Implementations§

source§

impl PmConfig

source

pub fn new(no_soft_reset: bool) -> Self

source

pub fn read(&self, data: &mut u32)

source

pub fn write(&mut self, offset: u64, data: &[u8])

source

pub fn should_trigger_pme(&mut self) -> bool

If device is in D3 and PME is enabled, set PME status, then device could inject a pme interrupt into guest

source

pub fn get_power_status(&self) -> PciDevicePower

Get device power status

Trait Implementations§

source§

impl PciCapConfig for PmConfig

source§

fn read_mask(&self) -> &'static [u32]

Returns the read mask used by read_reg.
source§

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

Reads a 32bit register from the capability. Only the bits set in the read mask will be used, while the rest of the bits will be taken from the PciConfiguration’s register data. reg_idx - index into the capability
source§

fn write_reg( &mut self, reg_idx: usize, offset: u64, data: &[u8] ) -> Option<Box<dyn PciCapConfigWriteResult>>

Writes data to the capability. reg_idx - index into PciConfiguration.registers. offset - PciConfiguration.registers is in unit of DWord, offset define byte offset in the DWord. data - The data to write.
source§

fn set_cap_mapping(&mut self, mapping: PciCapMapping)

Used to pass the mmio region for the capability to the implementation. If any external events update the capability’s registers, then PciCapMapping.set_reg must be called to make the changes visible to the guest.
source§

fn num_regs(&self) -> usize

§

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

where T: Any + Send + Sync,

§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Send + Sync>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
