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).

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.

Android on top of Genode
by Stefan Kalkowski 23 Sep '11

23 Sep '11

Dear Genode Community, I'm happy to announce Genode's new facility to drive Google's Android. By porting our changes of L4Linux to the L4Android fork we paved the way to run Android instances in Genode. Beside the support of L4Android, we added a bunch of new virtual drivers for L4Linux + L4Android, that enable the usage of the following Genode device driver interfaces in these para-virtualized Linux clones: * Nic-session * Block-session * Terminal-session The new features are available at our SVN repository. For giving it a quick try, you may have a look at the quickstart section in the updated 'ports-foc/README' document: http://genode.svn.sourceforge.net/viewvc/genode/trunk/ports-foc/README Please be aware that currently we've tested L4Android/Genode on top of the IA32 architecture only. Thanks a lot to Adam Lackorzynski as the main author of L4Linux, and to the whole team around L4Android, as well as to Daniel Waddington for bringing this feature onto our agenda.

Error when tried to build manually Hello Demo
by Le Bao TRUONG 22 Sep '11

22 Sep '11

Hi all, I would like build manually the 'Hello Tutorial' demo. But I have an error to execute ./core. I follow the tutorial : 1. Build the server side by make hello/server 2. Build the client side by make drivers/timer make hello/client Then, the tutoriel told me to execute a binary ./core. But I couldn't find core file in my bin/ directory so I build it by make core hello/client Then I execute ./core, my program is stopping at int main(): --- create local services --- int main(): --- start init --- Could not open file "init" ROM module "init" not present int main(): transferred 79 MB to init Would you like give me some advice ? Thanks, Le Bao

User-level debugging on Genode via GDB
by Norman Feske 19 Sep '11

19 Sep '11

Hello, I am happy to announce the addition of a new user-level debugging facility to Genode, which will hopefully make the life of Genode application developers much easier. Our new GDB monitor component allows GDB to be connected to an individual Genode process as a remote target (via UART or TCP connection). Thereby, a wide range of convenient debugging features become available, for example * The use of breakpoints, * Single-stepping through assembly instructions or at function level, * Source-level debugging, * Printing of backtraces and call-frame inspection, and * Observing different threads of a Genode process I want to highlight that both statically linked programs as well as programs that use shared libraries are supported, which we see as a significant improvements over the traditional debugging tools. The new feature is available at our SVN repository. For giving it a quick try, you may find the following documentation useful. Among the introduction of the approach, it provides a step-by-step guide as a starting point for experimentation: http://genode.org/documentation/developer-resources/gdb Please note that, at this point, the feature is only supported on a small subset of Genode's base platforms (namely Fiasco.OC and partially OKL4). We may extend the support to other platforms if we see public demand. Thanks a lot to Daniel Waddington for bringing this feature onto our agenda. Have fun! Norman -- Dr.-Ing.

Asynchronous Nested Page Fault Handling
by Daniel Waddington 13 Sep '11

13 Sep '11

Hi, I am wondering why Genode uses asynchronous signals to call custom nested page fault-handlers. Can someone explain why? It would seem more sensible to use synchronous IPC for this purpose. Thanks Daniel

Need help for Genode + bare-metal app on Codezero
by Le Bao TRUONG 13 Sep '11

13 Sep '11

Hi all, I tried the graphical Genode on Codezero demo and I have developed the bare-metal applications on Codezero Hypervisor. So I think that it's good idea if I could boot two container. One container contient the graphical Genode and the other contient my bare-metal app, 'Hello Word'. So I modified the liker script in base-codezero/src/platform/genode.ld so I could have two container when the script /tools/create_builddir is executed. I executed first time the command 'make run/demo' on my builddir. It complain very normal the makefile could not find my app. So I create a directoire "Hello_Word" in <my builddire>/kernel/codezero/conts/baremetal/ I retried the command 'made run/demo'I have the error : Building userspace libraries... Building containers... Building the kernel... Building the loader and packing... Building qemu-insight-script... Build complete...
