 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) | |

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. | |

| 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 | Managed = 0x0004 |
| static const FlagsType | AutoDelete = Managed |
| static const FlagsType | Reserved0 = 0x0008 |
| This used to be AutoSerialize. | |
