Road Map
|
|
========
|
|
|
|
|
|
Herein, we lay out our plans for evolving Genode. Progress in addition to this
|
|
planning will very much depend on the degree of community support the project
|
|
will receive. The
|
|
[https://genode.org/about/challenges - Challenges] page collects some of our ideas to
|
|
advance Genode in various further directions.
|
|
|
|
The road map is not fixed. If there is commercial interest of pushing the
|
|
Genode technology to a certain direction, we are willing to revisit our plans.

Review of 2019
|
|
##############
|
|
|
|
For the road map 2019, we picked "bridging worlds" as our guiding theme:
|
|
(1) Lowering the friction when combining existing software with Genode,
|
|
(2) Fostering interoperability with widely used protocols and APIs, and
|
|
(3) Making Genode easier to approach and generally more practical.
|
|
|
|
With respect to (1), we identified Genode's custom tooling (build
|
|
system, run scripts, ports mechanism, depot tools) as a point of
|
|
friction. They are arguably powerful and flexible but require a lot of
|
|
up-front learning. This is certainly a burden unacceptable for a casual
|
|
developer without a black belt in Make and Expect/Tcl. The new
|
|
[https://genode.org/documentation/release-notes/19.11#New_tooling_for_bridging_existing_build_systems_with_Genode - Goa]
|
|
tool rearranges the existing tools in a way that puts the concerns of casual
|
|
developers into focus, allowing for the use of commodity build systems,
|
|
eliminating Tcl syntax from the equation, running sub-second test cycles, and
|
|
streamlining the packaging of software.
|
|
|
|
On account of (2), we
|
|
[https://genode.org/documentation/release-notes/19.05#Broadened_CPU_architecture_support_and_updated_tool_chain - switched to C++17]
|
|
by default, fostered the use of
|
|
[https://genodians.org/ssumpf/2019-02-27-java-19-02 - Java],
|
|
updated Qt5, and put
|
|
[https://genode.org/documentation/release-notes/19.11#C_runtime_with_improved_POSIX_compatibility - POSIX]
|
|
compatibility into the spotlight. We were eventually able to dissolve the need
|
|
for our custom Unix runtime (Noux) because all features of Noux are covered by
|
|
our regular libc now.
|
|
|
|
Our biggest step towards (3) is the [https://genodians.org] website we
|
|
started in winter 2019, which gives individual members of our community
|
|
an easy way to present thoughts, projects, and experiences.
|
|
Complementing Genode's formal documentation, it also conserves practical
|
|
tips and tricks that were previously not covered in written form.
|
|
|
|
When speaking of "bridging worlds", we should not forget to mention the
|
|
tremendous effort to bring Sculpt-OS-like workloads to the 64-bit ARM world.
|
|
Thanks to the added support for
|
|
[https://genode.org/documentation/release-notes/19.08#64-bit_ARM_and_NXP_i.MX8 - multi-core AARCH64],
|
|
hardware-based
|
|
[https://genode.org/documentation/release-notes/19.11#Virtualization_of_64-bit_ARM_platforms - virtualization],
|
|
and network/USB/graphics drivers for the i.MX8 SoC, the flexibility of Sculpt
|
|
OS will eventually become available on PC hardware and ARM-based devices
|
|
alike.
|
|
|
|
Over the course of 2019, we admittedly skipped a few topics originally
|
|
mentioned on our road map. In particular, the user-visible side of
|
|
Sculpt OS received less attention than originally envisioned. We also
|
|
deferred several ideas we had in mind about reworking our GUI stack.
|
|
Instead, we expanded our work in the areas of storage (block-level APIs,
|
|
test infrastructure,
|
|
[https://genode.org/documentation/release-notes/19.11#Preliminary_block-device_encrypter - block encryption])
|
|
and
|
|
[https://genode.org/documentation/release-notes/19.08#Flexible_keyboard_layouts - input processing].
|
|
This shift of focus is mostly attributed to the priorities of Genode Labs'
|
|
customers who fund our work.

2020 - Dwarfing the barrier of entry
|
|
####################################
|
|
|
|
Genode as a technology is there. For more than one decade, we walked unfathomed
|
|
territory, fought with countless deep rabbit holes, took risky decisions,
|
|
tracked back, explored design spaces, developed taste and distaste, pruned
|
|
technical debt, and eventually found formulas of success. Today, there are no
|
|
(fundamental) unsolved questions. All the puzzle pieces are in place. There
|
|
could be no better proof than our daily use of Sculpt OS. The time is right
|
|
to make Genode palatable for a wider circle. We identified four actionable
|
|
topics to achieve that.
|
|
|
|
:User friendliness of Sculpt OS:
|
|
|
|
Until now, Sculpt OS is not exactly friendly towards users who are
|
|
unfamiliar with the Unix command-line tools. Since Sculpt is not Unix
|
|
based, this is a bit paradoxical. 2020 will give Sculpt OS a friendlier
|
|
and discoverable user experience. In this context, we will inevitably
|
|
put our attention to Genode's GUI stack.
|
|
|
|
:Perception of high quality:
|
|
|
|
Compared to commodity operating systems who stood the test of time,
|
|
Genode is a young and largely unproven technology. It understandably calls
|
|
for skepticism. All the more we must leave no doubts about our high
|
|
quality standards. There must be no room for uncertainty. Hence, during
|
|
2020, we will intensify the consolidation and optimization of the framework
|
|
and its API, and talk about it.
|
|
|
|
:Enjoyable tooling:
|
|
|
|
Genode's success at large will depend on developers. As of today, software
|
|
development for Genode requires a huge up-front learning curve. This is
|
|
fine for people who are already convinced of Genode. But it unacceptable
|
|
for casual developers who want to get their toes wet. We should aim for
|
|
tooling that allows new developers to keep up their flow and beloved
|
|
tools. The recently introduced [https://genodians.org/nfeske/2019-11-25-goa - Goa]
|
|
tooling is our first take in this respect. It is certainly too early to call
|
|
Goa a success. In order to find out if we are on the right track, we want to
|
|
expose Goa to as many problems as possible, primarily by the means of
|
|
porting software. Also, things like IDE usage or adapters for a variety of
|
|
build systems will certainly move into focus in 2020.
|
|
|
|
:Convincing use cases:
|
|
|
|
Use cases can give exemplary proof of the fitness of Genode. We already
|
|
took a few baby steps to extend the range of documented use cases beyond
|
|
Sculpt OS last year. The boot2java scenenario comes in mind. 2020 will
|
|
hopefully see several more illustrations of Genode's versatility.
|
|
|
|
|
|
Apart from this overall theme, we plan to continue our commitment to the
|
|
NXP i.MX SoC family, revisit Genode's low-latency audio support, and
|
|
extend the cultivation of Ada/SPARK within (and on top of) Genode.
|
|
|
|
|
