Kernel Devs Publish Position Statement on Linux Kernel Modules

We, the undersigned Linux kernel developers, consider any closed-source Linux kernel module or driver to be harmful and undesirable. We have repeatedly found them to be detrimental to Linux users, businesses, and the greater Linux ecosystem. Such modules negate the openness, stability, flexibility, and maintainability of the Linux development model and shut their users off from the expertise of the Linux community. Vendors that provide closed-source kernel modules force their customers to give up key Linux advantages or choose new vendors. Therefore, in order to take full advantage of the cost savings and shared support benefits open source has to offer, we urge vendors to adopt a policy of supporting their customers on Linux with open-source kernel code.

The Interactive Linux Kernel Map

IconThe Linux kernel is one of most complex open source projects. Even though there are a lot of books on the Linux kernel, it is still a difficult subject to comprehend. The Interactive Linux kernel map gives you a top-down view of the kernel. You can see the most important layers, functionalities, modules, functions, and calls. Each function on the map is a link to its source code. The map is interactive. You can zoom in and drag around to see details.

The DVD demonstrates how to port Linux into a Field Programmable Gate Array (FPGA) design using the 32-bit Xilinx MicroBlaze processor. It also highlights the benefits and tradeoffs when using the Memory Management Unit (MMU) in the MicroBlaze processor. The MMU enables designers to use commercial-grade operating systems when implementing their embedded designs with Xilinx FPGAs. The MicroBlaze Processor Linux Starter Kit includes the Linux for MicroBlaze Processor DVD, the Xilinx Embedded Development Kit - Spar

AMD's New Card Supports Linux From the Get-Go

Michael writes "Back in September AMD had announced a new ATI Linux driver as well as opening up their GPU specifications, and today they have taken an additional step to better support the Linux OS. With the just-announced Radeon HD 4850 RV770 they have provided same-day Linux support, and the Linux driver is now shipping alongside the Windows driver on their product CDs. In addition, they are encouraging their AIB partners to showcase Tux on the product packaging as a sign of Linux support. Last but certainly not least, AMD is committed from top-to-bottom product support on Linux and they will be introducing high-end features in their Linux driver such as MultiGPU CrossFire technology. Phoronix has a run-down on AMD's evolutionary leap in Linux support along with information on the open-source support for the RV770 GPU.

Linux kernel developers: Say no to closed-source modules

More than 135 Linux kernel developers have signed a document in protest of vendors that create closed-source code modules for the kernel, calling the practice "harmful and undesirable." The developers' statement stressed that they are speaking for themselves, and not any of their employers. Although the issue of proprietary kernel modules is not new, the matter recently came to a head, according to the developers. "We have just been receiving a constant stream of questions from companies asking how the Linux kernel developers feel about closed-source modules over the past year or so," reads an accompanying FAQ page.

Windows-Linux Integration

"The use of Linux is no longer the sole preserve of IT administrators and tech-savvy computer users. Linux can now easily be incorporated into your environment without even having to go through the hassle of re-partitioning a disk. My previous article on VMWare illustrates that Linux is now pretty much a tool for everyone to use. However, one argument often made against the use of Linux is the difficulty of managing it. For instance, can you easily store and retrieve files on a Linux machine? Also, what about the problem of just interacting with and running the Linux machine? Isn't keeping up to date with Linux security patches a big problem? These are all good questions that I answer in the remainder of this article.

Embedded Linux gets maintainers and a mailing list

A new mailing list, linux-embedded@vger.kernel.org has been created to discuss kernel issues that are embedded-specific. In addition, Paul Gortmaker and David Woodhouse have stepped up as the official kernel embedded maintainers. In that role, they will try to ensure that embedded concerns are kept firmly in mind as kernel features are added. Both of these ideas came more or less directly out of Andrew Morton's Embedded Linux Conference keynote and the questions afterward.
