[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling, I guess the changes are minor of affect just some
non-core feature, so it is you call if you prefer to pull it into perf/urgent instead.

Best Regards,

  perf kvm stat live: Enable events copying (2014-10-15 17:39:03 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

* Add a visual cue for toggle zeroing of samples in 'perf top' (Taeung Song)

* Fix for double free in 'perf stat' when using some specific invalid
  command line combo (Yasser Shalabi)

Infrastructure:

* Add option to copy events when queuing for sorting across cpu buffers
  and enable it for 'perf kvm stat live', to avoid having events left
  in the queue pointing to the ring buffer be rewritten in high volume
  sessions.  (Alexander Yarygin, improving work done by David Ahern):

* Document sysfs events/ interfaces (Cody P Schafer)

* Add support to new style format of kernel PMU event. (Kan Liang)

* Fix typos in perf/Documentation (Masanari Iida)

* Improve callchains when using libunwind (Namhyung Kim)

[PATCH 01/15] perf top: Add a visual cue for toggle zeroing of samples

[Arnaldo Carvalho de Melo]

From: Taeung Song <treeze.taeung@gmail.com>

When 'perf top' is run, one can't easily find a difference
between -z option and normal output.
So I added a visual cue to know whether it is the zeroing or not.

Output is as below.

Before:
 $ perf top

 Samples: 61K of event 'cycles', Event count (approx.): 3908136933
 Overhead  Shared Object                       Symbol
    1.42%  firefox                             [.] 0x0000000000011e76
    1.32%  libpthread-2.17.so                  [.] pthread_mutex_lock

If you press key 'z' or run with zero option like '$ perf top --zero', it is as below.

After:
 Samples: 61K of event 'cycles', Event count (approx.): 3908136933 [z]
 Overhead  Shared Object                       Symbol
    1.42%  firefox                             [.] 0x0000000000011e76
    1.32%  libpthread-2.17.so                  [.] pthread_mutex_lock

[PATCH 02/15] perf Documentation: sysfs events/ interfaces

[Arnaldo Carvalho de Melo]

From: Cody P Schafer <dev@codyps.com>

Add documentation for the <event>, <event>.scale, and <event>.unit
files in sysfs.

	<event>.scale and <event>.unit were undocumented.
	<event> was previously documented only for specific powerpc pmu events.

[PATCH 03/15] perf Documentation: Remove Ruplicated docs for powerpc cpu specific events

[Arnaldo Carvalho de Melo]

From: Cody P Schafer <dev@codyps.com>

Listing specific events doesn't actually help us at all here because:
 - these events actually vary between different ppc processors, they
   aren't garunteed to be present.
 - the documentation of the (generic) file contents is now superceded by the
   docs for arbitrary event file contents.

[PATCH 04/15] Revert "perf tools: Default to cpu// for events v5"

[Arnaldo Carvalho de Melo]

From: Kan Liang <kan.liang@intel.com>

This reverts commit 50e200f07948 ("perf tools: Default to cpu// for
events v5")

The fixup cannot handle the case that
new style format(which without //) mixed with
other different formats.

For example,
group events with new style format: {mem-stores,mem-loads}
some hardware event + new style event: cycles,mem-loads
Cache event + new style event: LLC-loads,mem-loads
Raw event + new style event:
cpu/event=0xc8,umask=0x08/,mem-loads
old style event and new stytle mixture: mem-stores,cpu/mem-loads/

[PATCH 05/15] perf tools: Parse the pmu event prefix and suffix

[Arnaldo Carvalho de Melo]

From: Kan Liang <kan.liang@intel.com>

There are two types of event formats for PMU events. E.g. el-abort OR
cpu/el-abort/. However, the lexer mistakenly recognizes the simple style
format as two events.

The parse_events_pmu_check function uses bsearch to search the name in
known pmu event list. It can tell the lexer that the name is a PE_NAME
or a PMU event name prefix or a PMU event name suffix. All these
information will be used for accurately parsing kernel PMU events.

The pmu events list will be read from sysfs at runtime.

Note: Currently, the patch only want to handle the PMU event name as
"a-b" and "a". The only exception, "stalled-cycles-frontend" and
"stalled-cycles-fronted", are already hardcoded in lexer.

[PATCH 06/15] perf tools: Add support to new style format of kernel PMU event

[Arnaldo Carvalho de Melo]

From: Kan Liang <kan.liang@intel.com>

Add new rules for kernel PMU event.

Currently, the patch only want to handle the PMU event name as "a-b" and
"a".

event_pmu:
PE_KERNEL_PMU_EVENT sep_dc
|
PE_PMU_EVENT_PRE '-' PE_PMU_EVENT_SUF sep_dc

PE_KERNEL_PMU_EVENT token is for
cycles-ct/cycles-t/mem-loads/mem-stores.

The prefix cycles is mixed up with cpu-cycles.  loads and stores are
mixed up with cache event So they have to be hardcode in lex.

PE_PMU_EVENT_PRE and PE_PMU_EVENT_SUF tokens are for other PMU events.

The lex looks generic identifier up in the table and return the matched
token. If there is no match, generic PE_NAME token will be return.

