Member Function Documentation

◆ active()

bool ArmInterruptPin::active ( ) const

inline

True if interrupt pin is active, false otherwise.

uint32_t ArmInterruptPin::num ( ) const

inline

Get interrupt number.

Definition at line 194 of file base_gic.hh.

References intNum.

Referenced by Gicv3CPUInterface::setThreadContext(), and Gicv3CPUInterface::virtualUpdate().

◆ raise()

virtual void ArmInterruptPin::raise ( )

pure virtual

◆ serialize()

void ArmInterruptPin::serialize ( CheckpointOut & cp ) const

overridevirtual

Serialize an object.

Output an object's state into the current checkpoint section.

Parameters

cp	Checkpoint state

Implements Serializable.

Definition at line 147 of file base_gic.cc.

References _active, and SERIALIZE_SCALAR.

◆ setThreadContext()

void ArmInterruptPin::setThreadContext ( ThreadContext * tc )

Set the thread context owning this interrupt.

This method is used to set the thread context for interrupts that are thread/CPU-specific. Only devices that are used in such a context are expected to call this method.

Definition at line 130 of file base_gic.cc.

References panic_if, and threadContext.

◆ targetContext()

ContextID ArmInterruptPin::targetContext ( ) const

protected

Get the target context ID of this interrupt.

Precondition: setThreadContext() must have been called prior to calling this method.

Definition at line 139 of file base_gic.cc.

References ThreadContext::contextId(), panic_if, and threadContext.

Referenced by ArmPPI::clear(), and ArmPPI::raise().

◆ unserialize()

void ArmInterruptPin::unserialize ( CheckpointIn & cp )

overridevirtual

Unserialize an object.

Read an object's state from the current checkpoint section.

Parameters

cp	Checkpoint state

Implements Serializable.

Definition at line 153 of file base_gic.cc.
