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.

    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

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.

40bab977bc Better handling of latency/frequency parameter types
python/m5/config.py:
    Addr is slightly different from memory size in that Addr
    will take non strings.
    Deal with the fact that the convert.toFoo functions only accept
    strings.
    Add RootFrequency as a special type for the Root.frequency
    parameter which is not scaled.
    Add ClockPeriod parameter type.
python/m5/convert.py:
    Be more strict about what's allowed.
    Only accept strings as inputs for these conversion functions.
    If the user wants to accept something else, they need to deal
    with the failure and convert other types on their own.
python/m5/objects/Bus.mpy:
    Use the new ClockPeriod parameter type
python/m5/objects/Root.mpy:
    Can't use integers for frequency anymore
python/m5/smartdict.py:
    rename SmartDict.Proxy to just Variable.  Create a new class
    UndefinedVariable that is returned when the user tries to get
    a variable that is not in the dict.  Undefined variable evaluates
    to false, and will cause an error elsewhere.

eeff53841a Add Frequency and Latency as new parameter types and use them
where we can

python/m5/config.py:
    Add two new parameter types: Frequency and Latency.  These will soon
    be an integral part of the tick is picosecond thing.  If the value
    can be converted directly to an integer without any special tricks,
    we assume that the number is the exact value desired.  Otherwise,
    we convert the number assuming that it is in Hz or s.
python/m5/objects/Bus.mpy:
    Use the new Latency and Frequency types where we can

153130e558 First step in fixing up parameter handling. Clean up the
way ranges work, more fully support metric prefixes for all
integer types, and convert memory sized parameters to the
MemorySize type.

python/m5/config.py:
    - no more _Param and _ParamProxy stuff.  Use the names
    ParamBase and ParamFactory to hopefully make it clearer
    what we intend.
    - Get rid of RangeSize and the old Range class and more fully flesh
    out the Range class to deal with types of parameters and different
    kinds of ranges.
    - Call toInteger on the CheckedInt types so we can use metric prefixes
    in strings for all integers.
    - Get rid of the K, M, and G constants.  Use the proper type or call
    one of the functions in the convert package.
python/m5/convert.py:
    Simple way to deal with both floating point and integer strings.
python/m5/objects/BaseCache.mpy:
python/m5/objects/Ethernet.mpy:
    This is a MemorySize typed parameter

    that derive from param type so that non-type classes work
    too.  (Those that are just derived from ConfigNode and not
    SimObject.)

3583fb6830 Use the multidict in the python config stuff. Makes code a bit
cleaner.

python/m5/config.py:
    Use the multidict instead of the separately coded _getparam
    and _getvalue stuff.  While we're at it, when we see a default
    parameter, we stick it into the dictionary right away.

c929ee2c10 Byproducts of aborted attempt to refine 'parent' proxy semantics.
Mostly cleanup of mpy_importer.mpy_parse().

python/m5/__init__.py:
    Move panic() up to top in case we want to use it
    in mpy_importer (though I ended up not doing that
    after all).
python/m5/config.py:
    Add a couple of comments and a check for expressions
    like parent.any.foo (which is illegal).

0903013669 Allow proxies to refer to proxies in config files.

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.

    Include simobj/SConscript

    Fix type in comment
python/SConscript:
    Move CPPDEFINES dict-generating code to m5scons.flatten_defines

    just here as proof of concept.

8dff74b26f Clean up import situation... key things are:
- global tracking of legitimate param types in
separate dict keeps us from having to import
objects in config.py, which gets rid of nasty
circular dependence
- use __all__ in config.py and restrict imports
from mpy_importer to reduce m5 namespace pollution

python/m5/__init__.py:
    Try to limit namespace pollution by only importing
    what's needed from mpy_importer.
    Explicitly set up legal parameter types rather than
    relying on eval().
python/m5/config.py:
    Use empty ParamType base class to distinguish
    types that are legitimate SimObject params.
    Explicitly add these to global param_types map.
    Rework CheckedInt and Range classes a little bit
    to fit in better with the model.
    No need to import objects here any longer.
    Add __all__ list to specify subset of names that
    get exported on 'from m5.config import *'.
