Re: [opensuse] loading custom kernel modules

Hi Matthew,

After building and installing the module, did you run 'depmod -a' ?

Once you can modprobe the module, you can edit /etc/sysconfig/kernel:
edit the line INITRD_MODULES="......."

You will then need to build a new initrd by running 'mkinitrd'. This
will forceload the module at boot time.

Regards

Sean

I've a server with a Areca RAID card running 10.2

Now there isn't a default driver for this so I have to compile either a custom
kernel or module.

For ease I'd rather compile the stand alone module and just load it in as
it'll make updating the kernel easier.

So I go into the driver source directory and run the following command:

make -C /lib/modules/`uname -r`/build CONFIG_SCSI_ARCMSR=m SUBDIRS=$PWD
modules modules_install

Which builds the correct module and installs it to:

/lib/modules/<CURRENTKERNEL>/extra/arcmsr.ko

Now I can use insmod /lib/modules/2.6.18.8-0.3-default/extra/arcmsr.ko to load
it and it works fine.

However unlike the rest of the modules in the kernel it's not pathed so I
can't add it to /etc/modprobe.conf.local as it doesn't like absolute paths in
there.

This means I can't auto mount the logical drive on this card via /etc/fstab.

I can get around it by using a startup script that loads the module and then
mounts it but as it's not 'the proper way' of doing things it's bugging me.

If I create a whole new custom kernel then it's fine but I don't want to have
to build all that every time a new one comes out when I could just compile a
single module in a second.

Any help would be appreciated.

Regard

Matthew
