SubjectKernel 2.6: new features and older computers
Greetings,

I am looking for some information on the issues listed below for two
reasons. One is an article I am writing for a magazine, the other (as
the coordinator of the non-profit RULE project, see my signature) is
to understand if, how and how much the next linux kernel can be kept
compatible with older computers.

Any feedback is welcome. Should you have the time and right mood to
answer here or privately with detailed explanations, thanks a thousand
in advance. If not, please just point me to the relevant stuff to read
(be it URLs, email threads, comments in specific source files,
whatever). I have already downloaded the "wonderful world of Linux
2.6" and the documents pointed in it.

On to the questions now:

1) minimal hw requirements (RAM, disk...) both to *use* and to
*compile* the kernel

2) Which compilation switches could be used, if any, to lessen the
above requirements and increase performance on obsolete systems
(which in RULE means starting from 386/486/586 CPUs, 16+ MB RAM,
hard disk ~ 400/500 MB, and the kind of peripherals used 6/7 years ago)

3) Details on how the build system is changed
4) What is RCU and which kind of performances it will improve
5) Online Kernel-related tutorials which I could/should mention in the
"resource" section of the article
6) Anything else you might find relevant

Thanks again,

Marco Fioretti
