Macro Definition Documentation

◆ APIC_TIMER_TICKS_FIXED_POINT_OFFSET

#define APIC_TIMER_TICKS_FIXED_POINT_OFFSET 32

APIC Timer Ticks Fixed Point Offset.

Used for fixed point arithmetic when returning the apic timer ticks per nanosecond.

Definition at line 176 of file apic.h.

◆ IOAPIC_REG_REDIRECTION

#define IOAPIC_REG_REDIRECTION	(	pin,
		high
	)	(0x10 + (pin) * 2 + (high))

Macro to get the redirection entry register for a specific pin.

This is used since a redirect entry is 64 bits (a qword/two dwords) and each register is 32 bits (a dword), so each pin uses two registers.

Parameters

pin	The pin number as in the gsi - the ioapics base gsi.
high	0 for the low dword, 1 for the high dword.

Returns: The register number.

Function Documentation

◆ apic_timer_one_shot()

void apic_timer_one_shot	(	interrupt_t	vector,
		uint32_t	ticks
	)

Configure the apic timer in one-shot mode.

Cnfigures the apic timer on the caller cpu to fire a single interrupt after the specified amount of ticks.

Parameters

vector	The interrupt vector to fire when the timer expires.
ticks	The amount of ticks to wait before firing the interrupt.

◆ apic_timer_ticks_per_ns()

uint64_t apic_timer_ticks_per_ns ( void )

Apic timer ticks per nanosecond.

Retrieves the ticks that occur every nanosecond in the apic timer on the caller cpu. Due to the fact that this amount of ticks is very small, most likely less then 1, we used fixed point arithmetic to store the result, the offset used for this is APIC_TIMER_TICKS_FIXED_POINT_OFFSET.

Returns: The number of ticks per nanosecond, stored using fixed point arithmetic.

		ioapic_delivery_mode_t	deliveryMode,
		ioapic_polarity_t	polarity,
		ioapic_trigger_mode_t	triggerMode,
		cpu_t *	cpu,
		bool	enable
	)

Set an IOAPIC redirection entry.

When an interrupt is triggered on the given GSI, the IOAPIC will use the redirection entry to determine how and where to send the interrupt.

Say we recieve a GSI 1 interrupt (this would usually be a interrupt from the first ps/2 port), and we have a redirection entry which sends it to vector 0x21 (we usually want to avoid using vectors 0x00-0x20 as those are reserved for exceptions) to the CPU with id 0, the IOAPIC will then send an interrupt to CPU 0 with vector 0x21.

Parameters

vector	The interrupt vector to set.
gsi	The GSI to set the redirection for.
deliveryMode	The delivery mode to use.
polarity	The polarity to use.
triggerMode	The trigger mode to use.
cpu	The target cpu to send the interrupt to.
enable	Whether to enable or disable the redirection.
