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

 237 *
 238 * - profile_min_mclk
 239 *
 240 * - profile_peak
 241 *
 242 * auto
 243 *
 244 * When auto is selected, the driver will attempt to dynamically select
 245 * the optimal power profile for current conditions in the driver.
 246 *
 247 * low
 248 *
 249 * When low is selected, the clocks are forced to the lowest power state.
 250 *
 251 * high
 252 *
 253 * When high is selected, the clocks are forced to the highest power state.
 254 *
 255 * manual
 256 *
 257 * When manual is selected, the user can manually adjust which power states
 258 * are enabled for each clock domain via the sysfs pp_dpm_mclk, pp_dpm_sclk,
 259 * and pp_dpm_pcie files and adjust the power state transition heuristics
 260 * via the pp_power_profile_mode sysfs file.
 261 *
 262 * profile_standard
 263 * profile_min_sclk
 264 * profile_min_mclk
 265 * profile_peak
 266 *
 267 * When the profiling modes are selected, clock and power gating are
 268 * disabled and the clocks are set for different profiling cases. This
 269 * mode is recommended for profiling specific work loads where you do
 270 * not want clock or power gating for clock fluctuation to interfere
 271 * with your results. profile_standard sets the clocks to a fixed clock
 272 * level which varies from asic to asic.  profile_min_sclk forces the sclk
 273 * to the lowest level.  profile_min_mclk forces the mclk to the lowest level.
 274 * profile_peak sets all clocks (mclk, sclk, pcie) to the highest levels.

 576 * DOC: pp_od_clk_voltage
 577 *
 578 * The amdgpu driver provides a sysfs API for adjusting the clocks and voltages
 579 * in each power level within a power state.  The pp_od_clk_voltage is used for
 580 * this.
 581 *
 582 * < For Vega10 and previous ASICs >
 583 *
 584 * Reading the file will display:
 585 *
 586 * - a list of engine clock levels and voltages labeled OD_SCLK
 587 *
 588 * - a list of memory clock levels and voltages labeled OD_MCLK
 589 *
 590 * - a list of valid ranges for sclk, mclk, and voltage labeled OD_RANGE
 591 *
 592 * To manually adjust these settings, first select manual using
 593 * power_dpm_force_performance_level. Enter a new value for each
 594 * level by writing a string that contains "s/m level clock voltage" to
 595 * the file.  E.g., "s 1 500 820" will update sclk level 1 to be 500 MHz
 596 * at 820 mV; "m 0 350 810" will update mclk level 0 to be 350 MHz at
 597 * 810 mV.  When you have edited all of the states as needed, write
 598 * "c" (commit) to the file to commit your changes.  If you want to reset to the
 599 * default power levels, write "r" (reset) to the file to reset them.
 600 *
 601 *
 602 * < For Vega20 >
 603 *
 604 * Reading the file will display:
 605 *
 606 * - minimum and maximum engine clock labeled OD_SCLK
 607 *
 608 * - maximum memory clock labeled OD_MCLK
 609 *
 610 * - three <frequency, voltage> points labeled OD_VDDC_CURVE.
 611 *   They can be used to calibrate the sclk voltage curve.
 612 *
 613 * - a list of valid ranges for sclk, mclk, and voltage curve points
 614 *   labeled OD_RANGE
 615 *
 616 * To manually adjust these settings:
 617 *
 618 * - First select manual using power_dpm_force_performance_level
 619 *
 620 * - For clock frequency setting, enter a new value by writing a
 621 *   string that contains "s/m index clock" to the file. The index
 622 *   should be 0 if to set minimum clock. And 1 if to set maximum
 623 *   clock. E.g., "s 0 500" will update minimum sclk to be 500 MHz.
 624 *   "m 1 800" will update maximum mclk to be 800Mhz.
 625 *
 626 *   For sclk voltage curve, enter the new values by writing a
 627 *   string that contains "vc point clock voltage" to the file. The
 628 *   points are indexed by 0, 1 and 2. E.g., "vc 0 300 600" will
 629 *   update point1 with clock set as 300Mhz and voltage as
 630 *   600mV. "vc 2 1000 1000" will update point3 with clock set
 631 *   as 1000Mhz and voltage 1000mV.
 632 *
 633 * - When you have edited all of the states as needed, write "c" (commit)
 634 *   to the file to commit your changes
 635 *
 636 * - If you want to reset to the default power levels, write "r" (reset)
 637 *   to the file to reset them
