CONFIG_MICROCODE? "/dev/cpu/microcode - microcode support"?
按照kernel-seeds的说法,这个选项是用来更新处理器的微指令的。
http://kernel-seeds.org/settings/2.6.31/settings-03.html
- Enabling this setting will allow you to update the microcode of most Intel and AMD processors. This also requires you to emerge -av microcode-ctl to be effective. Since being up to date is a good idea, this setting defaults to on. If microcode-ctl isn't emerged, this setting does no harm.

更详细的解释可以参见: http://urbanmyth.org/microcode/
sys-apps/microcode-data似乎包含的最新的Intel处理器microcode。
鉴于我没看出这个有什么好处(Intel 连microcode的Changelog都没提供...),我个人是一向不起用它的。 |
