Implement more m5 pseduo opcodes:
resetstats dumpstats dumpresetstats m5checkpoint Lots of cleanup of serialization and stats dumping/resetting to work with these new instructions arch/alpha/isa_desc: Implement more m5 pseduo opcodes: resetstats dumpstats dumpresetstats m5checkpoint All of these functions take two optional parameters, the first is a delay, and the second is a period. The delay tells the simulator to wait the specified number of nanoseconds before triggering the event, the period tells the simulator to repeat the event with a specified frequency base/statistics.cc: base/statistics.hh: regReset RegResetCallback dev/disk_image.cc: serializeFilename -> CheckpointFile() sim/debug.cc: Move this debugging statement to sim_stats.cc sim/eventq.cc: Don't AutoDelete an event if it is scheduled since the process() function could potentially schedule the event again. sim/main.cc: DumpStatsEvent is now Statistics::SetupEvent(Dump, curTick) sim/serialize.cc: Change the serialize event so that it's possible to cause the event to repeat. Also make the priority such that the event happens just before the simulator would exit if both events were scheduled for the same cycle. get rid of the serializeFilename variable and provide a CheckpointFile() function. This function takes a basename that is set in the configuration, and appends the current cycle to the name so that multiple checkpoints can be dumped from the same simulation. Also, don't exit the simulation when a checkpoint file is dumped. sim/serialize.hh: serializeFilename -> CheckpointFile() SetupCheckpoint function to tell the simulator to prepare to checkpoint at a certain time with a certain period sim/sim_events.cc: DumpStatsEvent stuff gets move to sim_stats.(cc|hh) The context stuff gets moved into the already existing stats context in stat_context.cc sim/sim_events.hh: DumpStatsEvent stuff gets move to sim_stats.(cc|hh) sim/universe.cc: Provide some simple functions for converting times into ticks. These use floating point math to get as close as possible to the real values. Multipliers are set up ahead of time --HG-- extra : convert_revision : d06ef26a9237529a1e5060cb1ac2dcc04d4ec252
