On the heels of their December release, the 13.02 release of the Genode multi-server microkernel OS framework continues to deliver major new features. Under the hood, there's support for the IOMMU, bringing safe bus master DMA to userspace drivers (overcoming one of the final advantages monolithic kernels had). They've also added full virtualization support, good enough to boot Linux as an application. In the cool department, they've added a new low latency audio interface that could very well pave the way for something akin to JACK, and right now provides a lightweight way for the system to beep at you in real time . A few more libraries have been ported (libssh, curl, iconv) in preparation for a port of git to the Noux native GNU runtime. There are also a bunch of other improvements to their NOVA microkernel, support for running on the Exynos 5250 and Freescale i.MX53, a new console multiplexer, improvements to the display server, simplification of the base libraries, and more. I'll be attempting to build it and give it a spin to see how well it works in practice sometime soon.

An anonymous reader wrote in with a story on OS News about the latest release of the Genode Microkernel OS Framework. Brought to you by the research labs at TU Dresden, Genode is based on the L4 microkernel and aims to provide a framework for writing multi-server operating systems (think the Hurd, but with even device drivers as userspace tasks). Until recently, the primary use of L4 seems to have been as a glorified Hypervisor for Linux, but now that's changing: the Genode example OS can build itself on itself: "Even though there is a large track record of individual programs and libraries ported to the environment, those programs used to be self-sustaining applications that require only little interaction with other programs. In contrast, the build system relies on many utilities working together using mechanisms such as files, pipes, output redirection, and execve. The Genode base system does not come with any of those mechanisms let alone the subtle semantics of the POSIX interface as expected by those utilities. Being true to microkernel principles, Genode's API has a far lower abstraction level and is much more rigid in scope." The detailed changelog has information on the huge architectural overhaul of this release. One thing this release features that Hurd still doesn't have: working sound support. For those unfamiliar with multi-server systems, the project has a brief conceptual overview document.
