Maximum reported frequency is base frequency, not turbo frequency (Windows 11) #522

Open johanes2115 opened 1 year ago

johanes2115 commented 1 year ago

Dasharo version (if applicable) v1.7.0

Dasharo variant (if applicable) Novacustom

Affected component(s) or functionality (if applicable) CPU frequency testing

Brief summary

(Get-CimInstance CIM_Processor).MaxClockSpeed command returns base CPU frequency instead of max frequency, despite it being present in the SMBIOS.

Expected behaviour

The command mentioned above returns max CPU frequency, including turbo boost.

Actual behaviour

The command returns base clock speed.

mkopec commented 1 year ago

So the MaxClockSpeed object in the Win32_Processor takes its value from SMBIOS Type 4 data. We should have the maximum turbo clock speed in there: https://github.com/Dasharo/coreboot/blob/c1386ef6128922f49f93de5690ccd130a26eecf2/src/soc/intel/common/block/cpu/cpulib.c#L507 so the test should be valid. Needs some investigation.

@johanes2115 would you mind running sudo dmidecode on Ubuntu and copy the output here?

Also as we discussed offline, I changed the contents of the issue, as it seems to be a problem not with our documentation, but with the device itself @mkopec

@johanes2115 Is this issue still happening on Dasharo v1.5.2-rc1 (11th Gen) and Dasharo v1.7.2-rc1 (12th Gen)? https://github.com/Dasharo/coreboot/actions/runs/6907218746

Looks like we're only getting the static Current Speed value on Windows, not the correct Max Speed value that we need
