Hi Paul,

This line of work (conducted by Sebastian Sumpf) has been merged into
master. See the following commits for more details:




We still need to thoroughly test the new solution on real hardware and
at least one virtualization solution (i.e., VirtualBox). For the
release, we plan to document the design of the new interface and the
rationale behind it.

> -IOMMU support on NOVA

This topic is being worked on by Alexander Böttcher. See here:


In addition, Alex largely refined the base-nova code to enable dynamic
workloads on this kernel. This work includes pretty substantial changes
of the kernel. These changes are available in his fork of the kernel:


> -First steps of user-interface concept
> --UI concept for pleasant working environment
> --Tiled window manager
> --Terminal improvements (e.g., scroll buffer)
> --Noux improvements (e.g., signals)

These points remain largely unaddressed. I expect that we will see
progress on them after FOSDEM. I will certainly be involved in these topics.

> -Improved x86 virtualization support
> --Improved virtualization support (Vancouver on NOVA)

There is an open pull request about this topic:


Udo Steinberg agreed to revisit the patches to incorporate my feedback.
After that, we will integrate them into staging and document and test
the new version of the Vancouver VMM.

In addition to the mentioned topics, the February release will bring
principal support for the Exynos5-based Arndale platform for our custom
base-hw kernel. See Martin Stein's topic branch:
