5eab6c4b41 Make the notion of a global event tick independent of the actual
CPU cycle ticks.  This allows the user to have CPUs of different
frequencies, and also allows frequencies and latencies that are
not evenly divisible by the CPU frequency.  For now, the CPU
frequency is still set to the global frequency, but soon, we'll
hopefully make the global frequency fixed at something like 1THz
and set all other frequencies independently.

arch/alpha/ev5.cc:
    The cycles counter is based on the current cpu cycle.
cpu/base_cpu.cc:
    frequency isn't the cpu parameter anymore, cycleTime is.
cpu/base_cpu.hh:
    frequency isn't the cpu parameter anymore, cycleTime is.
    create several public functions for getting the cpu frequency
    and the numbers of ticks for a given number of cycles, etc.
cpu/memtest/memtest.cc:
cpu/simple_cpu/simple_cpu.cc:
cpu/simple_cpu/simple_cpu.hh:
cpu/trace/trace_cpu.cc:
    Now that ticks aren't cpu cycles, fixup code to advance
    by the proper number of ticks.
cpu/memtest/memtest.hh:
cpu/trace/trace_cpu.hh:
    Provide a function to get the number of ticks for a given
    number of cycles.
dev/alpha_console.cc:
    Update for changes in the way that frequencies and latencies are
    accessed.  Move some stuff to init()
dev/alpha_console.hh:
    Need a pointer to the system and the cpu to get the frequency
    so we can pass the info to the console code.

dev/etherlink.hh:
dev/ethertap.cc:
dev/ide_disk.hh:
dev/ns_gige.cc:
dev/ns_gige.hh:
    update for changes in the way bandwidths are passed from
    python to C++ to accomidate the new way that ticks works.
dev/ide_disk.cc:
    update for changes in the way bandwidths are passed from
    python to C++ to accomidate the new way that ticks works.
    Add some extra debugging printfs
dev/platform.cc:
dev/sinic.cc:
dev/sinic.hh:
    outline the constructor and destructor
dev/platform.hh:
    outline the constructor and destructor.
    don't keep track of the interrupt frequency.  Only provide the
    accessor function.
dev/tsunami.cc:
dev/tsunami.hh:
    outline the constructor and destructor
    Don't set the interrupt frequency here.  Get it from the actual device
    that does the interrupting.
dev/tsunami_io.cc:
dev/tsunami_io.hh:
    Make the interrupt interval a configuration parameter.  (And convert
    the interval to the new latency/frequency stuff in the python)
kern/linux/linux_system.cc:
    update for changes in the way bandwidths are passed from
    python to C++ to accomidate the new way that ticks works.
    For now, we must get the boot cpu's frequency as a parameter
    since allowing the system to have a pointer to the boot cpu would
    cause a cycle.
kern/tru64/tru64_system.cc:
    For now, we must get the boot cpu's frequency as a parameter
    since allowing the system to have a pointer to the boot cpu would
    cause a cycle.
python/m5/config.py:
    Fix support for cycle_time relative latencies and frequencies.
    Add support for getting a NetworkBandwidth or a MemoryBandwidth.
python/m5/objects/BaseCPU.mpy:
    All CPUs now have a cycle_time.  The default is the global frequency,
    but it is now possible to set the global frequency to some large value
    (like 1THz) and set each CPU frequency independently.
python/m5/objects/BaseCache.mpy:
python/m5/objects/Ide.mpy:
    Make this a Latency parameter
python/m5/objects/BaseSystem.mpy:
    We need to pass the boot CPU's frequency to the system
python/m5/objects/Ethernet.mpy:
    Update parameter types to use latency and bandwidth types
python/m5/objects/Platform.mpy:
    this frequency isn't needed.  We get it from the clock interrupt.
python/m5/objects/Tsunami.mpy:
    The clock generator should hold the frequency
sim/eventq.hh:
    Need to remove this assertion because the writeback event
    queue is different from the CPU's event queue which can cause
    this assertion to fail.
sim/process.cc:
    Fix comment.
sim/system.hh:
    Struct member to hold the boot CPU's frequency.
sim/universe.cc:
    remove unneeded variable.

c8538d6a7e Enhancements to python config proxy class.
python/m5/config.py:
    - Enhanced Proxy class now supports subscripting, e.g.,
    parent.cpu[0] or even parent.cpu[0].icache.

    - Proxy also supports multiplication (e.g., parent.cycle * 3),
    though this feature has not been tested.

    - Subscript 0 works even on non-lists, so you can safely say
    cpu[0] and get the first cpu even if there's only one.

    - Changed name of proxy object from 'Super' to 'parent', and
    changed "wild card" notation from plain 'Super' to 'parent.any'.

1b841a871e - Add capability to auto-generate Param structs from
.mpy SimObject descriptions.  Structs are defined
in simobj/param/ObjectName.hh.
- Move compile-time python params (from CPPDEFINES) to
separate dict from run-time params (from os.environ).
The former are needed to generate proper param structs.
This also helps prevent users from messing things up
by setting the wrong environment vars (which could have
overridden compile-time settings in the old system).
- Other misc cleanup of m5 python package.

SConscript:
    Include simobj/SConscript
build/SConstruct:
    Fix type in comment
python/SConscript:
    Move CPPDEFINES dict-generating code to m5scons.flatten_defines
python/m5/__init__.py:
    - Generate a build_env SmartDict here to hold compile-time
    params (passed in via __main__.m5_build_env).
    - Move panic and env here from config.py.
python/m5/config.py:
    Move panic, env to top level (m5/__init__.py)
python/m5/objects/BaseCPU.mpy:
    Use build_env instead of env for compile-time params
python/m5/smartdict.py:
    Add some comments.
sim/sim_object.hh:
    Include auto-generated Param struct.  Not used yet,
    just here as proof of concept.
test/genini.py:
    Put -E arguments in build_env as well as os.environ

c393a51f4a move the conversion stuff that was in configs/kernel/Config.py into
the m5 package as convert.py
add a smartdict class which stores strings and can intelligently
interpret those string variables as several other types.
make the env dict use the smartdict class

python/m5/config.py:
    move a bunch of conversion functions into convert.py
    turn the env dict into a smartdict
    adapt the _CheckedInt stuff to deal with derived types
python/m5/objects/BaseCPU.mpy:
    env is now a smartdict and can properly convert to bool

cf05fa476d stick all python stuff into a top level python directory.
create an m5 package in python/m5
move the objects package into the m5 package
move the m5config into the m5 package as config
leave both importers outside of the package.

SConscript:
sim/main.cc:
    move sim/pyconfig/* -> python
python/SConscript:
    m5config.py -> m5/config.py (now automatically embedded)
    objects -> python/m5/objects
    embed all python files in python/m5
python/m5/config.py:
    importer renamed mpy_importer
    move code to m5/__init__.py
test/genini.py:
    deal with new python organization
    keep track of paths we want to add and add them after parameters
    are parsed.
