2007-07-23Major changes to how SimObjects are created and initialized. Almost allNathan Binkert
creation and initialization now happens in python. Parameter objects are generated and initialized by python. The .ini file is now solely for debugging purposes and is not used in construction of the objects in any way. --HG-- extra : convert_revision : 7e722873e417cb3d696f2e34c35ff488b7bff4ed

is probably fine as far as the predecoder goes, but the simple cpu might want to not refetch something it already has. That reintroduces the self modifying code problem though. --HG-- extra : convert_revision : 802197e65f8dc1ad657c6b346091e03cb563b0c0

2007-03-10Rework the way SCons recurses into subdirectories, making itNathan Binkert
automatic. The point is that now a subdirectory can be added to the build process just by creating a SConscript file in it. The process has two passes. On the first pass, all subdirs of the root of the tree are searched for SConsopts files. These files contain any command line options that ought to be added for a particular subdirectory. On the second pass, all subdirs of the src directory are searched for SConscript files. These files describe how to build any given subdirectory. I have added a Source() function. Any file (relative to the directory in which the SConscript resides) passed to that function is added to the build. Clean up everything to take advantage of Source(). function is added to the list of files to be built. --HG-- extra : convert_revision : 103f6b490d2eb224436688c89cdc015211c4fd30

2007-03-09Two fixes:Kevin Lim
1. Make sure connectMemPorts() only gets called when the CPU's peer gets changed. This is done by making setPeer() virtual, and overriding it in the CPU's ports. When it gets called on a CPU's port (dcache specifically), it calls the normal setPeer() function, and also connectMemPorts(). 2. Consolidate redundant code that handles switching in a CPU. src/cpu/base.cc: Move common code of switching over peers to base CPU. src/cpu/base.hh: Move common code of switching over peers to BaseCPU. src/cpu/o3/cpu.cc: Add in function that updates thread context's ports. Also use updated function to takeOverFrom() in BaseCPU. This gets rid of some repeated code. src/cpu/o3/cpu.hh: Include function to update thread context's memory ports. src/cpu/o3/lsq.hh: Add function to dcache port that will update the memory ports upon getting a new peer. Also include a function that will tell the CPU to update those memory ports. src/cpu/o3/lsq_impl.hh: Add function that will update the memory ports upon getting a new peer. src/cpu/simple/atomic.cc: src/cpu/simple/timing.cc: Add function that will update thread context's memory ports upon getting a new peer. Also use the new BaseCPU's take over from function. src/cpu/simple/atomic.hh: Add in function (and dcache port) that will allow the dcache to update memory ports when it gets assigned a new peer. src/cpu/simple/timing.hh: Add function that will update thread context's memory ports upon getting a new peer. src/mem/port.hh: Make setPeer virtual so that other classes can override it. --HG-- extra : convert_revision : 2050f1241dd2e83875d281cfc5ad5c6c8705fdaf
