[PATCH 00/12 v2] perf lock: New subcommand "perf lock", for analyzing lock statistics

[PATCH 00/12 v2] perf lock: New subcommand "perf lock", for analyzing lock statistics

[Hitoshi Mitake]

Adding new subcommand "perf lock" to perf.

I made this patch series on
latest perf/core of tip (ef12a141306c90336a3a10d40213ecd98624d274),
so please apply this series to perf/core.

This patch is version 2.
I removed lack of util/include/linux/hash.h
and compile error of builtin-lock.c on 32bit env.

Sorry for my slow work, Frederic and Ingo.
I have a lot of rest ToDos,
but finally perf lock can provide minimal functions for analyzing lock statistics.

This series requires one more revirting patch.
But it is very temporary solution,
so I cannot make this series include it.
I'll send it as reply to this cover letter later only for testing,
if you are interested in testing this series,
you need to apply it.

Hitoshi Mitake (11):
  perf tools: Add __data_loc support
  perf: Add util/include/linuxhash.h to include hash.h of kernel
  lockdep: Add information of file and line where lock inited to struct
    lockdep_map
  lockdep: Add file and line to initialize sequence of spinlock
  lockdep: Add file and line to initialize sequence of rwlock
  lockdep:  Add file and line to initialize sequence of rwsem
  lockdep:  Add file and line to initialize sequence of rwsem (x86)
  lockdep: Add file and line to initialize sequence of mutex
  lockdep: Fix the way to initialize class_mutex for information of
    file and line
  perf lock: Enhance information of lock trace events
  perf lock: New subcommand "perf lock", for analyzing lock statistics

[PATCH v2 01/11] perf tools: Add __data_loc support

[Hitoshi Mitake]

This patch is required to test the next patch for perf lock.

At 064739bc4b3d7f424b2f25547e6611bcf0132415 ,
support for the modifier "__data_loc" of format is added.

But, when I wanted to parse format of lock_acquired (or some
event else), raw_field_ptr() did not returned correct pointer.

So I modified raw_field_ptr() like this patch. Then
raw_field_ptr() works well.

[PATCH v2 02/11] perf: Add util/include/linuxhash.h to include hash.h of kernel

[Hitoshi Mitake]

linux/hash.h, hash header of kernel, is also useful for perf.

util/include/linuxhash.h includes linux/hash.h, so we can use
hash facilities (e.g. hash_long()) in perf now.

[PATCH v2 03/11] lockdep: Add information of file and line where lock inited to struct lockdep_map

[Hitoshi Mitake]

__FILE__ and __LINE__ where lock instances initialized are useful information
for profiling lock behaviour.
This patch adds these to struct lockdep_map.

The impact of this patch is making lockdep_init_map() macro.
Former lockdep_init_map() was renamed to __lockdep_init_map().
And lockdep_init_map() is a simple wrapper
to pass __FILE__ and __LINE__ to __lockdep_init_map() now.

[PATCH v2 04/11] lockdep: Add file and line to initialize sequence of spinlock

[Hitoshi Mitake]

spinlock has two way to be initialized.
1: the macros DEFINE_{SPIN,RW}LOCK for statically defined locks
2: the functions {spin_,rw}lock_init() for locks on dynamically allocated memory

This patch modifies these two initialize sequences
for adding __FILE__ and __LINE__ to lockdep_map.

[PATCH v2 09/11] lockdep: Fix the way to initialize class_mutex for information of file and line

[Hitoshi Mitake]

This patch adds __FILE__ and __LINE__ to arguments passed for
__mutex_init() called in __class_register().
This affects to lockdep_map of class_mutex of struct class_private,
and these will be used to make trace lock events more human friendly.

[PATCH v2 11/11] perf lock: New subcommand "perf lock", for analyzing lock statistics

[Hitoshi Mitake]

Adding new subcommand "perf lock" to perf.
I have a lot of rest ToDos,
but now perf lock can provide minimal functions for analyzing lock statistics.

This patch containts some over-80 chars line,
but I judged that removing these lines makes
dirty points for readability.

Revert "perf record: Intercept all events"

[Hitoshi Mitake]

ONLY FOR TEST USE!!!

This reverts commit f5a2c3dce03621b55f84496f58adc2d1a87ca16f.

This patch is required for making "perf lock rec" work.
The commit f5a2c3dce0 changes write_event() of builtin-record.c .
And changed write_event() sometimes doesn't stop with perf lock rec.

I'm researching what makes write_event() loop infinity,
and noticed that there are some events with event_t->header.size == 0.
But the detail of the problem,
like kind of these events, isn't clear...

*** I cannot sing this! ***

Re: [PATCH 00/12 v2] perf lock: New subcommand "perf lock", for analyzing lock statistics

[Ingo Molnar]

[-- Attachment #1: Type: text/plain, Size: 3459 bytes --]


FYI, i've applied a file/line-less version of 'perf lock' to perf/core today.

