Genode OS Framework release 17.02 | 2017-02-28
##############################################
| By introducing application binary interfaces, version 17.02 cultivates
| the cross-kernel binary compatibility of components. Furthermore, the
| new version comes with a vastly improved VFS infrastructure, new input-event
| processing capabilities, and a dynamic component-composition engine.
On the long road towards binary compatibility of Genode components across OS
kernels as different as L4, NOVA, seL4, or Linux, we reached a breakthrough by
mid of 2016. It took us another six months to fully cultivate this unique
feature and to integrate it seamlessly into our development work flows. With
the current version, we have ultimately reached the point where one can move
entire system scenarios from one kernel to another in just a few seconds.
With the improved virtual file-system (VFS) infrastructure that comes with the
new version, such system scenarios can become more and more sophisticated.
Genode takes the meaning of _virtual_ file systems to an entirely new level.
Not only does Genode virtualize the physical location of files but each
component can have its own VFS whereby the supported file-system types are
provided by VFS plugins. Those plugins can go as far as providing a TCP/IP
stack as showcased by Genode's use of the Linux TCP/IP stack as VFS plugin.
The composition of subsystems out of Genode components is another highlight of
the current release. In each Genode-based system, the init component already
plays a central role as it bootstraps the initial system components. Thanks to
Genode's recursive system structure, init can easily be nested. With the
improvements of the new version, such a nested init becomes a dynamic
system-composition engine that responds to configuration updates and applies
changes to its subsystem in a differential way.
These and many more improvements are covered in full detail in the
