New kernel & modules

JJX · 09-15-2004, 02:14 PM

In my current configuration i am using several modules (hostap , i2c, lm_sensors etc...)

If i upgrade my kernel (from 2.4.25 to 2.4.27) i have to recompile all modules again or i can keep the old ones?

Exist any tool that can help me with the job?

You'll have to recompile them.

The easiest way of doing that would be to copy
linux-2.4.25/.config to linux-2.4.27/.config
and run "make oldconfig"

Cheers,
Tink

One of the nice things about Debian is that it makes kernel compiling very easy. First you run make menuconfig (or make xconfig) to get an easy-to-use graphical configuration screen. When you're finished configuring everything, just run 'make-kpkg kernel_image' and it will automagically compile the kernel and all modules and create a nice .deb package for you to install. Then dpkg -i <kernel-image-package-name> and reboot. It will even update lilo or grub for you.

The modules i am using arent in the kernel

Are modules that i created manually from sources....

If i follow 'David the H.' suggestion kenrel and modules will be in one deb package? If yes, i cant use the modules with next update.

You create the install the modules when you do make modules and make modules_install...

Are you talking about installing a kernel binary or doing a new kernel compile???

Using kernel 2.4.25 with some modules compiled from sources (ex. hostap = doesnt exist in the kenrel source tree)

tar zxvf <kenerl.2.4.27>
make oldconfig (using my oldconfig)
make bzImage
make modules
make modules_install
copy bzImage
update lilo
reboot

Now can i use hostap module from old kernel ? No, I have to recompile each module again.
`David the H.` suggestion apply here?

I don't know what hostap is. Can you get it as a source patch for the kernel perhaps?

JJX · 09-18-2004, 08:45 AM

Yes is possible to patch the kenrel....

What I mean is that when you use kpkg, the kernel will get compiled and installed where it needs to go, and the modules will get compiled and installed where they're supposed to go, just as if you used a stock kernel. All it does is make compiling and installing easier; it doesn't do anything different otherwise.

Whenever you update the kernel, you're always supposed to update the modules as well anyway. It's not a good idea to use old modules with a new kernel, or vice-versa.
