hi,
sending another version of stat scripting.
v3 changes:
- added attr update event to handle unit,scale,name for event
it fixed the uncore_imc_1/cas_count_read/ record/report
- perf report -D now displays stat related events
- some minor and changelog fixes
v2 changes:
- rebased to latest Arnaldo's perf/core
- patches 1 to 11 already merged in
- added --per-core/--per-socket/-A options for perf stat report
command to allow custom aggregation in stat report, please
check new examples below
- couple changelogs changes
The initial attempt defined its own formula lang and allowed
triggering user's script on the end of the stat command:
http://marc.info/?l=linux-kernel&m=136742146322273&w=2
This patchset abandons the idea of new formula language
and rather adds support to:
- store stat data into perf.data file
- add python support to process stat events
Basically it allows to store stat data into perf.data and
post process it with python scripts in a similar way we
do for sampling data.
The stat data are stored in new stat, stat-round, stat-config user events.
stat - stored for each read syscall of the counter
stat round - stored for each interval or end of the command invocation
stat config - stores all the config information needed to process data
so report tool could restore the same output as record
The python script can now define 'stat__<eventname>_<modifier>' functions
to get stat events data and 'stat__interval' to get stat-round data.
See CPI script example in scripts/python/stat-cpi.py.

Introduce perf_event__synthesize_thread_map2 function to
synthesize struct thread_map.
The perf_event__synthesize_thread_map is already taken
for synthesizing complete threads data (comm/mmap/fork).

Adding stat config event to pass/store stat config data,
so report tools (report/script) know how to interpret
stat data.
The config data are stored in 'tag|value' way to allow
easy extension and backward compatibility.

It'll server as base event for additional event attributes
details, that are not part of the attr event.
At the moment this event is just dummy one without specific
functionality. The type value will distinguish the update
event details. It comes in following patches.
The idea for this event is to be extensible for any update
that attr event might need in the future.

Adding name type attr update event, that stores/transfer
events name. Event's name is stored within perf.data's
EVENT_DESC feature, but we don't have if we get report
data from pipe.

Introducing stat feature to mark perf.data as created by
perf stat record command. It contains no data.
It's needed for report tools (report/script) to differentiate
sampling data from stat data, because they need to be treated
in a different way.

Because following stat patches use id_offset together
with priv pointer.

Store event IDs in evlist object so it get stored
into perf.data file.
Also making perf_evlist__id_add_fd global.

so we can't allow -r option in stat record.

Adding data arg to cpu_map__build_map callback, so we could
pass data along to the callback. It'll be needed in following
patches to retrieve topology info from perf.data.

Currently any time we need to access socket or core id for
given cpu, we access the sysfs topology file.
Adding cpus_aggr_map cpu_map to cache those entries.

Adding processing of stat and stat round events.
The stat data com in stat events, using generic
function process_stat_round_event to store data
under perf_evsel object.
The stat-round events comes each interval or as
last event in non interval mode. The function
process_stat_round_event process stored data
for each perf_evsel object and print it out.

Allowing to override record aggr_mode. It's possible
to use perf stat like:
$ perf stat report -A
$ perf stat report --per-core
$ perf stat report --per-socket
To customize the recorded aggregate mode regardless
what was used during the stat record command.

Add support to get stat events data in perf python scripts.
The python script shall implement following
new interface to process stat data:
def stat__<event_name>_[<modifier>](cpu, thread, time, val, ena, run):
- is called for every stat event for given counter,
if user monitors 'cycles,instructions:u" following
callbacks should be defined:
def stat__cycles(cpu, thread, time, val, ena, run):
def stat__instructions_u(cpu, thread, time, val, ena, run):
def stat__interval(time):
- is called for every interval with its time,
in non interval mode it's called after last
stat event with total meassured time in ns
The rest of the current interface stays untouched..
Please check example CPI metrics script in following patch
with command line examples in changelogs.

