NUC8v5PNK firmware and acpidump

harwang

Hi,

 

I installed Ubuntu 20.04.2.0 LTS on NUC8v5PNK and installed acpica-tools to play with acpi tables. Basically I just follow the steps here: https://www.kernel.org/doc/html/latest/admin-guide/acpi/initrd_table_override.html

 

But I see errors like "could resolve symbol" in dsdt.dsl and if I do iasl -sa dsdt.dsl, I get compile errors.

 

I've tried all versions of acpica-tools for ubuntu listed here: https://www.ubuntuupdates.org/pm/acpica-tools. But none of them can create dsdt.aml.

 

Do you know where can I get the right version of acpica-tools for this beauty?

 

Thanks

Harry

Hello harwang, I just received an update on this matter.


After reviewing the case, we confirm, as you mentioned previously, that the software that you are using was downloaded from:

https://www.ubuntuupdates.org/pm/acpica-tools


This means that you are getting those apps from a 3rd party source, so what we recommend is to get in contact directly with the Linux distros for further assistance on this matter:

https://www.intel.com/content/www/us/en/support/topics/linux-osv.html


Or you can always visit Ubuntu forums as well for further support on this subject:

Hi Albert,

 

Thank you for the reply. I forgot to mention in my previous post that the reason I tried all versions of acpica-tools from the link is because the official ubuntu version I installed from apt install is also not working.

 

I think the best way to get the answer for this question is to ask the vender of the firmware writer, therefore asking Intel should be much better than asking Ubuntu.

Hi @harwang 

 

The NUC8v5PNK has been officially validated to work with Ubuntu 18.04 LTS*, refer to the following URL for further reference: https://www.intel.com/content/www/us/en/support/articles/000005628/intel-nuc.html so in a previous post you mentioned that the reason why you are using the acpica-tools from https://www.ubuntuupdates.org/pm/acpica-tools is that the official Operating System deployment is not working. We are very limited to support the acpica-tools, we dont know these tools, they are opened source and I would better recommend that you check with the developer of these tools but we can help you troubleshoot the issue with Ubuntu 18.04 LTS*.

 

Please provide us with a description of the issue, any pertinent log file or screenshot, and the Intel SSU log file https://www.intel.com/content/www/us/en/download/18895/26735/intel-system-support-utility-for-the-li...

Hi Ronny,

 

Thank you for your reply. Unfortunately I just pass the device to my colleague for other purpose, so I cannot install Ubuntu 18.04 LTS to try.

 

If you have a device, it will be very easy to reproduce the problem. The steps are here https://www.kernel.org/doc/html/latest/admin-guide/acpi/initrd_table_override.html.

 

To be more specific. You can do these on your NUC device booted by Ubuntu 18.04 LTS:

sudo apt install -y acpica-tools
mkdir tmp
cd tmp
acpidum > acpidump
acpixtract -a acpidump

 You will get a bunch of .dat files. Then:

iasl -d *.dat

 It will generate .dsl files for every .dat.   A .dsl file is just a txt file.

Please check dsdt.dsl to see if there are any errors inside. Then:

iasl -sa dsdt.dsl

If you see no compile errors and file dsdt.aml is created. That will be great. Just let me know the version of acpica-tool installed.

 

If dsdt.aml is not generated and you see compile errors, it means this version of acpica-tools cannot interpret the firmware correctly. There must be a right version of acpica-tools to do this.

 

Regards

Harry

Hi Harry,

 

Thanks for the details, yes I can test it but I need to first undertand what's wrong with the regular Ubuntu* 18.04 LTS deployment so that you need to use the acpica-tool.  I understand that this tool may be giving you errors but let me tell you that we usually dont provide support to 3rd party applications as our scope is limited to the Operating System installation especially when dealing with open-source software.

Even if I test it and get the errors you report, I need a strong justification to bring this over to the engineering team, this justification can vary from technical issues such as the Operating System not working as expected or business-related, for example, a BIOS feature request for a large number of units for a specific project.

 

Regards,

Ronny G

Hi Ronny,

 

I understand your point completely. But from my point of view, I am actually not asking Intel to support any 3rd part application. I just need Intel to provide me the Firmware version information, so that I can find a right acpica-tools to work with. 

 

acpica-tools' changes are reflecting the changes of ACPI tables format.  I can see ACPI 6.0 till 6.4 from ACPICA change log (https://acpica.org/sites/acpica/files/changes_59.txt).  What I need to know is which ACPI table format the NUC firmware is following.

 

It will be very helpful if you could tell me which acpica-tools is working with the firmware, but this is not the essence of the request.

 

Hope this can help your justification.

Thank you

Harry

Hi @harwang,

 

I just got confirmation that we don't have the ACPI information readily available for customers. Find attached (NUC8PN_ACPI Dev.txt) the ACPI configuration for NUC8PN obtained by using a 3rd party utility "HWInfo64".

Keep in mind that that this tool is not developed, managed, or supported by Intel hence we are unable to make changes if required. 

 

I hope this helps,

Ronny G
