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.

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
