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.

Session object pool
by Александр Домо 08 Dec '11

08 Dec '11

Hello! I'm writing a server application which acts as a communicator between it's clients. Each of my sessions needs to know about other active sessions, so what I'd like to know is if there is a way to access the session object pool directly, or should I maintain my own list of running sessions? Also, a question about "doing it the right way". I transfer data chunks (not more than several Kbytes) to/from clients using RPC calls (initiated by clients), and I use Signal_transmitter objects to notify clients about data & other stuff. Is that normal? ;) Thanks! A.D.

Announcement: Genode OS Framework version 11.11 released
by Norman Feske 29 Nov '11

29 Nov '11

I am very happy to announce the release of Genode version 11.11. With this version, we explored various opportunities to combine the Genode architecture with virtualization techniques. The topics range from enabling faithful virtualization of x86 PC hardware, over paravirtualized Android, to our custom OS-level and application-level virtualization approaches. The work on these topics materialized in the form of many improvements of the framework. To name a few, the new version features the GDB debugging facility as announced earlier on this mailing list, the integration of the Vancouver virtual machine monitor, the support of running Android based on the work of the L4Android project, and the new ability to execute complex command-line based UNIX software (i.e., VIM) natively on Genode. For regular developers, our new free-standing tool chain significantly improves the situation when developing for different architectures. In particular, this new tool chain alleviates the need for using CodeSourcery tools for ARM and enables the targeting of both x86_32 and x86_64 with a single compiler. The release-notes summary is: * Support for user-level debugging via GDB * Applications and services * Vancouver virtual machine monitor on NOVA * VIM executed on the Noux runtime environment * Terminal emulator implementing the Linux termcap * TCP terminal * Platforms * Fiasco.OC updated to rev 38 * NOVA updated to version 0.4 * New IPC implementation for Linux * Improved support for hybrid Linux/Genode programs * L4Linux on Fiasco.OC * Integration of L4Android (for both x86_32 and ARM) * Stub drivers for block devices, NIC, UART * Device drivers * gPXE device driver environment upgraded to iPXE * Bidirectional UART driver for PL011 and i8250 * PL110 display driver * Support for ARM Versatile Express Cortex-A9x4 * Libc update to FreeBSD 8.2.0 * New unified tool chain based on GCC 4.6.1 As usual, you will find a more elaborative discussion of those topics in our comprehensive release-notes document for version 11.11: http://genode.org/documentation/release-notes/11.11 Have fun with exploring the new version!

22 Nov '11

FOSDEM 2012 - Multiserver, microkernel-based operating systems devroom *CALL FOR PARTICIPATION* http://fosdem.org/2012 (apologies for cross-posting) The developers of several free and open-source multiserver and/or microkernel-based operating systems will meet at FOSDEM 2012 in Brussels, Belgium and will share a developer room. The devroom is currently looking for content in the form of talks related to the area of multiserver and/or microkernel-based operating systems. Possible topics include, but are not limited to: OS introduction to developers of other OS Subsystems and architecture Hardware and device drivers Tools and languages Release engineering and testing Experience and learning from mistakes Technical challenges Community and life with an OS-project Academia and education Please send your talk proposal(s) to: microkernel-devroom@...86... no later than by 2011-12-31. Make sure to include the following in your proposal: - title of your talk (will be printed in the FOSDEM booklet) - your full name (will be printed in the FOSDEM booklet) - your short bio giving us some idea of who you are and what is your relation to and qualification for the subject of your talk - number of 15-minute slots that you need for the talk (talks longer than 45 minutes are discouraged) The final devroom schedule (along with accepted talks) will be announced on 2012-01-9 (Jan 9) in: microkernel-devroom@...86... and the speakers will be notified via e-mail. The schedule will be also published on the FOSDEM web and in the FOSDEM booklet after 2012-01-21. If you do not want to or cannot give a talk yourself, you may still send suggestions for what else you would like to see/hear/do in the devroom. Please send your suggestions to the above mailing list. The devroom is scheduled for Sunday of February 5, room K.3.201. The seating capacity of the room is 85 seats. Any changes will be announced in the above mailing list. Jakub Jermar

Fwd: Multiserver, microkernel-based operating systems devroom at FOSDEM 2012
by Norman Feske 11 Nov '11

11 Nov '11

Hello, I am happy to announce that Genode will participate in FOSDEM 2012 next February. Thanks a lot to Jakub Jermar of the HelenOS project for having invited us to a devroom specifically allocated for microkernel-based and multi-server operating systems such as ours. Please feel hearty invited to join us at FOSDEM and to discuss the planning of the event at the mailing list mentioned in Jakub's official announcement (see below). Cheers Norman -------- Original Message -------- Subject: Multiserver, microkernel-based operating systems devroom at FOSDEM 2012 Date: Fri, 11 Nov 2011 16:57:17 +0100 From: Jakub Jermar The multiserver, microkernel-based operating systems are going to have a dedicated devroom at FOSDEM [0] 2012. The event will take place in Brussels during the weekend of February 4 and 5, 2012. The projects that originally declared interest in the devroom are: GNU Hurd[1] MINIX 3[2] HelenOS[3] Genode[4] If we can get support in the form of devroom content of other related projects, that would make the whole devroom even more worthwile. The reason of having a devroom for interested multiserver and microkernel projects is basically to increase awareness of each other, socialize, talk about the technical problems that our projects have in common and perhaps code together. Or anything else that we can do together. The planning for the devroom is still taking off, but I've already created a mailing list[5]. You are encouraged to subscribe to this mailing list if you would like to participate in the devroom or just come by and say hello to us at FOSDEM 2012. I will send further instructions to that list once the devroom is ready to accept offers of content (e.g. sessions, talks, demos etc.).

See you in microkernel-devroom@...84... Jakub
