Inheritance diagram for gem5::LdsState::TickEvent:

Public Member Functions
	TickEvent (LdsState *_ldsState)
virtual void	process ()
	wake up at this time and perform specified actions
void	schedule (Tick when)
void	deschedule ()
Public Member Functions inherited from gem5::Event
	Event (Priority p=Default_Pri, Flags f=0)
bool	scheduled () const
	Determine if the current event is scheduled.
void	squash ()
	Squash the current event.
bool	squashed () const
	Check whether the event is squashed.
bool	isExitEvent () const
	See if this is a SimExitEvent (without resorting to RTTI)
bool	isManaged () const
	Check whether this event will auto-delete.
bool	isAutoDelete () const
	The function returns true if the object is automatically deleted after the event is processed.
Tick	when () const
	Get the time that the event is scheduled.
Priority	priority () const
	Get the event priority.
virtual BaseGlobalEvent *	globalEvent ()
	If this is part of a GlobalEvent, return the pointer to the Global Event.
void	serialize (CheckpointOut &cp) const override
	Serialize an object.
void	unserialize (CheckpointIn &cp) override
	Unserialize an object.
virtual	~Event ()
virtual const std::string	name () const
virtual const char *	description () const
	Return a C string describing the event.
void	dump () const
	Dump the current event data.
Public Member Functions inherited from gem5::Serializable
	Serializable ()
virtual	~Serializable ()
void	serializeSection (CheckpointOut &cp, const char *name) const
	Serialize an object into a new section.
void	serializeSection (CheckpointOut &cp, const std::string &name) const
void	unserializeSection (CheckpointIn &cp, const char *name)
	Unserialize an a child object.
void	unserializeSection (CheckpointIn &cp, const std::string &name)

Additional Inherited Members
Public Types inherited from gem5::EventBase
typedef int8_t	Priority
Static Public Member Functions inherited from gem5::Serializable
static const std::string &	currentSection ()
	Gets the fully-qualified name of the active section.
static void	generateCheckpointOut (const std::string &cpt_dir, std::ofstream &outstream)
	Generate a checkpoint file so that the serialization can be routed to it.
Static Public Attributes inherited from gem5::EventBase
static const Priority	Minimum_Pri = SCHAR_MIN
	Event priorities, to provide tie-breakers for events scheduled at the same cycle.
static const Priority	Debug_Enable_Pri = -101
	If we enable tracing on a particular cycle, do that as the very first thing so we don't miss any of the events on that cycle (even if we enter the debugger).
static const Priority	Debug_Break_Pri = -100
	Breakpoints should happen before anything else (except enabling trace output), so we don't miss any action when debugging.
static const Priority	CPU_Switch_Pri = -31
	CPU switches schedule the new CPU's tick event for the same cycle (after unscheduling the old CPU's tick event).
static const Priority	Delayed_Writeback_Pri = -1
	For some reason "delayed" inter-cluster writebacks are scheduled before regular writebacks (which have default priority).
static const Priority	Default_Pri = 0
	Default is zero for historical reasons.
static const Priority	DVFS_Update_Pri = 31
	DVFS update event leads to stats dump therefore given a lower priority to ensure all relevant states have been updated.
static const Priority	Serialize_Pri = 32
	Serailization needs to occur before tick events also, so that a serialize/unserialize is identical to an on-line CPU switch.
static const Priority	CPU_Tick_Pri = 50
	CPU ticks must come after other associated CPU events (such as writebacks).
static const Priority	CPU_Exit_Pri = 64
	If we want to exit a thread in a CPU, it comes after CPU_Tick_Pri.
static const Priority	Stat_Event_Pri = 90
	Statistics events (dump, reset, etc.) come after everything else, but before exit.
static const Priority	Progress_Event_Pri = 95
	Progress events come at the end.
static const Priority	Sim_Exit_Pri = 100
	If we want to exit on this cycle, it's the very last thing we do.
static const Priority	Maximum_Pri = SCHAR_MAX
	Maximum priority.
Protected Types inherited from gem5::EventBase
typedef unsigned short	FlagsType
typedef ::gem5::Flags< FlagsType >	Flags
Protected Member Functions inherited from gem5::Event
Flags	getFlags () const
bool	isFlagSet (Flags _flags) const
void	setFlags (Flags _flags)
void	clearFlags (Flags _flags)
void	clearFlags ()
virtual void	trace (const char *action)
	This function isn't really useful if TRACING_ON is not defined.
const std::string	instanceString () const
	Return the instance number as a string.
void	acquire ()
	Memory management hooks for events that have the Managed flag set.
void	release ()
	Managed event removed from the event queue.
virtual void	acquireImpl ()
virtual void	releaseImpl ()

static const FlagsType	Scheduled = 0x0002
static const FlagsType	Managed = 0x0004
