If both are built-in, acpi-cpufreq uses late_initcall() and intel_pstate uses device_initcall() so it will be able to register as the scaling before acpi-cpufreq for the processors supported by intel_pstate. If acpi-cpufreq is built as a module then intel_pstate still gets first option to become the scaling driver. Signed-off-by: Dirk Brandewie Acked-by: Viresh Kumar Signed-off-by: Rafael J.