Using the rules, kernel PMU event could use new style format without //

so you can use:

  perf record -e mem-loads ...

instead of:

  perf record -e cpu/mem-loads/

[PATCH 07/15] perf test: Add test case for pmu event new style format

[Arnaldo Carvalho de Melo]

From: Kan Liang <kan.liang@intel.com>

Add test case in automated tests suite. It checks not only the two types
of pmu event stytle formats "pmu_event_name" and "cpu/pmu_event_name/",
but also the different formats mixtures which are more likely to trigger
parse issue.

The patch set including this one has been tested by the perf automated
test:

   ./perf test parse -v"

On haswell, ivybridge and Romley platform.

The patch set also has been tested on haswell by the following script.

Note: please make sure that your test system support TSX and
L1-dcache-loads events. Otherwise, you may want to change the events to
other pmu events.

  [lk@localhost ~]$ cat perf_style_test.sh
  # hardware events + kernel pmu event with different style
  perf stat -x, -e cycles,mem-stores,tx-start sleep 2
  perf stat -x, -e cpu-cycles,cycles-ct,cycles-t sleep 2
  perf stat -x, -e cycles,cpu/cycles-ct/,cpu/cycles-t/ sleep 2
  perf stat -x, -e instructions,cpu/tx-start/ sleep 2
  perf stat -x, -e '{cycles,tx-start}' sleep 2
  perf stat -x, -e '{cycles,cpu/tx-start/}' sleep 2

  # HW Cache event + kernel pmu event with different style
  perf stat -x, -e L1-dcache-loads,cpu/mem-stores/,tx-start sleep 2
  perf stat -x, -e L1-dcache-loads,mem-stores,cpu/tx-start/ sleep 2
  perf stat -x, -e '{L1-dcache-loads,mem-stores}' sleep 2
  perf stat -x, -e '{L1-dcache-loads,cpu/tx-start/}' sleep 2

  # Raw event + kernel pmu event with different style:
  perf stat -x, -e cpu/event=0xc0,umask=0x00/,mem-loads,cpu/mem-stores/ sleep 2
  perf stat -x, -e cpu/event=0xc0,umask=0x00/,tx-start,cpu/el-start/ sleep 2
  perf stat -x, -e '{cpu/event=0xc0,umask=0x00/,tx-start}' sleep 2

[PATCH 08/15] perf evlist: Fix for double free in tools/perf stat

[Arnaldo Carvalho de Melo]

From: Yasser Shalabi <yassershalabi@gmail.com>

Fix for double free bug in tools/perf due to dangling thread_map pointer
in perf_evlist struct.

Code path excercised when perf stat -C switch is used but not set and is
followed by another switch.

Example:

  perf stat -C -e.

[PATCH 09/15] perf report: Set callchain_param.record_mode for future use

[Arnaldo Carvalho de Melo]

From: Namhyung Kim <namhyung@kernel.org>

Normally the callchain_param.record_mode is used only for record path.
But as it might need to prepare something for dwarf unwinding, setup
this info for perf report too.

[PATCH 10/15] perf callchain: Create an address space per thread

[Arnaldo Carvalho de Melo]

From: Namhyung Kim <namhyung@kernel.org>

The unw_addr_space_t in libunwind represents an address space to be used
for stack unwinding.  It doesn't need to be create/destory everytime to
unwind callchain (as in get_entries) and can have a same lifetime as
thread (unless exec called).

So move the address space construction/destruction logic to the thread
lifetime handling functions.  This is a preparation to enable caching in
the unwind library.

Note that it saves unw_addr_space_t object using thread__set_priv().  It
seems currently only used by perf trace and perf kvm stat commands which
don't use callchain.

[PATCH 14/15] perf session: Add option to copy events when queueing

[Arnaldo Carvalho de Melo]

From: Alexander Yarygin <yarygin@linux.vnet.ibm.com>

When processing events the session code has an ordered samples queue
which is used to time-sort events coming in across multiple mmaps. At a
later point in time samples on the queue are flushed up to some
timestamp at which point the event is actually processed.

When analyzing events live (ie., record/analysis path in the same
command) there is a race that leads to corrupted events and parse errors
which cause perf to terminate. The problem is that when the event is
placed in the ordered samples queue it is only a reference to the event
which is really sitting in the mmap buffer. Even though the event is
queued for later processing the mmap tail pointer is updated which
indicates to the kernel that the event has been processed. The race is
flushing the event from the queue before it gets overwritten by some
other event. For commands trying to process events live (versus just
writing to a file) and processing a high rate of events this leads to
parse failures and perf terminates.

Examples hitting this problem are 'perf kvm stat live', especially with
nested VMs which generate 100,000+ traces per second, and a command
processing scheduling events with a high rate of context switching --
e.g., running 'perf bench sched pipe'.

This patch offers live commands an option to copy the event when it is
placed in the ordered samples queue.

Based on a patch from David Ahern <dsahern@gmail.com>

[PATCH 15/15] perf kvm stat live: Enable events copying

[Arnaldo Carvalho de Melo]

From: Alexander Yarygin <yarygin@linux.vnet.ibm.com>

Process of analyzing events caused by 2 functions: mmap_read() and
finished_round().

During mmap_read(), perf receives events from shared memory, queues
their pointers for further processing in finished_round() and notifies
the kernel that the events have been processed.

By the time when finished_round() is invoked, queued events can be
overwritten by the kernel, so the finished_round() occurs on potentially
corrupted memory.

Since there is no place where the event can be safely consumed, let's
copy events when queueing.
