Back to UTCB IPC
by Marc CHALAND 11 Oct '09

11 Oct '09

Hi, I am back with my problem with UTCB IPC. To sum up the context : I use pure l4env applications. Here is the scenario between my server and my client : 1. client makes an UTCB IPC to manager. Manager does an l4rm_area_reserve, creates a rcv_fpage, creates worker and sends back worker thread id to client. 2. client allocates memory and associated flexpage and sends it to server. 3. UTCB IPC is sent to worker with 3 parameters : - on client side : utcb->values=0xbff00200: arg1=0x2 arg2=… [View More]

DDEkit for Linux2.6 from svn
by Shakthi Kannan 03 Jan '09

03 Jan '09

Hi, I would like to know from where I can get the DDEKit (Device Driver Environment) for Linux2.6 from svn? http://wiki.tudos.org/DDE/DDEKit >From the svn documentation: http://www.inf.tu-dresden.de/index.php?node_id=1735&ln=en ./repomgr modules lists the following: dice, fiasco, hello, l4env, l4linux-2.6-env. Thanks! SK -- Shakthi Kannan http://www.shakthimaan.com

Hi at all, I am working on a project that makes it necessary to observe file system events.Therefore I plan to use the inotify subsystem from the kernel. Does L4 support inotify ?? Thanks in advance! Regards, Gianfranco

I boot it from a CD-ROM with L4 files, linux kernel and initrd on it. Here, removing "all_sects_writable" makes no difference. What interesting, with these settings the system is loading, the only warning a system gives is a warning that can't sync hardware clock with system timer, iopl(3) call failed; and also I cannot start X11. But access to eg. disks works. >> Also, each time I access /dev/null, the message is displayed that >> access is denied. > >How do you try to access it? /dev/null should look like this: >0 crw-rw-rw- 1 root root 1, 3 Jan 1 00:00 /dev/null yes, it appeared that the permissions for /dev/null were crw-r--r--, so users, other than root, have not write permission My fault... but I thought it something related with X11 not starting. >> Third, I got PCMCIA GPRS modem to power up and register in a GSM >> network (power Led is on and Network available Led is flashing).

You can >specify '-noserial' on the Fiasco command line to disable the usage of >ttyS0. Yes, the modem has two comm ports that could be accessed equally. In normal Linux they are ttyS0 and ttyS1. I removed "-serial" option from bootstrap command line and changed "-serial" to "-noserial" in the command line of fiasco. But still no result. I created /dev/ttyS0 by "mknod /dev/ttyS0 c 4 64" and likewise for ttyS1. When I tried to launch minicom, it says that no such device or address. After I did "modprobe serial_cs", minicom started but it still does not react to AT commands, so it seems that serial driver don't work. Maybe, serial_cs is wrong driver or this is the result of having not all I/O privileges? >> Fourth, I thied a wifi MiniPCI card Intel PRO/Wireless 2200 to get >> working in l4linux.

I had CONFIG_FW_LOADER enabled but there was "CONFIG_FW_LOADER=m", not "CONFIG_FW_LOADER=y". I changed this option to the latter and recompiled the kernel, but firmware still not loading.

Then a set of messages with call trace appeared and a message that "depmod killed". What is interesting, depmod worked when the number of modules was relatively small.

Dear all, I am working on a project which porting fiasco to a ARM&DSP platform. Now I have questions about the fiasco boot sequence in arm side. First, when doing a workable kernel image, we should use the l4 package *[1]"bootstrap" (l4/pkg/bootstrap)* to encapsulate the needed modules, for example: roottask, sigma0, and the real fiasco kernel(it means the building image in kernel/fiasco/builddir/fiasco.image).

On ordinary Linux Kernel it works well. I tried to use a fbdev driver in X.Org. Also, each time I access /… [View More]dev/null, the message is displayed that access is denied. Third, I got PCMCIA GPRS modem to power up and register in a GSM network (power Led is on and Network available Led is flashing). This modem appears to an OS like ordinary PCMCIA comm port, but minicom does not react to AT commands, though, PCMCIA stack detected the card, but did not enabled ttyS0 and ttyS1 ports on the card. It seems I loaded all PCMCIA stack modules and hotplug support. Except for serial_cs module which warns that "no high memory space available!". When I did configuring the linux Kernel, the build system did not give me a possibility to specify high memory up to 4 Gb. What should I do with it? Fourth, I thied a wifi MiniPCI card Intel PRO/Wireless 2200 to get working in l4linux. I tried to load all wifi modules like in ordinary Linux kernel on the same machine, but when I trying to make the network interface up, it says that device does not exists. When I check dmesg output, there is a message that a firmware could not be loaded. I unchecked the checkbox "Prevent the firmware from being built" and "Do not enable drivers which require firmware loading" and it seems that firmware must be built. The firmware is in /lib/firmware and is called ipw2200-bss.fw. What should I do to get firmware loaded? The question is, does hotplug work in l4linux and does work PCMCIA and wifi support and should I try it and what options I could miss? Also I noticed that CD writing by cdrdao and cdrecord does not work, the console is either hangs until reboot, or the number of call trace messages are displayed. And the last, I tried to build l4linux under l4linux itself. The build is generally working, except for when doing "make modules_install" depmod crashes. Should I report these errors or they are known problems?
