Genode Clarification Please
by Lonnie Cumberland 26 Dec '13

26 Dec '13

Greetings All, I am new to Genode and think that it is very nice solution for a microkernel OS for which I am trying to learn more about as it evolves into a fully fledged general operating system as I think that it has the potential to be much better than the majority that are currently available although it still seem to be a long ways from production quality at the moment. One thing that I am not clear about, and please forgive this question if it is a bit elementary as to something simple that I should have been able to ascertain, but I am confused on exactly where the Genode OS framework fall into place as an independent OS. The basis of my question is from the reading that I have been doing on the Genode website in which I can see that it can be compiled to run on baremetal as you would expect an OS to do, but why is it als able to be compiled to be used with other base platforms? I can understand why it might be used with NOVA, which is a microhypervisor and thus Genode could run as a user-land OS in a VM, but I do not see why Genode would need to be compiled against the other base-platforms like Linux, Fiasco, .... Can someone please clarify this for me? Kind Regards and have a great day my friends, Lonnie < CONFIDENTIALITY NOTICE > The information contained in this communication is confidential and is intended only for the use of the recipient named above, and may be legally privileged and exempt from disclosure under applicable law.

Re: Porting on i.MX6
by Aditya Kousik 23 Dec '13

23 Dec '13

Hello Firstly, thank you for patiently replying to our queries and debugging issues so far. We're trying to port Genode onto an i.MX6, which we've realised is no easy task. Our initial approach to this was to tweak existing i.Mx53 files and make corresponding changes (arm cortex a9, created imx6 related folders in include). As pointed out to us by Stefan, this was completely off track as the memory layout may be mixed up (or many more issues). Here's a brief reboot of our attempt: 1. edit create_builddir to add a rule for imx6 board and added build.conf.hw_imx6 in builddir folder. 2. modify board_base.h in base/include/platform/imx6/drivers and fill with addresses by referring to the imx6 reference manual. (We also added CORTEX_A9_CLOCK and private memory base) 3. read through the Makefile and added spec-hw_imx6 and spec-platform_imx6 respectively. 4. created imx6 folder with files in os/include/platform/imx6 as well. (All with imx53 as reference) Make: Since the drivers for imx6 would take a long time to code, we are NOT running demo.run. We tried to build hello.run (without building drivers/timer) according the instructions given in your site. We're getting the following error: Program core/imx6/core COMPILE _main.o ASSEMBLE boot_modules.o COMPILE console.o COMPILE context_area.o COMPILE cpu_session_component.o COMPILE cpu_session_support.o ASSEMBLE crt0.o COMPILE dataspace_component.o COMPILE dump_alloc.o COMPILE io_mem_session_component.o COMPILE io_mem_session_support.o COMPILE irq_session_component.o COMPILE kernel.o COMPILE kernel_support.o COMPILE main.o make[3]: *** No rule to make target `mode_transition.o', needed by `core'.

Respected, I have tried building the file inside genode-13.08 but was not able to build it. I have installed all necessary files. I am getting this error- /usr/local/genode-gcc/bin/genode-x86-ar: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory make[2]: *** [platform.lib.a] Error 127 make[1]: *** [platform.lib] Error 2 make: *** [gen_deps_and_build_targets] Error 2 How should I rectify this error? Thank you! Bulusu.

A20-OLinuXino-MICRO-4GB
by buzz heavyyear 18 Dec '13

18 Dec '13

Hi I have just received a new board with a dual core cortex a7, the A20-OLinuXino, which I'd like to set up and add to the genode tree - currently more pressing than the RPi! I'm no Arm expert, but I'm assuming that I can take most of the existing arm_v7 and a9 code in base-hw and just use this for setting up an a20olinuxino environment and building an image? https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXino-MICRO-4GB/open-… CheersNick

Re: Fwd: Ask for help: The new Valgrind ported to the Fiasco.OC and L4Re
by Björn Döbel 18 Dec '13

18 Dec '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Jian, (cc'ing genode-main as they might be interested in this discussion). as pointed out in the email you forwarded, Valgrind is part of the public L4Re release, which can be found at https://os.inf.tu-dresden.de/L4Re/ The website also includes build instructions. The porting effort mentioned in our paper is mainly because Valgrind intercepts system calls and performs its own resource management. This is implemented for Linux and we had to adapt this to run Valgrind on L4Re. If you wanted to do the same thing for Genode, you'd probably have to make the same adjustments fot that system. As Genode runs on many different microkernels, I am afraid that your port would not be Genode-specific, but specific for a certain (Genode+microkernel) combination. But I'd like to hear the oppinion of Genode people with respect to that. Further, note that the L4Re Valgrind port has last been updated around 2 years ago. If you start your own project, I would strongly recommend to start with a recent Valgrind version (from http://valgrind.org). You could probably still use the L4Re port to figure out which parts of Valgrind you need to touch (it's mainly coregrind).

