Package: src:linux 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 setThis 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.
config INTEL_PMC_CORE tristate "Intel PMC Core driver" depends on PCI help The Intel Platform Controller Hub for Intel Core SoCs provides access to Power Management Controller registers via a PCI interface. This driver can utilize debugging capabilities and supported features as exposed by the Power Management Controller. Supported features: - SLP_S0_RESIDENCY counter - PCH IP Power Gating status - LTR Ignore - MPHY/PLL gating status (Sunrisepoint PCH only)
Kind regards, Paul
