Struct DevicePowerManager

pub struct DevicePowerManager {
    domains: Mutex<BTreeMap<usize, PowerDomain>>,
}

A device container for routing PM requests.

Fields

domains: Mutex<BTreeMap<usize, PowerDomain>>

Implementations

impl DevicePowerManager

pub fn new() -> Self

pub fn attach( &mut self, device: Arc<Mutex<dyn BusDevice>>, domain_id: usize, ) -> Result<()>

Add a device to a power domain; domain IDs are abstract values managed by the caller.

Fails if the device’s initial state does not match other devices in the power domain.

pub fn power_on(&self, domain_id: usize) -> Result<()>

Powers all devices contained in a domain on.

pub fn power_off(&self, domain_id: usize) -> Result<()>

Powers all devices contained in a domain off.
