Hello! I'm running netperf TCP_STREAM and TCP_MAERTS tests for lxip stack and i obtained extremely low result - 5x10^6 bits/s while the maximum throughput is 1000 mbit/s . I wonder what could be the reason for that. Anna

23 Mar '15

Hello everyone, the date for this year's Genode Hack'n Hike held during 11-16 of September is approaching. Genode's developers will spend those days in the beautiful scenery of the Bohemian Switzerland, relaxing, hiking, and hacking on fun side projects. The Hack'n Hike will be the perfect setting for getting involved with the community, catching up, or just hanging out with the Genode crowd. There is still room for more participants. Genode Labs sponsors the event. So your participation/accommodation is free. If you like to join in, please get in touch by writing to hacknhike@...1... or commenting on https://github.com/genodelabs/genode/issues/793.

Malloc / free ansd rump_fs ->Slab-backend exhausted
by unknown＠example.com 05 Sep '14

05 Sep '14

Hi, i try to open a file. I used the following code: //malloc char * buffer = (char*) Genode::env()->heap()->alloc(sizeof(char)*lSize); FILE* pFile = fopen(fileName, "rb"); size_t result = fread (buffer,1,lSize,pFile); fclose (pFile); //free (buffer); env()->heap()->free(buffer, 0); The code seems to work if the file is quite small. I try thre same with a file of size 128 MB. I have given rump_fs a quite large quota of 520M [Quota exceeded! amount=69632, size=8192, consumed=65536[0m [Could not allocate metadata[0m [init -> rump_fs] [upgrading quota donation for Env::RAM (8192 bytes)[0m [Quota exceeded! amount=77824, size=8192, consumed=73728[0m [Could not allocate metadata[0m [init -> rump_fs] [upgrading quota donation for Env::RAM (8192 bytes)[0m [init -> rump_fs] [Slab-backend exhausted! And from this point onwards only Slab-backend exhausted messages are shown. Is there some max size for ram quotas? Best regards, Wolfgang

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 30 Jul '14

30 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