The basic workflow is the usual:

  perf lock record sleep 1     # or some other command
  perf lock report             # or 'perf lock trace'

[ I think we can do all the things that file/line can do with a less intrusive 
  (and more standard) call-site-IP based approach. For now we can key off the 
  names of the locks, that's coarser but also informative and allows us to 
  progress.

  I've renamed 'perf lock prof' to 'perf lock report' - which is more in line 
  with other perf tools. ]

The tool clearly needs more work at the moment: i have tried perf lock on a 16 
cpus box, and it was very slow, while it didnt really record all that many 
events to justify the slowdown. A simple:

  perf lock record sleep 1

makes the system very slow and requires a Ctrl-C to stop:

 # time perf lock record sleep 1
 ^C[ perf record: Woken up 0 times to write data ]
 [ perf record: Captured and wrote 5.204 MB perf.data (~227374 samples) ]

  real	0m11.941s
  user	0m0.020s
  sys	0m11.661s

(The kernel config i used witht that is attached.)

My suspicion is that the overhead of CONFIG_LOCK_STAT based tracing is way too 
high at the moment, and needs to be reduced. I have removed the '-R' option 
from perf lock record (which it got from perf sched where it makes sense but 
here it's not really needed and -R further increases overhead), but that has 
not solved the slowdown.

'top' shows this kind of messy picture of a high-overhead system:

A couple of other details i noticed:

 - 'perf lock' does not show up in the list of commands if one types 'perf'.
   You can fix this by adding it to command-list.txt.

 - i think we should add a reference to 'perf lock' in the config 
   LOCK_STAT entry's help text in lib/Kconfig.debug - so that people can see 
   what tool to use with lock statistics.

 - perf report should be used to further reduce the overhead of 
   CONFIG_LOCK_STAT. If we want people to use this to tune for performance, we 
   want it to be exceptionally fast. Both the perf-lock-running and
   perf-lock-not-running cases should be optimized. (Perhaps dynamic patching
   techniques should be considered as well.)

 - we waste 30 characters for the 'ID' column in perf lock report, which is in 
   all hexa, while no human would ever really read it, and would rarely rely 
   on it as well. Should be removed and only added back on option request or 
   so.

Thanks,

	Ingo

perf tools: Add __data_loc support

This patch is required to test the next patch for perf lock.

At 064739bc4b3d7f424b2f25547e6611bcf0132415 ,
support for the modifier "__data_loc" of format is added.

But, when I wanted to parse format of lock_acquired (or some
event else), raw_field_ptr() did not returned correct pointer.

So I modified raw_field_ptr() like this patch. Then
raw_field_ptr() works well.

perf: Add util/include/linuxhash.h to include hash.h of kernel

linux/hash.h, hash header of kernel, is also useful for perf.

util/include/linuxhash.h includes linux/hash.h, so we can use
hash facilities (e.g. hash_long()) in perf now.

perf lock: Introduce new tool "perf lock", for analyzing lock statistics

Adding new subcommand "perf lock" to perf.

I have a lot of remaining ToDos, but for now perf lock can
already provide minimal functionality for analyzing lock
statistics.

perf lock: Clean up various details

Fix up a few small stylistic details:

 - use consistent vertical spacing/alignment
 - remove line80 artifacts
 - group some global variables better
 - remove dead code

Plus rename 'prof' to 'report' to make it more in line with other
tools, and remove the line/file keying as we really want to use
IPs like the other tools do.

Hmm, -R is mandatory if you want the raw sample events, otherwise the
event is just a counter.

May be you mean -M ? Sure -M is going to be a noticeable overhead
in 16 cores.

Anyway, I'm looking closely into improving the lock events to
reduce all this overhead. I'll create a lock_init event so
that we can gather the heavy informations there (especially
the name of the lock).

Also, using TRACE_EVENT_FN lets us register a callback when
a tracepoint gets registered, I'm going to try to synthetize
the missing lock_init() events here.

Yeah, i meant and tested -M.

Ok, thanks for looking into this!

Yeah, overhead is main problem of perf lock now,
I'll work on it with Frederic's new patches, these are awesome.

Thanks, I've fixed these two points and prepared patch.
I'll send it later.

Yes, address of lockdep is optional thing. This should be removed.

[PATCH] perf lock: Fix and add misc documentally things

[Hitoshi Mitake]

I've forgot to add 'perf lock' line to command-list.txt,
so users of perf could not find perf lock when they type 'perf'.

Fixing command-list.txt requires document
(tools/perf/Documentation/perf-lock.txt).
But perf lock is too under construction tool to write document,
so this is something like pseudo document now.

And I wrote description of perf lock at help section of
CONFIG_LOCK_STAT, this will navigate users of lock trace events.
