Problems with virtualbox after commit cdb7904
by Christian Menard 05 Aug '14

05 Aug '14

Hi, I'm trying to tun NOVA(64)+Genode+VMBox+Android on a System with Intel Core i5-4302Y CPU. So far it worked fine, but I got trouble since commit cdb7904 "timer: nova specific version of the service". With this patch applied, Android on VMBox is not booting up anymore. Instead I get messages like this: [ 19.900000] INFO: rcu_preempt self-detected stall on CPU I tried to reproduce the issue in QEMU, but there everything works fine. So the issue seems to be related to my Hardware. In the logs everything looks fine, I couldn't find any abnormalities. Do you have any ideas on what might go wrong or where I should start investigating? Unfortunately my debugging possibilities are limited, as I have no serial connection. Thanks Christian

PicoTCP
by Daniele Lacamera 02 Aug '14

02 Aug '14

Hello, I've stomped onto an old post on this list, considering a port for picoTCP. https://www.mail-archive.com/genode-main%40lists.sourceforge.net/msg01976.h… If I understood correctly, the major concern was around the threading model. We now have a library that provides blocking socket operations in a OS-agnostic way: https://github.com/tass-belgium/picotcp-bsd All you would need to provide is a couple of synchronization mechanisms (- a mutex and a msgqueue/semaphore) in your own -osal module, besides the clock source and the allocator as for any ports in the stack. Feel free to ask for any information, but please keep us in cc since we are not subscribed to the mailing list. Regards, Daniele Lacamera

Configuring Virtualbox
by Christian Menard 31 Jul '14

31 Jul '14

Hi all, is there any way to change the settings of the virtual machine started on Genode? For instance by providing a *.vbox config file? In my special case I would like to activate the usage of absolute mouse events in VMBox so that the usage of a touchscreen becomes more convenient. Greetings Christian

Raspberry Pi not booting kernelimage
by Marcus Nolte 31 Jul '14

31 Jul '14

Hello everyone, I am currently trying to get Genode 14.05 running on the Raspberry Pi. As a first shot, I followed the instructions in the 13.11 releasenotes for compiling the genode-demo for the RPi. However, when trying to boot the genode image, I'm stuck with the colored rainbow splash screen. I simply added the image to an existing (and running) raspian image and modified config.txt. The same happens when I try to run the printf test. - I'm not getting any output over the UART. Am I missing something here? Best regards Marcus -- Marcus Nolte, M. Sc.

Process creation on Fiasco.OC / L4
by Stark, Josef 31 Jul '14

31 Jul '14

Hi all, I am trying to find out how process creation (and termination) is done on the Fiasco.OC/L4 platform. I took a look at cli_monitor and launchpad apps and tried to trace the function calls to fiasco.OC/L4 but I am not very experienced and didn't succeed. If anyone could give me some hints and push me in the right direction, I would appreciate it. (Just to clarify: I am not interested in how to create/terminate processes in genode but rather in how Genode creates (starts) processes on Fiasco.OC, e.g. which Fiasco-Procedures (or L4) get called in order to do so. Thanks in advance! Sincerely, Josef

Kernel Initialization iMx6
by chirag garg 25 Jul '14

25 Jul '14

Hi Stefan, We tried to further to debug call to call as you mentioned . And we find out that the call for *pic( ) in *kernel.cc is reaching to the Grand parent Arm_gic :: Pic constructor. In constructor _distr ( distr_base), _cpu ( cpu_base) are getting initialized, which is working fine. And whenever functions of _distr and _cpu objects are being called, it's got stuck. like in the initialization part *_distr.max_interrupt( ) *is not working. The same thing is working in Genode version 13.11 but not in 14.05. Can you suggest some thing to debug this problem ?? Regards Chirag Garg IIT Madras , Rise Lab

