200 * DOC: power_dpm_force_performance_level
202 * The amdgpu driver provides a sysfs API for adjusting certain power
203 * related parameters. The file power_dpm_force_performance_level is
204 * used for this. It accepts the following arguments:
224 * When auto is selected, the driver will attempt to dynamically select
225 * the optimal power profile for current conditions in the driver.
229 * When low is selected, the clocks are forced to the lowest power state.
233 * When high is selected, the clocks are forced to the highest power state.
237 * When manual is selected, the user can manually adjust which power states
238 * are enabled for each clock domain via the sysfs pp_dpm_mclk, pp_dpm_sclk,
239 * and pp_dpm_pcie files and adjust the power state transition heuristics
240 * via the pp_power_profile_mode sysfs file.
247 * When the profiling modes are selected, clock and power gating are
248 * disabled and the clocks are set for different profiling cases. This
249 * mode is recommended for profiling specific work loads where you do
250 * not want clock or power gating for clock fluctuation to interfere
251 * with your results. profile_standard sets the clocks to a fixed clock
252 * level which varies from asic to asic. profile_min_sclk forces the sclk
253 * to the lowest level. profile_min_mclk forces the mclk to the lowest level.
254 * profile_peak sets all clocks (mclk, sclk, pcie) to the highest levels.

603 * Note that the actual memory controller clock rate are exposed, not
604 * the effective memory clock of the DRAMs. To translate it, use the
607 * Clock conversion (Mhz):
609 * HBM: effective_memory_clock = memory_controller_clock * 1
611 * G5: effective_memory_clock = memory_controller_clock * 1
613 * G6: effective_memory_clock = memory_controller_clock * 2
615 * DRAM data rate (MT/s):
617 * HBM: effective_memory_clock * 2 = data_rate
619 * G5: effective_memory_clock * 4 = data_rate
621 * G6: effective_memory_clock * 8 = data_rate
625 * data_rate * vram_bit_width / 8 = memory_bandwidth
631 * memory_controller_clock = 1750 Mhz
633 * effective_memory_clock = 1750 Mhz * 1 = 1750 Mhz
635 * data rate = 1750 * 4 = 7000 MT/s
637 * memory_bandwidth = 7000 * 128 bits / 8 = 112000 MB/s
641 * memory_controller_clock = 875 Mhz
643 * effective_memory_clock = 875 Mhz * 2 = 1750 Mhz
645 * data rate = 1750 * 8 = 14000 MT/s
647 * memory_bandwidth = 14000 * 256 bits / 8 = 448000 MB/s
649 * < For Vega10 and previous ASICs >
651 * Reading the file will display:
653 * - a list of engine clock levels and voltages labeled OD_SCLK
655 * - a list of memory clock levels and voltages labeled OD_MCLK
657 * - a list of valid ranges for sclk, mclk, and voltage labeled OD_RANGE
659 * To manually adjust these settings, first select manual using
660 * power_dpm_force_performance_level. Enter a new value for each
661 * level by writing a string that contains "s/m level clock voltage" to
662 * the file. E.g., "s 1 500 820" will update sclk level 1 to be 500 MHz
663 * at 820 mV; "m 0 350 810" will update mclk level 0 to be 350 MHz at
664 * 810 mV. When you have edited all of the states as needed, write
665 * "c" (commit) to the file to commit your changes. If you want to reset to the
666 * default power levels, write "r" (reset) to the file to reset them.
669 * < For Vega20 and newer ASICs >
671 * Reading the file will display:
673 * - minimum and maximum engine clock labeled OD_SCLK
675 * - minimum(not available for Vega20 and Navi1x) and maximum memory
676 * clock labeled OD_MCLK
678 * - three <frequency, voltage> points labeled OD_VDDC_CURVE.
679 * They can be used to calibrate the sclk voltage curve.
681 * - voltage offset(in mV) applied on target voltage calculation.
