[SOLVED] Supermicro A1SAi with an Atom C2750 support

[rbronco21]

Is the Supermicro A1SAi with an Atom C2750 supported? I get a blank screen without a prompt in SSH when running corefreq-cli. I get a blinking cursor when I run corefreq-cli -c. When I ctrl-c, I get this:

I posted on the unRAID forum and was directed here.

Hello,
Thank you for this issue.

I'm looking for Avoton in my Wiki but don't find any previous executions with this architecture of CPUID 06_4D

Have a look in the kernel log for any issue with the driver corefreqk.ko

If any, please post whatever errors, trap of registers, functions backtrace.

However if no driver error, try starting the Daemon in debug mode: corefreqd -d

Also if CoreFreq happened to you within an UNRAID plugin, and you don't have a mean for command line tests, you can download the CoreFreq live image to troubleshoot the issue

[rbronco21]

This is going to be beyond me. If you are interested in the answer, I can work through it with you, but I'm fine if it's not worth the work. I believe I can boot the live cd through IPMI the next time my server is down, and I can run whatever commands you want and report back. Here is the relevant log and the results of corefreqd -d.

I will provide a fix in develop Hotfix_Avoton branch for your testings.

[cyring]

@rbronco21 : Hello

I'm providing a hotfix for Avoton architecture.

For your testings, you have the choice between:

• cloning the branch Hotfix_Avoton
• trying image archlinux-corefreq-hotfix-avn.iso

[cyring]

Can you plz give a try to the fix ?

[rbronco21]

I really wanted to get it compiled, but it was beyond me. I ran the live cd in an unRAID VM and it looks better than before. Is there anything specific you want me to try in this VM? Is the VM an acceptable test?

This is as far as I got with compiling. I wouldn't mind a hint if you have an idea. I got the packages installed to get this far, but I wouldn't be surprised if I missed something.

cd /tmp
git clone -b Hotfix_Avoton --single-branch https://github.com/cyring/CoreFreq.git
cd CoreFreq
make

.
.
.
make -j1 -C /lib/modules/5.10.28-Unraid/build M=/tmp/CoreFreq modules
make[1]: Entering directory '/usr/src/linux-5.10.28-Unraid'
make[1]: *** No rule to make target 'modules'. Stop.
make[1]: Leaving directory '/usr/src/linux-5.10.28-Unraid'
make: *** [Makefile:76: all] Error 2

[cyring]

Thanks for giving a test.
In fact, CoreFreq is aware about virtualization, it then won't probe the CPU very deep.
Only a bare-metal run will validate a good architecture support.

You already have the ISO: you now have to write it on an USB key and ask you BIOS to boot it.
There are many ways to flash the ISO; like dd within Linux; Rufus for Windows.
See
https://github.com/cyring/CoreFreq/wiki/Live-CD

As far I can see in your building log above, you are missing the Kernel development stack: headers on so on.
unRAID is a distribution for Production; this might explain those missing files.
That's why the ISO image is filling all the prerequisites.

[rbronco21]

Yeah, I just need time to shut down and reboot my server. Glad I got a good server mb so I can just mount the iso from my PC!

I'm also testing some architectures through the Scaleway infrastructure.
Unfortunately AVOTON is not part of their servers.

Once again, thanks a lot for your contribution to the project.
Can't wait to see your results.

@rbronco21 compiled the files for you and built a unRAID plugin package, but it will only work when you are on unRAID v6.9.2 (Kernel v5.10.28), I will send you a message on the unRAID Forums shortly.

@cyring please redirect such users directly to me when some things should be compiled on unRAID since this can be a little bit complicated if you don't have the right setup.

[cyring]

Lovely!

Are you happy with those results ?

[rbronco21]

I was looking for a better way to check frequency and temps so I only use the basic functionality, but it did that fine.

Issue appears solved
