Two fixes:
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
