CPU Microcode - Debian Wiki

[Georgi Naplatanov <gosho@oles.biz>]

Hi all!

I've just read Debian's Wiki page about CPU Microcode and there are 
mentioned Intel's and AMD's processors for AMD64 architecture.

What is the situation with processors from other architectures 
(arm64/AArch64 for example)?

 - do they have microcode?
 - can microcode be updated for these processors (from different 
architectures) by Linux kernel? Is this supported by Debian GNU/Linux?

Thanks in advance.

Kind regards
Georgi
