System Support

4.3 System Resources

This section describes the availability and basic control of major subsystems, otherwise known as
resource allocation or simply “system resources.” System resources are provided on a priority
basis through hardware interrupts and DMA requests and grants.

4.3.1 Interrupts

The microprocessor uses two types of hardware interrupts; maskable and nonmaskable. A
maskable interrupt can be enabled or disabled within the microprocessor by the use of the STI
and CLI instructions. A nonmaskable interrupt cannot be masked off within the microprocessor,
although it may be inhibited by hardware or software means external to the microprocessor.

Maskable Interrupts

The maskable interrupt is a hardware-generated signal used by peripheral functions within the
system to get the attention of the microprocessor. Peripheral functions produce a unique INTA-H
(PCI) or IRQ0-15 (ISA) signal that is routed to interrupt processing logic that asserts the
interrupt (INTR-) input to the microprocessor. The microprocessor halts execution to determine
the source of the interrupt and then services the peripheral as appropriate.

Most IRQs are routed through the I/O controller of the super I/O component, which provides the
serializing function. A serialized interrupt stream is then routed to the ICH component.

Interrupts may be processed in one of two modes (selectable through the F10 Setup utility):

■

8259 mode

■

APIC mode

These modes are described in the following subsections.
