Interrupts
This section describes the programming model of the high performance interrupt
architecture. Interrupts are managed by the processor and by one or more intelligent
external interrupt controllers or devices in the I/O subsystem.
shows just
one example of a high performance interrupt architecture subsystem; other topologies
are possible. The processor is responsible for queuing and masking interrupts, sending
and receiving inter-processor interrupt (IPI) messages, receiving interrupt messages
from external interrupt controller(s), and managing local interrupt sources. This
document describes the processor’s interrupt control mechanism only; for details on
external interrupt controllers or I/O devices refer to platform documentation.

a. Unlike the other Reserved IVT vectors, which may defined in future revisions of the architecture, vector
0x5800 is permanently reserved. Software may use this vector for any purpose, such as placing in this area
portions of other handlers that don't fit into their assigned vector.
