Struct Data 

pub struct Data(/* private fields */);

OPP data.

Rust abstraction for the C struct dev_pm_opp_data, used to define operating performance points (OPPs) dynamically.

Examples

The following example demonstrates how to create an OPP with Data.

use kernel::clk::Hertz;
use kernel::device::Device;
use kernel::error::Result;
use kernel::opp::{Data, MicroVolt, Token};
use kernel::sync::aref::ARef;

fn create_opp(dev: &ARef<Device>, freq: Hertz, volt: MicroVolt, level: u32) -> Result<Token> {
    let data = Data::new(freq, volt, level, false);

    // OPP is removed once token goes out of scope.
    data.add_opp(dev)
}

Implementations

impl Data

pub fn new(freq: Hertz, volt: MicroVolt, level: u32, turbo: bool) -> Self

Creates a new instance of Data.

This can be used to define a dynamic OPP to be added to a device.

pub fn add_opp(self, dev: &ARef<Device>) -> Result<Token>

Adds an OPP dynamically.

Returns a Token that ensures the OPP is automatically removed when it goes out of scope.
