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...

missing stderr?
by Daniel Waddington 31 Aug '11

Hi, Since upgrading to 11.08 I now get a missing symbol for 'stderr' ; needed by libstdc++.a /usr/local/genode-gcc-x86_32/bin/../lib/gcc/i686-pc-linux-gnu/4.4.5/../../../libstdc++.a(vterminate.o): In function `__gnu_cxx::__verbose_terminate_handler()': /home/dwaddington/svn/genode/tool/gcc_build_x86/i686-pc-linux-gnu/libstdc++-v3/libsupc++/../../../../gcc-4.4.5/libstdc++-v3/libsupc++/vterminate.cc:47: undefined reference to `stderr' /home/dwaddington/svn/genode/tool/gcc_build_x86/i686-pc-linux-gnu/libstdc++-v3/libsupc++/../../../../gcc-4.4.5/libstdc++-v3/libsupc++/vterminate.cc:65: undefined reference to `stderr' /home/dwaddington/svn/genode/tool/gcc_build_x86/i686-pc-linux-gnu/libstdc++-v3/libsupc++/../../../../gcc-4.4.5/libstdc++-v3/libsupc++/vterminate.cc:91: undefined reference to `stderr' I can hack around it by declaring stderr in my main.cc.

Announcement: Genode OS Framework version 11.08 released
by Stefan Kalkowski 17 Aug '11

17 Aug '11

The 11.08 release brings unified workflows for all base platforms with a streamlined tooling support, enhanced documentation, and a new quality-assurance infrastructure as well as some functional additions. With the version 11.08, the framework relieves the burden of using distinct base platforms with Genode by introducing a unified way to download, build, and use each of the kernels with Genode's user-level infrastructure. The new tools empower users of the framework to instantly change the underlying kernel without the need to know the peculiarities of the respective kernels. Using microkernels has never been easier. The second challenge of translating each kernel's specific behaviour to the framework's unified API longs for an automated testing infrastructure that systematically exercises all the various facets of the API on all base platforms. The new version introduces the tooling support especially designed for conducting such quality-assurance measures. Speaking of functional enhancements, the work on version 11.08 was focused on our block-device infrastructure and ARM support. The additions comprise new drivers for SD-cards, IDE, SATA, USB storage as well as a new partition server. All those components provide Genode's generic block interface, which is meant to be used a back end for file systems. On file-system level, a new libc plugin utilizes libffat to enable the straight-forward use of VFAT partitions by libc-using programs. Additionally, the release brings far-reaching improvements with respect to ARM-based platforms. The paravirtualized L4Linux kernel has been updated to Linux version 2.6.39 running on both x86_32 and ARM. Also, Qt4 including Webkit has become functional on ARMv6-based platforms. Read on about these and all additional changes in more detail in the release notes at http://genode.org/documentation/release-notes/11.08/ -- Stefan Kalkowski Genode Labs http://www.genode-labs.com/ · http://genode.org/ Genode Labs GmbH · Amtsgericht Dresden · HRB 28424 · Sitz Dresden Geschäftsführer: Dr.-Ing.

exception propagation
by Daniel Waddington 12 Aug '11

12 Aug '11

Hi, I'm trying to catch a Region_conflict exception from a call to env()->rm_ression()->attach(...). By putting printfs in the Genode code I see the exception is being thrown in the rm-session-component, but it does not seem to be getting propagated back to the client app. Can someone check the new GENODE_RPC_THROW macro is working correctly? Fiasco.OC x86_32. Thanks Daniel

Third anniversary of the Genode OS Framework
by Norman Feske 28 Jul '11

28 Jul '11

Dear Genode Community, it has been almost three years ago when we published the first version of the Genode OS Framework. Since then, our ongoing commitment and dedication to bring forward this technology has proven our project to be sustaining and constantly evolving. Moreover, to our delight, the last year has shown that the potential behind our project receives increasing recognition by people outside the inner circle of the Genode and L4 communities. This gives us more than enough reasons to celebrate the 3rd anniversary of Genode together with you! Let's gather for a barbecue and a campfire on 19th of August, 6 pm near Moritzburger Str. 1 in Dresden http://maps.google.de/maps/ms?ie=UTF8&msa=0&msid=103318122554571178078.0004… We'd be happy about everyone who feels related to Genode to join us at the wonderful location nearby the river, enjoying both vegetarian and non-vegetarian barbecue and beverages. If you plan to attend, please leave a short note until 17th of August at info@...1... Cheers Norman -- Dr.-Ing.

gmp on Genode + Fiasco.OC
by Sivaramakrishnan KC 27 Jul '11

Hi, While using gmp library (from libports) in a c project works fine, including gmp in a c++ project throws the following compiler errors. Any insight on what could be going wrong here? Program app/src/test-ml COMPILE main.o In file included from /home/kc/install/omnios/genode/ml/src/app/src/main.cc:1: /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:24:70: warning: iosfwd: No such file or directory /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:25:18: warning: cstdio: No such file or directory /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:51:40: warning: cstddef: No such file or directory In file included from /home/kc/install/omnios/genode/ml/src/app/src/main.cc:1: /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:538: error: 'std::FILE' has not been declared /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:542: error: expected ',' or '...' before '(' token /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:547: error: expected ',' or '...' before '(' token /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:624: error: 'size_t' has not been declared In file included from /home/kc/install/omnios/genode/ml/src/app/src/main.cc:1: /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:807: error: 'size_t' has not been declared /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:807: error: 'size_t' has not been declared /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:807: error: 'size_t' has not been declared /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:904: error: 'size_t' has not been declared /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:904: error: 'size_t' has not been declared /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:904: error: 'size_t' has not been declared /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:1092: error: 'size_t' does not name a type /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:1096: error: 'size_t' does not name a type /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:1353: error: 'size_t' has not been declared /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:1444: error: 'size_t' does not name a type /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:1533: error: 'size_t' does not name a type /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:1590: error: 'size_t' has not been declared /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:1790: error: 'size_t' does not name a type /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:2180: error: expected constructor, destructor, or type conversion before '&' token /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:2181: error: expected constructor, destructor, or type conversion before '&' token /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:2182: error: expected constructor, destructor, or type conversion before '&' token /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:2183: error: expected constructor, destructor, or type conversion before '&' token /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:2184: error: expected constructor, destructor, or type conversion before '&' token /home/kc/install/omnios/genode/libports/include/gmp/x86_32/gmp.h:2185: error: expected constructor, destructor, or type conversion before '&' token make[2]: *** [main.o] Error 1 make[1]: *** [test-ml.prg] Error 2 make: *** [gen_deps_and_build_targets] Error 2 Thanks kc
