請問編 kernel 的 cpu type 和 -march

文章garyzyg » 週一 2月 06, 2006 6:36 pm

小弟有兩台機器, 一台 P4 PC, 一台 Pentium M Celeron laptop
gcc 是 4.0.1, kernel 是 2.6.12

1. 若要為 Pentium M Celeron 編 kernel, 那 .config 裡的 cpu type 該選哪項呢?
而 CFLAGS 的 -march 又該選哪種呢?
(編出來的 kernel 只會在這台機器上用)

2. 若把 P4 的 .config, -march 都設成 pentium4, 會 tune 到最好嗎?

以上, 在只考慮 .config, -march 的情況下, 要如何調整呢?

小弟用的是 Mandriva, 不過都大同小異, 希望各位大大能不吝賜教!
