配置内核的命令是：

# make config 文本配置方式

# make menuconfig 菜单配置方式

# make xconfig 图形界面配置方式

我们可以采用任何一个命令配置内核，一般推荐使用make menuconfig来配置内核。

一．代码成熟度选项

Code maturity level options - [*] Prompt for development and/or incomplete code/drivers [*] Select only drivers expected to compile cleanly

在内核中包含了一些不成熟的代码和功能，如果我们想使用这些功能，想打开相关的配置选项，就必需打开这一选项。

二．通用设置选项
