Genode Operating System Framework
=================================This is the source code of Genode, which is a framework for creating component-based operating systems. It combines capability-based security, microkernel technology, sandboxed device drivers, and virtualization with a novel operating system architecture. For a general overview about the architecture, please refer to the project's official website:
:Website for the Genode OS Framework:
[https://genode.org/documentation/general-overview]
Genode-based operating systems can be compiled for a variety of kernels: Linux, L4ka::Pistachio, L4/Fiasco, OKL4, NOVA, Fiasco.OC, seL4, and a custom "hw" microkernel for running Genode without a 3rd-party kernel. Whereas the Linux version serves us as development vehicle and enables us to rapidly develop the generic parts of the system, the actual target platforms of the framework are microkernels. There is no "perfect" microkernel - and neither should there be one. If a microkernel pretended to be fit for all use cases, it wouldn't be "micro". Hence, all microkernels differ in terms of their respective features, complexity, and supported hardware architectures.
Genode allows for the use of each of the supported kernels with a rich set of device drivers, protocol stacks, libraries, and applications in a uniform way. For developers, the framework provides an easy way to target multiple different kernels instead of tying the development to a particular kernel technology. For kernel developers, Genode contributes advanced workloads, stress-testing their kernel, and enabling a variety of application use cases that would not be possible otherwise. For users and system integrators, it enables the choice of the kernel that fits best with the requirements at hand for the particular usage scenario.
Documentation #############
The primary documentation is the book "Genode Foundations", which is available on the front page of the Genode website:
:Download the book "Genode Foundations":
The book describes Genode in a holistic and comprehensive way. It equips you with a thorough understanding of the architecture, assists developers with the explanation of the development environment and system configuration, and provides a look under the hood of the framework. Furthermore, it contains the specification of the framework's programming interface.
The project has a quarterly release cycle. Each version is accompanied with detailed release documentation, which is available at the documentation section of the project website:
