Modules and the kernel
So, I finally have a cross-compiler set up, and have been able to compile some modules for the A-100. But while investigating the filesystem, I notice that it doesn't use regular kernel-modules, but some kind of directory tree... I've so far been unable to find any information about how this works, and to be honest, I'm a bit unsure what searchwords to use. "Kernel module directory" doesn't exactly yield the right results.

So I call out to all of you who experiment with this lovely box: Do you know how this works? I'll contribute to the wiki-pages as soon as I have something that works, as I believe many more would love to have OpenVPN working (makes it so more handier when having off-site stream-server).

RE: Modules and the kernel
Not sure what you mean. The modules seem to be in the linux standard spot (/lib/modules/`uname -r`). The directory structure looks just like my ubuntu box. What exactly is the problem?

For a detailed description on how someone else got their own kernel modules to compile for the nmt, check out Fuse compiled by lundman

RE: Modules and the kernel
The modules (at least on my box) does not reside in the usual spot. There is no /lib/modules-directory. However, in /sys/ there is a directory called module, which has the following directory structure:

# cd /sys/module/
# ls
8250 ide_cd sg usb_storage
af_packet libata sr_mod usbcore
arusb_lnx llad tangox_ehci_hcd usbhid
ehci_hcd lockd tcp_bic
em8xxx scsi_mod uhci_hcd

in each dir there are either more dirs, or a file contaning settings:

# cd libata
# ls
# cd parameters/
# ls
# cat atapi_enabled

Doing an insmod results in this:

# insmod tun.ko
insmod: cannot insert 'tun.ko': Success

Funny that it says Success Wink

So, what I need help for is figuring out a way to insmod my own modules.
Looking at the Lundman-wiki (which I hadn't visited allready) there seems to be some tips I'll try to incorporate. Hopefully that will work Big Grin

RE: Modules and the kernel
run "dmesg" to get the error from kernel, even better, run "cat /proc/kmsg &" before. Most likely is missing link-time functions.

RE: Modules and the kernel
Thanks Lundman. Seems that the version magic was just missing the right gcc-bit Wink

tun: version magic '2.6.15-sigma preempt MIPS32_R2 32BIT gcc-3.4' should be '2.6.15-sigma preempt MIPS32_R2 32BIT gcc-4.0'

I'll recompile my toolchain and retry Smile

RE: Modules and the kernel
Someone Could explain how to add the IPv6 module in the PCH A110 kernel
I tried

# modprobe ipv6
modprobe: module ipv6 not found
modprobe: failed to load module ipv6

I think the reason is : module in not included in the kernel 2.6.15-sigma. Do you know how to add it ?

We have a NZBget compliant with IPv6 but the PCH-A110 no !Undecided

PCHA110/Spinpoint F1 1TB
