Member Function Documentation

◆ active()

bool gem5::ArmInterruptPin::active ( ) const

inline

True if interrupt pin is active, false otherwise.

Definition at line 219 of file base_gic.hh.

References _active.

◆ clear()

virtual void gem5::ArmInterruptPin::clear ( )

pure virtual

Clear a signalled interrupt.

Implemented in gem5::ArmPPI, gem5::ArmSigInterruptPin, and gem5::ArmSPI.

◆ num()

uint32_t gem5::ArmInterruptPin::num ( ) const

inline

Get interrupt number.

Definition at line 216 of file base_gic.hh.

References intNum.

Referenced by ArmInterruptPin().

◆ raise()

virtual void gem5::ArmInterruptPin::raise ( )

pure virtual

Signal an interrupt.

Implemented in gem5::ArmPPI, gem5::ArmSigInterruptPin, and gem5::ArmSPI.

◆ serialize()

void gem5::ArmInterruptPin::serialize ( CheckpointOut & cp ) const

overridevirtual

Serialize an object.

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

Parameters

cp	Checkpoint state

Implements gem5::Serializable.

Definition at line 177 of file base_gic.cc.

References _active, and SERIALIZE_SCALAR.

◆ setThreadContext()

void gem5::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.
