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

Re: Genode Hack'n Hike 2013
by Norman Feske 23 Mar '15

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.

Progress of bringing Genode to seL4
by Norman Feske 12 Mar '15

12 Mar '15

Hello, I have written up the first of a series of articles about using seL4 as base platform for the Genode OS framework: http://genode.org/documentation/articles/sel4_part_1 I hope that it contains useful bits of information for novices of seL4 and Genode alike. Even though the article outlines a few hurdles, the overall experience of using the kernel had been overly positive so far. For those of you interested in tracking the progress of the ongoing work, here is the corresponding topic branch: https://github.com/nfeske/genode/commits/sel4 Cheers Norman -- Dr.-Ing.

Conference "New Directions in Operating Systems" in London
by Norman Feske 03 Nov '14

03 Nov '14

Hello everyone, I was made aware of the following event titled "New Directions in Operating Systems", which takes place on 25 November in London. http://operatingsystems.io The conference is organized by members of the Rump-kernel community. Since Genode is using Rump kernels, e.g., to provide file systems, there is an obvious connection between both projects. I am planning to attend and possibly give a talk. Maybe the conference is of interest to some of you, too? It would be a nice opportunity to catch up. ;-) Cheers Norman -- Dr.-Ing.

About privileged instructions on L4android
by li94575 03 Nov '14

03 Nov '14

Hi All, Can someone tells me how to execute ARM privileged instruction on L4android, such as " MCR, MRC......" I have a piece of code that needs to execute privileged instructions, but I don't want to put it all into the kernel ----Fiasco.OC. I want to know if L4android have any good ways to solve this problem.

AHCI Doesn't Work
by Nobody III 31 Oct '14

31 Oct '14

I have tested the run script run/ahci (os/run/ahci) on both foc-x86_64 and fiasco-x86. It doesn't work on either platform. In the "Limitations and Known Issues" section of the README, it does mention that it won't work properly on real hardware or on Fiasco.OC, but it also doesn't work on Fiasco in qemu. I would very much like AHCI to work on Fiasco.OC on real hardware. Can someone who understands the problems fix it? (Or teach me enough so I can fix it; note that all my experience with Genode is in configuration, not actual programming, and that I'm not familiar with OS development.)

Segmentation fault in ld.lib.so when using gzread
by Johannes Schlatow 31 Oct '14

31 Oct '14

Hey everyone, I'm using some 3rd party code that depends on zlib. In particular, it uses gzread() in order to read a file. Unfortunately, the corresponding piece of code causes a segfault in ld.lib.so. I narrowed this down to the following minimum example: gzFile gzfile_components = gzopen("test.txt", "rb"); unsigned char buffer[1024*1024]; gzread(gzfile_components, buffer, sizeof(buffer)); As you can see, the buffer is quite large but this the actual (and reasonable) value used in the 3rd party code. As soon as I reduce the size to e.g. 4096, the segfault is gone. The file I used has a size of 293 bytes. I'm using base-linux. I also remember using this code successfully on a different computer with an older version of Genode (14.03). Any ideas/comments on this?

L4Linux on x86_64
by Nobody III 31 Oct '14

31 Oct '14

It seems that L4Linux expects either x86_32 or arm. Would it work to compile the x86_32 version on x86_64? If not, why? What level of multiarch support does Genode have?

File Manager
by Nobody III 30 Oct '14

30 Oct '14

What level of file management does Genode have? Is there a graphical file manager available? Does noux support file management? Also, since I am considering implementing a file manager if one doesn't already exist, how would I do it? I'm thinking of porting PCManFM to Genode, so how does the filesystem work? (Does it have a single root directory like Linux, or does it just give you access to each filesystem like in Windows?)

Multiple Library and Binary Directories
by Nobody III 30 Oct '14

30 Oct '14

I have been looking through the Genode run scripts, and it seems that init will only look in the root of a ROM for both libraries and binaries. It would be very useful to be able to search for binaries and libraries in multiple directories (e.g. /lib, /usr/lib, /bin, /usr/bin, etc.) Also, is there a way to separate the library and binary directories without hacking init? If not, how hard would it be to hack init to add this feature?
