Additional Inherited Members
Public Types inherited from gem5::GlobalEvent
typedef BaseGlobalEventTemplate< GlobalEvent >	Base
Public Types inherited from gem5::EventBase
typedef int8_t	Priority
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.

Barrier	barrier
	The barrier that all threads wait on before performing the global event.

	The individual local event instances (one per thread/event queue).
