New and improved configuration mechanism. No more writing of wierd ini files. The ini files are still used as an intermediate step, but a sophisticated python library exists to help build them more easily. SConscript: add the new embedded file stuff remove all of the old object description junk base/inifile.cc: base/inifile.hh: get rid of findDefault and findAppend since they were the source of much evil. base/trace.cc: For now, if we don't have the dprintf_stream set up, dump to standard out. We probably want a command line option for this. dev/alpha_console.cc: PioDevice now takes a platform parameter. All PioDevices must have a pio_latency parameter. We stick a dummy parameter in here for now until we get rid of the builder stuff. dev/alpha_console.hh: don't need Platform anymore dev/baddev.cc: PioDevice now takes a platform parameter. All PioDevices must have a pio_latency parameter. We stick a dummy parameter in here for now until we get rid of the builder stuff. Same for the platform parameter, though we just pass the PioDevice a null parameter since it isn't used by this device and it's quicker. dev/baddev.hh: fix #include guards dev/etherlink.cc: rename parameters. dev/ethertap.cc: rename parameters dev/ide_ctrl.cc: All devices need an address even if it will get overwritten later. dev/ide_disk.cc: use an enum for the drive ID stuff. rename disk_delay -> delay Actually, I think that we should implement "cable select" and have the controller tell the drive what it is. dev/io_device.cc: dev/io_device.hh: All IO devices take a Platform * dev/ns_gige.cc: all devices need an io_bus. rename header_bus to io_bus We don't need stuff for the interrupt controller since it's all in the platform now. dev/ns_gige.hh: We don't need stuff for the interrupt controller now since it's all in the platform. dev/pciconfigall.cc: Pass a dummy NULL to the PioDevice for the platform since we don't need one. dev/pcidev.cc: Move a bunch of common functionality into the PciDev dev/platform.hh: remove unneeded code dev/tsunami.cc: remove unused param dev/tsunami_cchip.cc: pass platform pointer dev/tsunami_io.cc: dev/tsunami_pchip.cc: dev/uart.cc: pass platform variable dev/uart.hh: don't need to keep a platform pointer. it's in the base class kern/linux/linux_system.cc: kern/tru64/tru64_system.cc: rename some parameters sim/builder.cc: clean up builder code. use more parameters from the config node. all sections with a type= are now created, the old mechanisms no longer work sim/builder.hh: remove some extra variables since they are found in the ConfigNode sim/main.cc: add a quick hack command line argument -X to dump out the embedded files.

Move SimObject creation and Port connection loops into Python. Add Port and VectorPort objects and support for specifying port connections via assignment.

Add support for declaring and connecting MemObject ports in Python. src/python/m5/objects/Bus.py: src/python/m5/objects/PhysicalMemory.py: Add port declaration. src/sim/builder.cc: src/sim/builder.hh: src/sim/serialize.cc: src/sim/serialize.hh: ConfigNodes are gone; builder just gets the name of a .ini file section now. src/sim/main.cc: Move SimObject construction and port connection operations into Python (with C++ calls). Split remaining initialization operations into two parts, loadIniFile() and finalInit(). src/sim/param.cc: src/sim/param.hh: SimObject resolution done globally in Python now (not via ConfigNode hierarchy). src/sim/sim_object.cc: Remove unneeded #include. --HG-- extra : convert_revision : 2fa4001eaaec0c9a4231ef6e854f8e156d930dfe

Split SimpleCPU into two different models, AtomicSimpleCPU and TimingSimpleCPU, which use atomic and timing memory accesses respectively. Common code is factored into the BaseSimpleCPU class. AtomicSimpleCPU includes an option (simulate_stalls) to add delays based on the estimated latency reported by the atomic accesses. Plain old "SimpleCPU" is gone; I have not updated all the config files (just test/test.py). Also fixes to get timing accesses working in new memory model and to get split-phase memory instruction definitions working with new memory model as well. arch/alpha/isa/main.isa: Need to include packet_impl.h for functions that use Packet objects. arch/alpha/isa/mem.isa: Change completeAcc() methods to take Packet object pointers. Also split out StoreCond template for completeAcc(), since that's the only one that needs write_result and we get an unused variable warning if we always have it in there. build/SConstruct: Update list of recognized CPU model names. configs/test/test.py: Change SimpleCPU to AtomicSimpleCPU. cpu/SConscript: Define sources for new CPU models. Add split memory access methods to CPU model signatures. cpu/cpu_models.py: cpu/static_inst.hh: Define new CPU models. cpu/simple/base.cc: cpu/simple/base.hh: Factor out pieces specific to Atomic or Timing models. mem/bus.cc: Bus needs to be able to route timing packets based on explicit dest so responses can get back to requester. Set dest to Packet::Broadcast to indicate that dest should be derived from address. Also set packet src field based on port from which packet is sent. mem/bus.hh: Set packet src field based on port from which packet is sent. mem/packet.hh: Define Broadcast destination address to indicate that packet should be routed based on address. mem/physical.cc: Set packet dest on response so packet is routed back to requester properly. mem/port.cc: Flag blob packets as Broadcast. python/m5/objects/PhysicalMemory.py: Change default latency to be 1 cycle. --HG-- rename : cpu/simple/cpu.cc => cpu/simple/base.cc rename : cpu/simple/cpu.hh => cpu/simple/base.hh extra : convert_revision : e9646af6406a20c8c605087936dc4683375c2132
