Struct amdgpu_sysfs::hw_mon::HwMon

pub struct HwMon { /* private fields */ }

Reprepesents a hardware monitor. Hardware monitors are used to report real-time information about the device, such as temperatures and power usage.

Implementations

impl HwMon

pub fn new_from_path(path: PathBuf) -> Result<Self, Error>

Most of the time you may want to access HwMons through the GpuHandle they’re bound to.

pub fn get_temps(&self) -> HashMap<String, Temperature>

Returns a HashMap of temperatures(in degress celsius), indexed by the labels (example: “edge”).

pub fn get_gpu_clockspeed(&self) -> Result<u64, Error>

Gets the current GFX/compute clockspeed in MHz.

pub fn get_vram_clockspeed(&self) -> Result<u64, Error>

Gets the current memory clockspeed in MHz.

pub fn get_power_average(&self) -> Result<f64, Error>

Gets the average power (currently) used by the GPU in watts.

pub fn get_power_cap(&self) -> Result<f64, Error>

Gets the current power cap of the GPU in watts.

pub fn set_power_cap(&self, cap: f64) -> Result<(), Error>

Sets the current power cap of the GPU in watts.

pub fn get_power_cap_max(&self) -> Result<f64, Error>

Gets the maximum possible power cap for the GPU in watts. If overclocking is disabled, this is probably the same as the default cap.

pub fn get_power_cap_min(&self) -> Result<f64, Error>

Gets the minimum possible power cap for the GPU in watts.

pub fn get_power_cap_default(&self) -> Result<f64, Error>

Gets the default power cap for the GPU in watts.

pub fn get_fan_pwm(&self) -> Result<u8, Error>

Gets the pulse width modulation fan level.

pub fn set_fan_pwm(&self, pwm: u8) -> Result<(), Error>

Sets the pulse width modulation fan level.

pub fn get_fan_current(&self) -> Result<u32, Error>

Gets the current fan speed in RPM.

pub fn get_fan_max(&self) -> Result<u32, Error>

Gets the maximum possible fan speed in RPM.

pub fn get_fan_min(&self) -> Result<u32, Error>

Gets the minimum possible fan speed in RPM.

pub fn get_fan_target(&self) -> Result<u32, Error>

Gets the currently desired fan speed in RPM.

pub fn set_fan_target(&self, target: u32) -> Result<(), Error>

Sets the desired fan speed in RPM.

pub fn get_fan_control_method(&self) -> Result<FanControlMethod, Error>

Gets the pulse width modulation control method.

pub fn set_fan_control_method(
    &self,
    method: FanControlMethod
) -> Result<(), Error>

Sets the fan control method (pwm1_enable).

pub fn get_gpu_voltage(&self) -> Result<u64, Error>

Gets the GPU voltage in millivolts.

pub fn get_northbridge_voltage(&self) -> Result<u64, Error>

Gets the north bridge voltage in millivolts.
