The NIC router used to generate reports triggered by IP config changes or link state changes synchonously, i.e., inline with the activation context that caused the change. This has two disadvantages. First, it can lead to an excessive number of report updates in situations with quick bursts of triggering changes. In such situations it is preferable to collect the changes and reflect them with only one final report update. Second, synchronous reporting may happen while the router is in a state that leads to an incorrect report (e.g. during reconfiguration). To prevent this from happening, the router so far explicitely switched off reporting when entering incoherent states and back on when leaving them. However, this solution is error-prone as the exclusion windows must be maintained manually. Both issues can be solved by not directly generating a report when necessary but instead submitting a signal and letting the signal handler do the work in a dedicated activation context. Ref #4462 |

Genode source-code repositories
===============================
This directory contains the source-code repositories of the Genode OS
Framework. Each sub directory has the same principle layout as described in the
build-system manual:
:Build-system manual:
[https://genode.org/documentation/developer-resources/build_system]
The build system uses a configurable selection of those reposities to obtain
the source codes for the build process. The repositories are not independent
but build upon of each other:
:'base':
This directory contains the source-code repository of the fundamental
frameworks and interfaces of Genode. Furthermore, it contains the generic
parts of core.
:'base-<platform>':
These directories contain platform-specific source-code repositories
complementing the 'base' repository. The following platforms are supported:
:'hw':
The hw platform hosts Genode on a custom microkernel specifically
developed for Genode. The name "hw" denotes that Genode is executed on
bare hardware without a 3rd-party kernel underneath.
:'linux':
Linux kernel (both x86_32 and x86_64)
:'nova':
NOVA hypervisor ([https://hypervisor.org])
:'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.
:'okl4':
OKL4 kernel (x86_32 and ARM) developed at Open-Kernel-Labs.
:'pistachio':
L4ka::Pistachio kernel developed at University of Karlsruhe.
:'fiasco':
L4/Fiasco kernel developed at University of Technology Dresden.
:'sel4':
seL4 microkernel ([https://sel4.systems/])
:'os':
This directory contains the non-base OS components such as the init
component, 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.
:'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, freetype, ncurses, and Mesa.
:'dde_linux':
This source-code repository contains the device driver environment for
executing Linux subsystems as Genode components.
:'dde_ipxe':
This source-code repository contains the device-driver environment for
executing network drivers of the iPXE project.
:'dde_bsd':
This source-code repository contains the device-driver environment for
drivers of the OpenBSD operating system.
:'dde_rump':
This source-code repository contains the port of rump kernels, which are
used to execute subsystems of the NetBSD kernel as user level processes.
The repository contains a server that uses a rump kernel to provide
various NetBSD file systems to Genode.
:'pc':
This source-code repository hosts device drivers that are specific for PC
platforms. It depends on the 'dde_linux' repository.
:'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.
:'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'.
