From: Mario Limonciello <mario.limonciello@xxxxxxx> Introduce a new profile type called 'custom' that can be set to allow changing settings outside of the standard profile settings. The idea behind this is to enforce a state machine so that a user can't set 'balanced' then manually change one APU setting and confuse userspace because the system is no longer really behaving in balanced. In practice the intention is that userspace would first set "custom" followed by modifying any settings. If userspace wants to go back to one of the predefined profiles then those profiles can be written to /sys/firmware/acpi/platform_profile.
