Announcement: Genode OS Framework version 22.05 released
by Christian Helmuth 31 May '22

31 May '22

A fresh release was just released and covers several challenging topics while accomplishing the goals set forth in our roadmap. The most prominent new feature is the support for WireGuard virtual private networks in a dedicated native Genode component. Thereby, easy-to-use state-of-the-art network security becomes available to Genode/Sculpt OS users. Further, we finished our update of PC device drivers to Linux 5.14.21. This includes Intel graphics support up to Gen12 as well as Intel Wi-Fi for 802.11ax. Also, Genode attains the principle ability for voice calls on the PinePhone. Last but not least, the release comes with a revised tracing framework incl. Sculpt OS support and dynamic FPGA device management on Xilinx Zynq paving the way to runtime hardware reconfiguration by a snap of your fingers ;-) The topics of the current release are: - New WireGuard VPN component - New generation of DDE-Linux-based PC drivers - Feature-complete USB host-controller driver - Intel wireless stack with support for 802.11ax - Intel display driver supporting generations 11 and 12 - Modernized platform driver for PC hardware - Dynamic device management and SD-card support on Xilinx Zynq - PinePhone with custom SCP firmware and basic telephony - New revisions of Genode Foundations and Platforms documents - Improved usability of light-weight event tracing The complete release documentation can be found at the usual place https://genode.org/documentation/release-notes/22.05 Happy hacking -- Christian Helmuth Genode Labs https://www.genode-labs.com/ · https://genode.org/ https://twitter.com/GenodeLabs · https://genodians.org/ Genode Labs GmbH · Amtsgericht Dresden · HRB 28424 · Sitz Dresden Geschäftsführer: Dr.-Ing.

Genode porting guide
by Norman Feske 25 May '22

25 May '22

Hello everyone, I am happy to announce the release of the second edition of the Genode Platforms document today: https://genode.org/news/genode-soc-porting-guide The document condenses two years of practical work with enabling Genode on a new hardware platform, taking the PinePhone as concrete example. I hope that by publicly sharing our former in-house know-how in the form of a practical guide, we can lower the barrier of moving Genode to new devices, and generally invite the use of the framework as an experimentation ground. The document is freely available as PDF: https://genode.org/documentation/genode-platforms-22-05.pdf Cheers Norman -- Dr.-Ing.

Genode with Trustzone
by Vasan VS 25 May '22

25 May '22

Hi Genodians, I was extremely thrilled to read through the extensive documentation on how Genode has been experimented with Trustzone of ARM available at: https://genode.org/documentation/articles/trustzone I am very interested to know if the same has been experimented on the latest ARM cores/SoCs that are there in the market currently and any feedback on that. Regards Vasan

Network Mounts On Sculpt
by John J. Karcher 24 May '22

24 May '22

Hello Everyone, After just reading articles and tinkering on the surface for all these years, it is a satisfying feeling to finally dig deeper into setting up a daily driver system. And some of the packages I see in the depots (e.g., Thunderbird) indicate that the transition to native Genode (as opposed to Linux VMs) may be quicker than I expected! One thing I do need to resolve is mounting network shares in Genode. The VFS is obviously designed for things just like this, but I'm having trouble finding detailed info on this topic. Could someone point me in the right direction for how to set this up? I am currently using NFS, but I will gladly switch to SSHFS or anything else that works. Thanks! -- John J.

Launchers 101
by John J. Karcher 19 May '22

Hello, Is there an introductory article about creating launchers in Sculpt, preferably from the config for a running component? I thought I saw something like that, but I can't seem to find it. Thanks! -- John J. Karcher devuser(a)alternateapproach.com

error in building boot image Sculpt OS
by vasvi sharma 16 May '22

16 May '22

Good Afternoon I am new to Sculpt OS and I was working on building genode from source code and then later on building boot image (sculpt OS). I faced an issue while working on the boot image when I run the following line : make -C build/x86_64 run/sculpt KERNEL=nova BOARD=pc Error presented with and without debug in the image shown below (image 1 and 2) . I also noticed the error changed if I revert the changes I made in build.conf for building genode from source code (image 3) asboth the process required modifying the same file. This was the official document like via which I tried to build boot image : https://genode.org/documentation/articles/sculpt-22-04#Building_the_boot_im… How should I resolve this issue ? Thanks Vasvi

VirtualBox Questions
by John J. Karcher 15 May '22

15 May '22

Hello Everyone, Moving my main VistualBox VM to Sculpt has been mostly successful (and very encouraging), but I have two main problems that are keeping me from switching to it as the daily driver. Hopefully these are easy questions... 1. How do you specify the window size of the VM? 2. I need to use "Bridged Networking" for access to certain things on my LAN, but it looks like the VM is using NAT. I have tried poking around in the vbox6 file, but I don't know if there is more to it than that. Any help would be appreciated! Thanks! -- John J. Karcher devuser(a)alternateapproach.com

restarting child components with resource saturation
by Duss Pirmin 12 May '22

12 May '22

Hello Genodians We have a somewhat complex scenario consisting of a hand full of components and (sub-)inits. The outermost deploy-config starts, besides others, the following components: - vfs - report_rom and other helper components - init (drivers runtime) - init (management runtime) - init (dynamic runtime, ram/cap saturation) The runtimes are configured via a deploy-config. Most components and runtimes depend on the file system provided by vfs. When restarting vfs by incrementing the version attribute, some components that depend on vfs don't get any resources any more after being restarted. In the state reports of init I see that the RAM quota for some subsystems decreases after the restart of vfs. For some it increases for a short time but goes back down again. For most, including dynamic runtime, it stays constant for the whole time. I wasn't able to create a simpler example that shows the same error. Does anybody have an idea in which direction I could investigate? Best regards, Pirmin

One Small Step For Genode...
by John J. Karcher 12 May '22

12 May '22

... one giant leap for a Genode enthusiast! ( OK, I exaggerated - it's not really a step for Genode at all, but it is a huge leap for me! ;^) ) After being extremely short of time for about a year, I finally used the 22.04 release to take my first steps toward using Genode as my daily driver OS, mainly by using VirtualBox 6 to run my existing VMs under Sculpt. I still have some problems to work out before I can make the official transition, and I will probably have a fair number of "new user" questions here soon, but I am highly impressed with the state of the system. In the beginning, I will probably continue to do most tasks within the Linux VMs, but I am really looking forward to gradually shifting applications to running directly on Genode as they (or native alternatives) become available. If any daily users have tips to share, I'll certainly be listening! (If I come up with anything helpful, I will try to write it up for Genodians also.) One thing I am very curious about is the state of the various packages in the depots - some of those look very intriguing! The bottom line: Thanks to the Genode devs and community members for making this possible! Happy Sculpting! John J. Karcher devuser(a)alternateapproach.com
