PAPI_TOT_INS Problem in ARMv7

[aflorenzon]

Hello
I'm having trouble using the event "PAPI_TOT_INS" in ARMv7.

When I run "make fulltest", the following error occurs return:

Error in PAPI_add_event (PAPI_TOT_INS): Permission level does not permit operation


Can anyone help?

Thanks.

And the following behavior occurs when you run an application to find the total number of instructions:

Execution 1:
./my_program
out: PAPI_TOT_INS = 23339111815

Execution 2:
./my_program
out: PAPI_TOT_INS = 1831345992

Why?
-------------------------------------------------------------------------------------------------------------------
The code:
int main(int argc, char **argv){

int EventSet = PAPI_NULL;
unsigned long long valor = 0;
PAPI_library_init(PAPI_VER_CURRENT);
PAPI_create_eventset(&EventSet);
PAPI_add_event(EventSet, PAPI_TOT_INS);
PAPI_start(EventSet);
PAPI_reset(EventSet);

int *vetor;
vetor = (int*) malloc(sizeof(int)*N);

leEntrada(vetor);
par_impar(vetor);

PAPI_read(EventSet, &valor);
printf("PAPI_TOT_INS = %llu\n", valor);
PAPI_stop(EventSet, NULL);
return 0;
}

Can anyone help?

Thanks.
