Implementations

impl ACPIPMResource

pub fn new( sci_evt: IrqLevelEvent, suspend_tube: Arc<Mutex<SendTube>>, exit_evt_wrtube: SendTube, acdc: Option<Arc<Mutex<AcAdapter>>> ) -> ACPIPMResource

Constructs ACPI Power Management Resouce.

pub fn start(&mut self)

Trait Implementations

impl Aml for ACPIPMResource

fn to_aml_bytes(&self, bytes: &mut Vec<u8>)

Translate an ACPI object into AML code and append to the vector buffer.

impl BusDevice for ACPIPMResource

fn device_id(&self) -> DeviceId

Returns a unique id per device type suitable for metrics gathering.

fn debug_label(&self) -> String

Returns a label suitable for debug output.

fn read(&mut self, info: BusAccessInfo, data: &mut [u8])

Reads at offset from this device

fn write(&mut self, info: BusAccessInfo, data: &[u8])

Writes at offset into this device

fn config_register_write( &mut self, reg_idx: usize, offset: u64, data: &[u8] ) -> ConfigWriteResult

Sets a register in the configuration space. Only used by PCI.

fn config_register_read(&self, reg_idx: usize) -> u32

Gets a register from the configuration space. Only used by PCI.

fn init_pci_config_mapping( &mut self, shmem: &SharedMemory, base: usize, len: usize ) -> bool

Provides a memory region to back MMIO access to the configuration space. If the device can keep the memory region up to date, then it should return true, after which no more calls to config_register_read will be made. Otherwise the device should return false.

fn virtual_config_register_write(&mut self, reg_idx: usize, value: u32)

Sets a register in the virtual config space. Only used by PCI.

fn virtual_config_register_read(&self, reg_idx: usize) -> u32

Gets a register from the virtual config space. Only used by PCI.

fn on_sandboxed(&mut self)

Invoked when the device is sandboxed.

fn get_ranges(&self) -> Vec<(BusRange, BusType)>

Gets a list of all ranges registered by this BusDevice.

fn destroy_device(&mut self)

Invoked when the device is destroyed

fn is_bridge(&self) -> Option<u8>

Returns the secondary bus number if this bus device is pci bridge

impl BusResumeDevice for ACPIPMResource

fn resume_imminent(&mut self)

notify the devices which are invoked before the VM resumes form suspend.

impl PmResource for ACPIPMResource

fn pwrbtn_evt(&mut self)

fn slpbtn_evt(&mut self)

fn rtc_evt(&mut self, clear_evt: Event)

fn gpe_evt(&mut self, gpe: u32, clear_evt: Option<Event>)

fn pme_evt(&mut self, requester_id: u16)

fn register_gpe_notify_dev( &mut self, gpe: u32, notify_dev: Arc<Mutex<dyn GpeNotify>> )

fn register_pme_notify_dev( &mut self, bus: u8, notify_dev: Arc<Mutex<dyn PmeNotify>> )

impl Serialize for ACPIPMResource

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Suspendable for ACPIPMResource

fn snapshot(&mut self) -> Result<Value>

Save the device state in an image that can be restored.

fn restore(&mut self, data: Value) -> Result<()>

Load a saved snapshot of an image.

fn sleep(&mut self) -> Result<()>

Stop all threads related to the device. Sleep should be idempotent.

fn wake(&mut self) -> Result<()>

Create/Resume all threads related to the device. Wake should be idempotent.
