__eoi_ioapic_pin

Name:IO-APIC versions below 0x20 don't support EOI register

Proto:static void __eoi_ioapic_pin(int apic, int pin, int vector)

Type:void

Parameter:

Type	Parameter	Name
int	apic
int	pin
int	vector

512

If mpc_ioapic_ver(apic) >= 0x20 Then

513

io_apic_eoi(apic, vector)

514

Else

517

entry = entry1 = __ioapic_read_entry(apic, pin)

522

0: enabled, 1: disabled = IOAPIC_MASKED

523

0: edge, 1: level = IOAPIC_EDGE

525

When we write a new IO APIC routing entry, we need to write the high* word first! If the mask bit in the low word is clear, we will enable* the interrupt, and we need to make sure the entry is fully populated* before that happens.
