Further questions

Hi, Thanks you very much for that. I now have it running. I have another question about Genode. More specifically, I was wondering whether any of the Iguana services at all. I ask this given that the weaver.xml file refers to memsections and pds (i'm assuming that means protection domains). Peter ----- Forwarded message from Norman Feske <norman.feske@...1...> ----- Date: Tue, 05 Jan 2010 08:43:36 +0100 From: Norman Feske <norman.feske@...1...> Reply-To: Genode OS Framework Mailing List <genode-main(a)lists.sourceforge.net> Subject: Re: Broken assertion To: Genode OS Framework Mailing List <genode-main(a)lists.sourceforge.net> Hi Peter, this is a different error as the one mentioned in the Wiki. It actually tells you what's wrong. ;-) In the 'weaver.xml' file, there is a memsection referring to a file called 'config'. This is the configuration file of Genode's init process. You can use a copy of the template provided at 'os/config/demo'. You can either specify this file as filename for the 'config' module entry in 'weaver.xml' or copy it to your '<builddir>/bin/' directory (and of course rename it to 'config'). This bit was missing in the Wiki. So I added it to the Wiki page. Thank you for pointing it out.

Roadmap 2012
by Norman Feske 02 Jan '12

02 Jan '12

Hello, as the end of the year is approaching, it's time to make up our minds about the focus of the project in 2012. There are numerous directions we may head to, for example, we could advance our ARM support to move towards the mobile space (tablets and smart phones), or put emphasis on multi-processor support and NUMA, new kernel platforms could be explored, or we could bring forward our ambitions to combine Genode with reconfigurable hardware. However, for me personally, the biggest leap would be to start using Genode as everyday platform for my personal computing needs. I am convinced that the framework has reached the maturity and the essential functionality to make this vision come true in 2012. Using our platform for productive work would provide us with the incentive to address real-world problems that matter for actual users - simply because we would be demanding users. Furthermore, there is no better way to show the conviction that we have in our technology than to use it ourself. Therefore, I propose "Eating our own dog food" as the grand theme of our project for the next year. To schedule our road map, we should first become aware of our actual computing needs and then sensibly prioritize those requirements. I'll start with a brief list of software functionalities that I need. Fundamental: * VIM * Shell (e.g., bash) * Tool chain (coreutils, gcc, binutils, make, findutils, tar, Tcl, expect) * Persistent file system * Block-device encryption * SSH client * Git client * GNUPG * Web browser (also used for email, don't need multi-media stuff) * PDF viewer * A way to run a just-compiled Genode sub system * Interactive python shell (to be used as a calculator) * Screen lock * A fall-back virtual machine running Linux for carrying out sporadic work with images (Gimp, Povray, ImageMagick, etc.) and LaTeX, and for testing the Linux version of Genode Of course, there are further things I desire that are not fundamentally important but would make the experience much more enjoyable. Add-ons: * Tiled window manager (similar to the wonderful ion3) * Intel wireless driver * Media player (at least for playing music) * Thinkpad ACPI support, fan daemon * Qemu * Tuxpaint This list is surprisingly short. With Noux already having reached the state where we can execute VIM natively, supporting the other command-line tools will, for the most part, be a matter of enhancing Noux (i.e., adding support for the fork syscall). In addition, I have the immediate goal to release a new live CD by February 2012. Ideally, the demo scenarios featured on the new live CD should give a glimpse on how Genode will be used a general- purpose OS. Do you agree with the proposal of the overall theme for 2012? Which preconditions would you consider as fundamental to make Genode usable for carrying out productive work? Which other direction would you like to see Genode heading to? Cheers Norman -- Dr.-Ing.

02 Jan '12

dear christian helmuth, Here i attached the client-server program used in genodetoolchain. Basically i'm trying to build a client-server program with encryption facilities. But problem i'm facing here is while sending a string from client to server only the first character in the string is received remaining characters were scrambled.please kindly give some suggestion. Thanking you, with regards, B.Pruthiviraj.

some minor suggestions
by ross mcginnis 02 Jan '12

02 Jan '12

Hello all, happy new year! I've been away from the computer for a while and am starting to get back into programming. I'm keen focus on a couple of small personal Genode projects I've wanted to do for a some time. I've a few questions and suggestions to help build the Genode community from the perspective of a hobby programmer like me: 1) could you supply a logo to display on web-pages for linking back to the Genode web-site. 2) As-far-as I can see there is there no place on the Genode site for listing 3rd party associated projects- do you plan in the future to offer something like this? 3) I would like to make a small donation to this project- could you provide a bitcoin address? (It does give one a nice warm fuzzy feeling knowing that you've helped a project that you use) 4) Is it planned for Genode support secure booting and attestation in the future? Secure boot + local object-cap OS + web lends itself to many interesting project possibilies: eg- p2p social networking where the user has true control over their own personal info, or a fast and efficient p2p digital currency, etc. (I believe that there are drivers for the intel TPM chips in Linux--maybe these could help?) thanks ross mcginnis

Hello, if you have a topic in mind that would be worthwhile to present at the microkernel devroom at FOSDEM 2012, please consider submitting your idea (by an informal posting to microkernel-devroom@...86...). It would be great to have a larger variety of contributions.

