On my FX-8150, previous update was:
May 21 07:05:16 lab microcode_update[1093]: /usr/local/share/cpucontrol/microcode_amd_fam15h.bin: updating cpu /dev/cpuctl0 to revision 0x600063d... done.
With this update:
May 22 11:23:29 lab microcode_update[38938]: /usr/local/share/cpucontrol/microcode_amd_fam15h.bin: updating cpu /dev/cpuctl0 to revision 0x600063e... done.

∴sudo service microcode_update restart
Updating CPU Microcode...
Done.
I see nothing on the console.

I see nothing in /var/log/messages when attempting to apply the update to:
CPU: AMD A10-8700P Radeon R6, 10 Compute Cores 4C+6G (1796.66-MHz K8-class CPU) Origin="AuthenticAMD" Id=0x660f01 Family=0x15 Model=0x60 Stepping=1
Haven't dug into it yet.

On a AMD Threadripper 1900X I see "microcode updating..." and output of the CPU information. On a Carrizo APU, I see "microcode updating..." and "done", nothing else. How to check it DTRT?
Comment Actions
If it did anything, its logged to /var/log/messages. Search for "microcode_update"

You can also try x86info -a | grep Microcode before/after to confirm. In my case on an old FX-6100 I see Microcode patch level: 0x6000613 before and Microcode patch level: 0x600063d after (using the current devcpu-data package, not this patch).

On my AMD Ryzen Threadripper 1950X I see Microcode patch level: 0x8001127 before and after trying the microcode in this review (i.e., the new microcode_amd_fam17h.bin either does not contain microcode for Threadripper, or is not getting applied).
Comment Actions
I have yet to get a report of any "17h" machine ever updating. This concerns me a bit.
Comment Actions
Trying out some debugging here. Can someone apply this patch
https://people.freebsd.org/~sbruno/cpucontrol.diff.txt
And send me the results of something like the following? I put the amd microcode files in a seperate dir and *removed* the devcpu-data port as cpucontrol will *always* look at /usr/local/share/cpucontrol if it exists.
Comment Actions
I get the same output, i.e., "CPU is not found in the equivalence table" for all files.

Update to catch linux-firmware commit 7518922bd5b98b137af7aaf3c836f5a498e91609
- Processor Revision ID 0x00610f01 was accidently not included in the previous submitted microcode container file.
- Update the Version for family 15h microcode .bin file

Can you post the detection output for your CPU? I assume you have a 17h here, but I'm not sure. Something like this would be interesting to see.

Hrm. I guess this *is* working, at least for the EPYC I have at work.
With previous microcode files:
cpucontrol: found cpu family 0xf model 0x1 stepping 0x2 extfamily 0x8 extmodel 0. cpucontrol: microcode revision 0x8001227 cpucontrol: checking /usr/local/share/cpucontrol/microcode_amd_fam17h.bin.orig for update. cpucontrol: equiv_id: 8012 cpucontrol: patch_id 8001213, revision 8001227
With new microcode files:
cpucontrol: found cpu family 0xf model 0x1 stepping 0x2 extfamily 0x8 extmodel 0. cpucontrol: microcode revision 0x8001227 cpucontrol: checking /usr/local/share/cpucontrol/microcode_amd_fam17h.bin for update. cpucontrol: equiv_id: 8012 cpucontrol: patch_id 8001227, revision 8001227
I sure wish I could fine someone running a 17h that actually applies this update. :-(

cpucontrol print on multiple input files could be a lot more clear :(. I disambiguated it by copying fam17h to its own directory:
$ mkdir tmp $ cp -a work/stage/usr/local/share/cpucontrol/microcode_amd_fam17h.bin tmp $ sudo cpucontrol -vvv -n -d ./tmp -u /dev/cpuctl0 amd10h_probe: family: 0x17 cpucontrol: skipping ./tmp/.: is a directory cpucontrol: skipping ./tmp/..: is a directory amd10h_update: signature: 0x800f11 cpucontrol: found cpu family 0xf model 0x1 stepping 0x1 extfamily 0x8 extmodel 0. cpucontrol: microcode revision 0x8001129 amd10h_update: installed_cpu: 0x600f20 amd10h_update: installed_cpu: 0x610f01 amd10h_update: installed_cpu: 0x700f01 amd10h_update: installed_cpu: 0x800f12 amd10h_update: installed_cpu: 0x800f11 cpucontrol: equiv_id: 8011 $ echo $? 0
Nothing in /var/log/messages. Patch level is 0x8001129 per x86info.
This is on TR (fam 17h). Does that help? :-)

Hrm... Can you run it with my diff for more debugging goodness? https://people.freebsd.org/~sbruno/cpucontrol.diff.txt
Comment Actions
Sure.

Nothing in /var/log/messages.
Given "firmware processort_rev_id 8012, equiv_id 8011," I think this "fam17h" firmware is only for Epyc. IIRC that was true of the earlier Meltdown/Spectre microcodes too. They expect consumer CPUs to get this update via BIOS, I think?

My spider sense is tingling as well.

cpucontrol's probe finds family 0x17 ...
Can you instead try D155745
Seems reasonable to me. Thanks for digging in.

No, 15h. Using the latest diffs here and in D15574, I get:
