Genode OS Framework release 16.08

Genode 16.08 brings lots of improvements ranging from base-platform support over networking and virtualization to a new tool for statistical profiling. We are proud to announce that we support seL4 as base platform for dynamic and interactive scenarios on x86. The new version enables users of seL4 to compose dynamic operating systems from a plethora of ready-to-use Genode components. Further, the Muen developers contribute their efforts in running unmodified guest operating systems on top their separation kernel with a port of VirtualBox 4. As we consider VirtualBox as key feature of Genode, this release includes a first experimental version of VirtualBox 5 on top of the NOVA kernel. Another highlight of the new version is a virtual networking component for routing and NAT accompanied by the ability to use the TOR network.... read more

Genode OS Framework release 16.05

The central aspect of the current release is the fundamental renovation of our base API. The API gradually evolved over the years since 2006 while we gained a wealth of experience with a wide range of usage scenarios and their requirements. We eventually realized that we need fundamental changes to greatly increase robustness and flexibility, and those changes will break backwards compatibility in many places. Therefore, this release brings new API functions reflecting our current knowledge about how a secure C++ OS framework should look like and, on the other hand, deprecates a wide range of interfaces that will be removed in future versions.... read more

Genode OS Framework release 15.05

With Genode 15.05, our base-hw kernel, which enables the execution of Genode without a third-party microkernel and originally supported the ARM architecture only, has become able to run on the 64-bit x86 architecture. Also, base-hw received support for kernel-protected capabilities and the scheduler got much more flexible. Beside the improvements of our custom kernel, we also introduce preliminary support to run simple system scenarios on top of the seL4 microkernel. With seL4, there is now the prospect of running Genode on top of a formally verified kernel.... read more

Genode OS Framework release 15.02

Our plans for 2015 comprise the consolidation and cultivation of the existing feature set of Genode rather than the conquering of new grounds. Along these lines, our fresh release introduces a highly modular tool kit for automated testing and brings plenty of stability and performance improvements, e.g., for VirtualBox on NOVA. Nevertheless, we added one prominent feature to Genode 15.02, which is support for virtualization on ARM with our custom base-hw kernel.... read more

Genode OS Framework release 14.11

With the current release, we enable support for wireless networking including WiFi protected access (WPA) in Genode. The supported hardware is currently limited to Intel wireless chipsets, i.e., iwl6xxx. The second major improvement is a new scheduler for our custom HW kernel. The new scheduler allows to trade CPU resources among Genode subsystems, similarly to how RAM is managed in Genode.

Other highlights of Genode 14.11 are a new dynamic linker implemented from scratch with a complexity of less than 20% of the old ported one, an upgrade of VirtualBox to version 4.3.16 along with extensive stability improvements, networking support for Raspberry Pi, and new GUI components.... read more

Genode OS Framework release 13.02

The February 2013 release follows the tradition to focus on platform support at the beginning of a year. So, we improved the support for the NOVA microhypervisor (dynamic workloads, IOMMU, x86 virtualization) and extended the range of supported ARM SOCs (i.MX53, Exynos 5250). Additionally, several aspects of the framework were revised and conditioned for future challenges (synchronization primitives, low-latency audio, fault detection).... read more

Genode OS Framework release 12.11

The Genode developers are celebrating the self-hosting of their genuine operating system environment with a fresh release. On the bill are also OSS-based sound drivers, extended support for the TI OMAP4 and Freescale i.MX SoCs, and numerous stability and performance improvements concerning the underlying kernel platforms.

The most notable improvement from the perspective of a Genode developer is the ability to build Genode within the Genode environment leaving aside any virtualization. Therefore, we extended our UNIX-runtime environment named Noux to fit the requirements of a lot of tools involved in the build process (e.g., GCC, binutils, bash, and findutils). Furthermore, we extensively improved the support for OMAP4 SoC used in the famous Pandaboard. An accompanying article telling the adventure can be found here read more

Genode OS Framework release 12.08

On its 4th anniversary Genode brings enhanced platform support for ARM and the NOVA microhypervisor. Also, Genode is now able to run directly on ARM platforms without the need for an underlying kernel.

The current release introduces the new base-hw platform, which enables Genode to run directly on ARM Cortex-A9 platforms. The new hybrid kernel-core approach vastly reduces the complexity of the root of the process tree to about 13,000 lines of code with highly positive impact on security and robustness. Furthermore, the support for NOVA experienced an extensive improvement. Genode/NOVA now runs on x86 32bit and 64bit platforms, utilizes kernel capabilities for object-integrity protection, and centralizes kernel-resource allocation in core. Additionally, enhanced OMAP4 SoC support, VFAT and TAR file-system support, Noux runtime improvements and the port of the lighttp web server complete this release.... read more

Genode OS Framework release 12.05

Genode walks the road mapped for 2012 and brings a release packed with features, e.g., native execution of the tool chain (GCC, G++, Binutils), a new USB stack, and media replay capabilities.

The release follows our road map and introduces three major features. First, the Noux runtime is growing and thriving. It supports a growing number of unmodified GNU programs, most notably the Genode tool chain. Furthermore, we added support of stacked file systems and networking. Second, we fundamentally re-approach the challenge of device drivers and ported a new USB stack from Linux 3.2 to Genode. Finally, Genode 12.05 adds a native file-system session interface and first implementation of an in-memory file system. The new interface is already integrated in Noux and the C runtime.... read more

Genode OS Framework release 12.02

The current release marks the first step in our open development process. It brings fork support in Noux, ACPI support, and base framework improvements.

At the turn of the year 2011/12, we changed Genode's development process from a Genode Labs internally driven model to a completely open process. The new approach involves the community into more design, operational, and even strategic discussions. The first step was the issue-tracker migration from Sourceforge to GitHub. After that we migrated the source code from Genode-Labs-internal Mercurial repositories to a public Git repository also hosted on GitHub. From now on, reflects the current state of development of the official Genode repository and is accompanied by several public forks with feature branches of Genode developers on GitHub. Nonetheless, we will release quarterly on Sourceforge via Subversion and archive files in the future.... read more

Genode bug tracker moved to GitHub

The Genode project opens up its development process and, therefore, goes to GitHub for its code repository and issue tracker. We already migrated all issues to and are working on the code migration. Nevertheless, we plan to maintain the Sourceforge Subversion repository and file releases in the future.

Genode OS Framework release 11.11

Today, Genode Labs published the new version of the Genode OS framework packed with cool features: Vancouver VMM on Nova, Vi IMproved in our UNIX environment, L4Android on Fiasco.OC, native GDB support, and new platform drivers for ARM. Additionally, Genode brings its own GCC 4.6 based tool chain.

Virtualization support is a must in modern operating systems and Genode walked this path in the past with support for OKLinux and L4Linux. With the current release, we complete the plethora of virtualization levels in Genode by support for faithful virtualization using the Vancouver VMM on Nova, an Android-compatible version of L4Linux, and the Noux runtime environment for UNIX applications. Even on application level, the support for GDB-based debugging of Genode subsystems adds to this picture as kind of "application-level virtualization".... read more
