Struct amdgpu_sysfs::gpu_handle::overdrive::vega20::Table

pub struct Table {
    pub current_sclk_range: Range,
    pub current_mclk_range: Range,
    pub vddc_curve: Vec<ClocksLevel>,
    pub voltage_offset: Option<i32>,
    pub od_range: OdRange,
}

Vega20 clocks table.

Fields

current_sclk_range: Range

The current core clock range.

current_mclk_range: Range

The current memory clock range.

vddc_curve: Vec<ClocksLevel>

The current voltage curve. May be empty if the GPU does not support it.

voltage_offset: Option<i32>

Voltage offset(in mV) applied on target voltage calculation. This is available for Sienna Cichlid, Navy Flounder and Dimgrey Cavefish.

od_range: OdRange

The allowed ranges for clockspeeds and voltages.

Implementations

impl Table

pub fn clear(&mut self)

Clears the table of all “applicable” values.

This removes all values except the allowed range. You can use it to avoid overwriting the table with already present values, as it can be problematic on some cards. It is intended to be used before calling set_* functions and generating commands/writing the table.

Sets the maximum core clock (without checking if it’s in the allowed range).

fn set_min_sclk_unchecked(&mut self, clockspeed: i32) -> Result<(), Error>

Sets the minimum core clock (without checking if it’s in the allowed range).

fn set_max_mclk_unchecked(&mut self, clockspeed: i32) -> Result<(), Error>

Sets the maximum memory clock (without checking if it’s in the allowed range).

fn set_min_mclk_unchecked(&mut self, clockspeed: i32) -> Result<(), Error>
