#1: Question about interrupts

Posted on 2011-08-01 14:18:58 by manish honap

Interrupt gates are set in linux as

set_intr_gate(i, interrupt[i-FIRST_EXTERNAL_VECTOR]);
^
but the 'interrupt' is declared as

extern void (*__initconst interrupt[NR_VECTORS-FIRST_EXTERNAL_VECTOR])(void);

can anyone possibly tell when are these enteries filled with valid pointers ???
