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

Extending the VFS with hard-links
by Rumen Mitov 03 Apr '25

03 Apr '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

Hard-Links in Genode

Hello, Does Genode's VFS have the capability to create hard links? So far as I have been able to tell it is only possible to create symlinks. Best, Rumen

Announcement: Genode OS Framework version 25.02 released
by Norman Feske 28 Feb '25

28 Feb '25

I'm happy to announce the release of version 25.02 of the Genode OS Framework. https://genode.org/news/genode-os-framework-release-25.02 The first release of the year already pays tribute to our road-map theme "rigidity, clarity, performance" by introducing SIMD-based graphics optimizations, revising and simplifying central parts of our custom base-hw kernel, while also lifting long-standing scalability limitations when using 3rd-party kernels like seL4 and Fiasco.OC. In addition to this careful gardening work, the release is not short of features either. The headlines of the release documentation are the extension of multi-monitor support to the window manager and virtual machines, the updated port of the Chromium engine along with the Falkon web browser, and Qemu as native Genode component. The highlights of the new version at a glance: - Multi-monitor window management - Multi-monitor virtual machines - SIMD optimizations - Port of Qemu via Goa - Web Engine updated to Chromium version 112 - User-space IOMMU support for IRQ remapping - Sculpt OS on Intel Meteor Lake platforms - Goa SDK improved for building shared libraries - New board support for F&S i.MX 8MP armStone All the details behind these (and more) topics of the new version are given in release documentation: https://genode.org/documentation/release-notes/25.02 Norman -- Dr.-Ing.

GDB Hangs After Continue
by Rumen Mitov 26 Feb '25

26 Feb '25

Hello, I was trying to debug my program with GDB, however after connecting to the binary, loading all the appropriate files, and running "continue", GDB just hangs and it does not produce any output. Here are the exact steps I took: 1. Inserted wait_for_continue() in my code 2. make -C build/x86_64/ run/squid KERNEL=linux BOARD=linux & 3. ps -ef | grep squid 4. gdb -p <port number from previous command> 5. symbol-file build/x86_64/debug/squid 6. add-symbol-file build/x86_64/debug/ld-linux.lib.so 7. continue (GDB hangs, I have to CTRL-c it) Did I perhaps miss a step? Best, Rumen

Goa: Cannot get sub-node from XML
by Rumen Mitov 19 Feb '25

19 Feb '25

Hello, I am trying to migrate my project to the Goa build system. However, when I try running Genode throws 'Genode::Xml_node::Nonexistent_sub_node'. Below I have provided a simplified file containing the isolated code from where the error is thrown along with the full runtime file. Line 13 is the where the error is thrown from. I cannot figure out why this is not working, since it works just fine with the traditional build system (i.e. with make). Any help will be greatly appreciated! Best, Rumen

Kernel: Cpu 2 error: re-entered lock. Kernel exception
by Pirmin Duss 12 Feb '25

12 Feb '25

Hello Genodians Since we rolled out the update to 24.11 we see the above message about once or twicw a day in the logs of our testing pipeline. It happens on different hardware (Up-Xtreme and imx8mp_iot_gate in the last two days) and in different run scripts. The run scripts range from a fairly simple TPM run script to complicated run scripts that test the resilience of the operating system to stopping/starting of whole subsystems and reboots. Currently we don't have a case where this happens reproducible. It could be related to https://github.com/genodelabs/genode/issues/5382 but also something completely different. How could we narrow down the issue and gather logs to identify the cause of it? Kind regards, Pirmin

Trying to modify Bit_array throws 'Invalid_index_access'
by Rumen Mitov 24 Jan '25

24 Jan '25

Hello, I am facing a problem when using the Bit_array class. I have a class called L1Dir which contains the property freemask which is a Bit_array with L1_SIZE bits. I want to initialize every bit to value 1 in freemask. However, when I try to call freemask.set(0, L1Dir) outside of the L1Dir default constructor the following error is thrown: 'Genode::Bit_array_base::Invalid_index_access'. I have tried changing the call to freemask.set(1,2) but I still get the same exception. I have also tried with freemask.get(...) and freemask.clear(...) with no success. I have initialized freemask with enough space: Genode::Bit_array<L1_SIZE> freemask; This leads me to believe that the problem has something to do with the underlying memory of Bit_array_base. If you know what I am doing wrong, please let me know! Best, Rumen P.S. If you need more context, you can find the current state of my code here: https://github.com/rumenmitov/genode-squid/tree/a726c5da3099a7f5de1d4d3d98a…
