PicoTCP (an alternative to IwIP?)
by Paul Dufresne 14 Mar '14

14 Mar '14

Well, I just watched this video from FOSDEM 2014, and it made me think about Genode. http://video.fosdem.org/2014/AW1121/Sunday/PicoTCP.webm or https://www.youtube.com/watch?v=AO4liMJZ0Qg The FOSDEM page: https://fosdem.org/2014/schedule/event/deviot03/ The PicoTCP page on the company web site: http://www.tass.be/en-gb/expertise/connected-devices/picotcp/ which does have a link to the GNU GPL v.2 code: https://github.com/tass-belgium/picotcp I really don't have the knowledge to compare with IwIP, but am pretty sure there is someone here able to evaluate how well it fits with Genode.

OMAP4 Sd card ported to OMAP3
by Bob Stewart 12 Mar '14

12 Mar '14

I'm trying to get SD card support running on a Beaglebone (OMAP3). The sdcard driver from the Pandaboard (OMAP4) implementation should work, as the same MMC hardware is used on both boards. With only changes to the hardware address and the irq to reference one of the mmc instances on the Beaglebone, I successfully detect an SD card and read one block from it. This was done using the content of the /sd_card_bench/ run script. After the successful block read (non-dma), a call is made in the driver to "/complete_packet/" in the session pointed to from the Block driver. This call fails at the call tx_sink()->ready_to_ack() into the session_rpc_object with: /no RM attachment (faulter 802d208c with IP 81009fc4 attempts to read from address 200)// //unknown signal context/. Does this indicate that the rpc object was not set up correctly? Since I'm using the code in the OMAP4 /bench///directory untouched to run this, I would not have expected an issue with the block driver set up. Any advice would be appreciated, as I dig further in the Genode rpc's. Thanks, Bob Stewart

No display for running framebuffer.run
by Aditya Kousik 12 Mar '14

12 Mar '14

Hello I've tried running the test-framebuffer on my linux_x86 base. The terminal log session sends debug message of "blue", "green", "red" etc. But nothing shows on the QEMU monitor. What could be going wrong here? Thanks and regards Aditya

Greetings All, I have just been trying to compile Genode with NOVA and VirtualBox and ran into an error: ----------------------------------------------- MERGE virtualbox-recompiler.lib.a Library virtualbox-runtime COMPILE Runtime/VBox/log-vbox.o COMPILE Runtime/common/alloc/memcache.o ASSEMBLE Runtime/common/asm/ASMAtomicCmpXchgU64.o ASSEMBLE Runtime/common/asm/ASMAtomicReadU64.o ASSEMBLE Runtime/common/asm/ASMAtomicUoReadU64.o ASSEMBLE Runtime/common/asm/ASMAtomicXchgU64.o COMPILE Runtime/common/checksum/md5.o COMPILE Runtime/common/err/RTErrConvertFromErrno.o CONVERT errmsgdata.h COMPILE Runtime/common/err/errmsg.o genode-x86-g++: error: Runtime/common/err/errmsg.cpp: No such file or directory genode-x86-g++: fatal error: no input files compilation terminated. make[2]: *** [Runtime/common/err/errmsg.o] Error 1 make[1]: *** [virtualbox-runtime.lib] Error 2 make: *** [gen_deps_and_build_targets] Error 2 ---------------------------------------------- everything was proceeding well and I had completed all of the "make prepare" requirement and did the "make virtualbox" I have the genode-toolchain-12.11-x86_64.tar.bz2 installed as well on my 64-bit Debian system which is running in VirtualBox on a test system for building as I want to generate an iso to boot into a machine to see how it works. I would like to replicate the genode/nova/virtualbox demo done at FOSDEM to run some simple test OS's. Kind Regards and have a great day, Lonnie

