '/' event_config '/' |
                      PE_NAME_SYM sep_slash_dc

event_config:         event_config ',' event_term | event_term

event_term:           PE_NAME '=' PE_NAME |
                      PE_NAME '=' PE_VALUE
                      PE_NAME

sep_slash_dc: '/' | ':' |

At the moment the config options are hardcoded to be used for legacy
symbol events to define several perf_event_attr fields. It is:

  'config'   to define perf_event_attr::config
  'config1'  to define perf_event_attr::config1
  'config2'  to define perf_event_attr::config2
  'period'   to define perf_event_attr::sample_period

Legacy events could be now specified as:
  cycles/period=100000/

If term is specified without the value assignment, then 1 is
assigned by default.

From cd82a32e9924d3a82bd27f830755d23e4ded25bc Mon Sep 17 00:00:00 2001
From: Jiri Olsa <jolsa@redhat.com>
Date: Thu, 15 Mar 2012 20:09:17 +0100
Subject: perf tools: Add perf pmu object to access pmu format definition

Adding pmu object which provides interface to pmu's sysfs
event format definition located at:
  ${sysfs_mount}/bus/event_source/devices/${pmu}/format

Following interface is exported:
  struct perf_pmu* perf_pmu__find(char *name);
  - this function returns pmu object, which is then
    passed as a handle to other interface functions

  int perf_pmu__config(struct perf_pmu *pmu, struct perf_event_attr *attr,
                       struct list_head *head_terms);
  - this function configures perf_event_attr struct based
    on pmu's format definitions and config terms data,
    containined in head_terms list.

Parser generator is used to retrive the pmu's format definition.
The generated parser is part of the patch. Added makefile rule
'pmu-parser' to generate the parser code out of the bison/flex
sources.

Added builtin test 'Test perf pmu format parsing', which could
be run like:
	perf test pmu

Subject: perf tools: Add support to specify pmu style event

Added new event rule to the event definition grammar:

event_def: event_pmu |
           ...
event_pmu: PE_NAME '/' event_config '/'

Using this rule, event could be now specified like:
  cpu/config=1,config1=2,config2=3/u

where pmu name 'cpu' is looked up via following path:
  ${sysfs_mount}/bus/event_source/devices/${pmu}

and config options are bound to the pmu's format definiton:
  ${sysfs_mount}/bus/event_source/devices/${pmu}/format

The hardcoded config options still stays and have precedence
over any format field defined with same name.

Subject: perf stat: Fix event grouping on forked task

When event group is enabled for forked task (i.e. no target task was
specified) all events were disabled and marked ->enable_on_exec.
However they are not counted at all since only group leader will be
enabled on exec actually. So the result looked like below:

 $ ./perf stat --group -- sleep 1

 Performance counter stats for 'sleep 1':

          0.554926 task-clock                #    0.001 CPUs utilized
     <not counted> context-switches
     <not counted> CPU-migrations
     <not counted> page-faults
     <not counted> cycles
   <not supported> stalled-cycles-frontend
   <not supported> stalled-cycles-backend
     <not counted> instructions
     <not counted> branches
     <not counted> branch-misses

       1.001228093 seconds time elapsed

Fix it by disabling group leader only.

Subject: perf tools: Do not disable members of group event

When event group is enabled for forked task (i.e. no target task/cpu
was specified) all events were disabled and marked ->enable_on_exec.
However they wouldn't be counted at all since only group leader will
be enabled on exec actually.

In contrast to perf stat, perf record doesn't have a real problem
as it enables all the event before proceeding. But it needs to be
fixed anyway IMHO.

Subject: perf ui browser: Add 's' key to filter by symbol name

Now user can enter symbol name interested via ui_browser__input_window,
and perf can process it using hists__filter_by_symbol(). Giving empty
symbol (by pressing 's' followed by ENTER) will disable the filtering.

Subject: perf report: Add a simple GTK2-based 'perf report' browser

This patch adds a simple GTK2-based browser to 'perf report' that's
based on the TTY-based browser in builtin-report.c.

To launch "perf report" using the new GTK interface just type:

  $ perf report --gtk

The interface is somewhat limited in features at the moment:

  - No callgraph support

  - No KVM guest profiling support

  - No color coding for percentages

  - No sorting from the UI

  - ..and many, many more!

That said, I think this patch a reasonable start to build future features on.

We're freeing the token in any case so simplify the exit path by
unifying it.

Subject: perf tools: Fix modifier to be applied on correct events

The event modifier needs to be applied only on the event definition it
is attached to.

The current state is that in case of multiple events definition (in
single '-e' option, separated by ',') all will get modifier of the last
one.

Fixing this by adding separated list for each event definition, so the
modifier is applied only to proper event(s). Added automated test to
catch this, plus some other modifier tests.

+     - Assume YYFAIL is not used.  It's too flawed to consider.  See
+       <http://lists.gnu.org/archive/html/bison-patches/2009-12/msg00024.html>
+       for details.  YYERROR is fine as it does not invoke this
+       function.
+     - If this state is a consistent state with a default action, then
+       the only way this function was invoked is if the default action
+       is an error action.  In that case, don't check for expected
+       tokens because there are none.
+     - The only way there can be no lookahead present (in yychar) is if
+       this state is a consistent state with a default action.  Thus,
+       detecting the absence of a lookahead is sufficient to determine
+       that there is no unexpected or expected token to report.  In that
+       case, just report a simple "syntax error".
+     - Don't assume there isn't a lookahead just because this state is a
+       consistent state with a default action.  There might have been a
+       previous inconsistent state, consistent state with a non-default
+       action, or user semantic action that manipulated yychar.
+     - Of course, the expected token list depends on states to have
+       correct lookahead information, and it depends on the parser not
+       to perform extra reductions after fetching a lookahead from the
+       scanner and before detecting a syntax error.  Thus, state merging
+       (from LALR or IELR) and default reductions corrupt the expected
+       token list.  However, the list is correct for canonical LR with
+       one exception: it will still contain any token that will not be
+       accepted due to an error action in a later state.

