The assignment of affinities consists of two parts, the definition
of the affinity space dimensions as used for the init process, and
the association sub systems with affinity locations (relative to the
affinity space). The affinity space is configured as a sub node of the
config node. For example, the following declaration describes an
affinity space of 4x2:
<config>
...
<affinity_space width="4" height="2" />
...
</config>
Subsystems can be constrained to parts of the affinity space using
the '<affinity>' sub node of a '<start>' entry:
<config>
...
<start name="loader">
<affinity xpos="0" ypos="1" width="2" height="1" />
...
</start>
...
</config>

This is the example operating system based on the Genode OS framework: :_Init_: is the first real process in the system. The provided implementation uses a very simple XML parser to read its configuration files. :_Drivers_: The example OS has basic drivers for frame buffer, mouse and keyboard input, the PCI bus, the real-time clock, and system-specific timers. :_Server_: The only server in the example OS is Nitpicker, a minimal-complexity GUI server. :_Test_: are also part of the example OS. You may have a look at the fork bomb as a simple system stress test. :_Ldso_: is the dynamic linker used for loading executables that are linked against shared libraries. :_Lib_: contains libraries used by the components of the OS repository, in particular the device-driver kit, the alarm framework, and support for dynamic linking.