Re: Genode Clarification Please

Hi, my take on it: Genode is an operating system _based_ on microkernels. Just as Linux is not the operating system, but rather the kernel which then gets supplemented by user-level applications to form an operating system. Genode provides those services, but does not only support one API, but several ones. In addition to the platforms you mentioned (NOVA, Fiasco, Linux, ...) they developed a small internal kernel to support several ARM systems without the need for an external kernel. I'm sure the maintainers can give you a deeper insight into why this was done. Don't confuse virtualization with the use of an underlying kernel, though. With Genode/NOVA, the microhypervisor actually acts as a microkernel with additional support for running virtual machines with hardware support _within_ Genode. Hope that helps, Cheers Markus On 13 December 2013 14:22, Lonnie Cumberland < lonnie@...218...> wrote: > Greetings All, > > I am new to Genode and think that it is very nice solution for a > microkernel OS for which I am trying to learn more about as it evolves into > a fully fledged general operating system as I think that it has the > potential to be much better than the majority that are currently available > although it still seem to be a long ways from production quality at the > moment. > > One thing that I am not clear about, and please forgive this question if > it is a bit elementary as to something simple that I should have been able > to ascertain, but I am confused on exactly where the Genode OS framework > fall into place as an independent OS. > > The basis of my question is from the reading that I have been doing on the > Genode website in which I can see that it can be compiled to run on > baremetal as you would expect an OS to do, but why is it als able to be > compiled to be used with other base platforms? > > I can understand why it might be used with NOVA, which is a > microhypervisor and thus Genode could run as a user-land OS in a VM, but I > do not see why Genode would need to be compiled against the other > base-platforms like Linux, Fiasco, .... > > Can someone please clarify this for me? > > Kind Regards and have a great day my friends, > Lonnie > > < CONFIDENTIALITY NOTICE > The information contained in this communication > is confidential and is intended only for the use of the recipient named > above, and may be legally privileged and exempt from disclosure under > applicable law.

Cannot find dynamic linker binary.
by Edgar Klerks 10 Dec '13

10 Dec '13

Hi List, I am trying to add some libraries in my build.conf: LIBS = base libm But it doesn't seem to load. The error message I get is: [init] Could not open file "ld.lib.so" [init] Dynamically linked file found, but no dynamic linker binary present [init] unknown exception? [init] Dynamically linked file found, but no dynamic linker binary present [init] unknown exception? I am using the nova_x86_32 kernel, but on other kernels this also happens. If I remove libm my image works again. I haven't found anything to build a dynamic linker in the source. Steps I did: create build dir. add libports to etc/build.conf add my source repository to the build dir make prepare PKG=libc && make prepare PKG=stdcxx make run/something The run script starts up qemu. The kernel boots. And then in qemu it cannot find a linker binary. How should I add libraries to my project? I am probably missing some stupid step. Greets, Edgar Klerks

13.11 LiveCD?
by Lonnie Cumberland 09 Dec '13

09 Dec '13

Greetings All, I am new to the GENODE mailing list and am very excited about what I have seen thus far in the project. I am wondering if there is a LiveCD for the latest 13.11 version as the older 2010 version did not work well on my hardware as it would boot up and then after I made a selection it would freeze. I have a HP-Pavilion P7-1451PC 64-bit machine. Kind Regards and have a great day my friend, Lonnie T.

Build system wipes include directory
by Edgar Klerks 08 Dec '13

08 Dec '13

Dear List, I am experimenting with genode and till now it went pretty good. I was building my project and had to rebuilt it a couple of times and suddenly the built broke. I thought no problem, thus I did a make clean. This wasn't helpful. Then I did a make cleanall, but now it wiped out the whole build/include directory. Is this intended behaviour or should I not put things there? At this stage it is just annoying, but I think this is a bug, because the tutorial puts the headers, which define the RPC interfaces. Can I prevent this behaviour? And I want to use c++ features like Strings instead of char *. How can I enable this? I recognize I need a library for this, but I can't find it in base. Thanks for your help! Greets, Edgar Klerks
