memory dump
by Abhay Amala 05 Dec '15

05 Dec '15

Hi everyone, I am running tz_vmm on imx53qsb and thinking about taking a snapshot of the normal world memory inside the tz_vmm app and put into a file as a raw data. I appreciate if anyone give me a hint. Thanks and best regards, Abhay

Porting Genode to Raspberry Pi 2
by Tamas Bakos 03 Dec '15

03 Dec '15

Hello everyone, I would like to port Genode to the Raspberry Pi 2, using the custom kernel from base-hw. I know it is already available for the Raspberry Pi 1, but model 2 uses an entirely different CPU (ARM Cortex-A7), from a different family (ARMv7-A). I am not very familiar with the structure of the Genode source files yet. Could you help me, by explaining what files I should create or modify, and which files I should take as reference when doing so?(Should I start based on the files of a board using a CPU from the same family (ARMv7-A), or from the files concerning the Raspberry Pi 1?) Thanks,Tamas

Thoughts about a new live system
by Norman Feske 02 Dec '15

02 Dec '15

Hello, shortly after almost every Genode release, I see people wondering why we have not released a new live system since many years. There are even a few who conclude that the project is not going to get anywhere because there is no easy way to try it out. Because this topic is brought up every now and then, I'd like to share my opinion about it: https://github.com/genodelabs/genode/issues/1000#issuecomment-161260312 I hope that you find my line of thoughts reasonable. If you have ideas or thoughts to add, please don't hesitate to share them. Cheers Norman -- Dr.-Ing.

Announcement: Genode OS Framework version 15.11 released
by Christian Helmuth 30 Nov '15

30 Nov '15

The current release focuses on Genode as a desktop operating system and brings lots of improvements in the whole software stack in this regard. On the lower end, we ported the Intel graphics adapter driver from Linux, which enables the use of multiple displays and dynamically configure the screen resolution and connectors. The way up the stack we added secure copy-paste in form of a clipboard component, which supports configuration of the information flow and counters covert communication. On the top, we extensively improved our GUI implementation, most prominently visible by the ability to change the window decorator on run time. The highlights of version 15.11 are - Desktop OS features - Vastly improved GUI stack - Dynamic audio-mixer settings - Copy and paste between subsystems - New VFS component and VFS improvements - New LOG aggregator - Improved support for dynamic component configurations - VirtualBox support for 64-bit guest OSes - Device drivers - Intel KMS framebuffer driver - Framebuffer driver for Exynos 4 - AHCI for non-NCQ devices - Ability to connect to hidden wireless networks - Platforms - Xilinx Zynq-7000 support, including networking - Improved TrustZone support on USB Armory - Simplified memory management on NOVA - Booting via iPXE over HTTP - New tool for creating preconfigured U-Boot images All improvements of the current release are covered by the release documentation http://genode.org/documentation/release-notes/15.11 Kind regards -- Christian Helmuth Genode Labs http://www.genode-labs.com/ · http://genode.org/ https://twitter.com/GenodeLabs · /ˈdʒiː.nəʊd/ Genode Labs GmbH · Amtsgericht Dresden · HRB 28424 · Sitz Dresden Geschäftsführer: Dr.-Ing.

Virtualbox Memory
by Harm de Vries 30 Nov '15

30 Nov '15

Hello all, I stumbled upon a new problem with the Turmvilla setup (on Nova 64bit). If I give my virtual machine 3600 megabytes of memory or more (in the vbox file, the virtualbox subsystem has plenty) it crashes with the following error: [cli_monitor -> linux -> vbox] c/virtualbox/spec/nova/vcpu.h(502) void Vcpu_handler::_irq_window() [cli_monitor -> linux -> vbox] !!Assertion Failed!! Expression: !res Location : /home/hdv/projects/genode/repos/ports/src/virtualbox/spec/nova/vcpu.h(502) void Vcpu_handler::_irq_window() [cli_monitor -> linux -> vbox] EMT-3 EMT-3 !!Assertion Failed!!

Does anyone know what could be the problem? Sorry for all the spam! Kind regards, Harm

Microkernel Meetup
by Bjoern Doebel 28 Nov '15

28 Nov '15

Hi all, as the last Dresden Microkernel Meetup took place already more than 6 months ago, we surely need to set up a new one! Please chose a date: http://dudle.inf.tu-dresden.de/mks1115/ I am going to pick a location once we settled on a date. (Most likely: Shamrock Irish Pub, but select something else on Mondays...)

Nix port
by Emery Hemingway 25 Nov '15

25 Nov '15

Hello list, This is a notice that I've cleaned up the Nix port and created a branch of the Genode master to test against. I've only managed to drive the toolchain part way to creating component binaries, but for now the problems seem to be in the domain of Noux. The core of the port has been defined, and the frontends are done, which is actually no frontend at all. There is the nix-repl for debugging and everything else can use server/nix, which generates ROMs and file system roots on demand. I have a branch 'nix' at https://github.com/ehmry/genode.git with a set of patches against master and an external repo at https://github.com/ehmry/genode-nix.git. The run scenarios 'nix_rom' and 'nix_fs' show how to setup routing to create ROM and file system roots on demand (but poor examples of Nix expressions). The scenario 'nix_toolchain' attempts to build binaries on demand, but I think I need to poke around in Noux to get it to run to completion. I have some examples for generating cli_monitor configurations, though I need to put together a full scenario to show how to route cli_monitor to make it work. https://github.com/ehmry/genode-nix/blob/master/expr/cli_monitor.nix The issue of fetching compiled packages to a live system is still outstanding, I have some ideas on the network protocol, but none on a binary signing scheme. I started on some write-up of the porting process but it will probably be more for people coming from NixOS than from Genode or those interested in making the language more cross-platform. Ignore the name, I'm not a very good writer. http://ehmry.github.io/ Cheers, Emery

SMP IRQ Affinity in L4android
by li94575 25 Nov '15

25 Nov '15

Hi, everyone I want to move some interrupts to specified cpu core, but I encountered some difficulties. When I try to write to "/proc/irq/*/smp_affinity" with cpu bitmask, it will call the interface l4lx_irq_dev_set_affinity(), which locates in "pots-foc/src/lib/l4lx/l4lx_irq.cc". And I can see the printed log "switched irq * to cpu* ". However, in fact, it doesnot work, the irq is still staying on previous cpu core ( seeing "/proc/interrupts") . Please tell me how can I do, thank you so much!
