Ali Saidi 92c5a5c8cb More changes to get SPARC fs closer. Now at 1.2M cycles before difference
configs/common/FSConfig.py:
    seperate the hypervisor memory and the guest0 memory. In reality we're going to need a better way to do this at some point. Perhaps auto generating the hv-desc image based on the specified config.
src/arch/sparc/isa/decoder.isa:
    change reads/writes to the [hs]tick(cmpr) registers to use readmiscregwitheffect
src/arch/sparc/miscregfile.cc:
    For niagra stick and tick are aliased to one value (if we end up doing mps we might not want this).
    Use instruction count from cpu rather than cycles because that is what legion does
    we can change it back after were done with legion
src/base/bitfield.hh:
    add a new function mbits() that just masks off bits of interest but doesn't shift
src/cpu/base.cc:
src/cpu/base.hh:
    add instruction count to cpu
src/cpu/exetrace.cc:
src/cpu/m5legion_interface.h:
    compare instruction count between legion and m5 too
src/cpu/simple/atomic.cc:
    change asserts of packet success to if panics wrapped with NDEBUG defines
    so we can get some more useful information when we have a bad address
src/dev/isa_fake.cc:
src/dev/isa_fake.hh:
src/python/m5/objects/Device.py:
    expand isa fake a bit more having data for each size request, the ability to have writes update the data and to warn on accesses
src/python/m5/objects/System.py:
    convert some tabs to spaces
src/python/m5/objects/T1000.py:
    add more fake devices for each l1 bank and each memory controller

Kevin Lim c96160cef5 Change the connecting of the physPort and virtPort to the memory object below the CPU to happen every time activateContext is called. The overhead is probably a little higher than necessary, but allows these connections to properly be made when there are CPUs that are inactive until they are switched in.
Right now this introduces a minor memory leak as old physPorts and virtPorts are not deleted when new ones are created.  A flyspray task has been created for this issue.  It can not be resolved until we determine how the bus will handle giving out ID's to functional ports that may be deleted.

src/cpu/o3/cpu.cc:
src/cpu/simple/atomic.cc:
src/cpu/simple/timing.cc:
    Change the setup of the physPort and virtPort to instead happen every time the CPU has a context activated.  This is a little high overhead, but keeps it working correctly when the CPU does not have a physical memory attached to it until it switches in (like the case of switch CPUs).
src/cpu/o3/thread_context.hh:
    Change function from being called at init() to just being called whenever the memory ports need to be connected.
src/cpu/o3/thread_context_impl.hh:
    Update this to not delete the port if it's the same as the virtPort.
src/cpu/thread_context.hh:
    Change function from being called at init() to whenever the memory ports need to be connected.
src/cpu/thread_state.cc:
    Instead of initializing the ports, simply connect them, deleting any old ports that might exist.  This allows these functions to be called multiple times.
src/cpu/thread_state.hh:
    Ports are no longer initialized, but rather connected at context activation time.

Kevin Lim 069c7c30d1 Various fixes to delete packet and request a little better.
src/cpu/simple/timing.cc:
    Various updates for deleting requests more properly.

    The major change is moving the deletion of the fetch request/packet to after the instruction has executed and completed.  This should fix a few bugs because Ron's memory system didn't expect a call for a functional access while a timing access was being processed.

Ron Dreslinski 903a618714 Fix a bug to handle the fact that a CPU can send Functional accesses while a sendTiming has not returned in the call stack.
src/mem/cache/base_cache.cc:
    Sometimes a functional access comes while waiting on a outstanding packet being sent.
    This could be because Timing CPU does some post processing on the recvTiming which send functional access.
    Either the CPU should leave the pkt/req around (so They can be referenced in the mem system). Or the mem
    system should remove them from outstanding lists and reinsert them if they fail in the sendTiming.

    I did the later, eventually we should consider doing the former if that is the correct behavior.
