source · pub struct PowerManagementDevice { /* private fields */ }
Expand description
A power management + ACPI device.
See the module level docs for more details.
Implementations§
source§impl PowerManagementDevice
impl PowerManagementDevice
sourcepub fn new(
action: PowerActionFn,
acpi_interrupt: LineInterrupt,
register_pio: &mut dyn RegisterPortIoIntercept,
vmtime: VmTimeAccess,
enable_acpi_mode: Option<EnableAcpiMode>,
pm_timer_assist: Option<Box<dyn PmTimerAssist>>,
) -> Self
pub fn new( action: PowerActionFn, acpi_interrupt: LineInterrupt, register_pio: &mut dyn RegisterPortIoIntercept, vmtime: VmTimeAccess, enable_acpi_mode: Option<EnableAcpiMode>, pm_timer_assist: Option<Box<dyn PmTimerAssist>>, ) -> Self
Create a new PowerManagementDevice
.
Most arguments to this constructor are self describing, though there are some that merit additional explanation:
action
: a callback invoked whenever the PM initiates a power eventpio_control
andpio_status
: define where in the port IO space the control/status registers get mapped to.enable_acpi_mode
: see the docs forEnableAcpiMode
sourcepub fn check_interrupt_assertion(&self)
pub fn check_interrupt_assertion(&self)
(used by the PIIX4 wrapper device)
Evaluates whether the power management (ACPI) interrupt should be asserted or de-asserted
If the state is out of sync with what it should be, this function will either assert or de-assert the interrupt. The logic for whether an ACPI interrupt should be sent is covered in various parts of Chapter 4 of any version of the ACPI spec.

sourcepub fn update_dynamic_pio_mappings(&mut self, pio_dynamic_addr: Option<u16>)
pub fn update_dynamic_pio_mappings(&mut self, pio_dynamic_addr: Option<u16>)
(used by the PIIX4 wrapper device)
Remap dynamic registers based on config in the PCI config space
sourcepub fn pcat_facp_acpi_enable(&mut self, enable: bool)
pub fn pcat_facp_acpi_enable(&mut self, enable: bool)
(used by the PIIX4 wrapper device)
See calling code in piix4_pm.rs for details on what this does.
sourcepub fn power_action(&mut self) -> &mut PowerActionFn
pub fn power_action(&mut self) -> &mut PowerActionFn
(used by the PIIX4 wrapper device)
Get a mutable reference to the provided PowerActionFn
