Genode OS Framework release 13.08 | 2013-08-15
##############################################
| We celebrate our 5th anniversary with the addition of three major features:
| Qt5 on all kernels, profound multi-processor support on the NOVA and
| Fiasco.OC kernels, and light-weight tracing of inter-process communication.
The availability of Qt has always been one of the features that made our
framework attractive to the microkernel community. We have closely followed
the development of Qt5 and greatly appreciate the direction the Qt developers
are heading to. Now that Qt5 has reached a stable state, the time is right for
Genode to make the switch from Qt4 to Qt5. With the fresh port of Qt version
5.1 to Genode, Qt becomes available on the entirety of kernels supported by the
framework.
Component-based systems use to pose the difficulty of getting a holistic view
on the system. The more complex the system scenarios become, the more
inter-component communication takes place. Finding performance bottlenecks in
such kinds of de-componentized systems tends to be much more challenging than
in the world of monolithic systems. To overcome this challenge, the new
version comes with tracing support deeply built into the framework. This
facility is able to capture the interactions of Genode components between each
other in a light-weight fashion with almost no side effects.
As the third major addition, version 13.08 comes with substantial support for
multi-processor systems, in particular for using Genode with the NOVA kernel.
Within the NOVA developer community, this controversial topic has been
discussed for several years. It seemed like NOVA's multi-processor model was
inherently contradicting with the design of the Genode API. However, we have
finally found a fairly elegant solution that makes multiple CPUs seamlessly
available for Genode users on NOVA.
Besides these highlights, the release comes with new SATA 3.0 and
power-management drivers for the Samsung Exynos-5 SoC, updates the Fiasco.OC
kernel and L4Linux, and introduces measures for verifying the integrity of
downloaded 3rd-party source codes.
Those and many more topics are presented in detail in the
