Include dependency graph for lapic.h:

Namespaces
namespace	LAPIC
	Abstracts the local APIC (which is integrated into every CPU core)

namespace	LAPIC::IPI
	Inter-Processor Interrupts.

namespace	LAPIC::Timer
	Local Timer (for each LAPIC / CPU)

Functions
void	LAPIC::init (uint8_t logical_id)
	Initialized the local APIC of the calling CPU core and sets the logical LAPIC ID in the LDR register.

void	LAPIC::endOfInterrupt ()
	Signalize EOI (End of interrupt)

uint8_t	LAPIC::getID ()
	Get the ID of the current core's LAPIC.

uint8_t	LAPIC::getLogicalID ()
	Get the Logical ID of the current core's LAPIC.

void	LAPIC::setLogicalID (uint8_t id)
	Set the Logical ID of the current core's LAPIC.

uint8_t	LAPIC::getVersion ()
	Get version number of local APIC.

bool	LAPIC::IPI::isDelivered ()
	Check if the previously sent IPI has reached its destination.

void	LAPIC::IPI::send (uint8_t destination, uint8_t vector)
	Send an Inter-Processor Interrupt (IPI)

void	LAPIC::IPI::sendGroup (uint8_t logical_destination, uint8_t vector)
	Send an Inter-Processor Interrupt (IPI) to a group of processors.

void	LAPIC::IPI::sendAll (uint8_t vector)
	Send an Inter-Processor Interrupt (IPI) to all processors (including self)

void	LAPIC::IPI::sendOthers (uint8_t vector)
	Send an Inter-Processor Interrupt (IPI) to all other processors (all but self)

void	LAPIC::IPI::sendInit (bool assert=true)
	Send an INIT request IPI to all other processors.

void	LAPIC::IPI::sendStartup (uint8_t vector)
	Send an Startup IPI to all other processors.

uint32_t	LAPIC::Timer::ticks (void)
	Determines the LAPIC timer frequency.

void	LAPIC::Timer::set (uint32_t counter, uint8_t divide, uint8_t vector, bool periodic, bool masked=false)
	Set the LAPIC timer.

void	LAPIC::Timer::setMasked (bool masked)
	Set the LAPIC-timer interrupt mask.
