The destructor of the Area object uses invalid caps which results in a wanted abort of the process on nova. This is mainly the case in forked process in noux. |

================================= Genode Operating System Framework ================================= This is the source tree of the reference implementation of the Genode OS architecture. For a general overview about the architecture, please refer to the project's official website: :Official project website for the Genode OS Framework: [http://genode.org/documentation/general-overview] The current implementation can be compiled for 8 different kernels: Linux, L4ka::Pistachio, L4/Fiasco, OKL4, NOVA, Fiasco.OC, Codezero, and a custom kernel for running Genode directly on ARM-based hardware. 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 the use of each of the kernels listed above 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. Directory overview ################## The Genode source tree is composed of the following subdirectories: :'doc': This directory contains general documentation. Please consider the following document for a quick guide to get started with the framework: ! doc/getting_started.txt If you are curious about the ready-to-use components that come with the framework, please review the components overview: ! doc/components.txt :'base': This directory contains the source-code repository of the fundamental frameworks and interfaces of Genode. Furthermore, it contains the generic parts of core. :'os': This directory contains the non-base OS components such as the init process, device drivers, and basic system services. :'demo': This directory contains the source-code repository of various services and applications that we use for demonstration purposes. For example, a graphical application launcher called Launchpad and the Scout tutorial browser. :'base-<platform>': These directories contain platform-specific source-code repositories complementing the 'base' repository. The following platforms are supported: :'linux': Linux kernel (both x86_32 and x86_64) :'nova': NOVA hypervisor developed at University of Technology Dresden See [http://genode.org/documentation/platforms/nova] :'foc': Fiasco.OC is a modernized version of the Fiasco microkernel with a completely revised kernel interface fostering capability-based security. It is not compatible with L4/Fiasco. See [http://genode.org/documentation/platforms/foc] :'hw': The hw platform allows the execution of Genode on bare ARM hardware without the need for a separate kernel. The kernel functionality is included in core. See [http://genode.org/documentation/platforms/hw] :'okl4': OKL4 kernel (x86_32 and ARM) developed at Open-Kernel-Labs. See [http://genode.org/documentation/platforms/okl4] :'pistachio': L4ka::Pistachio kernel developed at University of Karlsruhe. See [http://genode.org/documentation/platforms/pistachio] :'fiasco': L4/Fiasco kernel developed at University of Technology Dresden. See [http://genode.org/documentation/platforms/fiasco] :'codezero': Codezero microkernel developed by B-Labs See [http://genode.org/documentation/platforms/codezero] :'host': Pseudo platform documenting the interface between the generic and platform-specific parts of the base framework. This is not a functional base platform. :'tool': Source-code management tools and scripts. Please refer to the README file contained in the directory. :'hello_tutorial': Tutorial for creating a simple client-server scenario with Genode. This repository includes documentation and the complete source code. :'libports': This source-code repository contains ports of popular open-source libraries to Genode, most importantly the C library. The repository contains no upstream source code but means to download the code and adapt it to Genode. For instructions about how to use this mechanism, please consult the README file at the top level of the repository. Among the 3rd-party libraries are Qt5, libSDL, freetype, Python, ncurses, Mesa, and libav. :'dde_linux': This source-code repository contains the device driver environment for executing Linux device drivers natively on Genode. Currently, this repository hosts the USB stack. :'linux_drivers': Deprecated version of the Linux device driver environment featuring audio drivers and the Intel GEM driver. This repository is in a transitionary phase. Its functionality will be incorporated into 'dde_linux'. :'dde_ipxe': This source-code repository contains the device-driver environment for executing drivers of the iPXE project. :'dde_oss': This source-code repository contains the device-driver environment for the audio drivers of the Open Sound System (OSS). :'qt4': This source-code repository contains the Genode version of Qt4 framework. Please find more information about using Qt4 with Genode in the repository's 'README' file. Please note that the Qt4 support is deprecated. Use Qt5 as contained in 'libports' instead. :'ports': This source-code repository hosts ports of 3rd-party applications to Genode. The repository does not contain upstream source code but provides a mechanism for downloading the official source distributions and adapt them to the Genode environment. The used mechanism is roughly the same as used for the 'libports' repository. Please consult 'libports/README' for further information. :'ports-<platform>': These platform-specific source-code repositories contain software that capitalizes special features of the respective kernel platform. For the Fiasco.OC platform, 'ports-foc' hosts a port of the L4Linux kernel. For further information, please refer to the README file at the top level of the respective repository. :'gems': This source-code repository contains Genode applications that use both native Genode interfaces as well as features of other high-level repositories, in particular shared libraries provided by 'libports'.
