[solved] microcode confusion

I have an Intel i7-6700.
Help me figure this microcode thing out please.

Wiki says here that there are some processor updates that need to be installed. Okay.
https://wiki.archlinux.org/title/microcode

The intel-ucode package is already installed and GRUB has the same entry as on the wiki

echo 'Loading initial ramdisk ...'
initrd /intel-ucode.img /initramfs-linux.img

What I don't understand is whether or not it's even working.

Wiki says after this

journalctl -k --grep=microcode

I should see this

microcode: microcode updated early to revision 0xde, date = 2020-05-18
microcode: sig=0x806ec, pf=0x80, revision=0xde
microcode: Microcode Update Driver: v2.2.

Instead I got this

Jan 18 21:49:05 dragon kernel: SRBDS: Mitigation: Microcode
Jan 18 21:49:05 dragon kernel: GDS: Vulnerable: No microcode
Jan 18 21:49:05 dragon kernel: microcode: Current revision: 0x000000f0
Jan 18 21:49:05 dragon kernel: microcode: Updated early from: 0x000000c6

I have a suspicion that something is wrong but I'm not sure so please tell me.

Re: [solved] microcode confusion

Jan 18 21:49:05 dragon kernel: GDS: Vulnerable: No microcode

That's in fact proving microcode has been loaded:

no microcode
   

Processor is vulnerable and microcode is missing mitigation. AVX disabled as mitigation.

So does this mean that intel just didn't make this microcode for my processor?

Re: [solved] microcode confusion

6700 should have microcode updates, unless you kept on top with your UEFI updates.

Ungrepped journalctl -k ?

Just checked, it's likely the microcode update message simply changed (... not sure when) but I also see the shorter form here, so things look correct.
