Regarding #366, I have Celeron(R) CPU N3150, architecture shows Atom/Airmont.

Is there anything that I can help?

I believe we should rather read "Braswell" ?

EDIT: Fixed and available in the develop branch for your testings.

Can you create a new issue Celeron(R) CPU N3150 then post details from CoreFreq:

corefreq-cli -s -n -m -n -B -n -M -n -C 1

Spreadtrum SC9853I CPUID 06_75 perhaps Airmont compatible ?

Edit: done.

As mentioned in "epyc-embedded-9004-series-product-brief" FOOTNOTES, I'm looking for "Socket SP5/SP6 Platform RAS Specification and Implementation Guide for Family 19h Model 10-1Fh" from devhub.amd.com/wp-content/uploads/Docs/57065_0.95.pdf

Anyone ?

Refering to those issues; the remaining actions are:

• Decode geometry of new 24 and 48 GB DIMM.
• Find registers for unknown power values
• Solve TjMax and offset values
• Debug detection of IOMMU

Activity Monitors Unit (AMU)

• CPU cycle counter: increments at the frequency of the CPU.
• Constant counter: increments at the fixed frequency of the system clock.
• Instructions retired
• Memory stall cycles

When in WFI or WFE these counters do not increment.
