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:

dev/tsunami_io.cc:

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:

All PioDevices must have a pio_latency parameter. We stick

sim/pyconfig/m5config.py:
Major changes to the original configuration file generator. These
changes largely involve implementing copy-on-write like semantics
