Hi, Is it possible to use the standard C++ template library? or is this not ported to the Genode runtime? Thanks Daniel

Equivalent to ucontext APIs
by Daniel Waddington 08 Mar '11

08 Mar '11

Hi, I want to perform user-level scheduling in Genode. Previously we used the POSIX ucontext APIs to save the thread's state, create a new context, and swap between contexts. Before I try to put the equivalent in place in Genode, I am wondering if there are any existing facilities to do this sort of thing in user-space. Also any advice on approach is welcome. Thanks Daniel

Libports building problem with Genode 11.02 + Fiasco.OC
by Daniel Waddington - SISA 02 Mar '11

02 Mar '11

Hello, We're struggling to build Genode 11.02 + Fiasco.OC on x86. We are building using the genode GCC x86-ia32 binaries (gcc 4.4.5) running on a x86_64 Ubuntu box. When we add "libports" to the REPOSITORY we get: COMPILE readlink.o COMPILE rlimit.o COMPILE select.o COMPILE strcoll.o COMPILE strxfrm.o COMPILE sysctl.o COMPILE wcscoll.o COMPILE wcsxfrm.o MERGE libc.lib.so genode-x86-ld: /home/dwaddington/git/omnios/build/genode/var/libcache/cap_alloc/cap_all oc.lib.a(cap_sel_alloc.o): relocation R_386_GOTOFF against undefined symbol `__l4sys_invoke_indirect' can not be used when making a shared object genode-x86-ld: final link failed: Bad value make[2]: *** [libc.lib.so] Error 1 make[1]: *** [libc.lib] Error 2 make: *** [gen_deps_and_build_targets] Error 2 I have no idea how to fix this. Any clues? Thanks Daniel

SMP ia32 support with Pistachio
by Daniel Waddington - SISA 01 Mar '11

01 Mar '11

Hi, Has anyone managed to get Pistachio+Genode with SMP+ia32 running? We have managed to get Pistachio+Genode+ia32 without SMP working fine. As soon as we compile SMP it goes into an endless loop. Any ideas? Thanks Daniel Waddington

Announcement: Genode OS Framework version 11.02 released
by Norman Feske 24 Feb '11

24 Feb '11

We are happy to announce the release of the version 11.02 of the Genode OS Framework. The development is this version was primarily focused on further expanding the platform support of the framework. We are excited about the following three significant improvements in this area. First, we introduced support for the Fiasco.OC kernel, which is a modern capability-based microkernel developed at the Dresden University of Technology and published under GPLv2. Fiasco.OC provides a rich set of features, most notably kernel support for user-level object capabilities (hence the suffix "OC"), multi-processor support, and comprehensive support for the x86_32, x86_64, and ARM architectures. For more information on Fiasco.OC visit http://os.inf.tu-dresden.de/fiasco Second, we upgraded the support for the NOVA hypervisor to version 0.3, and thereby, promoted the NOVA version of Genode to cover the entire Genode API. So, NOVA can now be recommended as base platform for Genode without reservations. The project website of NOVA is: http://hypervisor.org Third, the Genode project reaches out to kernel land by adding a custom kernel platform for running Genode on the Xilinx MicroBlaze CPU architecture. Our design has a special twist that sets it apart from existing microkernels, namely that it is not a free-standing program but a part of Genode's core. By consolidating the kernel with the user-level core into one program, the TCB complexity of the Genode base systems gets quite dramatically reduced compared to the combination of a normal microkernel with core running as roottask. The most prominent functional addition introduced with the new release, is the Noux execution environment, which facilitates the use of GNU userland software on top of Genode without requiring much manual porting labour. Albeit being in an early stage, Noux is already able to run many commands of the GNU coreutils. In short, the release notes summary is: - Fiasco.OC as new base platform - Running Genode natively on MicroBlaze CPUs - Support for version 0.3 of the NOVA hypervisor - Noux execution environment for GNU userland software - Base framework - Core resource accounting using guarded allocators - Protocol enhancements for upgrading session quotas - Qt4 updated to version 4.7.1 - New tool for automated integration and testing Please find a more elaborative description of the changes accompanied with a lot of background information in the release notes of version 11.02: http://genode.org/documentation/release-notes/11.02 The new version is ready for download at our download page at Sourceforge and our public SVN repository: http://genode.org/download Best Regards -- Dr.-Ing.

x64 Compatible Tool Chain
by Sam Kerr 13 Jan '11

13 Jan '11

I am trying to work with Genode on Ubuntu 10.10 x64 edition and get the tool-chain set up. However, the tool-chain download is for x86 and I can't see any way to build it for x64. Is it possible to develop Genode on 64 bit Ubuntu, or do I simply need to use 32 bit instead? Thanks!

Genode Live CD 10.11 released
by Stefan Kalkowski 16 Nov '10

16 Nov '10

The Genode project proudly presents a bootable live CD representing the current state of the Genode OS Framework. Features like running Linux as browser plugin, 3D hardware acceleration, sound support, and a complete networking infrastructure are incorporated to form a single coherent setup. The live CD boots in less than 10 seconds (on VirtualBox) into a a fully functional GUI with a selection of five demo subsystems. Each subsystem highlights a different aspect of the framework. A paravirtualized Linux, seamlessly integrated into Genode's native Nitpicker GUI, can be found right next to native Qt4/Webkit applications. The port of the Arora web browser stands out for featuring a plugin that can execute arbitrary Genode subsystems in a secure way. This tech demo features multiple browser-embedded application including a complete Linux system, streaming a disk image live over HTTP from a web server. Another subsystem runs the famous gears OpenGL demo via the native port of Gallium3D/Mesa, offering hardware support on Intel GMA GPUs. Furthermore the CD executes a range of new drivers and features not present in the last releases. As kernel OKL4 v2 was chosen.