682 * This is available for Sienna Cichlid, Navy Flounder and Dimgrey
683 * Cavefish. For these ASICs, the target voltage calculation can be
684 * illustrated by "voltage = voltage calculated from v/f curve +
685 * overdrive vddgfx offset"
687 * - a list of valid ranges for sclk, mclk, and voltage curve points
692 * Reading the file will display:
694 * - minimum and maximum engine clock labeled OD_SCLK
696 * - a list of valid ranges for sclk labeled OD_RANGE
700 * Reading the file will display:
702 * - minimum and maximum engine clock labeled OD_SCLK
703 * - minimum and maximum core clocks labeled OD_CCLK
705 * - a list of valid ranges for sclk and cclk labeled OD_RANGE
707 * To manually adjust these settings:
709 * - First select manual using power_dpm_force_performance_level
711 * - For clock frequency setting, enter a new value by writing a
712 * string that contains "s/m index clock" to the file. The index
713 * should be 0 if to set minimum clock. And 1 if to set maximum
714 * clock. E.g., "s 0 500" will update minimum sclk to be 500 MHz.
715 * "m 1 800" will update maximum mclk to be 800Mhz. For core
716 * clocks on VanGogh, the string contains "p core index clock".
717 * E.g., "p 2 0 800" would set the minimum core clock on core
720 * For sclk voltage curve, enter the new values by writing a
721 * string that contains "vc point clock voltage" to the file. The
722 * points are indexed by 0, 1 and 2. E.g., "vc 0 300 600" will
723 * update point1 with clock set as 300Mhz and voltage as
724 * 600mV. "vc 2 1000 1000" will update point3 with clock set
725 * as 1000Mhz and voltage 1000mV.

3029 * - GPU temperature (via the on-die sensor)
3033 * - Northbridge voltage (APUs only)
3039 * - GPU gfx/compute engine clock
3041 * - GPU memory clock (dGPU only)
3043 * hwmon interfaces for GPU temperature:
3045 * - temp[1-3]_input: the on die GPU temperature in millidegrees Celsius
3046 * - temp2_input and temp3_input are supported on SOC15 dGPUs only
3048 * - temp[1-3]_label: temperature channel label
3049 * - temp2_label and temp3_label are supported on SOC15 dGPUs only
3051 * - temp[1-3]_crit: temperature critical max value in millidegrees Celsius
3052 * - temp2_crit and temp3_crit are supported on SOC15 dGPUs only
3054 * - temp[1-3]_crit_hyst: temperature hysteresis for critical limit in millidegrees Celsius
3055 * - temp2_crit_hyst and temp3_crit_hyst are supported on SOC15 dGPUs only
3057 * - temp[1-3]_emergency: temperature emergency max value(asic shutdown) in millidegrees Celsius
3058 * - these are supported on SOC15 dGPUs only
3060 * hwmon interfaces for GPU voltage:
3062 * - in0_input: the voltage on the GPU in millivolts
3064 * - in1_input: the voltage on the Northbridge in millivolts
3066 * hwmon interfaces for GPU power:
3068 * - power1_average: average power used by the GPU in microWatts
3070 * - power1_cap_min: minimum cap supported in microWatts
3072 * - power1_cap_max: maximum cap supported in microWatts
3074 * - power1_cap: selected power cap in microWatts
3076 * hwmon interfaces for GPU fan:
3078 * - pwm1: pulse width modulation fan level (0-255)
3080 * - pwm1_enable: pulse width modulation fan control method (0: no fan speed control, 1: manual fan speed control using pwm interface, 2: automatic fan speed control)
3082 * - pwm1_min: pulse width modulation fan control minimum level (0)
3084 * - pwm1_max: pulse width modulation fan control maximum level (255)
3086 * - fan1_min: a minimum value Unit: revolution/min (RPM)
3088 * - fan1_max: a maximum value Unit: revolution/max (RPM)
3090 * - fan1_input: fan speed in RPM
3092 * - fan[1-\*]_target: Desired fan speed Unit: revolution/min (RPM)
3094 * - fan[1-\*]_enable: Enable or disable the sensors.1: Enable 0: Disable
3096 * NOTE: DO NOT set the fan speed via "pwm1" and "fan[1-\*]_target" interfaces at the same time.
3097 * That will get the former one overridden.
3099 * hwmon interfaces for GPU clocks:
3101 * - freq1_input: the gfx/compute clock in hertz
3103 * - freq2_input: the memory clock in hertz
3105 * You can use hwmon tools like sensors to view this information on your system.
