1544  * The amdgpu driver provides a sysfs API for adjusting the heuristics
1545  * related to switching between power levels in a power state.  The file
1546  * pp_power_profile_mode is used for this.
1547  *
1548  * Reading this file outputs a list of all of the predefined power profiles
1549  * and the relevant heuristics settings for that profile.
1550  *
1551  * To select a profile or create a custom profile, first select manual using
1552  * power_dpm_force_performance_level.  Writing the number of a predefined
1553  * profile to pp_power_profile_mode will enable those heuristics.  To
1554  * create a custom set of heuristics, write a string of numbers to the file
1555  * starting with the number of the custom profile along with a setting
1556  * for each heuristic parameter.  Due to differences across asic families
1557  * the heuristic parameters vary from family to family.
