Hello Felix Singer, build bot (Jenkins), Matt Delco, Nico Huber, Furquan Shaikh, Tim Wawrzynczak, Paul Menzel, Subrata Banik, Patrick Rudolph,
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/coreboot/+/46464
to look at the new patch set (#8).
Change subject: cpu/intel/common: correct MSR for the Nominal Performance in CPPC ......................................................................
cpu/intel/common: correct MSR for the Nominal Performance in CPPC
The "Nominal Performance" is not the same as the "Guaranteed Performance", but is defined as the performance a processor can deliver continously under ideal environmental conditions.
According to edk2, this is the "Maximum Non-Turbo Ratio", which needs to be read from MSR_PLATFORM_INFO instead of IA32_HWP_CAPABILITIES.
Correct the entry in the CPPC package.
Test: dumped SSDT from Supermicro X11SSM-F and checked decompiled version
