The power_dpm_state file is a legacy interface and is only provided forīackwards compatibility. GPU power controls are exposed via sysfs files. You can use hwmon tools like sensors to view this information on your system. NOTE: DO NOT set the fan speed via 'pwm1' and 'fan_target' interfaces at the same time.įreq1_input: the gfx/compute clock in hertz Pwm1_max: pulse width modulation fan control maximum level (255)įan1_min: a minimum value Unit: revolution/min (RPM)įan1_max: a maximum value Unit: revolution/max (RPM)įan_target: Desired fan speed Unit: revolution/min (RPM)įan_enable: Enable or disable the sensors.1: Enable 0: Disable Pwm1_min: pulse width modulation fan control minimum level (0) 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) Pwm1: pulse width modulation fan level (0-255) Power1_cap: selected power cap in microWatts Power1_cap_max: maximum cap supported in microWatts Power1_cap_min: minimum cap supported in microWatts Power1_average: average power used by the SoC in microWatts. In1_input: the voltage on the Northbridge in millivolts In0_input: the voltage on the GPU in millivolts these are supported on SOC15 dGPUs only Temp_emergency: temperature emergency max value(asic shutdown) in millidegrees Celsius temp2_crit_hyst and temp3_crit_hyst are supported on SOC15 dGPUs only Temp_crit_hyst: temperature hysteresis for critical limit in millidegrees Celsius temp2_crit and temp3_crit are supported on SOC15 dGPUs only Temp_crit: temperature critical max value in millidegrees Celsius temp2_label and temp3_label are supported on SOC15 dGPUs only temp2_input and temp3_input are supported on SOC15 dGPUs only

Temp_input: the on die GPU temperature in millidegrees Celsius
