key..... lacks Qt mapping
by ttcoder＠netcourrier.com 08 Dec '23

08 Dec '23

Fellow Genodians, I'm reaching "alpha" stage (or a good approximation thereof) of my "distro" project at last, added a depot manager that mimics the one in ScultOS, so that the distro can download and use the wealth of packages provided on genode.depot.org. Greatly enjoying my newfound ability to use that software :-) but the one issue that remains is one I can't figure out so far : keyboard input (mostly) does not work, in Falkon and qt5_textedit (I'm assuming, all Qt apps). I'm hitting this warning: https://github.com/cproc/qt5/blob/018e7c70f8d5bb5e000acf203d843317a6394a7d/… Thought of filing a ticket in cproc/qt5/ or in genode-world/, but the most likely explanation is that I'm doing something wrong during system integration. That's in 23.05 ; in 23.08 I can't get networking to function (with ipxe_nic_drv or with the newer pc_nic_drv from the depot) which precludes downloading newer packages instead of re-using the 23.05 revisions. I'll try 23.11 in the next couple weeks. Symptoms and code paths: - 'modifier' keys listed in the QGenodePlatformWindow::_map_key switch() do work (I can move the cursor with the arrow keys, delete) - however, all letters, digits, punctuation, spacebar, fail to work, and output a warning to LOG - each time, the warning says e.g. "key KEY_A,18 U+fffe lacks a Qt mapping" - it's interesting that the unicode is always "fffe" - so the Input::Keycode is correct (it says KEY_A, KEY_B, etc)... - but the Codepoint.value is always incorrect (it's always fffe) ? I'm not setup for working with Qt, so can't add instrumenting in the lib itself or the apps. I was able to find the warning() despite github erroring out on "we're reindexing the site, please come back later" because that file happened to be listed in the recent commits :-) I'm probably doing something wrong, but what ? Only thing I can think of is... - unseen problem when downloading/configuring Qt5 apps, compared to the way SculptOS does it ? - problem with underlying configuration/system-integration ? I use nitpicker and event_filter as per basic .run file examples Thanks for any hint on this, it's driving me nuts, Cedric

CfP: Microkernel and Component-based OS Devroom at FOSDEM 2024
by Martin Decky 15 Nov '23

15 Nov '23

Microkernel and Component-based OS Devroom at FOSDEM 2024 CALL FOR PARTICIPATION On-line version of this CfP: http://fosdem.microkernel.info/ The developers and users of several free and open source microkernel-based, unikernel-based and component-based operating systems will meet as part of FOSDEM 2024 [1] and will share a developer room. The devroom is currently looking for content in the form of talks and other activities related to microkernel-based, unikernel-based, component-based operating systems and similar areas. Possible topics of the devroom include, but are not limited to: * introduction of a specific OS or framework * design of subsystems and the general architecture of an OS * languages, tools and toolchains used * enabling support for hardware (architectures, device drivers) and programming languages * development processes, debugging * maintenance, testing and release engineering * safety, security and robustness * trends and challenges * research and open questions * community and governance * use cases, experiences and status updates * best practices and lessons learned * demos The devroom has been scheduled to Saturday February 3rd 2024 in the afternoon (Central European Time). This is a call for your participation. We kindly ask you to submit your proposals no later than on December 10th 2023 (End of Day, Anywhere on Earth). Please use the pretalx [2] web site to submit your proposals. Note that this is a new submission system and the user accounts from the previous submission system (pentabarf) have not been transferred. Make sure to select the Microkernel and Component-based OS as the track when submitting your proposal and include at least the following information: * title of your proposal * short abstract (one or two paragraphs) * duration (at least 15 minutes and no longer than 40 minutes) * your full name * your short bio You can specify your preferred time slot of your proposal and any other relevant information. The communication language of the devroom is English. Please note that the devroom has been allocated only a half of a day this year. Therefore the final decision on the duration of the talks will be made by the devroom organizers based on the number of accepted proposals. The official devroom schedule (along with the accepted talks) will be announced on December 15th 2023 on the devroom's mailing list [3] and the speakers will be notified via e-mail. The schedule will be published on the FOSDEM web site, too. About the Devroom Since the first Microkernel OS Devroom at FOSDEM 2012 [4], this devroom has been a part of each following FOSDEM (with slight variations of the name). The focus gradually widened to include component-based, unikernel-based and other operating systems. By now, it has become a somewhat institutionalized tradition for the open source operating systems community, a kind of "extended family meeting" and it is one of the places where microkernel and unikernel enthusiasts meet regularly. To this date, over two dozen projects have participated in one way or another. Many of the projects face similar challenges but come up with partially different solutions. Therefore, the goal of the devroom is to bring the various projects together, let them exchange ideas, cross-pollinate and socialize. As every previous year, the devroom will offer the "stage" both to established community members and to newcomers. We like to select the talks in an inclusive manner, while staying true to the main technical topics (system-level software, broadly speaking) and creating a balanced and unbiased schedule. We would like to keep the quality bar of the devroom same as in the previous years. Presenting at FOSDEM implies that the recordings of the talks will be published under Creative Commons license by FOSDEM. By submitting a proposal, the speaker agrees to have the talk made available publicly indefinitely. For organizational purposes, we also need contact information of the speakers of accepted talks. Microkernel Dinner It has also become a habit that the devroom participants dine together somewhere in Brussels. The year 2024 will not be any different, so there is going to be a dinner on Saturday night. We will inform you about the exact arrangements later. About FOSDEM FOSDEM [5] is a two-day conference organized by volunteers to promote the widespread use of free and open source software. FOSDEM is widely recognized as one of the largest and best such events worldwide. FOSDEM covers a wide spectrum of free and open source software and hardware projects and offers a platform for people to collaborate. To this end, FOSDEM has set up developer rooms (devrooms) where teams can meet and showcase their projects. Devrooms are a place for teams to discuss, hack and publicly present latest directions, lightning talks, news and proposals. Besides developer rooms, FOSDEM also offers main tracks, lightning talks, certification exams and project stands. In recent years, FOSDEM has been hosting more than 8000 developers annually at the ULB Solbosch Campus in Brussels, Belgium. The participation in FOSDEM is totally free, although the organizers gratefully accept donations and sponsorship. No registration is necessary. Attendees are expected to follow the FOSDEM's code of conduct [6].

