AMD has announced the broad availability of its I/O virtualisation technology specification.
The technology is available through royalty-free licences that AMD hopes will encourage its widespread adoption by hardware and software developers. The technologies under development by AMD will be built directly into a computer’s I/O bridges.

AMD says its I/O virtualisation technology is designed to extend the benefits of CPU-assisted virtualisation by addressing the performance bottlenecks and security issues that can be encountered when virtualising I/O devices in x86-based servers, desktops and notebook computers.
The company will share its specification publicly, making it available through licences across the hardware and software development community. AMD’s CPU virtualisation technology, formerly referred to by the code name Pacifica, delivers CPU efficiencies to traditional software only-based virtualisation approaches.
AMD is providing mechanisms to support virtualisation software in managing, partitioning and securing I/O devices, which the company says will result in improved performance and less implementation complexity in providing I/O in virtual environments.
The company’s I/O virtualisation technology should be supported by all AMD processors in mid-2006, and is also anticipated to be implemented in chipsets and core logic designed for AMD64-based platforms in 2006.
