v2 cover perf stat: Separate shadow counters code

hi,
sending cleanup/move of shadow counters. I need it for my other changes of stat scripting, but I think it can stand alone as a cleanup.

v2 changes:
- move evsel id into 'struct perf_stat'
and change the id functions namespace

Also in:
git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
perf/shadow

I tested on Haswel with limited set of transaction events, but all seemed ok.

thanks,
jirka

PATCH v2 3/9 perf stat: Remove setup_events function

In reply to Jiri Olsa

We can use already existing parse_events interface.

Both transaction_attrs and transaction_limited_attrs are changed to be single strings.

Lemme see if I understand this correctly, this update_shadow_stats() is called only for transaction runs?

It doesn't seem so, so now we will update those stats all the time?

Lemme see if I understand this correctly, this update_shadow_stats() is called only for transaction runs?
It doesn't seem so, so now we will update those stats all the time?

update_shadow_stats is called on currently read/processed counter and based on its 'type' we update various other counters - shadow counters - which are the base for things like IPC in the stat output

So:

- else if (transaction_run && perf_stat_evsel__is(counter, CYCLES_IN_TX))
+ else if (perf_stat_evsel__is(counter, CYCLES_IN_TX))

                update_stats(&runtime_transaction_stats[ctx][cpu], count[0]);

Before we were going to check this _only_ when transaction_run was set, now we are doing it always, or are you saying that perf_stat_evsel__is(counter, CYCLES_IN_TX) will only return true for transaction 'perf stat' usage?

Let me take a look:

Yes, in all cases we, start doing:

   perf_evlist__alloc_stats()
     perf_evsel__alloc_stat_priv()
       perf_evsel__reset_stat_priv()
         perf_stat_evsel_id_init();
           struct perf_stat *ps = evsel->priv;
           ps->id = one of the entries below:

static const char *id_str[PERF_STAT_EVSEL_ID__MAX] = {

        ID(NONE,                x),
        ID(CYCLES_IN_TX,        cpu/cycles-t/),
        ID(TRANSACTION_START,   cpu/tx-start/),
        ID(ELISION_START,       cpu/el-start/),
        ID(CYCLES_IN_TX_CP,     cpu/cycles-ct/),

};

Ok, guess I understood now, all the events above are transaction events, so if one of them is present, then, yes, this is a transaction run, and we don't need to look at the 'transaction_run' variable to update the shadow stats, got it right?

I.e. we _never_ needed to look at 'transaction_id', just noticing that ps->id is not zero, ok.

perf stat: Remove transaction_run from shadow update/print code

It's no longer needed, because we use nameid to recognize transaction events.

Keeping it only in stat code to initialize transaction events.

I.e. struct perf_stat::id, accessible via evsel->priv, will be only set for transaction related events.

PATCH v2 9/9 perf stat: Move shadow stat counters into separate object

In reply to Jiri Olsa

Separating shadow counters code into separate object as a cleanup, but mainly for upcomming changes, so could use it from script command context.

hi,
sending cleanup/move of shadow counters. I need it for my other changes of stat scripting, but I think it can stand alone as a cleanup.
v2 changes:
- move evsel id into 'struct perf_stat'
and change the id functions namespace

Thanks, applied.

arghh.. sry, I remember running tests :-\ really ;-) it's the -d default events that do not set evsel->name
