Increasing guest memory in Vancouver
by Markus Partheymueller 04 Sep '12

04 Sep '12

Hi, I'm playing around with vancouver and genode a little and stumbled across the problem that there is only 32 MiB hard-wired backing memory. Trying to increase that memory lead to weird errors. Are there any special things to take care of when increasing that memory amount? Regards Markus

Has anyone had success with GCC SVN/4.7
by Taru Karttunen 04 Sep '12

04 Sep '12

Hello I was hacking around gccgo (go implementation in gcc) and I can get the runtime and the compiler compiled when using gcc-4.7-RC-20120314. But the issue becomes rest of Genode not liking a newer gcc. Has anyone else had success with either GCC 4.7 or a SVN version of GCC? My current issue is: Library libc MERGE libc.lib.so fd_alloc.o: In function `Libc::file_descriptor_allocator()': /home/taruti/genohack/genode/libports/src/lib/libc/fd_alloc.cc:26: undefined reference to `__dso_handle' /usr/local/genode-gcc/bin/genode-x86-ld: fd_alloc.o: relocation R_X86_64_PC32 against undefined hidden symbol `__dso_handle' can not be used when making a shared object Has anyone got an idea how to solve this? ps. if someone is trying this, one has to compile libsupc++ explicitely with -fPIC to get cxx working. - Taru Karttunen

Qt port based on QPA
by Robert Campbell 03 Sep '12

03 Sep '12

Qt platform abstraction layer provides a simpler and easier to maintain method of porting Qt to other platforms. Are there plans to upgrade the current Qt port in Genode to make use of the Qt platform abstraction layer?

Porting base-hw to i.mx53
by Timur 31 Aug '12

31 Aug '12

I want to add support of i.mx53 to base-hw. I encounter a problem while turning on MMU. Problem appears when i want to write a system control register with setted mmu bit in enable_mmu function : Sctlr::access_t sctlr = Sctlr::read(); Sctlr::M::set(sctlr); Sctlr::I::clear(sctlr); Sctlr::C::clear(sctlr); -->Sctlr::write(sctlr); after this string system freezes. Registers which are used in this function are the same as in Cortex A9. -- Galiullin Timur

building nova

Hi I built the Nova base at least a year ago and had no problems building using <genode>/base-nova/docs/nova.txt. This time (with !make kernel no longer available) I do a !make and get the following: checking library dependencies...Skip target core because it requires linuxSkip library syscall because it requires linuxSkip library ipc because it requires linuxSkip library rpath because it requires linuxSkip library thread because it requires linuxSkip library startup because it requires linuxSkip target test/ada because it requires gnatSkip target test/rm_nested because it requires experimental Library platform MERGE platform.lib.a Library slab COMPILE slab.o MERGE slab.lib.a Library avl_tree COMPILE avl_tree.o MERGE avl_tree.lib.a Library allocator_avl COMPILE allocator_avl.o MERGE allocator_avl.lib.a Library cap_copy COMPILE cap_copy.o MERGE cap_copy.lib.a Library console COMPILE console.o MERGE console.lib.a Library cxx COMPILE exception.o COMPILE guard.o COMPILE malloc_free.o COMPILE misc.o COMPILE new_delete.o COMPILE unwind.o MERGE supc++.o CONVERT supc++.o MERGE cxx.lib.amake[1]: *** No rule to make target `syscall.lib', needed by `core_printf.lib'. Stop.make: *** [gen_deps_and_build_targets] Error 2 Could someone please give me a hint at what I should do here - I'm running on Ubuntu 12.04 32bit - the prebuilt toolchain seems to work OK.

Midsummer - there couldn't be a better time for releasing a new version of Genode. Among the highlights of version 12.08 are a new base platform that enables the framework to run on bare ARM hardware without a separate kernel, the largely reworked support for the NOVA hypervisor, and comprehensive device drivers for OMAP4-based hardware platforms. Quick overview of the changes that come with version 12.08: - Base platforms - New base-hw platform for running the framework on bare ARM hardware - NOVA support for x86_64, object integrity protection, core-only kernel-resource allocation - New OMAP4 SoC device drivers - HDMI output - SD-card - USB HID - Networking - New FFAT-based file-system service - New TAR file-system service - Improved Noux runtime - New port of the Lynx web browser - Shell scripting support - 3rd-party libraries - New ports of openssl, pcre, expat - MPC, libgmp for x86_64 and ARM - lwIP updated to version 1.4.1-rc1 - New port of the lighttpd web server Those and many more improvements are described in full detail in the release notes: http://genode.org/documentation/release-notes/12.08 Have fun with exploring the new version!

Celebrate the 4th Anniversary of Genode with us
by Norman Feske 22 Aug '12

22 Aug '12

Hello, I just sent out an invitation with the Genode-Labs newsletter today. Just in case you are not receiving these mailings, please find the invitation text below: ---- when we released the first version of the Genode OS Framework four years ago, a few people recognized the potential of the technology but considered Genode largely as a research endeavor, which was probably right at that time. Now, four years of dedication and 16 releases later, Genode has evolved to a comprehensive and useful framework that increasingly captures the interest of the "real world". Over the course of the last year, we learned about several industrial research organizations who picked up our work to build upon, received inquiries about licensing our technology for the use in products, and observed increased public interest in the prospects Genode promises with regard to privacy and security. The most significant event for the project during the past year, however, was our move to liberate its development process and thereby expose our way of working and all technical discussions to the public. Although this was a radical move for a small company as ours, we got immediately rewarded by new developers and users entering the scene and an emerging community spirit. To celebrate these achievements together with us, we would like to welcome you to join us having a barbecue and campfire at the riverside: Google Maps: http://goo.gl/maps/C0luj 23th of August, 6 pm near Moritzburger Str. 1 in Dresden Everyone who feels attached to Genode in some way to another, please do not hesitate to drop by, hang out with the Genode crowd, and enjoy the barbecue and beverages. If you plan to attend, please send a brief notice until 20th of August to info@...1... Cheers Norman -- Dr.-Ing.

Illegal session request to service CPU
by Markus Partheymueller 17 Aug '12

17 Aug '12

Hi, with the latest code in staging I get the following error when starting the PCI driver through ACPI: [init -> acpi -> pci_drv] PCI driver started [init -> acpi] pci_drv: illegal session request of service "CPU" Later, the PCI driver fails because of this. The config portion looks as follows: <parent-provides> <service name="ROM"/> <service name="RAM"/> <service name="IRQ"/> <service name="IO_MEM"/> <service name="IO_PORT"/> <service name="CAP"/> <service name="PD"/> <service name="RM"/> <service name="CPU"/> <service name="LOG"/> <service name="SIGNAL"/> </parent-provides> ... <start name="acpi"> <resource name="RAM" quantum="32M"/> <binary name="acpi_drv"/> <provides> <service name="PCI"/> <service name="IRQ"/> <service name="CPU"/> </provides> <parent-provides> <service name="CPU"/> </parent-provides> <route> <service name="PCI"> <any-child/> </service> <any-service><parent/><any-child/></any-service> </route> </start> The parent-provides entry and the service name="CPU" in <provides> were not present in my last setup, but didn't change anything. Am I missing something or is there a problem with the most recent changes regarding the CPU session or NOVA-specific code? Cheers, Markus
