Re: Wrong number of CPUs detected on RPI3 and FreeBSD 13.1

After some debug I found that this routine is returning -1:

vi +50 /usr/src/sys/dev/psci/psci.h

/* Handler to let us call into the PSCI/SMCCC firmware */
extern psci_callfn_t psci_callfn;
static inline int
psci_call(register_t a, register_t b, register_t c, register_t d)
{

         return (psci_callfn(a, b, c, d, 0, 0, 0, 0, NULL));
}

/*
  * PSCI return codes.
  */
#define PSCI_RETVAL_SUCCESS             0
#define PSCI_RETVAL_NOT_SUPPORTED       -1
#define PSCI_RETVAL_INVALID_PARAMS      -2

Someone can give-me a hint about the function of psci_callfn ?

Thanks a lot
