This is why I have for the longest time been saying that Linux/x86 is a bad thing to have take over the world. There should and need to be more options than just Linux and just x86_64.

The world still needs mainframes and it still needs AIX and Solaris. The world still needs Z, POWER, SPARC.

The world needs an open source CPU.

Log message:
Update the Intel microcode once the root filesystem has been mounted.
This depends on the intel-firmware package that contains newer Intel
microcode which will be installed automatically by fw_update(1).

The update should happen much earlier since updating the microcode can
add or remove not only feature flags but also whole features. For now
only update feature flags that are relevant to Spectre.

Patrick and others commited amd64 Intel cpu microcode update code
over the last few days. The approach isn't perfect, but it is good
enough for a start. I want to explain the situation.

When you fw_update, you'll get the firmware files.

Upon a reboot, it will attempt to update the microcode on your cpus.
Maybe there isn't a new microcode.
</Edit>

It is worth to note that a lot of sources claims that updated microcode contains flaws.

Withdrawn Broadwell & Haswell CPU Microcode Update: Intel provides the CPU microcode updates required to address Variant 2, which manufacturers like Lenovo then incorporate into their UEFI firmware. Intel has notified manufacturers of quality issues in the initial Broadwell and Haswell microcode updates with instructions to no longer distribute the affected microcode. As such, Lenovo has withdrawn previously issued UEFI firmware containing the affected Broadwell and Haswell CPU microcode.

I'm running -current with the Intel firmware and having no issues, but on a Sandy Bridge (I5-2520M).

I think that Intel does not prepared microcode update for Sandy Bridge yet. Older generations, such as Sandy Bridge, are going to receive microcode updates to mitiagate Spectre later. Probably February or even March.

The January 8 microcode update was applicable, according to Intel, but it may just be an all-inclusive package.

I extracted that archive and in release notes I don't see any Sandy Bridge update, but maybe these shortcuts and numbers are hiding Sandy Bridge from me.

There is microcode for it, but it doesn't appear to have been updated since November 17.
  • The web page lists the CPU in its "This download is valid for the product(s) listed below" section.
  • The kernel searches for /etc/firmware/intel/06-2a-07 which is included in the bundle.
