Custom kernel using kernel-source

**BenderBendingRodriguez** · 09-Jun-2009, 03:05

Could anybody tell me how can i build a kernel rpm package using a bit modified config file? The only things i want to change is the preemption, cpu and Hz settings. I want it to stay as a 3 parts kernel package (base, extra etc. )

Anyone knows how i can accomplish this?

P.S. Using the kernel-source packages i understand i'll keep all the apparmor patches right?
P.S.2 I managed to create custom kernels etc. but checkinstall doesn't seem to work with that one.

I understand that i need to copy kernel source directory to other directory and customize it there, after that i'd want to create a kernel-source and kernel-default packages.

You posted this is in Applications. I cannot help you out on this one, but don't you think you'be better of putting this in Programming and Scripting?

What does it have to do with programming or scripting

?? There is no "kernel" section in these forums so i had to choose one

Customizing a kernel to me has to do with programming and scripting. Editing sources or compiler scripts

I doubted when I wrote it, it's just that customizing kernels is not a daily routine amongst users. It was meant as the gentlest suggestion to maybe get more attention for your matters.

If you say so

Well i got around that problem, but i couldn't change it's identification name from default since it was bombing out

The answer was stupid simple

make cloneconfig (after that customize it with make menuconfig or make xconfig (GUI) )

make rpm (create kernel-xxx and kernel-source-xxx)

P.S.Right now i'm tuning it to have all needed modules built-in and the rest as modules

Hi
If you grab the kernel src rpm then unpack it and add a patch, then
move all the unpacked files and your patch to
the /usr/src/packages/SOURCES directory then build it from there with
rpmbuild -ba <name_of_spec_file>

What are the config changes and what kernel?

What i did is that i used the default kernel-source package from oss repo (not the src.rpm), copied to a folder /home/<user>/build , customized it there (set preemptive, Hz to 1000, CPU arch to Core 2 and unticked some hardware i don't have and which is safe to not build (ISDN, RF, and some other). The only drawback was that i couldn't change the local version string and had to leave it as default (i installed the trace kernel to be able to install my custom one

)

I used the 2.7.27.23 (latest one for 11.1)

P.S. By the way, the ext4 patches introduced in this kernel make the ext4 reliable as in 2.6.29 (are the patches backported or something?) ?

Hi
Have a read here;
How To Compile A
Kernel - The SuSE Way

Not sure about the ext4 patches, I'm using ext4 on 11.2 m2 though.
