Developers must not rely on the absence or characteristics of any features or instructions marked “re-

served” or “undefined.” Improper use of reserved or undefined features or instructions may cause unpre-

these features or instructions for future definition and shall have no responsibility whatsoever for conflicts

or incompatibilities arising from their unauthorized use.

The Intel® 64 architecture processors may contain design defects or errors known as errata. Current char-

Hyper-Threading Technology requires a computer system with an Intel ® processor supporting Hyper-

Threading Technology and an HT Technology enabled chipset, BIOS and operating system. Performance will

vary depending on the specific hardware and software you use. For more information, see http://www.in-

tel.com/technology/hyperthread/index.htm; including details on which processors support HT Technology.

Intel® Virtualization Technology requires a computer system with an enabled Intel ® processor, BIOS, virtual

machine monitor (VMM) and for some uses, certain platform software enabled for it. Functionality, perfor-

mance or other benefits will vary depending on hardware and software configurations. Intel ® Virtualization

Technology-enabled BIOS and VMM applications are currently in development.

64-bit computing on Intel architecture requires a computer system with a processor, chipset, BIOS, oper-

ating system, device drivers and applications enabled for Intel ® 64 architecture. Processors will not operate

(including 32-bit operation) without an Intel ® 64 architecture-enabled BIOS. Performance will vary de-

pending on your hardware and software configurations. Consult with your system vendor for more infor-

mation.

INTRODUCTION

CHAPTER 1

INTRODUCTION

1.1 INTRODUCTION

The xAPIC architecture provided a key mechanism for interrupt delivery in many

generations of Intel processors and platforms across different market segments. This

document describes the x2APIC architecture which is extended from the xAPIC archi-

tecture (the latter was first implemented on Intel® Pentium® 4 Processors, and

extended the APIC architecture implemented on Pentium and P6 processors). Exten-

sions to the xAPIC architecture are intended primarily to increase processor addres-

sability. The x2APIC architecture provides backward compatibility to the xAPIC

architecture and forward extendability for future Intel platform innovations. Specifi-

cally, x2APIC

•Retains all key elements of compatibility to the xAPIC architecture:

— delivery modes,

— interrupt and processor priorities,

— interrupt sources,

— interrupt destination types;

•Provides extensions to scale processor addressability for both the logical and

physical destination modes;

•Adds new features to enhance performance of interrupt delivery;

•Reduces complexity of logical destination mode interrupt delivery on link based

architectures.

1.2 IMPACTED PLATFORM COMPONENTS

x2APIC is architected to extend from the xAPIC architecture while minimizing the

impact on platform components. Specifically, support for the x2APIC architecture can

be implemented in the local APIC unit. All existing PCI/MSI capable devices and

IOxAPIC unit should work with the x2APIC extensions defined in this document. The

x2APIC architecture also provides flexibility to cope with the underlying fabrics that

connect the PCI devices, IOxAPICs and Local APIC units.

The extensions provided in this specification translate into modifications to:

•the local APIC unit,

•the underlying fabrics connecting Message Signaled Interrupts (MSI) capable PCI

devices to local xAPICs,

•the underlying fabrics connecting the IOxAPICs to the local APIC units.