Announcement: Sculpt OS 23.10 released
by Norman Feske 15 Nov '23

15 Nov '23

Hello, it is my pleasure to announce the release of Sculpt OS 23.10: https://genode.org/news/sculpt-os-release-23.10 The highlight is certainly the new ability to fine-tune physical CPU parameters via an interactive user interface, which is especially useful on modern laptops that offer plenty of monitoring and power-management options. As described in the following article, one can watch CPU temperatures and frequencies, dynamically adjust performance profiles, unveil the differences between Intel's P&E cores, and even observe the power draw. https://genodians.org/alex-ab/2023-10-23-msr Besides this most prominent feature, the new version benefits from Genode's advances during the past 6 months. E.g., the former iPXE-based network driver has been replaced by a current Linux driver, the entire software is now consistently built with GCC 12.3, and Sculpt's runtime is now driven by the new monitor runtime paving the ground towards on-target debugging. We made the new version readily available for both PCs and the PinePhone. The latter benefits from several usability improvements such as a screensaver conserving battery power, various UI tweaks, and functional volume buttons. Users of Sculpt 23.04 can switch to the new version via the built-in system-update dialog. New users can find ready-to-use disk images at the Sculpt download page. https://genode.org/download/sculpt Up-to-date Sculpt documentation is available on our website and as PDF. https://genode.org/documentation/articles/sculpt-23-10 https://genode.org/documentation/sculpt-23-10.pdf As you may have noticed on the mailing list, Sculpt 23.10 is the first version that was preceded by several release candidates (RC). Thanks to everyone who gave the RCs a spin. The official release greatly benefited from your feedback! Cheers Norman -- Dr.-Ing.

Beginner questions: Seoul, Rust, DDE, and system composition
by Zachary Zollers 26 Oct '23

26 Oct '23

Hi all, My name is Zach. I am a student at Kansas State University doing research with Dr. Eugene Vasserman (Cc). I have been lurking in the mailing list for some time now and I thought I'd introduce myself and ask a couple of "beginner questions" that I have after reading the Foundations book and playing with Sculpt. [1] Is Seoul still viable for virtualization on Genode? If so, where can I find the documentation for writing a VM configuration? I am partial to Seoul over VirtualBox due to its smaller codebase. I checked the genode-world repository and the original (outdated) source repository, but was unable to find anything. [2] What is the state of rust support for Genode? I have seen a few mentions of it in release notes. Can I make base API calls from rust (e.g., requesting sessions, creating child components, etc.), or is it similar to running applications with the POSIX compatibility layer? [3] Which system calls are provided by the Linux driver environment? Is it viable for running arbitrary Linux applications/services (e.g., a container runtime)? [4] What is the best way to determine the dependencies of a component? How does the Sculpt visual composition system determine which sessions are required? When trying to run a complex component (e.g., a VMM) I often find myself doing a lot of trial and error with including libraries and starting necessary dependencies in the run script. Is there a better, or more consistent, way to determine dependencies? Apologies if any of these questions have obvious answers. If this is the case, I would appreciate a pointer to relevant documentation so I can investigate further. Thanks in advance, Zach
