pok_ret_t pok_bsp_irq_register	(	uint8_t	irq,
		void(*)(void)	handler
	)

Definition at line 42 of file bsp.c.

}

void* pok_bsp_mem_alloc

(

size_t

size

)

Used for partition allocation. For SPARC support, all partitions are aligned on page size and all partition sizes have to be less than page size.

See also:

SPARC_PAGE_SIZE

Allocate data. At this time, the pok_pm_sbrk function only increment size each time we allocate memory and was not designed to free previously allocated memory.

Definition at line 34 of file bsp.c.

{
  char *res;

  res = (char *)(((unsigned int)heap_end + 4095) & ~4095);
  heap_end = res + sz;
  return res;
}

pok_ret_t pok_bsp_time_init

(

)

Initialize the timer, register the ISR and unmask the interrupt.

See also:

unmask_irq(irq_nbr)

Init time. freq is the frequency of the oscillator.

Definition at line 87 of file timer.c.

{
  time_inter = (BUS_FREQ * FREQ_DIV) / POK_TIMER_FREQUENCY;
  time_last = get_ppc_tb ();
  pok_arch_set_decr();

  return (POK_ERRNO_OK);
}
