Version: 5.8.10-1
Severity: normal

Dear Debian folks,


Currently, certain information regarding the Intel Power Management 
Controller is unaccessible, as the driver is not packaged by the Debian 
Linux kernel.

     $ grep INTEL_PMC_CORE /boot/config-5.8.0-2-amd64
     # CONFIG_INTEL_PMC_CORE is not set

This makes it harder to analyze, how power management works, why it 
often does not, like for example, why package C-State C10 is not reached 
on the Dell Latitude E7250.

It’d be great, if you selected `INTEL_PMC_CORE` in the configuration to 
build the driver.

>                 - LTR Ignore
>                 - MPHY/PLL gating status (Sunrisepoint PCH only)


Kind regards,

Paul
