Member Function Documentation

void Root::initState ( )
overridevirtual

Schedule the timesync event at initState() when not unserializing.

Reimplemented from SimObject.

Definition at line 121 of file root.cc.

References params(), and timeSyncEnable().

void Root::loadState ( CheckpointIn cp)
overridevirtual

Schedule the timesync event at loadState() so that curTick is correct.

Reimplemented from SimObject.

Definition at line 127 of file root.cc.

References SimObject::loadState(), params(), and timeSyncEnable().

Referenced by initState(), and loadState().

static Root* Root::root ( )
inlinestatic

Use this function to get a pointer to the single Root object in the simulation.

This function asserts that such an object has actual been constructed to avoid having to perform that check everywhere the root is used. This is to allow calling the functions below.

Returns
Pointer to the single root object.

Definition at line 76 of file root.hh.

References _root.

void Root::serialize ( CheckpointOut cp) const
overridevirtual

Serialize an object.

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

Parameters
cpCheckpoint state

Implements Serializable.

Definition at line 134 of file root.cc.

References FullSystem, and SERIALIZE_SCALAR.

void Root::timeSync ( )
protected
void Root::timeSyncEnable ( bool  en)

Enable or disable time syncing.

Definition at line 72 of file root.cc.

References _enabled, _periodTick, curTick(), EventManager::deschedule(), ArmISA::en, EventManager::schedule(), and syncEvent.

Referenced by initState(), loadState(), timeSyncPeriod(), and timeSyncSpinThreshold().

bool Root::timeSyncEnabled ( ) const
inline

Check whether time syncing is enabled.

Definition at line 85 of file root.hh.

References _enabled.

Referenced by timeSyncPeriod(), and timeSyncSpinThreshold().

const Time Root::timeSyncPeriod ( ) const
inline

Retrieve the period for the sync event.

Definition at line 87 of file root.hh.

References _period.

void Root::timeSyncPeriod ( Time  newPeriod)

Configure the period for time sync events.

Definition at line 90 of file root.cc.

References _period, _periodTick, ArmISA::en, Time::getTick(), timeSyncEnable(), and timeSyncEnabled().

const Time Root::timeSyncSpinThreshold ( ) const
inline

Retrieve the threshold for time remaining to spin wait.

Definition at line 89 of file root.hh.

References _spinThreshold.

void Root::timeSyncSpinThreshold ( Time  newThreshold)

Set the threshold for time remaining to spin wait.

Definition at line 100 of file root.cc.

References _spinThreshold, ArmISA::en, timeSyncEnable(), and timeSyncEnabled().

void Root::unserialize ( CheckpointIn cp)
overridevirtual

Unserialize an object.

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

Parameters
cpCheckpoint state

Implements Serializable.
