configure and compile own kernel

Keruskerfuerst · 11-15-2005, 06:32 AM

I am running Suse 10.0
kernelversion is 2.6.13-15
I want to include the filesystemdriver xfs in the kernel (not as module).
Compilation did run without problems; kernelmodules too.
But as I made mkinitrd, the script included xfs.ko in initrd.

Any solutions for that problem?

Yeah, you won't need to mkinitrd. Instead try doing this:

Specifically go near to the end of that thread. broch's, which is post #4.

I think you didn´t understand my question:

i want to include the filesystemdriver xfs in the kernel and don´t want to compile the filesystemdriver as module.

I checked the xfs option as included in the kernel (not module), but after compiling the kernel and the modules, the filesystemdriver was loaded as module.

I think that you don't understand: it is up to you how you manage xfs: module or kernel. You need to recompile it.
If I remember it correctly SuSE's config requires to compile FS (any) as a module. In your case grab vanilla kernel then you will be able to compile fs in kernel.

No!

I compiled the xfs filesystem directly into the kernel.
But mkinitrd added xfs.ko to initrd without need.
Cause: /etc/sysconfig/kernel must be changed; there is a list kernelmodules added to initrd.

1) check out your .config (after you compiled kernel, not before)
2) have you at least changed kernel name? If you havend, then module is still there from previous kernel.

mkinitrd reads only what's in your kernel, can't make modules. If you really compiled fs into kernel, then mkinitrd will not be able to make modules. initrd is only a helper image that allows to load modules before kernel starts to look for necessary crap (ie disk controllers, fs and so on), so obviously it can't make modules if there is none.

I have compiled the kernel: xfs is included in the kernel (not as module)
compiled the modules; installed the modules
edited /etc/sysconfig/kernel: deleted xfs.ko from the kernels module list.
mkinitrd.

xfs.ko is not loaded.

this is pretty bizarre way of getting required result, but important thing is that it worked for you.

Yes, the straight forward way should be:
configure kernel
compile kernel and modules, make mkinitrd
kernel should only load modules, which are necessary.
I included xfs in the kernel, but xfs.ko was loaded too. I proved that with lsmod.
