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...

 Accessor for flags. More...
