2006-07-23This changeset gets the MIPS ISA pretty much working in the O3CPU. It ↵Korey Sewell
builds, runs, and gets very very close to completing the hello world succesfully but there are some minor quirks to iron out. Who would've known a DELAY SLOT introduces that much complexity?! arrgh!

SConstruct: Include an option to specify the CPUs being tested. src/cpu/SConscript: Checker isn't SMT right now, so don't do SMT tests with the O3CPU if we're using the checker. src/python/m5/objects/O3CPU.py: Include default options. Unfortunately FullO3Config.py is still needed because it specifies which FUPool is being used. tests/SConscript: Several minor updates (sorry for one commit).

2006-07-19Put regression tests back into m5. They are located in the "tests" ↵Kevin Lim
directory. The directory output and reference outputs have changed slightly. Now the directory is ALPHA_SE/test/<test>/<cpu_model>/, and for the reference stats <test>/ref/<arch>/<cpu_model> Right now only non-SMT SE regression tests have been added back in. The rest are pending getting SMT working, and consolidating the FS configuration files. Eventually support for different OSs can be added so you can specify which versions of the binary you want to run from one config file. Note: mp-test1 doesn't have any reference stats because MP mode doesn't currently work. The test itself should probably work once the code is fixed. SConstruct: Updates to allow for regression tests to work via the command line "scons build/ALPHA_SE/test/debug/quick" and such once again. src/cpu/SConscript: Keep a list of SMT supporting CPUs so that the regression tests can easily specify which CPUs to use if they are SMT only. --HG-- extra : convert_revision : 34e6286150aae8f316ae694f6c00be8f510522f2

2006-07-06Timing cache works for hello world test.Ron Dreslinski
Still need 1) detailed CPU (blocking ability in cache) 1a) Multiple outstanding requests (need to keep track of times for events) 2)Multi-level support 3)MP coherece support 4)LL/SC support 5)Functional path needs to be correctly implemented (temporarily works without multiple outstanding requests (simple cpu)) src/cpu/simple/timing.cc: Temp hack because timing cpu doesn't export ports properly so single I/D cache communicates only through the Icache port. src/mem/cache/base_cache.cc: Handle marking MSHR's in service Add support for getting CSHR's src/mem/cache/base_cache.hh: Make these functions visible at the base cache level src/mem/cache/cache.hh: make the functions virtual src/mem/cache/cache_impl.hh: Rename the function to make sense src/mem/packet.hh: Accidentally clearing the needsResponse field when sending a response back. --HG-- extra : convert_revision : 2325d4e0b77e470fa9da91490317dc8ed88b17e2
2006-07-06Fixes for draining.Kevin Lim
src/cpu/simple/timing.cc: Update for changed return values. src/python/m5/__init__.py: Loop in order to make sure all objects are really drained. Objects may become undrained as other objects become drained (e.g. a bus-bridge has a packet, while a bus is empty, and the first drain() will cause the bus-bridge to give the packet to the bus). The only case we know every object is actually drained is if they all return immediately that they are drained. --HG-- extra : convert_revision : 80057a1d6d30381bd0b67b23549bd202f447c5cb