Build errors incorporating libc
by Bob Stewart 03 Mar '14

03 Mar '14

I'm building with 13.11 on an ARM platform. I've done a make prepare in libports for the libc package. The build fails during in the library creation on a "No rule to make target `_setjmp.o' " error --- Snippet of the build log is: . . . Library libc-string Library init_pd_args MERGE libc-string.lib.a Library libc-stdlib MERGE libc-stdlib.lib.a Library libc-locale MERGE libc-locale.lib.a Library libc-stdio MERGE libc-stdio.lib.a Library libc-gen MERGE libc-gen.lib.a Library libc-gdtoa MERGE libc-gdtoa.lib.a Library libc-inet MERGE libc-inet.lib.a Library libc-stdtime MERGE libc-stdtime.lib.a Library libc-regex MERGE libc-regex.lib.a Library libc-compat MERGE libc-compat.lib.a make[3]: *** No rule to make target `_setjmp.o', needed by `libc-setjmp.lib.a'. Stop. make[3]: *** Waiting for unfinished jobs.... Library libc-setjmp make[2]: *** [libc-setjmp.lib] Error 2 make[2]: *** Waiting for unfinished jobs.... Library ldso-startup . . . What am I missing? Thanks, Bob Stewart

Toolchain out of date?
by Guido Witmond 02 Mar '14

02 Mar '14

Dear people of Genode-labs, After a long time lurking, I wanted to give it a spin. These are my experiences: I installed an Ubuntu-12.04-03 iso on a virtual-box vm. I downloaded: genode-14.02.tar.bz2 and genode-toolchain-12.11-x86_64.tar.bz2 Unpacked according to instructions. When trying the make run/demo from the 'getting started' page I get this error: $ make run/demo /bin/bash: /usr/local/genode-gcc/bin/genode-x86-g++: cannot execute binary file and more of these for other binaries from the toolchain, eg gcc, ar, etc. Some investigations: $ file /usr/local/genode-gcc/bin/genode-x86-g++ /usr/local/genode-gcc/bin/genode-x86-g++: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, BuildID[sha1]=0xe8a025bec16cdc16afa6cc41c05e1bdf19a9fbc4, stripped $ ldd /usr/local/genode-gcc/bin/genode-x86-g++ not a dynamic executable $ cat /proc/version Linux version 3.8.0-29-generic (buildd@...232...) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #42~precise1-Ubuntu SMP Wed Aug 14 15:31:16 UTC 2013 Compiling the tool-chain using tool/tool-chain script gave a working compiler and a running demo! I guess, the latest tool-chain 12.11 is out of date for the latest Ubuntu. I hope to post more experiences later on. With regards, Guido Witmond.

Genode System Architecture and Configuration Questions,
by J. M. Becker 28 Feb '14

28 Feb '14

Hi Genode Engineers. I've been following the Genode project for a few years, and I'm very excited about it's progress. I've worked through some of the build instructions, and read most of the documentation on the website. I've been able to test out various run files, and I want to begin porting some stuff. I just have a few questions, which would help me understand how you envision the system level considerations. 1. Do any library level diagrams or flowcharts exist? Specifically to describe at which point various pieces funnel together? Maybe something with details comparable to Linux_Graphics_Stack_2013.svg<http://upload.wikimedia.org/wikipedia/commons/c/c2/Linux_Graphics_Stack_201…> ? 2. How are shared configuration files handled? For example, system level configurations often found in /etc? Thanks Everyone, -J.

Re: Method definitions for session interfaces
by Meenakshi Narayanan 25 Feb '14

25 Feb '14

Hello, As far as the session interfaces are concerned, the framework is very intricately designed (hats off). Connection->Client->Capability->Session. If I want to call a function defined by the session interface, one has to include the <session_name>/connection.h and make a call which then calls the Rpc_functionName. My question is this: Where is the body of such functions defined? Is there a framework that dictates where the body of the function goes? More specifically, this doubt came up when exploring the Attached_io_mem_dataspace which contains a function called dataspace(). Recently, my friend Aditya posted this<http://sourceforge.net/mailarchive/forum.php?thread_name=CANhviG0%3DKY2%3D%…> and it gave the error 'No RM attachment', which is found in the function print_page_fault defined in util.h. My assertion is that a component that uses the MMIO class initlaiised with this dataspace().local_addr() rather than the physical address itself. Long story short, what could have caused this page fault? Thanks in advance, Meenakshi.
