Compile error in Foundations book
by Guido Witmond 13 Jun '22

13 Jun '22

Hi Norman, I spotted a compile error in the Foundations book. Page 33 section void _handle_timeout() { log("woke up at ", _timer.elapsed_ms(), " ms"); } /home/user/genode/repos/lab/src/app/hello/main.cc:15:5: error: ‘log’ was not declared in this scope; did you mean ‘Genode::log’? I guess this is an oversight as it is the first example that's worth copy/paste and try out.. Cheers, Guido. PS. I've restarted my Genode experiments, this time with my APU4. I hope to turn it into a simple edge router for my home network... When it works I want to do a genodians blog on it.

Good day! I want to compile my network http golang sample using the following command make -C build/arm_v8a/ KERNEL=hw BOARD=virt_qemu run/go_http Where I can find example of usage virtio nic for arm ?

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.

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
