Announcement: Genode OS Framework version 25.05 released
by Christian Helmuth 28 May '25

28 May '25

Hello everyone, I'm happy to announce the May 2025 release of Genode. https://genode.org/documentation/release-notes/25.05 According to this year's motto "rigidity, clarity, and performance", the Genode 25.05 release focuses on API safety, consolidation work, and developer tooling.The most prominent change in this release is the much revised framework API that no longer relies on the C++ exception mechanism but precisely encodes all possible error conditions as sum types, an inspiration taken from the Rust-language community. This approach rules out several classes of programming errors by design and, thus, enforces the conscious handling of error conditions, eliminates the accidental leakage of pointers, as well as promotes clarity of object ownership and lifetimes. The fair amount of consolidation work in the this release includes, for example, the unified integration of the Linux and lwIP TCP/IP stacks paving the ground for subsequent network-protocol improvements and optimizations. Feature-wise, we add a new VFS plugin for generating pseudo random numbers, support for touch gestures, and display rotation and flipping on Intel hardware. Also following our biennial update routine, we use a recent tool chain based on GCC 14.2, binutils 2.44, and GDB 16.3 starting with this release for the next 24 months. Further, the Goa SDK now mitigates security risks while importing, building, and testing projects of unvetted origin by sandboxing all tools and tightly restricting the reach of its own configuration files. The current release contains the following changes and new features: - Tool chain upgraded to GCC 14.2 and binutils 2.44 - Hardened API, leveraging sum types for error handling - Security-enhanced Goa SDK - New support for touch gestures - New VFS plugin for generating pseudo random numbers - Revisited integration of the Linux and lwIP TCP/IP stacks - Display rotation and flipping on Intel hardware - Dynamic mode switching and reporting of the VESA display driver Read the complete release documentation for the version 25.05 here https://genode.org/documentation/release-notes/25.05 Best regards -- Christian Helmuth Genode Labs https://www.genode-labs.com/ · https://genode.org/ https://floss.social/@genode · https://genodians.org/ https://de.linkedin.com/company/genodelabs Genode Labs GmbH · Amtsgericht Dresden · HRB 28424 · Sitz Dresden Geschäftsführer: Dr.-Ing.

laptop boots fine into 25.04
by Guido 16 May '25

16 May '25

Hi Genodians, At the Hack-n-Hike, I ran into a boot loop after upgrading Sculpt 24.10 to 25.04. However, when I test with a fresh 25.04 image from the website (sha256: 54e8bd...), the very same laptop boots OK. However, I do run into an issue when I upgrade from 24.10 to 25.04 but I'll investigate first before reporting or requesting help. Thanks for the wonderful HnH. Cheers, Guido.

Extending the VFS with hard-links
by Rumen Mitov 02 May '25

02 May '25

Hello, I need some help with extending the VFS for my project. I need hardlink support, so I added the following to repos/os/include/vfs/directory_service.h's Directory_service struct: virtual int hardlink(char const *path, char const *hardlink_path) { (void) path; (void)hardlink_path; Genode::error("not implemented!"); return 0; } I have the Lwext4 plugin (https://codeberg.org/jws/genode-wundertuete/src/branch/import-lwext4_from_w…) setup for my project so I then extended repos/wundertuete/src/lib/vfs/lwext4/vfs.cc's Lwext4_vfs_file_system struct: int hardlink(char const *path, char const *hardlink_path) override { return ext4_flink(path, hardlink_path); } The problem is that hardlink uses the default implementation in my main code: squidutils->_vfs_env.root_dir().hardlink(p2.string(), p1.string()); // Prints 'not implemented' From what I have read online the issue is that squidutils->_vfs_env.root_dir() is of type Directory_service, whereas I need it to be Lwext4_vfs_file_system. However, Lwext4_vfs_file_system is declared in the vfs.cc file above as opposed to being declared in a header. Is there a way to use Lwext4_vfs_file_system without copying the entire source of Lwext4 into my project's source code? Or am I perhaps going in the wrong direction with all of this? Best, Rumen

