I have Mandriva 2008.0 distribution. I compiled l4linux and got some problems with it. Maybe anyone knows what's wrong with the configuration? First, the problem is with X11 (X.Org), when I'm launching X11 by typing startx, there is an error
tal server error: xf86EnableIOPorts: failed to set IOPL for I/O (Invalid argument)
I compiled in the L4con/DOpE stubs but X11 don't work. On ordinary Linux Kernel it works well. I tried to use a fbdev driver in X.Org.
fbdev is a driver that will work. The problem is that X wants to have IO privileges which L4Linux does not have. This is actually feature rather than a bug. Why should X need IO privileges for just running the fbdev driver? Anyway, add 'allow_cli' in the loader config script to the L4Linux load line, and 'task modname "loader" allow_cli' to the roottask cmdline and it should give L4Linux/X the rights it likes to have.
I have these. My bootloader config is like this:
title L4Linux 2.6 [console] kernel $(L4)\bootstrap modaddr 0x02000000 module $(L4)\fiasco $(FIASCOARGS) module $(L4)\sigma0 module $(L4)\roottask -symbols -lines task modname "loader" allow_cli task modname "bmodfs" attached 7 modules module $(L4)\fiasco_symbols module $(L4)\fiasco_lines module $(PN)\names module $(PN)\log --prio 0xA1 --buffer 0 module $(PN)\dm_phys module $(PN)\simple_ts -t 380 module $(PN)\rtc module $(PN)\l4io module $(PN)\bmodfs module $(PN)\libloader.s.so module $(PN)\libld-l4.s.so module $(PN)\run module $(CFG)\run.cfg module $(LX)\vmlinuz26 module $(CFG)\l4linux26.cfg module $(LX)\initrd.img module $(PN)\l4con module $(PN)\loader --fprov=BMODFS run.cfg l4linux26.cfg vbeset $(VMODE)
and I have the following loader config file:
task "vmlinuz26" "mem=1800M no-scroll video=l4fb:refreshsleep:200 l4fb.nograb=1 load_ramdisk=1 ramdisk_size=4096 root=/dev/sda9 l4env_rd=(cd)/lx/initrd.img panicblink=0" allow_cli all_sects_writable priority 0xA0
My system is on /dev/sda9 (a partition on SATA harddisk). 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). 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?
Is the modem really using ttyS0? ttyS0 is used by Fiasco for the serial console and thus not available to L4Linux (or any other app). 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 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 FW_LOADER config option is not enabled. I guess this needs to be so.
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. So, it won't help. The error is like this:
Oct 17 15:10:49 localhost kernel: ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 1.2.2kmprq Oct 17 15:10:49 localhost kernel: ipw2200: Copyright(c) 2003-2006 Intel Corporation Oct 17 15:10:49 localhost kernel: __l4x_ioremap: Requested region at b8006000 [0x1000 Bytes] Oct 17 15:10:49 localhost kernel: __l4x_ioremap: Mapping physaddr b8006000 [0x1000 Bytes, b8006000+001000] to 3f58a000+000000 Oct 17 15:10:49 localhost kernel: ipw2200: Detected Intel PRO/Wireless 2200BG Network Connection Oct 17 15:10:49 localhost kernel: firmware: requesting ipw2200-bss.fw Oct 17 15:11:49 localhost kernel: ipw2200: ipw2200-bss.fw request_firmware failed: Reason -2 Oct 17 15:11:49 localhost kernel: ipw2200: Unable to load firmware: -2 Oct 17 15:11:49 localhost kernel: ipw2200: failed to register network device Oct 17 15:11:49 localhost kernel: ipw2200: probe of 0000:06:05.0 failed with error -5
-- This is from dmesg output. Maybe, I missed something other?
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?
Is it depmod or something different? depmod should work as Debian systems running it on every boot-up. Please report, I'll try to fix as I can.
Yes, I compiled the kernel and did "make modules_install". It copied modules to /lib/modules and started to make files describing the modules. 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. But when it was more than 700 modules, it crashed. What should I do to report the error? The messages are at linux console, not on commport, so is there a way to copy these messages? (The only way I see is to copy the parts of messages from screen using gpm mouse server).
