SUSE Linux, the international technology leader and solution provider in open source operating system software, and Advanced Micro Devices, Inc., global supplier of integrated circuits for the personal and networked computer and communications markets, announced today that SUSE will drive the Linux community’s work to port Linux to AMD’s new 64-bit architecture, x86-64. The X86-64 port of Linux will run new 64 bit applications as well as currently existing 32 bit ix86 Linux applications. The first versions of the development tools (GCC and binutils) have already been written by SUSE developer Jan Hubicka.

AMD released the specification of their new 64 bit architecture called x86-64 (CPU codename: Sledgehammer) last week. The release of the specification allows programmers to write code to run on the x86-64 architecture. AMD x86-64 technology is designed to enable platform suppliers, developers, and corporations to transition to 64-bit environments while continuing to have leading performance on the vast installed base of existing 32-bit applications.

Early participants in the discussions involving x86-64 include developers from AMD, SUSE CodeSourcery LLC, ACT and PGI. With the opening up of the specification, developers are now welcome to participate in the development and discussions. Details can be found on the x86-64 website at

Dirk Hohndel, CTO of SUSE Linux AG, said, “AMD’s action supports the open source community and certainly encourages code development. We’re looking forward to work together with AMD and the Linux Community on an open port of Linux to x86-64.

“It has been exciting and a great pleasure for AMD to begin working with Linux developers to help refine the x86-64 architecture,” said Fred Weber, AMD’s Vice President of Engineering. “AMD is about better ideas that meet the needs of the market and our customers. Together, with our friends in the open-source community, we can extend the benefits of today’s x86 architecture to meet the needs of tomorrow’s demanding applications.”

Mark Mitchell, President of CodeSourcery LLC, said, “We’re looking forward to working with SUSE on the Linux port. SUSE is a real leader in Linux technology, and CodeSourcery has a lot of tools experience. I think that together we’ll make x86-64 Linux a dynamite OS.”

A draft version of the System V ABI (Application Binary Interface) for x86-64 is available. The editors of the ABI are Mark Mitchell, CodeSourcery LLC, Jan Hubicka, SUSE Linux AG, and Andreas Jaeger, SUSE Linux AG.
