C++ (Cpp) CPUID_TO_APICID Examples

Example #1

/*
 * Print various information about the SMP system hardware and setup.
 */
void
mp_announce(void)
{
	int     x;

	POSTCODE(MP_ANNOUNCE_POST);

	kprintf("DragonFly/MP: Multiprocessor motherboard\n");
	kprintf(" cpu0 (BSP): apic id: %2d\n", CPUID_TO_APICID(0));
	for (x = 1; x <= naps; ++x)
		kprintf(" cpu%d (AP):  apic id: %2d\n", x, CPUID_TO_APICID(x));

	if (!ioapic_enable)
		kprintf(" Warning: APIC I/O disabled\n");
}

Example #2

File: msi.c Project: kusumi/DragonFlyBSD

void
msi_map(int intr, uint64_t *addr, uint32_t *data, int cpuid)
{
	int vector, lapic_id;

	vector = IDT_OFFSET + intr;
	lapic_id = CPUID_TO_APICID(cpuid);

	*addr = MSI_X86_ADDR(lapic_id);
	*data = MSI_X86_DATA(vector);
