Select this to apply patches to the CPU microcode provided by
AMD without source, and distributed with coreboot, to address
issues in the CPU post production.
Microcode updates distributed with coreboot are not necessarily
the latest version available from AMD. Updates are only applied
if they are newer than the microcode already in your CPU.
Unselect this to let Fam10h CPUs run with microcode as shipped
from factory. No binary microcode patches will be included in the
coreboot image in that case, which can help with creating an image
for which complete source code is available, which in turn might
simplify license compliance.
Microcode updates intend to solve issues that have been discovered
after CPU production. The common case is that systems work as
intended with updated microcode, but we have also seen cases where
issues were solved by not applying the microcode updates.
Note that some operating system include these same microcode
patches, so you may need to also disable microcode updates in
your operating system in order for this option to matter.
