| Constructs a writeback event. More... | |
| void | process () |
| Processes the writeback event. More... | |
| const char * | description () const |
| Returns the description of this event. More... | |
 Public Member Functions inherited from Event | |
| Event (Priority p=Default_Pri, Flags f=0) | |
| virtual | ~Event () |
| virtual const std::string | name () const |
| void | dump () const |
| Dump the current event data. More... | |
| bool | scheduled () const |
| Determine if the current event is scheduled. More... | |
| void | squash () |
| Squash the current event. More... | |
| bool | squashed () const |
| Check whether the event is squashed. More... | |
| bool | isExitEvent () const |
| See if this is a SimExitEvent (without resorting to RTTI) More... | |
| bool | isManaged () const |
| Check whether this event will auto-delete. More... | |
| bool | isAutoDelete () const |
| Tick | when () const |
| Get the time that the event is scheduled. More... | |
| Priority | priority () const |
| Get the event priority. More... | |
| virtual BaseGlobalEvent * | globalEvent () |
| If this is part of a GlobalEvent, return the pointer to the Global Event. More... | |
| void | serialize (CheckpointOut &cp) const override |
| Serialize an object. More... | |
| void | unserialize (CheckpointIn &cp) override |
| Unserialize an object. More... | |
| Public Member Functions inherited from Serializable | |
| Serializable () | |
| virtual | ~Serializable () |
| void | serializeSection (CheckpointOut &cp, const char *name) const |
| Serialize an object into a new section. More... | |
| void | serializeSection (CheckpointOut &cp, const std::string &name) const |
| void | unserializeSection (CheckpointIn &cp, const char *name) |
| Unserialize an a child object. More... | |
| void | unserializeSection (CheckpointIn &cp, const std::string &name) |
Private Attributes | |
| DynInstPtr | inst |
| Instruction whose results are being written back. More... | |
| PacketPtr | pkt |
| The packet that would have been sent to memory. More... | |
| LSQUnit< Impl > * | lsqPtr |
| The pointer to the LSQ unit that issued the store. More... | |
Additional Inherited Members | |
| Public Types inherited from EventBase | |
| typedef int8_t | Priority |
| Static Public Member Functions inherited from Serializable | |
| static const std::string & | currentSection () |
| Get the fully-qualified name of the active section. More... | |
| static void | serializeAll (const std::string &cpt_dir) |
| static void | unserializeGlobals (CheckpointIn &cp) |
| Static Public Attributes inherited from EventBase | |
| static const Priority | Minimum_Pri = SCHAR_MIN |
| Event priorities, to provide tie-breakers for events scheduled at the same cycle. More... | |
| 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). More... | |
| 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. More... | |
| 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). More... | |
| static const Priority | Delayed_Writeback_Pri = -1 |
| For some reason "delayed" inter-cluster writebacks are scheduled before regular writebacks (which have default priority). More... | |
| static const Priority | Default_Pri = 0 |
| Default is zero for historical reasons. More... | |
| 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. More... | |
| 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. More... | |
| static const Priority | CPU_Tick_Pri = 50 |
| CPU ticks must come after other associated CPU events (such as writebacks). More... | |
| static const Priority | Stat_Event_Pri = 90 |
| Statistics events (dump, reset, etc.) come after everything else, but before exit. More... | |
| static const Priority | Progress_Event_Pri = 95 |
| Progress events come at the end. More... | |
| static const Priority | Sim_Exit_Pri = 100 |
| If we want to exit on this cycle, it's the very last thing we do. More... | |
| static const Priority | Maximum_Pri = SCHAR_MAX |
| Maximum priority. More... | |

| static int | ckptMaxCount = 0 |
| static int | ckptPrevCount = -1 |

| typedef ::Flags< FlagsType > | Flags |
| Protected Member Functions inherited from Event | |
| Flags | getFlags () const |
| Accessor for flags. More... | |
| bool | isFlagSet (Flags _flags) const |
| void | setFlags (Flags _flags) |
| Accessor for flags. More... | |

| void | clearFlags () |
| virtual void | trace (const char *action) |
| trace event activity More... | |

| Memory management hooks for events that have the Managed flag set. More... | |
| void | release () |
| Managed event removed from the event queue. More... | |
