我用的是赛扬420,官网说:
Intel Core Solo/Duo, Pentium Dual-Core T20xx/T21xx
vendor_id : GenuineIntel
cpu family : 6
model : 14, 22
model name : Genuine Intel(R) CPU TXXXX @ XXXGHz
model name : Intel(R) Celeron(R) CPU 220 @ 1.20GHz
model name : Intel(R) Celeron(R) CPU 4X0 @ XXXGHz
model name : Intel(R) Celeron(R) M CPU 4X0 @ XXXGHz
CHOST="i686-pc-linux-gnu"
CFLAGS="-march=prescott -O2 -pipe -fomit-frame-pointer"
CXXFLAGS="${CFLAGS}"
Notes:
* It has been confirmed by hongjiu.lu@intel.com that prescott is the correct microarchitecture to use with this CPU. http://article.gmane.org/gmane.comp.gcc.devel/83870
* The newer (eg. 420) Celeron-M processors are Core Solo based, not Pentium-M based. If your processor's family and model are 6 and 14, then you should use the -march=prescott option.
* Both the Celeron 4x0 and 220 run fine with Processor family (Pentium M) selected in the kernel.
我的是model 22,应该用哪个?
我现在比较保守,用的i686,有没有更合适的?对性能有影响么?
顺便问一句:再次编译内核时所用时间竟然是1分钟,我看别人一说编译内核一般也得十来分钟吧。我第一次编译的时间和别人差不多,后边再次编译时间就短了这么多?是不是那个什么pipe的作用? |
