Namespaces
	IOAPIC
	Abstraction of the I/O APIC that is used for management of external interrupts.The I/O APIC's Core component is the IO-redirection table. This table is used to configure a flexible mapping between the interrupt number and the external interruption. Entries within this table have a width of 64 bit. For convenience, the union IOAPIC::RedirectionTableEntry should be used for modifying these tables (see ioapic_registers.h for details).

Functions
void	IOAPIC::init ()
	Initializes the I/O APIC. More...
void	IOAPIC::config (uint8_t slot, Core::Interrupt::Vector vector, TriggerMode trigger_mode=TriggerMode::EDGE, Polarity polarity=Polarity::HIGH)
	Creates a mapping between an interrupt vector and an external interrupt. More...
void	IOAPIC::allow (uint8_t slot)
	Enables the redirection of particular external interrupts to the CPU(s). More...
void	IOAPIC::forbid (uint8_t slot)
	Selectively masks external interrupts by slot number. More...
bool	IOAPIC::status (uint8_t slot)
	Check whether an external interrupt source is masked. More...
