Road Map for 2023 | 2023-01-17
##############################
| In 2023, we will make the mobile version of Sculpt OS fit for end users,
| unleash advanced hardware features of Intel platforms,
| switch to C++20 by default, and run the feature-complete PC version
| of Sculpt OS on Genode's custom-tailored microkernel.
After having enabled all hardware features of the PinePhone that are
fundamental for a mobile phone over the course of the past year, the
project now aims at getting the mobile version of Sculpt OS into the hands of
end users. Throughout the year, there will be multiple rounds of field tests
within the community, allowing us to reach the desired state of maturity and
usefulness in an iterative way.
On PC platforms, Genode will increasingly address advanced platform features
like the distinction between power-efficient and high-performance cores, the
management of temperatures and frequencies, or the practical use of
suspend/resume. By the end of the year, we envision the PC version of Sculpt
OS running on Genode's custom-tailored microkernel leveraging all those
aspects of modern PC hardware.
Along the planned timeline of the project, one can spot plenty of additional
topics of interest such as the continued line of work of combining Genode
with FPGAs, applications implemented in Rust, the integration of IPv6, the
use of C++20 by default, or completed driver support for the MNT Reform laptop.
An exciting year lies ahead of us!
More details including our reflections of the past year, this year's focus,
and a rough schedule are presented at our official

Review of 2021 Review of 2022
############## ##############
Genode's year 2021 was defined by three extremely challenging lines of work. The two main topics of 2022 went hand in hand. First, we reimagined Genode's
driver landscape across x86 and ARM, universally adopting a new method of
reusing Linux drivers to great success, and rigidly applying the framework's
security architecture to driver components. This effort unlocked the second
major achievement, namely the use of Genode as mobile OS on the PinePhone.

When reviewing the road map for 2021, some items remained uncovered. In
particular the seL4-related topics became stale. At the end of 2020 - when we
assembled the road map for the past year - there was a tangible prospect of
pursuing this topic as funded work. However, those plans were repeatedly
deferred and remained uncertain. Also, there are some items that have seen
healthy doses of progress - like the topics related to Ada/SPARK or Goa - but
received less attention than anticipated. On the other hand, the four releases

of 2021 covered quite a few topics not advertised at the road
map, e.g., webcam support, Xilinx Zynq, or RISC-V.
It is fair to say that the level of technical risks we took in 2021 had been
unprecedented in Genode's development history. We are more than proud of the
outcome, which will hopefully propel Genode to new heights in 2022.
2022 - Mobile Usability 2023 - Rocking the platforms we support!

support (peeking at Vulkan), and making suspend/resume a regular feature that
just works.
These efforts will be flanked by continuous architectural work that will make
the framework ever cleaner and leaner, e.g., by reducing the reliance on
complex C++ features like exceptions, and continuously simplifying the
framework fundamentals and interfaces. On our mission to attain least
complexity of the base system, we strive to host the fully featured PC version
of Sculpt OS on Genode's custom-tailored microkernel by the end of the year.
In addition to the overarching theme outlined above, the following additional
topics stood out during our yearly brainstorming session on the mailing list.
First, several developers expressed their curiosity in working on AMD graphics
(display and GPU) as a side activity. A second recurring topic was the
usability of Genode as desktop OS, easing the work with files on Sculpt,
supporting Drag'n'Drop, tightening the work-flow integration of app-VMs
using the light-weight Seoul VMM, or the use of Qemu on top of Genode for
cross development.
Even though those topics are absent from the timeline below, we can expect
improvements in these areas throughout the year.
