我想应用新的英特尔微码. 如何应用 intel-microcode 提供的微码更新?
我的微码已经非常过时了。
dmesg | grep microcode

通过
sudo apt-get install intel-microcode
之后,重新启动系统并使用以下命令检查输出
dmesg | grep microcode
这是我的过时的版本,我的cpu实在是太旧了
% dmesg|grep "updated"
[ 0.000000] CPU0 microcode updated early to revision 0x60f, date = 2010-09-29
[ 0.008000] CPU1 microcode updated early to revision 0x60f, date = 2010-09-29