Announcement: Sculpt OS version 25.04 released
by Norman Feske 30 Apr '25

30 Apr '25

Hello everyone, with delight, I'm announcing the release of Sculpt OS 25.04: https://genode.org/news/sculpt-os-release-25.04 As one highlight, the new version wraps up our intensive work on multi-monitor support by bringing multi-monitor awareness to the window-management level, adding new keyboard shortcuts for the use of virtual desktops, and even going as far as offering display rotation. Please revisit the window-management section of the documentation for a brief overview of the niceties: https://genode.org/documentation/articles/sculpt-25-04#Window_management Another user-empowering improvement is the new ability to select arbitrary directories as file systems when integrating a new component. This alleviates the need to manually maintain dedicated chroot instances: https://genode.org/documentation/articles/sculpt-25-04#File_system Third, the highly anticipated update of the Falkon browser to a recent Chromium engine is now available. You can give it a try using the ready-to-use preset. Among the many other improvements are enhanced IOMMU support, compatibility with Intel Meteor Lake, various performance optimizations, and UI controls for changing the screen resolution of the VESA driver. If you already use Sculpt OS on your machine, you can conveniently switch to the new version by selecting 2025-04-29 offered by genodelabs in the system-update dialog. New users can find the new version readily available as system image for the PC, PinePhone, and the i.MX8-based MNT Reform laptop. https://genode.org/download/sculpt Thanks to everyone who contributed to the release, be it in the form of technical work, testing, or feedback. Speaking of feedback, please don't hesitate to drop by in the community forum: https://genode.discourse.group Happy Sculpting! Norman -- Dr.-Ing.

Chromium Browser on Sculpt OS?
by Lonnie Cumberland 07 Apr '25

07 Apr '25

Hi All, Hope that everyone is doing well today. Been away from Genode for a while but am making it back around and am exploring Sculpt OS a bit. I was able to boot it up on an Intel NUC7 with no problems and was interested to try and find out if it can run Chromium web browser? In particular, I am interested in exploring the possibility of setting up a Sculpt OS based kiosk in fullscreen mode at boot time running Chromium browser. To test this, I wanted to try and find out how to boot it up on Sculpt. Any thoughts would be greatly appreciated. Cheersand have a great day, Lonnie

Hello, Does Genode's VFS have the capability to create hard links? So far as I have been able to tell it is only possible to create symlinks. Best, Rumen

Announcement: Genode OS Framework version 25.02 released
by Norman Feske 28 Feb '25

28 Feb '25

I'm happy to announce the release of version 25.02 of the Genode OS Framework. https://genode.org/news/genode-os-framework-release-25.02 The first release of the year already pays tribute to our road-map theme "rigidity, clarity, performance" by introducing SIMD-based graphics optimizations, revising and simplifying central parts of our custom base-hw kernel, while also lifting long-standing scalability limitations when using 3rd-party kernels like seL4 and Fiasco.OC. In addition to this careful gardening work, the release is not short of features either. The headlines of the release documentation are the extension of multi-monitor support to the window manager and virtual machines, the updated port of the Chromium engine along with the Falkon web browser, and Qemu as native Genode component. The highlights of the new version at a glance: - Multi-monitor window management - Multi-monitor virtual machines - SIMD optimizations - Port of Qemu via Goa - Web Engine updated to Chromium version 112 - User-space IOMMU support for IRQ remapping - Sculpt OS on Intel Meteor Lake platforms - Goa SDK improved for building shared libraries - New board support for F&S i.MX 8MP armStone All the details behind these (and more) topics of the new version are given in release documentation: https://genode.org/documentation/release-notes/25.02 Norman -- Dr.-Ing.

GDB Hangs After Continue
by Rumen Mitov 26 Feb '25

26 Feb '25

Hello, I was trying to debug my program with GDB, however after connecting to the binary, loading all the appropriate files, and running "continue", GDB just hangs and it does not produce any output. Here are the exact steps I took: 1. Inserted wait_for_continue() in my code 2. make -C build/x86_64/ run/squid KERNEL=linux BOARD=linux & 3. ps -ef | grep squid 4. gdb -p <port number from previous command> 5. symbol-file build/x86_64/debug/squid 6. add-symbol-file build/x86_64/debug/ld-linux.lib.so 7. continue (GDB hangs, I have to CTRL-c it) Did I perhaps miss a step? Best, Rumen