How to run Genode with L4Linux having only one RS232 port
by e.fedotov 29 Dec '11

29 Dec '11

Hello! I am trying Genode on some different ARM platforms such as: a) Nvidia Tegra 250 (Development Kit board) b) Beagle board (www.beagleboard.org) I have no problem to build and run Genode having FOC kernel support for these boards (working via UART terminal without graphics) But to run L4 Linux the Terminal session is needed, and that session can only be provided via user (not kernel) UART. But there is no possibility to use another UART, other than we have for kernel standard input/output (board b without extentions has only one RS232) So, is there any possibility to use only one terminal connection for kernel and l4linux simultaniously (the same console for input/output)? For example, a stub uart driver that redirects uart IO&interrupts to standard IO? 2) Have you intentions to add any of these ARM platform support in Genode (drivers for uart,display etc.)? The platforms above I think, are more avaliable than pbx-a9. All of the Best and Happy new Year, Evgeny.

Using libports
by Adi Lima 26 Dec '11

26 Dec '11

Hi, I am new to Genode, and still trying to understand how it works. But I've build several test using L4Ka::Pistachio base and of course Linux-based. I've found some very interesting ports while browsing $(GENODE_DIR)/libports, particularly the filesystem and block device related stuffs, because I don't know how to access the harddisk so far, unless using L4Linux with Fiasco.OC. Is there some example for using block_session for a simple client, maybe just to get partition info from a SATA disk? I need a starting point to use these stuffs :-) Thanks. Best regards, FX. J.

Fwd: [Microkernel-devroom] [TALK-PROPOSAL] Introduction of the Genode OS Framework
by Norman Feske 19 Dec '11

19 Dec '11

Hello all, here is my proposal about Genode's participation in the microkernel/multiserver devroom at the upcoming FOSDEM 2012, cross-posted from the microkernel-devroom@...86... mailing list. -------- Original Message -------- Subject: [Microkernel-devroom] [TALK-PROPOSAL] Introduction of the Genode OS Framework Date: Mon, 19 Dec 2011 10:55:50 +0100 From: Norman Feske <norman.feske@...1...> Reply-To: Multiserver, microkernel-based operating systems devroom mailing list. <microkernel-devroom@...86...> To: Multiserver, microkernel-based operating systems devroom mailing list. <microkernel-devroom@...86...> Dear devroom participants, Here is my talk proposal about the Genode project. [Title] Introduction of the Genode OS Framework [Full name] Norman Feske [Short bio] Norman is one of the founders and architects of the Genode project. In 2008, he co-founded Genode Labs - a company with the mission to transform this OS technology from an once obscure research project to a next-generation main-stream OS. [Estimated duration] 45 min [Abstract] Today's operating systems try to find a balance between seemingly conflicting goals. Ease of use is traded against security, resource utilization is traded against resource accountability, and system complexity is traded against scalability. For example, SELinux is ill famed as hard to use and consequently remains widely unused. As another example, isolation kernels minimize the complexity of critical system software but at the cost of limiting these solutions to static applications. The Genode OS architecture shows how these apparently inherent conflicts can be solved by operating-system design. By combining a recursive system structure with capability-based security, mandatory access control becomes easy to deploy. At the same time, the trusted computing base can be minimized for each application individually such that the attack surface for security-critical system functions gets reduced by orders of magnitude compared to existing approaches. Furthermore, a concept for trading physical resources among processes allows for dynamic workloads while maintaining quality of service. That is not just theory - the system is ready for demonstration and its developers are planning to use it as development environment by the end of 2012. After a brief introduction of where Genode comes from, the main part of the talk will be focused on the OS architecture and give a glimpse at the implementation via live demonstrations. Finally, the talk will briefly discuss the planned steps towards using Genode as general-purpose OS. _______________________________________________ Microkernel-devroom mailing list Microkernel-devroom@...86... https://lists.fosdem.org/listinfo/microkernel-devroom
