Compile my own kernel?

Hi!

I wan't to edit and compile my own kernel, so I got even more structure on my machine - and I hope to get a little more performance.

How do I edit and Compile a custom kernel?

[EDIT] And maybe how I make all my own-compiled programs to be compiled to a Pentium4 processor As i could when I was a Gentoo user

Re: Compile my own kernel?

Kris;

There is a wiki for custom kernel generation.

Basically, you can use ABS to obtain the basic kernel  and its accompanying patches and config file.  ABS is  Arch Build System which somewhat automates the making of packages, including custom kernels.

Just run abs in CL and find the download in /var/abs/kernels.

The kernel you desire to customize is found therein.

You customize it by modifying the kernelconfig and setup PKGBUILD file.

Run "makepkg" on the PKGBUILD and then run pacman -A (name of custom kernel.pkg.tar.gz).  If using lilo run/sbin/lilo before reboot.

The steps are outlined in the wikis.

Best of luck!!!

Allright...

Is it "easy" or is it something I must be af 1337-haXor to do?

Re: Compile my own kernel?

You may experience "noobie pains" by running into typos, incorrect entries, and have to try again as I did (I am 81 soon).

If first you don't get pkgbuild to complete, you must remove the pkg and src folders from the directory before trying again...not included in wiki I recall!!

You must run this exercise in a directory other than the /var/abs/kernels directory as is outlined in the wiki.  Also, during th PKGBUILD."makepkg", a window opens with an opportunity to enter config again...x it out and continue....

Get your feet wet and observe other examples in the forum...  use search above the wiki icon.

Good luck!

Re: Compile my own kernel?

Kris - if you really want to do this, you need to do more than read the Arch wiki. Google for kernel howtos, and do some serious reading. No offence, but the fact that you're asking if it's easy suggests to me that you might not be quite ready for this.

Also, please bear in mind that the devs put a lot of work into the Arch kernel packages, based on many years of experience. It is almost certain that you will not get any practical performance gains from rolling your own. The same goes for recompiling your apps for P4.
