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 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.
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
