Microsoft Releases Device Driver Code to the Linux Community

Peter Galli — Mon, 20 Jul 2009 16:48:00 GMT

In what many may see as a surprising move, Microsoft today released 20,000 lines of device driver code to the Linux community under the popular General Public Licence v2.

The code includes three Linux device drivers, and has been submitted to the Linux kernel community for inclusion in the Linux tree.

The drivers will be available to both the Linux community and customers, and will enhance the performance of the Linux operating system when virtualized on Windows Server 2008 Hyper-V or Windows Server 2008 R2 Hyper-V.

In an article posted to Microsoft's PressPass site, Tom Hanrahan, director of Microsoft's Open Source Technology Center, notes that this is a significant milestone because it's the first time the company has released code directly to the Linux community. "Additionally significant is that we are releasing the code under the GPLv2 license, which is the Linux community's preferred license," he said.

In the same article, Sam Ramji, senior director of Platform Strategy at Microsoft, points out that Microsoft communities and open source communities are growing together, which is ultimately of benefit to customers. An example of this is the Linux community, which has built a platform used by many customers. "So our strategy is to enhance interoperability between the Windows platform and many open source technologies, which includes Linux, to provide the choices our customers are asking for," he said.

Ramji also alluded to the fact that people are often surprised when they hear how much open source community and development work is happening across Microsoft, which is largely due to the fact that these collaborations focus more on getting the work done and engaging with the various communities on a one-to-one basis and less about promoting them.

One example of how Microsoft participates with, and contributes to, open source is its relationship with the PHP Community. The company's involvement includes contributing to the PHP Engine, optimizing PHP 5.3 to perform strongly on Windows, and working to improve the performance of numerous PHP applications on Windows. Then there is the ongoing participation in various Apache Software Foundation projects, such as Hadoop, Stonehenge and QPID.

"In short, we're focused on building sustainable business strategies for open source at Microsoft ... we see open source playing into three key areas, one of which is the use of 'inbound' open source and the open source development model to make our software development processes more efficient."

"Good examples of this include what we did recently with jQuery in Visual Studio 2008, the implementation of OpenPegasus connectors and adaptors into System Center Operations Manager, and work that the Microsoft High Performance Computing team did with the Argonne National Lab (ANL) to source its MPICH2 implementation, which is a portable implementation of the Message Passing Interface (MPI) used in cluster computing and super computers," Ramji said.

We'll be posting a number of other articles on the release of the device driver code to the Linux community over the week, several of which will be penned by Hank Janssen from Microsoft's Open Source Technology Center, so look out for those.

Tom Hanrahan: Director of Linux Interoperability

Sam Ramji — Fri, 08 Jun 2007 19:34:00 GMT

Most of Port 25’s readers are aware of my commitment to interoperability between Microsoft and Linux, as exemplified in the OSSL’s work on IPsec and now the three-sided virtualization, identity, and systems management work with Novell.

I’m proud to announce a leader at Microsoft who has the sole purpose of bringing Windows and Linux technologies together: Tom Hanrahan.

Tom will join as the Director of Linux Interoperability, and will head our Linux/Windows interoperability work, including leadership of the Microsoft/Novell Interoperability Lab. This development lab will undertake much of the engineering work involved in the multi-year technical partnership. Among other things, Tom has much to teach us on “developing in the open” – how to work in a transparent way with a broad engineering community.
Tom brings 30 years of engineering, management and community development experience to this effort – and the larger Microsoft community. Prior to joining Microsoft, Tom was the Director of Engineering at the Linux Foundation where he was responsible for managing a variety of technical initiatives. Earlier in his career, Tom led IBM’s Linux Technology Center in Portland, and spent 11 years at Sequent Computer Systems in the early days of SMP (symmetric multiprocessing).

It is excellent to have Tom on board, and he is already making an impact. His outstanding history of Linux engineering will greatly contribute to our focus on interoperability. You can also expect to see some of Tom’s work (and thoughts) show up on Port 25.

Please join me in welcoming Tom Hanrahan.
