1.122. microcode_ctl

An updated microcode_ctl package that provides the latest version of the Intel microcode is now available.

microcode_ctl provides utility code and the microcode data itself -- supplied by Intel -- to assist the kernel in updating the CPU microcode at system boot time. This microcode supports all current Intel x86- and Intel 64-based CPU models and takes advantage of the mechanism built-in to Linux that allows microcode to be updated after system boot. When loaded, the updated microcode corrects the behavior of various Intel processors, as described in processor specification updates issued by Intel for those processors.

This update provides the following enhancement:

* this package contains the 2009-09-27 update to Intel's microcode. As of 2010-01-22, this is the most recent version of the microcode available from Intel. (BZ#526802)

All users running systems based on Intel processors are encouraged to install this update, which adds the most up-to-date microcode data from Intel to /etc/firmware as required. Note: a system reboot is necessary for the this update to take effect.
