Virtualize sinic
- The io registers are replicated many times in memory, allowing the NIC to
differentiate among several virtual interfaces.
- On the TX side, this allows multiple CPUs to initiate transmits at the same
time without locking in the software. If a partial packet is transmitted,
then the state machine blocks waiting for that virtual interface to complete
its packet. Then the state machine will move on to the next virtual
interface. The commands are kept in fifo order.
- On the RX side, multiple partial transmits can be simultaneously done.
Though a packet does not deallocate its fifo space until all preceeding
packets in the fifo are deallocated. To enable multiple receives, it
is necessary for each virtual nic to keep its own information about its
progress through the state machine.

Receive state must be virtualized since we allow the receipt of packets in

- read all registers directly from the register space by offset

to device registers through an ipr or special instruction.
- When RxData or TxData are written, their busy flag is set to
indicate that they have an outstanding transaction.
- The RxHigh and TxLow interrupts are special, they only interrupt

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.

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.

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/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'.

.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

sim/sim_object.hh:
Include auto-generated Param struct. Not used yet,
just here as proof of concept.
