Active mode for amd-pstate has shown enough success now that it makes sense
to enable it by default on client systems.
This series introduces a new kernel configuration option to set the default
policy for amd-pstate modes for a kernel.
Server systems will by identified by the PM preferred profile and still be
set as disabled by default for now.
changes from v1:
* fix the 0-DAY CI Kernel build error for acpi_pm_profile_server()
function, add CONFIG_ACPI check.
Mario Limonciello (4):
ACPI: CPPC: Add a symbol to check if the preferred profile is a server
cpufreq: amd-pstate: Set a fallback policy based on preferred_profile
cpufreq: amd-pstate: Add a kernel config option to set default mode
cpufreq: intel_pstate: Use the acpi_pm_profile_server() symbol
