Road Map for 2019 | 2019-01-15
##############################
| In 2019, we will focus on practical use cases, on interoperability, and
| on harmonizing Genode with existing applications and programming languages.
The past Year of Sculpt was dedicated to bringing Genode to the desktop on
commodity PC hardware. Now is a good time to focus on making the Sculpt OS
relevant and appealing for a broader community. The road map for 2019 features
three major ambitions towards that goal. First, making Genode easier
approachable and usable by presenting practical use cases while fostering a
stronger sense of community among users and developers. Second, simplifying
the use of existing applications and programming languages in Genode-based
systems. And third, improving the interoperability of Genode with existing
protocols and systems.
The complete story behind the new road map is presented at the
[https:/about/road-map - road-map page].

base.
Besides Sculpt, we set forth a number of other goals one year ago.
:The transition from NOVA to our custom kernel and seL4: is ongoing but
the topic received less attention than originally planned. This has
two reasons. First, Alexander Boettcher's excellent maintenance and gradual
improvement of NOVA keeps us hooked. Over the past year, there has been not
much incentive of actual Sculpt users to move away from NOVA. Second, there
is renewed interest in NOVA beyond our use of the kernel. Most specifically,
we started joining forces with
[https://cyberus-technology.de - Cyberus Technology] to improve NOVA
together. That's fantastic!
This development notwithstanding, we still follow our ambition to bring the
support for the other kernels like seL4 on par with NOVA to give Genode
users the ultimate choice.
Speaking of seL4, throughout the year, we have continuously adapted Genode
to the kernel's upstream development and enjoy the informal collaboration
with seL4 developer community. That said, the seL4 version of Genode still
remains a side activity with no commercial backing.
:NXP i.MX: support has become much better, particularly with respect to
network support and performance. Our ongoing commitment to the i.MX
platform is also fueled by privacy-advocating projects like the Librem
phone that are based on the same SoC.
:Software quality and resilience: ultimately became the title story of the
[https://genode.org/documentation/release-notes/18.11#Raising_the_bar_of_quality_assurance - release 18.11].
We greatly intensified the amount and quality of testing, explored static
code analysis, and vastly scaled up the complexity of workloads carried
by Genode.
:System monitoring, tracing, profiling: remains a somewhat underdeveloped area
of Genode. As a step in the right direction, we introduced a simple
trace-logging tool. Also, Sculpt's introspection features like the ability
to inspect the runtime's state live on the machine make Genode's behavior
easier to capture and to understand. But that said, the use of these
features remains a black art mastered only by a few.
:Java: has found its way into Genode via our port of OpenJDK. Details such as
the enabling of the JIT engine on ARM took much more effort than anticipated.
We are happy to report that Tomcat works fine. But at the current state, it
is still too early to advertise Java as a stable feature.
2018 - The year of Sculpt 2019 - Bridging Worlds
######################### ######################
The "Turmvilla" era lies behind us. So let the "Sculpt" era begin! We dedicated the year 2018 to prove that Genode scales to general-purpose
computing. [https://genode.org/download/sculpt - Sculpt OS] leaves no doubt
about that. The logical next step is to make Sculpt OS relevant and appealing
for a broader community.
During our public road-map
[https://lists.genode.org/pipermail/users/2018-December/006517.html - discussion]
on our mailing list, we identified three ways towards that goal:
Having used Sculpt over the past few months, we feel confident to make the # In order to capture the interest of new Genode users, we have to

steps: With practical use, we refer to both desktop computing and headless
scenarios like network appliances and servers. Over the course of 2019,
we plan to establish (variations of) Sculpt as an attractive foundation for
those application areas, and advance Genode's protocol stacks (storage and
encryption come in mind) and hardware support (e.g., ARM 64-bit) accordingly.
# Sculpt for Early Adopters (EA) This will go hand in hand with making Genode easier to discover and to use,
describing use cases at a digestible level of detail, and fostering the
sense of one community that includes both users and developers.
The current version of Sculpt accompanied with plain-text documentation # Since an operating system is only valuable with applications, we have

notion of an operating system (like basic menus and window borders).
There will be a ready-to-use ISO image for Sculpt TC. So users won't need
to be familiar with Genode's source code and build system. As with Sculpt
EA, Sculpt TC will still rely on the user's ability to use Vim.
# Sculpt by Visual Composition (VC)
Whereas the earlier versions rely on text editing for sculpting the system,
Sculpt VC will feature an interactive graphical user interface, which will
hopefully make the system tangible for users who live outside the terminal.
# Sculpt as a Community Experience (CE)
Sculpt CE will allow anyone to play the role of a component provider.
Each user should be able to pick individual components or entire component
compositions provided by others while maintaining complete control over the
system.
In addition to working on Sculpt as the overall theme of the year, we will
focus on the following topics:
:Gentle transition from NOVA to our custom kernel and seL4:
NOVA used to be our kernel of choice on x86 platforms. However, since the
kernel is no longer actively developed, we had to take over the
responsibility to maintain it. Whereas we feel confident in developing the
kernel in an evolutionary way, the kernel has long-standing architectural
limitations (i.e. kernel-memory management) that would require invasive
changes. Instead of ramping up our engagement with NOVA, we'd like to focus
on our custom kernel (base-hw) and the seL4 kernel. In 2018, we set out to
enable Sculpt on base-hw. This involves the support for SMP, VT-x, and VT-d
on x86.
:Freescale i.MX:
Based on the feedback from our community, Freescale i.MX support is of
great interest, specifically i.MX6. Hence, we plan to improve the driver
support for this SoC.
:seL4:
We will try to apply all improvements of Genode on seL4 whenever feasible.
It also goes without saying that we will track seL4's upstream development.
:Software quality and resilience:
The modernized framework API introduced last year is an important stepping
stone. But there is much more we can (and should) do, I.e., learning from
the high-integrity computing community (e.g., implementing critical
components in SPARK), leveling-up the scope and intensity of our automated
tests, facilitating static code analysis, and employing software-hardening
techniques. Of course, this scope goes far beyond the time frame of one
year. The immediate prioritization of these topics will largely depend on
the focus of commercial users funding the work.
:System monitoring, tracing, profiling:
The interactive use of Sculpt along with the prospects enabled by Genode's
GPU support motivate us to optimize Genode towards low-latency multimedia
applications. We will ultimately need to gain a deep understanding on
inter-component interactions, in particular along time-critical data paths.
Therefore, we plan to improve the tooling and cultivate the use of our
existing but underused tracing support.
:Java:
By the end of 2018, we want to enable Genode to leverage the ecosystem
around Java, which is - according to the TIOBE index - the most popular
programming language.
