Gentoo Linux安裝--Intel CPU類型設置及優化

主機平台：Gentoo 11.2

內核版本：Linux Kernel 3.2.1

CPU型號：Pentium Dual-Core T2370 32-bit

1、通過查看CPU的信息可以看到Intel Core 2 Duo/Quad / Xeon 51xx/53xx, Pentium Dual-Core T23xx+/Exxxx的硬件信息如下：

首先設置/etc/make.conf中CFLAGS

我的make.conf文件如下：

1. CFLAGS="-O2 -march=prescott -pipe -fomit-frame-pointer"
2. CXXFLAGS="${CFLAGS}"
3. # WARNING: Changing your CHOST is not something that should be done lightly.
4. # Please consult http://www.gentoo.org/doc/en/change-chost.xml before changing.
5. CHOST="i686-pc-linux-gnu"
6. MAKEOPTS="-j3"
7. USE="gnome X dbus hal v4l -qt3 -qt4 gtk laptop samba -kde -arts consolekit policykit udev alsa cdr -cups -bluetooth"
9. GENTOO_MIRRORS="http://mirrors.163.com/gentoo"
11. SYNC="rsync://mirrors.163.com/gentoo-portage/"
13. LINGUAS="en_US en_GB uk zh_CN "

如果機器是64位的，則設置CFLAGS如下：

CHOST="x86_64-pc-linux-gnu"

CFLAGS="-march=nocona -O2 -pipe -fomit-frame-pointer"

2、內核編譯選項
