From 29e34a739b991af8d8e1eafe75ecb0904c324dc8 Mon Sep 17 00:00:00 2001 From: Steve Reinhardt Date: Fri, 9 Jun 2006 23:01:31 -0400 Subject: Move main control from C++ into Python. User script now invokes initialization and simulation loop after building configuration. These functions are exported from C++ to Python using SWIG. SConstruct: Set up SWIG builder & scanner. Set up symlinking of source files into build directory (by not disabling the default behavior). configs/test/test.py: Rewrite to use new script-driven interface. Include a sample option. src/SConscript: Set up symlinking of source files into build directory (by not disabling the default behavior). Add SWIG-generated main_wrap.cc to source list. src/arch/SConscript: Set up symlinking of source files into build directory (by not disabling the default behavior). src/arch/alpha/ev5.cc: src/arch/alpha/isa/decoder.isa: src/cpu/o3/alpha_cpu_impl.hh: src/cpu/trace/opt_cpu.cc: src/cpu/trace/trace_cpu.cc: src/sim/pseudo_inst.cc: src/sim/root.cc: src/sim/serialize.cc: src/sim/syscall_emul.cc: SimExit() is now exitSimLoop(). src/cpu/base.cc: SimExitEvent is now SimLoopExitEvent src/python/SConscript: Add SWIG build command for main.i. Use python/m5 in build dir as source for zip archive... easy now with file duplication enabled. src/python/m5/__init__.py: - Move copyright notice back to C++ so we can print it right away, even for interactive sessions. - Get rid of argument parsing code; just provide default option descriptors for user script to call optparse with. - Don't clutter m5 namespace by sucking in all of m5.config and m5.objects. - Move instantiate() function here from config.py. src/python/m5/config.py: - Move instantiate() function to __init__.py. - Param.Foo deferred type lookups must use m5.objects namespace now (not m5). src/python/m5/objects/AlphaConsole.py: src/python/m5/objects/AlphaFullCPU.py: src/python/m5/objects/AlphaTLB.py: src/python/m5/objects/BadDevice.py: src/python/m5/objects/BaseCPU.py: src/python/m5/objects/BaseCache.py: src/python/m5/objects/Bridge.py: src/python/m5/objects/Bus.py: src/python/m5/objects/CoherenceProtocol.py: src/python/m5/objects/Device.py: src/python/m5/objects/DiskImage.py: src/python/m5/objects/Ethernet.py: src/python/m5/objects/Ide.py: src/python/m5/objects/IntrControl.py: src/python/m5/objects/MemObject.py: src/python/m5/objects/MemTest.py: src/python/m5/objects/Pci.py: src/python/m5/objects/PhysicalMemory.py: src/python/m5/objects/Platform.py: src/python/m5/objects/Process.py: src/python/m5/objects/Repl.py: src/python/m5/objects/Root.py: src/python/m5/objects/SimConsole.py: src/python/m5/objects/SimpleDisk.py: src/python/m5/objects/System.py: src/python/m5/objects/Tsunami.py: src/python/m5/objects/Uart.py: Fix up imports (m5 namespace no longer includes m5.config). src/sim/eventq.cc: src/sim/eventq.hh: Support for Python-called simulate() function: - Use IsExitEvent flag to signal events that want to exit the simulation loop gracefully (instead of calling exit() to terminate the process). - Modify interface to hand exit event object back to caller so it can be inspected for cause. src/sim/host.hh: Add MaxTick constant. src/sim/main.cc: Move copyright notice back to C++ so we can print it right away, even for interactive sessions. Use PYTHONPATH environment var to set module path (instead of clunky code injection method). Move main control from here into Python: - Separate initialization code and simulation loop into separate functions callable from Python. - Make Python interpreter invocation more pure (more like directly invoking interpreter). Add -i and -p flags (only options on binary itself; other options processed by Python). Import readline package when using interactive mode. src/sim/sim_events.cc: SimExitEvent is now SimLoopExitEvent, and uses IsSimExit flag to terminate loop (instead of exiting simulator process). src/sim/sim_events.hh: SimExitEvent is now SimLoopExitEvent, and uses IsSimExit flag to terminate loop (instead of exiting simulator process). Get rid of a few unused constructors. src/sim/sim_exit.hh: SimExit() is now exitSimLoop(). Get rid of unused functions. Add comments. --HG-- extra : convert_revision : 280b0d671516b25545a6f24cefa64a68319ff3d4 --- src/cpu/base.cc | 8 ++++---- src/cpu/o3/alpha_cpu_impl.hh | 2 +- src/cpu/trace/opt_cpu.cc | 2 +- src/cpu/trace/trace_cpu.cc | 2 +- 4 files changed, 7 insertions(+), 7 deletions(-) (limited to 'src/cpu') diff --git a/src/cpu/base.cc b/src/cpu/base.cc index 64d81ef4b..59324e537 100644 --- a/src/cpu/base.cc +++ b/src/cpu/base.cc @@ -93,8 +93,8 @@ BaseCPU::BaseCPU(Params *p) // if (p->max_insts_any_thread != 0) for (int i = 0; i < number_of_threads; ++i) - new SimExitEvent(comInstEventQueue[i], p->max_insts_any_thread, - "a thread reached the max instruction count"); + new SimLoopExitEvent(comInstEventQueue[i], p->max_insts_any_thread, + "a thread reached the max instruction count"); if (p->max_insts_all_threads != 0) { // allocate & initialize shared downcounter: each event will @@ -118,8 +118,8 @@ BaseCPU::BaseCPU(Params *p) // if (p->max_loads_any_thread != 0) for (int i = 0; i < number_of_threads; ++i) - new SimExitEvent(comLoadEventQueue[i], p->max_loads_any_thread, - "a thread reached the max load count"); + new SimLoopExitEvent(comLoadEventQueue[i], p->max_loads_any_thread, + "a thread reached the max load count"); if (p->max_loads_all_threads != 0) { // allocate & initialize shared downcounter: each event will diff --git a/src/cpu/o3/alpha_cpu_impl.hh b/src/cpu/o3/alpha_cpu_impl.hh index 446385ead..624fe8594 100644 --- a/src/cpu/o3/alpha_cpu_impl.hh +++ b/src/cpu/o3/alpha_cpu_impl.hh @@ -292,7 +292,7 @@ AlphaFullCPU::simPalCheck(int palFunc) case PAL::halt: halt(); if (--System::numSystemsRunning == 0) - new SimExitEvent("all cpus halted"); + exitSimLoop("all cpus halted"); break; case PAL::bpt: diff --git a/src/cpu/trace/opt_cpu.cc b/src/cpu/trace/opt_cpu.cc index 098031d4a..996e89f01 100644 --- a/src/cpu/trace/opt_cpu.cc +++ b/src/cpu/trace/opt_cpu.cc @@ -176,7 +176,7 @@ OptCPU::tick() fprintf(stderr,"sys.cpu.misses %d #opt cache misses\n",misses); fprintf(stderr,"sys.cpu.hits %d #opt cache hits\n", hits); fprintf(stderr,"sys.cpu.accesses %d #opt cache acceses\n", references); - new SimExitEvent("Finshed Memory Trace"); + exitSimLoop("end of memory trace reached"); } void diff --git a/src/cpu/trace/trace_cpu.cc b/src/cpu/trace/trace_cpu.cc index 4df47229f..3c9da4849 100644 --- a/src/cpu/trace/trace_cpu.cc +++ b/src/cpu/trace/trace_cpu.cc @@ -108,7 +108,7 @@ TraceCPU::tick() if (!nextReq) { // No more requests to send.
