1546  * related to switching between power levels in a power state.  The file
1547  * pp_power_profile_mode is used for this.
1548  *
1549  * Reading this file outputs a list of all of the predefined power profiles
1550  * and the relevant heuristics settings for that profile.
1551  *
1552  * To select a profile or create a custom profile, first select manual using
1553  * power_dpm_force_performance_level.  Writing the number of a predefined
1554  * profile to pp_power_profile_mode will enable those heuristics.  To
1555  * create a custom set of heuristics, write a string of numbers to the file
1556  * starting with the number of the custom profile along with a setting
1557  * for each heuristic parameter.  Due to differences across asic families
1558  * the heuristic parameters vary from family to family.
