Public Types | |
| typedef int8_t | Priority |
Static Public Attributes | |
| 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 | CPU_Exit_Pri = 64 |
| If we want to exit a thread in a CPU, it comes after CPU_Tick_Pri. 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... | |
