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

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 ()
