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":
|
|
|
|
[https://genode.org]
|
|
|
|
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:
