Genode OS Framework release 15.02 | 2015-01-27
|
||||||
|
##############################################
|
||||||
|
|
||||||
|
| Version 15.02 extends the base-hw kernel with ARM-virtualization support,
|
||||||
|
| introduces a highly modularized tool kit for automated testing, adds
|
||||||
|
| support for the USB Armory platform, and improves the performance and
|
||||||
|
| stability of VirtualBox on Genode/NOVA.
|
||||||
|
|
||||||
|
Most of the previous releases were motivated by our desire for features that
|
||||||
|
we deemed as fundamentally important to use Genode as a general-purpose
|
||||||
|
system. Now that we have reached most of the feature set that we longed after,
|
||||||
|
the project adjusts its focus. According to our recently published
|
||||||
|
[http://genode.org/about/road-map - roadmap], the underlying theme of the
|
||||||
|
current development shifted towards the cultivation of the existing feature
|
||||||
|
set rather than the introduction of new functionality. The current release
|
||||||
|
perfectly reflects this change. It introduces a highly modular tool kit for
|
||||||
|
scaling up the project's automated testing efforts and comes with stability
|
||||||
|
and performance improvements all over the place. In particular, we are happy
|
||||||
|
to report substantial performance gains of our version of VirtualBox running
|
||||||
|
on NOVA.
|
||||||
|
|
||||||
|
As a second focus of the version 15.02, our custom base-hw kernel platform
|
||||||
|
received a lot of attention. The most prominent news is the added support
|
||||||
|
for virtualization on ARM. This line of work has been conducted and refined over
|
||||||
|
the time span of more than a year and took much of our prior experience with
|
||||||
|
the NOVA virtualization architecture and ARM TrustZone into account. This
|
||||||
|
experience resulted in a novel microhypervisor design with an extremely
|
||||||
|
tiny foot print with respect to the added complexity on the account of
|
||||||
|
virtualization support. In fact, less than 1000 lines of code had to be added
|
||||||
|
to the root of the trusted computing base. Besides virtualization
|
||||||
|
support, our kernel's scheduler got refined to take IPC relationships into
|
||||||
|
account while additionally gaining support for the USB Armory hardware platform.
|
||||||
|
|
||||||
|
These and many more improvements are covered in more detail by the
