I've never heard about IO-APIC before, so I just did a Google search.
The articles I found say that it's an Intel thing, and, since I have an
AMD processor w/ ASUS motherboard, it's unlikely it'll work, right?
Even so, it sounds interesting. But does it apply to single-processor
systems, even if they're using they're using Intel processors and Intel
chipsets? The articles say this is for SMP systems ...
Hi Jenny,
IOAPIC is not "an Intel thing", nor exclusive to SMP. Here is a small
section from dmesg on my nVidia nForce 4 chipset, single Athlon 64 system:
ACPI: Using IOAPIC for interrupt routing
PCI: Using ACPI for IRQ routing
ACPI: PCI Interrupt Link [APCS] enabled at IRQ 23
ACPI: PCI interrupt 0000:00:01.1[A] -> GSI 23 (level, low) -> IRQ 177
ACPI: PCI Interrupt Link [APCF] enabled at IRQ 22
ACPI: PCI interrupt 0000:00:02.0[A] -> GSI 22 (level, low) -> IRQ 185
ACPI: PCI Interrupt Link [APCL] enabled at IRQ 21
ACPI: PCI interrupt 0000:00:02.1[B] -> GSI 21 (level, low) -> IRQ 193
ACPI: PCI Interrupt Link [APCJ] enabled at IRQ 20
ACPI: PCI interrupt 0000:00:04.0[A] -> GSI 20 (level, low) -> IRQ 201

Richard
