Anyone have some ideas why they never built an arch for p4 CPUs into the kernel? I realize that these are covered by i386. A little while ago, after looking round a bit in a custom tree and creating a p4 arch myself (Im not a programmer BTW, just hacking, pruned out some 'surplus' code mostly, using 2.6.14), a clean build ran in *lots* less time.
my 2.6.11 source tree has the option to target p4's: make menuconfig "Processor type and features" -> "Processor family" -> ┌───────────────────────── Processor family ─────────────────────────┐ │ Use the arrow keys to navigate this window or press the hotkey of │ │ the item you wish to select followed by the <SPACE BAR>.