Kernel Initialization Problem
by chirag garg 24 Jul '14

24 Jul '14

Hi As I am working on iMx6 Board. I am trying to use Arm_gic Interrupt Controller instead of TZIC used in iMx53 board. Previously I was using Pic_based:: Pic( ). As the version change in Genode 14.05, Inside : Genode/repos/base-hw/src/core/kernel/kernel.cc we are calling " init_kernel_uniprocessor( ) " to set up the env for other core and then we are calling " init_kernel_multiprocessor( ) " which is using *pic( )* call at various places which is returning a singleton object. extern "C" void init_kernel_multiprocessor() { ..... ..... init_trustzone(*pic( )*); ...... } and the pic( ): Pic * pic() { * return unmanaged_singleton<Pic>( ) *; } and at this point it is not able to return the object *unmanaged_singleton<Pic>( ) , *what could be the problem ?? Regards Chirag Garg IIT Madras , Rise Lab

Kernel Initialized in iMX6
by chirag garg 23 Jul '14

23 Jul '14

Hi all. I am trying to port genode 14.05 on iMX6 board. As Aditya done this successfully for Genode 13.05. But Genode 14.05 is having so many changes from version 13.05. I am successfully able to build for iMx6 and it's creating uImage for "printf" script. But when i am running this uImage on the Board and its giving following messages : starting Kernel... Genode 14.05 Kernel Initialized int main( ) : --- create local services--- failed to communicate with thread event Any idea How will I start kernel ? where should i look ??

Genode & IPsec
by Mhamad Hmad 10 Jul '14

10 Jul '14

Hi All, I would like to bring IPsec to Genode , if there any one interested to participate and share his experiences . I will start step by step and with the easy parts of the IPsec , depend on static configurations and maybe later we will implement the remain features. thanks, Mohammad

RPC with LWIP
by Mhamad Hmad 07 Jul '14

07 Jul '14

Hi, i will try explain what i want and what i did and then what i am facing, What i am trying to do : - using only one LWIP (tcp-ip) stack - the communication with lwip will be by using RPC calls. - the system should be multi-threading and serve many process in the same time What I did, - I created the client - server for the RPC which invoke the lwip methods. I will use the server only . - I created the libc_rpc_lwip plugin which is similar to libc_lwip . in libc_rpc_lwip i have an aobject of the Connection to call the methods. - Since i want only one stack in the i did not initialize the lwip from the constrcutre of the plugin that is mean : Plugin::Plugin() { PDBG("using the RPC lwIP libc plugin\n"); //rpcclient.r_lwip_tcpip_init(); this is commented } and i made the initiation in the RPC server and i used static IP for now ( I don't want to handle the libc_lwip_nic_dhcp right now) and this is the main method in the RPC server int main(void) { Cap_connection cap; static Sliced_heap sliced_heap(env()->ram_session(), env()->rm_session()); PDBG("lwip init has been started."); lwip_tcpip_init(); enum { BUF_SIZE = Nic::Packet_allocator::DEFAULT_PACKET_SIZE * 128 }; lwip_nic_init(inet_addr("10.0.2.18"), inet_addr("255.255.255.0"), inet_addr("10.0.2.1"), BUF_SIZE, BUF_SIZE); PDBG("gotting ip is done."); enum { STACK_SIZE = 7096 }; static Rpc_entrypoint ep(&cap, STACK_SIZE, "rpclwip_ep"); static rpclwipsession::Root_component rpclwip_root(&ep, &sliced_heap); env()->parent()->announce(ep.manage(&rpclwip_root)); /* We are done with this and only act upon client requests now. */ sleep_forever(); return 0; } - for testing i am using simple echo server and make it configure it to use the libc_rpc_lwip insread of libc_lwip and i was succeeded . What I am Facing: - when i tried to run more then one echo server ( in different port) ,the lwip is not working will and what i found that when the tow echo server try to accept connection the first one will block the other. and it means that lwip is not multi threading any more. Is the RPC prevent the lwip multi-threading or I am doing some thing wrong . I maنe my problem easy to be understood, if not just ask me to clarify. Thank you in advance -- *Mohammad *
