It seems that the SPARC processor and a "standard" interrupt controller
supports only 15 external interrupts (BSP_INTERRUPT_VECTOR_COUNT should
be 15 in this case) and some systems have an interrupt controller which
supports an extended interrupt which multiplex additional 16 interrupts
to a standard interrupt (BSP_INTERRUPT_VECTOR_COUNT should be 31 in this
case). Is this correct?
Actually, this doesn't fit with:
/* Initialize interrupts */
void BSP_shared_interrupt_init(void)
{
rtems_vector_number vector;
rtems_isr_entry previous_isr;
int i;
for (i=0; i <= BSP_INTERRUPT_VECTOR_MAX_STD; i++) {
#if defined(LEON3) && (defined(RTEMS_SMP) || defined(RTEMS_MULTIPROCESSING))
/* Don't install IRQ handler on IPI interrupt */
if (i == LEON3_mp_irq)
continue;
#endif
vector = SPARC_ASYNCHRONOUS_TRAP(i) + 0x10;
rtems_interrupt_catch(bsp_isr_handler, vector, &previous_isr);
}
/* Initalize interrupt support */
bsp_interrupt_initialize();
}
Can external interrupts end up in this trap:
SPARC_ASYNCHRONOUS_TRAP(0x10)? In start.S we have:
BAD_TRAP; ! 10 undefined
/*
* ERC32 defined traps
*/
BAD_TRAP; ! 11 masked errors
