when you say "plug-in", do you mean to make it easy to plug-in per-cpu code at compile time, (eg config choice) or boot-time?
I'd love to see the latter, as i tend to use one kernel build across multiple machines (P54C, K6, K6-III). So ideally i'd like:
1. at compile time i have a choice something like include optimised memcpy routines for: O P5 O MMX only O MMX + 3DNow O Pentium III SSI O Athlon
and i'd just select all the machines that i need. Then at boot kernel could select appropriate memcpy method (is this possible though?).
regards,
paul jakma.
