2003-12-22add support for simple character input via the system consoleNathan Binkert
dev/alpha_access.h: - use our standard types instead of this extra typedef - advance the ALPHA_ACCESS version since the interface has changed. *this means you need a new console binary* - shuffle a couple things around to pack the data structure a bit better - add a placeholder for character input dev/alpha_console.cc: Clean up the read code path a bit and add support for character input via the console Clean up the write path and use a switch instead of a bunch of if statements --HG-- extra : convert_revision : a1a5bc8fed9ec9c4c46548fdf79604661668b81a

Most notable is that the rundiff trace-output lossage is fixed! base/pollevent.cc: Use SA_RESTART to keep blocked write() calls from failing with EINTR when signals happen. base/trace.hh: Make TRACING_ON depend on NDEBUG not being set (instead of DEBUG being set) so m5.opt/m5.fast do what we want. util/rundiff: Print header lines showing file/cmd names. --HG-- extra : convert_revision : 4966814ad65aedb6d62a5a62a6ad3e3f326d61b8

arch/alpha/alpha_memory.cc: Rename md_mode_type to mode_type. arch/alpha/ev5.cc: simPalCheck() only gets called on correct path now, so there's no need to test misspeculating(). arch/alpha/isa_desc: Get privileged call_pall detection right this time (I hope). ExecContext::simPalCheck() and Annotate::Callpal() are now called only on non-speculative executions... this should fix the bogus pal-call stats we've been seeing (since these are incremented in simPalCheck()).

This lets us centralize priorities so we can see what's going on. - Shift serialize & cpu-switch events to happen before CPU ticks (to be consistent with starting new CPU on same cycle instead of next cycle). - Get rid of unnecessary bus stats reset callback. cpu/simple_cpu/simple_cpu.cc: sim/debug.cc: sim/eventq.hh: sim/serialize.cc: sim/sim_events.cc: sim/sim_events.hh: Switch events to use a priority enum instead of integers.

2003-12-11Stats & serialization tweaks & cleanup. Unserializing fromSteve Reinhardt
a checkpoint now gives identical results to running from scratch and doing at switchover at the same cycle! - CPUs start at cycle 0 again, not cycle 1. - curTick is now serialized & unserialized. - Stats get reset in main (before event loop). Since this is done after curTick is unserialized, simTicks gets set correctly for running from a checkpoint. - Simplify serialization to happen in a single pass. - s/Serializeable/Serializable/ arch/alpha/isa_traits.hh: dev/etherlink.hh: sim/eventq.cc: sim/eventq.hh: s/Serializeable/Serializable/ kern/tru64/tru64_system.cc: sim/process.cc: Make initial CPU activation on cycle 0 again (not 1). sim/main.cc: Reset stats before getting started.

Serialize & unserialize curTick.

2003-12-09Sweeping change in the stats package....again...Nathan Binkert
base/statistics.cc: - Merge the m5 display and simplescalar compatible display functions. - Use functors for the stats printing instead of functions. This gets rid of the very long argument lists and improves clarity. - Fix a bug in binning that caused an invalid allocation to occur. base/statistics.hh: - Instead of using a compile time variable to choose whether to print in ss compat mode, we use a runtime variable. This is how we'll choose python output. - There are no more virtual functions in the statistics themselves. All virtual functions have been moved into a secondary helper class. Every stat has an associated helper class that knows how to access certain variables in that stat. There is a hash_map from the stat to it's helper class data. This was done because the helper data is only used during setup, stats reset, and printing. All of which happen rarely, and you want to avoid any performance hit that you can. - To provide the name(), desc(), etc functions to classes so that the user can set various parameters to the stats class, a single class containing all of those functions was created. An odd trick was done to actually make this class derive from the stat class because a base class with no data actually does end up taking up space. - The detail namespace was removed for now. I'll put it back when the package is not in so much flux. - Standard deviation, and mean were added to all distribution stats. - There are several bugfixes and changes that aren't mentioned test/Makefile: Don't test sim_stats foo. test/stattest.cc: Don't test sim_stats foo. Fix bin usage so that it corresponds to the current usage. --HG-- extra : convert_revision : ce8d9a8d485a84d55799f253d851e83650684170