From 4bf9ce1b5ecffffeb8b9d7e925bac3e6b10109aa Mon Sep 17 00:00:00 2001
From: Jiri Olsa <jolsa@redhat.com>
Date: Thu, 22 Mar 2012 14:37:26 +0100
Subject: perf diff: Fix to work with new hists design

The perf diff command is broken since:
  perf hists: Threaded addition and sorting of entries
  commit 1980c2ebd7020d82c024b8c4046849b38e78e7da

Several places were broken:
  - hists data need to be collected into opened sessions instead
    of into events
  - session's hists data need to be initialized properly when the
    session is created
  - hist_entry__pcnt_snprintf: the percentage and displacement
    buffer preparation must not use 'ret' because it's used
    as a pointer to the final buffer

Subject: bitops: rename for_each_set_bit_cont() in favor of analogous list.h
 function

This renames for_each_set_bit_cont() to for_each_set_bit_from() because
it is analogous to list_for_each_entry_from() in list.h rather than
list_for_each_entry_continue().

This doesn't remove for_each_set_bit_cont() for now.

Subject: perf tools: Switch module.h into export.h

When merged to Linus's latest tree the perf build is broken
due to following change in lib/rbtree.c object:

  lib: reduce the use of module.h wherever possible
  commit 8bc3bcc93a2b4e47d5d410146f6546bca6171663
  Author: Paul Gortmaker <paul.gortmaker@windriver.com>
  Date:   Wed Nov 16 21:29:17 2011 -0500

We need to move module.h header into export.h.

Subject: perf tools: Fix display of first level of callchains

The callchain stdio mode display was written using a sorted by symbol
report. In this mode we have only one callchain root per hist so we
forgot to handle cases where we have multiple callchain root, as in per
dso sorting for example.

Fix this by handling these roots like any other branch, with the hist as
the parent.

Before:

     1.97%  libpthread-2.12.1.so
            |
            --- __libc_write
                create_worker
                bench_sched_messaging
                cmd_bench
                run_builtin
                main
                __libc_start_main

            |
            --- __libc_read
                create_worker
                bench_sched_messaging
                cmd_bench
                run_builtin
                main
                __libc_start_main

After:

     1.97%  libpthread-2.12.1.so
            |
            |--36.97%-- __libc_write
            |          create_worker
            |          bench_sched_messaging
            |          cmd_bench
            |          run_builtin
            |          main
            |          __libc_start_main
            |
            |--31.47%-- __libc_read
            |          create_worker
            |          bench_sched_messaging
            |          cmd_bench
            |          run_builtin
            |          main
            |          __libc_start_main
           ...

Single roots keep their entry without percentage because they have
the same overhead than the hist they refer to. ie: 100% in fractal
mode and the percentage of the hist in graph mode:

     0.00%  [k] reschedule_interrupt
            |
            --- default_idle
                amd_e400_idle
                cpu_idle
                start_secondary

Subject: perf tools: Fix bug in raw sample parsing

In perf_event__parse_sample(), the array variable was not incremented
by the amount of data used by the raw_data.

That was okay until we added PERF_SAMPLE_BRANCH_STACK which depends on
the array variable pointing to the beginning of the branch stack data.

But that was not the case if branch stack was combined with raw mode
sampling. That led to bogus branch stack addresses and count.

The bug would show up with:
$ perf record -R -b foo

This patch fixes the problem by correctly moving the array pointer
forward for RAW samples.

Subject: perf probe: Finder fails to resolve function name to address

If DIE entries corresponding to declarations appear before definition
entry, probe finder returns error instead of continuing to look further
for a definition entry.

This patch ensures we reach to the DIE entry corresponding to the
definition and get the function address.

V2: A simpler solution based on Masami's suggestion.

We were not noticing it because symbol__inc_addr_samples was erroneously
dropping samples that hit the last byte in a function.

Working on a fix for a problem reported by David Miller, Stephane
Eranian and Sorin Dumitru, where addresses < sym->start were causing
problems, I noticed this other problem.

-       for details.  YYERROR is fine as it does not invoke this
-       function.
-     - If this state is a consistent state with a default action, then
-       the only way this function was invoked is if the default action
-       is an error action.  In that case, don't check for expected
-       tokens because there are none.
-     - The only way there can be no lookahead present (in yychar) is if
-       this state is a consistent state with a default action.  Thus,
-       detecting the absence of a lookahead is sufficient to determine
-       that there is no unexpected or expected token to report.  In that
-       case, just report a simple "syntax error".
-     - Don't assume there isn't a lookahead just because this state is a
-       consistent state with a default action.  There might have been a
-       previous inconsistent state, consistent state with a non-default
-       action, or user semantic action that manipulated yychar.
-     - Of course, the expected token list depends on states to have
-       correct lookahead information, and it depends on the parser not
-       to perform extra reductions after fetching a lookahead from the
-       scanner and before detecting a syntax error.  Thus, state merging
-       (from LALR or IELR) and default reductions corrupt the expected
-       token list.  However, the list is correct for canonical LR with
-       one exception: it will still contain any token that will not be
-       accepted due to an error action in a later state.
