Struct amdgpu_sysfs::gpu_controller::GpuController

pub struct GpuController {
    pub hw_monitors: Vec<HwMon>,
    // some fields omitted
}

A GpuController represents a handle over a single GPU device, as exposed in the Linux SysFS.

Fields

hw_monitors: Vec<HwMon>

A collection of all HwMons bound to this GPU. They are used to expose real-time data.

Implementations

impl GpuController

pub fn new_from_path(sysfs_path: PathBuf) -> Result<Self, GpuControllerError>

Initializes a new GpuController from a given SysFS device path.

Normally, the path should look akin to /sys/class/drm/card0/device, and it needs to at least contain a uevent file.

pub fn get_driver(&self) -> String

Gets the kernel driver used.

pub fn get_total_vram(&self) -> Option<u64>

Gets total VRAM size in bytes. May not be reported on some devices, such as integrated GPUs.

pub fn get_used_vram(&self) -> Option<u64>

Gets how much VRAM is currently used, in bytes. May not be reported on some devices, such as integrated GPUs.

pub fn get_busy_percent(&self) -> Option<u8>

Returns the GPU busy percentage.

pub fn get_vbios_version(&self) -> Option<String>

Returns the GPU VBIOS version. Empty if the GPU doesn’t report one.

Trait Implementations

impl Debug for GpuController

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl SysFS for GpuController

fn get_path(&self) -> &Path

fn read_file(&self, file: &str) -> Option<String>

Reads the content of a file in the SysFS.

fn write_file(&self, file: &str, contents: &str) -> Result<(), Error>

Write to a file in the SysFS.
