Member Function Documentation

◆ clearConsoleInt()

void Tsunami::clearConsoleInt ( )

overridevirtual

Clear a posted CPU interrupt.

Implements Platform.

Definition at line 71 of file tsunami.cc.

References TsunamiIO::clearPIC(), and io.

◆ clearPciInt()

void Tsunami::clearPciInt ( int line )

overridevirtual

Clear a posted PCI->CPU interrupt.

Reimplemented from Platform.

Definition at line 83 of file tsunami.cc.

References cchip, and TsunamiCChip::clearDRIR().

◆ init()

void Tsunami::init ( )

overridevirtual

init() is called after all C++ SimObjects have been created and all ports are connected.

Initializations that are independent of unserialization but rely on a fully instantiated and connected SimObject graph should be done here.

Reimplemented from SimObject.

Definition at line 57 of file tsunami.cc.

References TsunamiIO::frequency(), io, AlphaSystem::setIntrFreq(), and system.

◆ postConsoleInt()

void Tsunami::postConsoleInt ( )

overridevirtual

Cause the cpu to post a serial interrupt to the CPU.

Implements Platform.

Definition at line 65 of file tsunami.cc.

References io, and TsunamiIO::postPIC().

◆ postPciInt()

void Tsunami::postPciInt ( int line )

overridevirtual

Cause the chipset to post a cpi interrupt to the CPU.

Reimplemented from Platform.

Definition at line 77 of file tsunami.cc.

References cchip, and TsunamiCChip::postDRIR().

◆ serialize()

void Tsunami::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 89 of file tsunami.cc.

References intr_sum_type, Max_CPUs, and SERIALIZE_ARRAY.

◆ unserialize()

void Tsunami::unserialize ( CheckpointIn & cp )

overridevirtual

Unserialize an object.

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

Parameters

cp	Checkpoint state

Implements Serializable.
