Microcode Patch Support

AMD provides microcode patch support for processors belonging to AMD processor families 10h, 11h, 12h, 14h, and 15h. This site targets Linux®, and Solaris based OS distributions.

End-users

If you are an end-user, AMD does not provide end-user support. Please refer to your operating system (OS) documentation for further details. The tools and patches mentioned on this page are usually delivered through your operating system package management or configuration utilities.

OS vendors

General Information

There is one single file (container file) containing all microcode patches for AMD families 10h - 14h processors. For AMD family 15h processors there is a separate container file. Microcode patches are not incremental, therefore you only need to make sure you have the latest container file for your AMD processor family.

The container file(s) are part of a container file package which also provides release notes for all included microcode patches, a short README file, and install instructions.

See Download section below for download instructions.

For further information or feedback please post your questions to linux-kernel@vger.kernel.org where AMD people will eventually pick it up..

Linux

Support for updating microcode for the AMD processors listed above will be available starting with kernel version 2.6.29.

Microcode update for AMD processors uses the firmware loading infrastructure.

Solaris

Support for updating microcode for the AMD processors listed above is scheduled to be available in the first 2009 release of OpenSolaris and in Solaris 10u8.

A tool called 'ucodeadm' is used to load microcode on a running system or install it to a known location where the kernel will look for it at boot time.