Adding stat-cpi.py as an example of how to do stat scripting.
It computes the CPI metrics from cycles and instructions
events.
Following stat record/report/script combinations could be used:
- get CPI for given workload
$ perf stat -e cycles,instructions record ls
SNIP
Performance counter stats for 'ls':
2,904,431 cycles
3,346,878 instructions # 1.15 insns per cycle

Hi Jirka
I'm doing some test with the perf/stat_script tree.
Here are the issues I found so far.
1 test case failed to build:
CC tests/stat.o
tests/stat.c: In function âtest__synthesize_statâ:
tests/stat.c:82:3: error: missing initializer for field âenaâ of
âstruct <anonymous>â [-Werror=missing-field-initializers]

u64 ena;
^
tests/stat.c:83:3: error: missing initializer for field ârunâ of
âstruct <anonymous>â [-Werror=missing-field-initializers]
.run = 300,
^
In file included from tests/stat.c:5:0:
/home/lk/group_read/test/perf/tools/perf/util/counts.h:11:8:
note: ârunâ declared here
u64 run;
^

make[2]: *** [tests] Error 2

make: *** [all] Error 2
2. it still doesn't work well with uncore event.
Here is an example:
sudo ./perf stat -e uncore_imc_1/cas_count_read/ -a --interval-print 100
--per-socket record -- sleep 1
# time socket cpus counts unit events
0.100231142 S0 1 0.04 MiB uncore_imc_1/cas_count_read/
0.100231142 S1 1 0.08 MiB uncore_imc_1/cas_count_read/
0.200583556 S0 1 0.02 MiB uncore_imc_1/cas_count_read/
0.200583556 S1 1 0.02 MiB uncore_imc_1/cas_count_read/
sudo ./perf stat report --per-socket
# time socket cpus counts unit events
0.100231142 S0 36 0.12 MiB uncore_imc_1/cas_count_read/
0.100231142 S1 28 <not counted>
MiB uncore_imc_1/cas_count_read/
0.200583556 S0 36 0.04 MiB uncore_imc_1/cas_count_read/
0.200583556 S1 28 <not counted>
MiB uncore_imc_1/cas_count_read/
The results are not consistent.
I checked the perf report -D result. It looks the wrong CPU id is stored.
In my system, the uncore event should be monitored in CPU 0 and CPU 19
But it shows CPU0 and CPU1.
0x520 [0x30]: PERF_RECORD_STAT
... id 22385, cpu 0, thread 0
0x550 [0x30]: PERF_RECORD_STAT
... id 22386, cpu 1, thread 0
3. I think you have already handled new record type for perf stat record.
But the "unhandled!" message still show in the perf report -D.
0x598 [0x30]: PERF_RECORD_STAT
... id 22385, cpu 0, thread 0
... value 1752, enabled 501473097, running 501473097
: unhandled! <-------
4. Core dump when applying --per-core -a for stat record.
sudo ./perf stat -e 'cycles' --per-core -a record sleep 1
** Error in `./perf': corrupted double-linked list: 0x00000000036eb560 **
======= Backtrace: =========
/lib64/libc.so.6[0x3002e7bbe7]
/lib64/libc.so.6[0x3002e7d2b5]
./perf(perf_env__exit+0xfd)[0x484d1d]
./perf[0x47c45f]
./perf(main+0x610)[0x421ac0]
/lib64/libc.so.6(__libc_start_main+0xf5)[0x3002e21b45]
./perf[0x421bd9]
5. perf stat record may not monitor on specific CPU/whole-system.
However, perf stat report can be set to aggregate per core/socket.
If so, there is problem to show the data.
I think we need some warning here.
For example,
sudo ./perf stat -e 'cycles' record sleep 1
Performance counter stats for 'sleep 1':
858,928 cycles
1.001120735 seconds time elapsed
sudo ./perf stat report -A
Performance counter stats for '/home/lk/group_read/test/perf/
tools/perf/perf stat -e cycles record sleep 1':
CPU-1 858,928 cycles
1.001120735 seconds time elapsed

it's the pmu's cpumask I did not take into account
I think we'll have to send cpumask as attr_update

yep, I was wondering about that as well.. but it's not 'handled' in perf report,
it just displays the raw output of the event.. but I think we could remove that
not to confuse
and perhaps we could also add -D for perf stat report

could not reproduce this one.. any chance you could compile with
DEBUG=1 and re-run in gdb for more details? like which of the
frees got crazy.. ?

yep, we need to disable those options for process data

The crash is not caused by this patch set. It's also a bug in current perf.
I've submitted a patch for that.
