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.

Constructor & Destructor Documentation

◆ GlobalSimLoopExitEvent() [1/4]

gem5::GlobalSimLoopExitEvent::GlobalSimLoopExitEvent	(	Tick	when,
		const std::string &	_cause,
		int	c,
		Tick	repeat = 0,
		uint64_t	hypercall_id = 0,
		std::map< std::string, std::string >	payload = std::map<std::string, std::string>() )

The "old style" constructor for GlobalSimLoopExitEvent.

Not the type_id parameter is set to 0. Zero is reserved for the "old style" exitSimLoop handling via generators in the Simulator module. The payload is unused.

		uint64_t	hypercall_id,
		std::map< std::string, std::string >	payload = std::map<std::string, std::string>() )

The "new style" constructor for GlobalSimLoopExitEvent.

Here the "type_id" parameter is used to specify the type of the exit and the payload is used to pass additional information about the exit.

These are used to construct Exit Handlers on the Python side.
