Current genode release
by Daniel Waddington 06 Jun '11

06 Jun '11

Hi Stefan, We can't compile the latest SVN pull of Genode due to some issues with missing base-foc/contrib/kernel/fiasco. Can you please tell me what the dir structure should be and what it should contain - and check everything is their for the build. Thanks Daniel

Prerequisite mechanism that Genode expects from a new kernel
by Althaf K Backer 02 Jun '11

02 Jun '11

Greeting to Genode Community, i have been following this list for past 1 year, haven't posted any thing yet.I was more of trying to learn genode community :-).Well, now let me come the the point,I'm trying to understand Genode from bottom to top, from the subject i hope you have understood what i meant. Answers to my question does lie in /base-host directory and checking out already implemented base-xxx.However, before i dive into them if you could explain the underlying mechanism that genode expect from a new/fresh dedicated kernel meant to use genode it would help understand the /base-{host,linux,et al} better. Like, threads, shared memory, sockets, paging, MMU support etc.It would be excellent , if we have an article in [1] explaining porting to hypothetical kernel.

Thread creation
by Jaeyeon Kang 30 May '11

30 May '11

Hi, While I am trying to create many threads by using Genode::Thread, I've found that only up to 31 threads could be created. I've got the following message when more than 32 threads is created: C++ runtime: Genode::Cpu_session::Thread_creation_failed. Do you have any idea on this problem? Thanks, Jaeyeon Kang

Announcement: Genode OS Framework version 11.05 released
by Norman Feske 26 May '11

26 May '11

The version 11.05 of the Genode OS Framework has just been published and brings along many new things to explore. Our work on this release was motivated by two main goals, advancing the degree of support for the platforms introduced with the previous release and reconsidering one of the most fundamental base APIs of the framework, namely the inter-process communication API. The traditional IPC and client-server APIs of Genode served us well over the last five years and have never been significantly changed. However, during this time period, we gathered plenty of experience about how those APIs are used in practice and where their limitations lie. Some aspects such as the lack of type safety had been repeatedly criticised whereas other supposedly great features remained largely unused. Now, the right time has come to apply our gathered experience for re-approaching the problem. The result is a brand new RPC API that facilitates type safety and ease of use while sticking to the use of no other tool than the C++ compiler. Because this is the most far- reaching API change in Genode's history so far, the release- notes document (see below) covers our line of thoughts and the migration path of existing software to the new API in great detail. Fiasco.OC as the latest addition to Genode's base platforms has received a lot of attention. We have managed to advance this platform to the same level as other fully-featured platforms, including support for dynamically linked binaries and the signalling API. Furthermore, we are making two of Fiasco.OC's most valued features available to Genode, which are its support for the ARM and x86-64 architectures and the ability to run the paravirtualized L4Linux kernel as user-level process. Also our custom kernel implementation for MicroBlaze-based SoCs has undergone a major upgrade, enabling the implementation of user- level device drivers. To make this platform easy to explore, the release is accompanied with a reference SoC that is ready to use on the Xilinx Spartan3A Starter Kit. With regard to the framework's functionality, the new version features the experimental integration of the GNU debugger with Genode, introduces a number of new device drivers for the ARM RealView PBX platform, and adds new scripts to automatically exercise popular Genode features such as Qt4 and lwIP on different base platforms. The release notes summary is as follows: * New API for type-safe inter-process communication * Extended Fiasco.OC platform support * Shared libraries * Signalling framework * ARM RealView PBX-A9 support * x86 64-bit support * L4Linux (IA32 and ARM) * New experimental GDB support * Device-I/O support for MicroBlaze platform * ARM RealView PBX device drivers for input, display, network, and sdcard * New ready-to-use scripts for easy test-driving of various Genode features such as Qt4, lwIP, Noux, L4Linux, GDB For a detailed discussion of these topics, please refer to the full release-notes document: http://genode.org/documentation/release-notes/11.05/ Best regards -- Dr.-Ing.

hello_tutorial
by unknown＠example.com 25 May '11

25 May '11

Hi, I would like to get working example from "hello_tutorial". Building demo or l4linux leads to making .iso file and next running it from QEMU. But, in case of hello sample (according to "Creating your first Genode Application" manual) we should "... go to build/bin, run ./core, and get excited". I have tried to play with demo and l4linux configs but it doesn't help. Have I missing something or this manual is out of date? Thanks, Yuri Kozyaev

L4Linux for Genode
by unknown＠example.com 25 May '11

25 May '11

Hi, I have tried to go through building process of L4linux for Genode. I have made Demo. It is OK. Next, I have built L4Linux for Genode with initrd.gz from demo CD. But kernel stops with segmentation fault. What is wrong?

Running genode over genode
by Ivan Bludov 21 May '11

21 May '11

Hello, I have an idea to run one Genode-Core over the another Genode-Core just like a simple genode application on a Fiasco.OC. I think it's possible and I have checked this opportunity on host-linux. I think it's interesting idea that provides the new isolation abstraction level of Genode like VM. I think that this idea demands some reducing of platform part of foc functionality. But I don't guess what difficulties it leads for. I don't know enough L4 api. Can you point out some possible problems/changes that have to be solved in order run one genode-core on another? Like changing pager of upper core or some others. Regards, Ivan

Separating native applications and a complete Linux environment on Genode
by Magnus Andersson 18 May '11

18 May '11

Hi I'm looking for a solution for running one or more application (preferably Qt-apps) on a microkernel and along side of those apps running a complete Linux environment. The thing is that the Qt-apps can be trusted (i.e somewhat trusted, since these are built in-house and should not contain any malicious code) and the Linux environment cannot be trusted since this will be open for others to develop application for. My first thought was that I should use a virtualization solution but one of the requirements are that both all apps should be visible on screen, and preferably be able to use hardware accelaration. As I understand you can run both native Qt-apps on the microkernel and also a Linux environment, but how are they separated? if someone manage, lets say, a buffer owerflow in Linux how far down the tree will it reach? Can it break the complete system? And another question, for the live-cd image you fire up a console (maybe Busybox), can you give me any hints on how to make it work or do I need to download it and port it from scratch? Thanks in advance! //Magnus

Genode vs. L4Re
by Nuno Santos 18 May '11

18 May '11

Hi I've just learned about the Genode OS framework, and I'd like to understand how it compares with L4 Runtime Environment (L4Re). I was reading the overview and I got the impression that Genode and L4Re provide very similar functionality. I'm sure I'm missing something. Thank you very much. Best regards, --Nuno Santos

l4Linux problems.

Hi, I am testing the new L4Linux on Fiasco.OC capabilities with the initrd.gz from genode.org/files.
