HACK

useful for getting set up for the fancy login consoles [Hack #20], which uses the

Qingy frame-buffer login manager. If you intend to implement any hacks

that require frame-buffer support, using the CKO kernel is an easy way to

prepare.

This pack of hacks shows you the advantages of using the CKO kernel, and

one way to tweak CKO performance in real time as you need it.

Before getting started, you should be forewarned. Only one hard and fast

rule applies when it comes to tweaking the performance of any kernel,

whether it’s a standard or a custom kernel: the rules will eventually change.

The Linux standard plain-vanilla kernel has been changing rapidly in terms

of the way it handles memory and swapping, for example, so what you

might have learned months ago about tweaking memory swap performance

in the standard kernel might be useless knowledge today. The same is also

true for custom kernels, such as the CKO kernel. The best way to find out if

or when the following advice becomes obsolete is to visit the Con Kolivas

kernel patch home page at http://members.optusnet.com.au/ckolivas/kernel/.

You can usually find the latest CKO patch set at http://kem.p.lodz.pl/~peter/

cko/. The page also includes a link for patch sets for older kernels, too.
