Steve Reinhardt 0c2c7171a8 More progress... run a few instructions now, but die on the second
memory access (I think because we're deallocating our one and only
CpuRequest object).

base/loader/aout_object.cc:
base/loader/ecoff_object.cc:
base/loader/elf_object.cc:
    Add flag to force allocation of new pages on data writes.
cpu/simple/cpu.cc:
    Several minor fixes.
    Switch to atomic mode for now.
mem/physical.hh:
    Don't copy the packet to the response event, just keep a reference
    to the original.
mem/translating_port.cc:
mem/translating_port.hh:
    Add parameter to writeBlobFunctional() to force allocation of
    unallocated pages on writes.

Ron Dreslinski 31fc398f06 Fixes so that it compiles properly. Still working on .py file issues.
SConscript:
    Add Back memory to be built
mem/physical.hh:
    Fix function declerations
python/m5/objects/BaseCPU.py:
    Remove IL1 and DL1 params from the cpu object

Ron Dreslinski b6247c9ea7 Add support for multiple ports on the memory. Hook up simple cpu to memory.
Ready to start testing if I could fix the linking errors I can't ever seem to fix.

cpu/simple/cpu.cc:
cpu/simple/cpu.hh:
    Add connecting of ports until builder can handle it.
mem/physical.cc:
    Add function to allocate a port in the object

    Remove some full_sys stuff untill needed
mem/physical.hh:
    Add function to allocate a port in the object
python/m5/objects/BaseCPU.py:
    Update the params
sim/process.cc:
    Make sure to use the right name (hopefully CPU constructor already called)

Ron Dreslinski 8fc06589cb Update functional memory to have a response event
Clean out old memory python files, move them into old_mem directory.  Maybe we should just delete them, they are under revision control.

Add new py files for new objects.

SConscript:
    Update because memory is just a header file now
base/chunk_generator.hh:
    Make Chunk Generator return the entire size if the chunk_size is set to zero.  Useful when trying to chunck on blocksize of memory, which can write large pieces of data.
cpu/simple/cpu.cc:
    Make sure to delete the pkt.
mem/physical.cc:
mem/physical.hh:
    Set up response event.
mem/port.cc:
    Rename rqst to req to conform to same standard naming convention.
python/m5/objects/PhysicalMemory.py:
    Update the params, inheritence

Ron Dreslinski ceac38e41c Remove unneeded functions, moving code around abit.
mem/physical.cc:
    Remove unneeded functions.  Need to add a .toString option for commands to making printing prettier.
mem/physical.hh:
    Remove unneeded functions.

Ron Dreslinski b403abfbdb Move the port from base memory object into the physical memory object.
The Memory is now a pure virtual base class for all memory type objects (DRAM, physical).
We should consider renaming MemObject to something more meaningful to represent it is for all memory heirarchy objects, perhaps MemHeirObject?

mem/physical.cc:
mem/physical.hh:
    Move the port from the base class into the actual object.

Ron Dreslinski 1fff9f504f Some more changes for compilation. Since memset is now part of port and not virtual, no need for memory to define them.
mem/physical.cc:
    Return 0 for block size.  The chunk generator should treat this as a infinite size.
mem/physical.hh:
    Add function prototype
mem/port.hh:
    Fix function to take no arguments
mem/translating_port.cc:
mem/translating_port.hh:
    Remove the memsetBlob because it doesn't exist yet.

Ron Dreslinski 562efe214c Adding some definitons for read/write blob/string. I need to locate te code stever wrote to break up address ranges into blk/page size chunks.
cpu/simple/cpu.cc:
cpu/simple/cpu.hh:
    Add read/write blob definitions, still need to break it up into blk size chunks (where was the code stever wrote for that?)
mem/physical.hh:
    Remove un-needed function (I think)
mem/port.hh:
    Default these virtual functions to panic unimplented
mem/translating_port.cc:
    Again handling read/write string properly.

    Need the stever code to break things into page size chunks yet
mem/translating_port.hh:
    Having trouble with the const declerator.  I will need to read how it works, for now it compiles if I remove it.

Ron Dreslinski 7f114ca419 Many changes that make the new mem system compile. Now to convert the rest of the tree to use the new mem system.
mem/mem_object.hh:
    Create constrtor so it compiles
mem/packet.hh:
    Fix typedefs so they compile, add in a few more headers for compilation
mem/page_table.cc:
    convert to new mem system so it compiles
mem/page_table.hh:
    fix it to the version that had asid support.  Make it compile in the new system
mem/physical.cc:
    Fix some compilation bugs
mem/physical.hh:
    Add a type that made compile fail
mem/port.hh:
    Fix a spelling error that messed up compilation
mem/request.hh:
    fix typedefs and forward declerations so it compiles

Ron Dreslinski 4e36678028 Adding some more things toward having cpu->mem test in place. Still need to work on compilation issues.
mem/physical.cc:
mem/physical.hh:
    Added a stripped down version of the physical memory object
