241 * The amdgpu driver provides a sysfs API for adjusting certain power
242 * related parameters. The file power_dpm_force_performance_level is
243 * used for this. It accepts the following arguments:
244 *

255 * - profile_min_sclk
256 *
257 * - profile_min_mclk
258 *
259 * - profile_peak
260 *
261 * auto
262 *
263 * When auto is selected, the driver will attempt to dynamically select
264 * the optimal power profile for current conditions in the driver.
265 *
266 * low
267 *
268 * When low is selected, the clocks are forced to the lowest power state.
269 *
270 * high
271 *
272 * When high is selected, the clocks are forced to the highest power state.
273 *
274 * manual
275 *
276 * When manual is selected, the user can manually adjust which power states
277 * are enabled for each clock domain via the sysfs pp_dpm_mclk, pp_dpm_sclk,
278 * and pp_dpm_pcie files and adjust the power state transition heuristics
279 * via the pp_power_profile_mode sysfs file.
280 *
281 * profile_standard
282 * profile_min_sclk
283 * profile_min_mclk
284 * profile_peak
285 *
286 * When the profiling modes are selected, clock and power gating are
287 * disabled and the clocks are set for different profiling cases. This
288 * mode is recommended for profiling specific work loads where you do
289 * not want clock or power gating for clock fluctuation to interfere
290 * with your results. profile_standard sets the clocks to a fixed clock
291 * level which varies from asic to asic. profile_min_sclk forces the sclk
292 * to the lowest level. profile_min_mclk forces the mclk to the lowest level.
293 * profile_peak sets all clocks (mclk, sclk, pcie) to the highest levels.

658 * DOC: pp_od_clk_voltage
659 *
660 * The amdgpu driver provides a sysfs API for adjusting the clocks and voltages
661 * in each power level within a power state. The pp_od_clk_voltage is used for
662 * this.
663 *
664 * < For Vega10 and previous ASICs >
665 *
666 * Reading the file will display:
667 *
668 * - a list of engine clock levels and voltages labeled OD_SCLK
669 *
670 * - a list of memory clock levels and voltages labeled OD_MCLK
671 *
672 * - a list of valid ranges for sclk, mclk, and voltage labeled OD_RANGE
673 *
674 * To manually adjust these settings, first select manual using
675 * power_dpm_force_performance_level. Enter a new value for each
676 * level by writing a string that contains "s/m level clock voltage" to
677 * the file. E.g., "s 1 500 820" will update sclk level 1 to be 500 MHz
678 * at 820 mV; "m 0 350 810" will update mclk level 0 to be 350 MHz at
679 * 810 mV. When you have edited all of the states as needed, write
680 * "c" (commit) to the file to commit your changes. If you want to reset to the
681 * default power levels, write "r" (reset) to the file to reset them.
682 *
683 *
684 * < For Vega20 >
685 *
686 * Reading the file will display:
687 *
688 * - minimum and maximum engine clock labeled OD_SCLK
689 *
690 * - maximum memory clock labeled OD_MCLK
691 *
692 * - three <frequency, voltage> points labeled OD_VDDC_CURVE.
693 * They can be used to calibrate the sclk voltage curve.
694 *
695 * - a list of valid ranges for sclk, mclk, and voltage curve points
696 * labeled OD_RANGE
697 *
698 * To manually adjust these settings:
699 *
700 * - First select manual using power_dpm_force_performance_level
701 *
702 * - For clock frequency setting, enter a new value by writing a
703 * string that contains "s/m index clock" to the file. The index
704 * should be 0 if to set minimum clock. And 1 if to set maximum
705 * clock. E.g., "s 0 500" will update minimum sclk to be 500 MHz.
706 * "m 1 800" will update maximum mclk to be 800Mhz.
707 *
708 * For sclk voltage curve, enter the new values by writing a
709 * string that contains "vc point clock voltage" to the file. The
710 * points are indexed by 0, 1 and 2. E.g., "vc 0 300 600" will
711 * update point1 with clock set as 300Mhz and voltage as
712 * 600mV. "vc 2 1000 1000" will update point3 with clock set
713 * as 1000Mhz and voltage 1000mV.
714 *
715 * - When you have edited all of the states as needed, write "c" (commit)
716 * to the file to commit your changes
717 *
718 * - If you want to reset to the default power levels, write "r" (reset)
719 * to the file to reset them

1543 * DOC: pp_power_profile_mode
1544 *
1545 * The amdgpu driver provides a sysfs API for adjusting the heuristics
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
