/**

 * DOC: power_dpm_force_performance_level

 *

 * The amdgpu driver provides a sysfs API for adjusting certain power

 * related parameters.  The file power_dpm_force_performance_level is

 * used for this.  It accepts the following arguments:

 * - auto

 * - low

 * - high

 * - manual

 * - GPU fan

 * - profile_standard

 * - profile_min_sclk

 * - profile_min_mclk

 * - profile_peak

 *

 * auto

 *

 * When auto is selected, the driver will attempt to dynamically select

 * the optimal power profile for current conditions in the driver.

 *

 * low

 *

 * When low is selected, the clocks are forced to the lowest power state.

 *

 * high

 *

 * When high is selected, the clocks are forced to the highest power state.

 *

 * manual

 *

 * When manual is selected, the user can manually adjust which power states

 * are enabled for each clock domain via the sysfs pp_dpm_mclk, pp_dpm_sclk,

 * and pp_dpm_pcie files and adjust the power state transition heuristics

 * via the pp_power_profile_mode sysfs file.

 *

 * profile_standard

 * profile_min_sclk

 * profile_min_mclk

 * profile_peak

 *

 * When the profiling modes are selected, clock and power gating are

 * disabled and the clocks are set for different profiling cases. This

 * mode is recommended for profiling specific work loads where you do

 * not want clock or power gating for clock fluctuation to interfere

 * with your results. profile_standard sets the clocks to a fixed clock

 * level which varies from asic to asic.  profile_min_sclk forces the sclk

 * to the lowest level.  profile_min_mclk forces the mclk to the lowest level.

 * profile_peak sets all clocks (mclk, sclk, pcie) to the highest levels.
