Same for me. And :
# dpkg -l amd64-microcode
ii amd64-microcode 3.20240820.1~deb12u1 amd64 Platform firmware and
microcode for AMD CPUs and SoCs
I've the same package:
ii amd64-microcode 3.20240820.1~deb12u1 amd64 Platform firmware
and microcode for AMD CPUs and SoCs
But I got :
# cat /proc/cpuinfo | grep microcode
microcode : 0xa601206
[x cpu nb]
If you have the same CPU this is really unusual, likely you have a newer
CPU, I've a:
~$ grep "model name" /proc/cpuinfo | head -1
model name : AMD FX(tm)-8350 Eight-Core Processor
Previously you said :
The issue is that I'm running an homemade Kernel image that it had the
CONFIG_MICROCODE_AMD item disabled by me mistakenly, so I'm not sure that the
microcode of my CPU was updated. Of course I've rebuild and installed a new
kernel with that item enabled before rebooting.
I also build my custom kernel. I use sources from 6.10.6-1~bpo12+1. I
have no CONFIG_MICROCODE_AMD but a CONFIG_MICROCODE set by
CONFIG_CPU_SUP_AMD. Which kernel version do you use ?
The one provided by Debian 12.7:
$ LANG=C dpkg -l linux-source-6.1
Desired=Unknown/Install/Remove/Purge/Hold

+++-================-============-============-=======================================================
ii linux-source-6.1 6.1.106-3 all Linux kernel source for
version 6.1 with Debian patches
Me too I've CONFIG_CPU_SUP_AMD but looking at the help page it doesn't
select anything.
