3.47. microcode_ctl

Updated microcode_ctl packages that add one enhancement are now available for Red Hat Enterprise Linux 5.

The microcode_ctl packages provide utility code and microcode data to assist the kernel in updating the CPU microcode at system boot time. This microcode supports all current x86-based, Intel 64-based, and AMD64-based CPU models. It 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 processors, as described in processor specification updates issued by Intel and AMD for those processors.

Users of microcode_ctl are advised to upgrade to these updated packages, which add this enhancement. Note that a system reboot is necessary for this update to take effect.
