1.81. microcode_ctl

An enhanced microcode_ctl package 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 updated microcode_ctl package adds the following enhancement:

* The Intel CPU microcode file is updated to version 20101123. As of November 23, 2010, this is the most recent version of the microcode available from Intel. ( BZ#627798)

Note: To apply the changes, reboot the system after update.

Users of microcode_ctl are advised to upgrade to this updated package, which adds this enhancement.
