microcode update

[fernandel]

I got a msg during boot: CPU microcode: no matching update found

My system: FreeBSD 15.1-RELEASE-p1
In /boot/loader.conf I have:

cpu_microcode_load="YES"
cpu_microcode_name="/boot/firmware/amd-ucode.bin"

I have installed cpu-microcode-amd and cpu-microcode-rc

lscpu shows:

In the past it worked but not anymore.

Thank you.

fernandel see if you have microcode package installed:
$ pkg info *microcode*

In your case you should have at least these two packages:
cpu-microcode-amd-20251202
cpu-microcode-rc-1.0_2

and I have in /boot/firmware/amd-ucode.bin

That is strange, I've checked my dmesg and i see lines like this:

Jul 14 09:17:28 cinder kernel: CPU microcode: updated from 0xa705206 to 0xa705208

AFAIK you don't need cpu-microcode-rc-1.0_2 for loading from loader.conf, it provides an rc script to load the microcode later.

I enable it rc.conf for loading later and disable in /boot/loader.conf and looks lie it works.
I tried to delete cpu-microcode-rc but it deleted also *-amd and when I pkg installed cpu-microcode-amd than install both again.

No, it doesn't work. I do not know what the problem is.

 sysctl -a | grep microcode
CPU microcode: no matching update found
        value:  cpu_microcode
