Do not enable intel_pstate as the default
scaling driver for the supported processors
++ + force
++ + Enable intel_pstate on systems that prohibit it by default
++ + in favor of acpi-cpufreq. Forcing the intel_pstate driver
++ + instead of acpi-cpufreq may disable platform features, such
++ + as thermal controls and power capping, that rely on ACPI
++ + P-States information being indicated to OSPM and therefore
++ + should be used with caution. This option does not work with
++ + processors that aren't supported by the intel_pstate driver
++ + or on platforms that use pcc-cpufreq instead of acpi-cpufreq.
+ + no_hwp
+ + Do not enable hardware P state control (HWP)
+ + if available.
