AtomicSimpleCPU with a cache now runs the hello world! test program.
Need to clean up a bunch of flags/hacks in the code. Then onto Timming mode. Functional accesses also work properly, although not exactly how we wanted them. I'll need to clean that up as well. src/cpu/simple/atomic.cc: Atomic CPU needs to set thread context so stats work in cache. Temporarily just use CPU=0 ThreadID=0 src/mem/cache/cache_impl.hh: Need to return success/failure properly still Physical memory object doesn't assert SATISFIED anymore, need to remove that flag src/mem/cache/tags/lru.cc: Doesn't work if the REQ doesn't set it's ASID. Temporary fix use 0 always --HG-- extra : convert_revision : d06a39684af593db699b64df9a29f80c61d8d050
