Ubuntu 15.04中的Intel微代码

Question

我想应用新的英特尔微码。如何应用英特尔-微码提供的微码更新？

我的微码太过时了。

dmesg | grep microcode
[    0.000000] CPU0 microcode updated early to revision 0x1b, date = 2014-05-29
[    0.088431] CPU1 microcode updated early to revision 0x1b, date = 2014-05-29
[    0.901761] microcode: CPU0 sig=0x306a9, pf=0x10, revision=0x1b
[    0.901768] microcode: CPU1 sig=0x306a9, pf=0x10, revision=0x1b
[    0.901776] microcode: CPU2 sig=0x306a9, pf=0x10, revision=0x1b

[    0.901833] microcode: Microcode Update Driver: v2.00 <tigran@aivazian.fsnet.co.uk>, Peter Oruba

我使用Ubuntu 15.04。

通过

sudo apt-get install intel-microcode

之后，重新启动系统并使用下面的命令检查输出

dmesg | grep microcode

这是我的过时版本，我的cpu太老了
