Roadmap 2024
by Norman Feske 19 Jan '24

19 Jan '24

Hello everyone, in his most recent posting, Credric already noted that now is the time of year again to reflect on our achievements of this year and to anticipate topics to pursue next year. To keep up with this fine tradition, let me kick off our road-map discussion with my personal perspective. Reflections of 2023 As indicated by the overarching theme of the last roadmap "Rocking the platforms we support!", Genode's four releases of 2023 had a strong focus on low-level platform work. This has been especially visible on modern PC platforms like the Gen12 Framework laptop I have under my fingertips right now. At the beginning of 2023, Sculpt OS was in principle working on this machine, but with compromises that spoiled the user experience: fan noise, an erratic touchpad (using the firmware's PS/2 emulation), Fn key having no effect, strange issues when re-plugging an external display, and no indication of the battery state. In the meantime, not only are all these rough edges gone, but we even gained the ability to exercise precise control over the machine' performance/frequency/temperature/power characteristics using an interactive GUI. I think it's fair so say that Genode advanced far beyond the state of "working" and has entered the territory of "rocking". I wish to name four further personal highlights of the year: First, we got the mobile version of Sculpt OS into the hands of a pilot group of users who provided instructive feedback to us. From my perspective, the system-update mechanism that I created for this purpose turned out to be an almost pivotal point in the evolution of Sculpt OS because it reduces the effort and risk of test-driving experimental versions to almost zero. It was a pleasure to see how e.g., Johannes leveraged this new way of gathering feedback for his IOMMU line of work. Providing system images for testing has become a second nature. Second, the road map for 2023 envisioned Sculpt OS running on our custom base-hw kernel on the PC. We identified DMA protection and virtualization support as the two remaining showstoppers. With much excitement, I followed how both of these deeply technical topics got covered over the course of the year. Third, Goa finally emerged from a personal project of mine to an official Genode project led by Johannes. I'm stunned how much the project benefited from this change. All of the remaining backlog of my vague plans - I'm thinking of the index-project support or bash completion - got eventually realized in a way true to the spirit of the project. The fate of the Goa tool makes me immensely happy. Fourth, during the first half of the year, I found myself intensively working on Genode's new debug-monitor component, pursuing the idea to implement a debugging instrument as a specialized version of init augmented with the GDB protocol. This engagement was pretty much motivated by a customer. The result of my initial work then seamlessly transitioned into the hands of Christian Prochaska who did a marvelous job with steadily advancing this line of work towards our joint vision of on-target debugging on Sculpt OS. The technical feats notwithstanding, I found the frictionless way of collaborating a pure joy. Besides the highlights above, one topic close to my heart was the creation of the dialog API that I designed as necessity to make the code of Sculpt's administrative user interface maintainable and easy to extend in the longer run. Plans for 2024 After concentrating so intensively on topics below the surface, I now long for reaping user-visible rewards. Speaking of the dialog API just mentioned, I see potential in using this new infrastructure for Genode-native applications and immediately think of the file manager that I already wanted to tackle this year. But I also have plenty of ideas to make Sculpt OS more user friendly. What about presenting the README files of software packages directly in the GUI? Making the component graph scrollable? Allowing the user to select an arbitrary directory as a file system to a component? Buttons for saving the current deployment or the settings? Beyond Sculpt's administrative user interface, I'd also like to attend the GUI stack. I think of refining the GUI-session interface to remove tearing artifacts, to better support desktop-UI-paradigms like drag'n'drop, and to explore the opportunity of using nitpicker's mechanisms at the application-level, not only at the window-composition level. Hence, I'd condense my ambition for the next year to "Sculpt OS usability". Device-wise, I'm going to continue my engagement with the PinePhone and look forward to the upcoming MNT PocketReform laptop. Above I presented my personal view. How about your's? I would very much appreciate you sharing your feedback, ideas, concerns, and plans regarding Genode. How are your interests aligned with the perspective shared above? Do you see specific pain points that deserve the attention of Genode's core developer team? What is your perspective on Genode's past year's accomplishments? Can you share your ambitions or even concrete plans? How and where would you like to see Genode at the end of 2024? Cheers Norman -- Dr.-Ing.

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
