ac993964a9 GARNET: adding a fault model for resilient on-chip network research.
This patch adds a fault model, which provides the probability of a number of
architectural faults in the interconnection network (e.g., data corruption,
misrouting). These probabilities can be used to realistically inject faults
in GARNET and faithfully evaluate the effectiveness of novel resilient NoC
architectures.

00ad4eb8ce Ruby: Fix instantiations of DMA controller and sequencer
The patch on Ruby functional accesses made changes to the process of
instantiating controllers and sequencers. The DMA controller and
sequencer was not updated, hence this patch.

5e0851d554 Network_test: Conform it with functional access changes in Ruby
Addition of functional access support to Ruby necessitated some changes to
the way coherence protocols are written. I had forgotten to update the
Network_test protocol. This patch makes those updates.

c86f849d5a Ruby: Add support for functional accesses
This patch rpovides functional access support in Ruby. Currently only
the M5Port of RubyPort supports functional accesses. The support for
functional through the PioPort will be added as a separate patch.

8a652f9871 config: tweak ruby configs to clean up hierarchy
Re-enabling implicit parenting (see previous patch) causes current
Ruby config scripts to create some strange hierarchies and generate
several warnings.  This patch makes three general changes to address
these issues.

1. The order of object creation in the ruby config files makes the L1
   caches children of the sequencer rather than the controller; these
   config ciles are rewritten to assign the L1 caches to the
   controller first.

2. The assignment of the sequencer list to system.ruby.cpu_ruby_ports
   causes the sequencers to be children of system.ruby, generating
   warnings because they are already parented to their respective
   controllers.  Changing this attribute to _cpu_ruby_ports fixes this
   because the leading underscore means this is now treated as a plain
   Python attribute rather than a child assignment. As a result, the
   configuration hierarchy changes such that, e.g.,
   system.ruby.cpu_ruby_ports0 becomes system.l1_cntrl0.sequencer.

3. In the topology classes, the routers become children of some random
   internal link node rather than direct children of the topology.
   The topology classes are rewritten to assign the routers to the
   topology object first.

8733ed4b7d network: basic link bw for garnet and simple networks
This patch ensures that both Garnet and the simple networks use the bw value
specified in the topology.  To do so, the patch generalizes the specification
of bw for basic links.  This value is then translated to the specific value
used by the simple and Garnet networks.  Since Garent does not support
non-uniformed link bandwidth, the patch also adds a check to ensure all bws are
equal.

40bcbf4253 network: convert links & switches to first class C++ SimObjects
This patch converts links and switches from second class simobjects that were
virtually ignored by the networks (both simple and Garnet) to first class
simobjects that directly correspond to c++ ojbects manipulated by the
topology and network classes.  This is especially true for Garnet, where the
links and switches directly correspond to specific C++ objects.

By making this change, many aspects of the Topology class were simplified.

09c3a97a4c This patch adds the network tester for simple and garnet networks.
The tester code is in testers/networktest.
The tester can be invoked by configs/example/ruby_network_test.py.
A dummy coherence protocol called Network_test is also addded for network-only simulations and testing. The protocol takes in messages from the tester and just pushes them into the network in the appropriate vnet, without storing any state.

af6b97e3ee ruby: Recycle latency fix for hammer
Patch allows each individual message buffer to have different recycle latencies

72044e3f5a ruby: Disable migratory sharing for token and hammer
This patch allows one to disable migratory sharing for those cache blocks that
are accessed by atomic requests.  While the implementations are different
between the token and hammer protocols, the motivation is the same.  For
Alpha, LLSC semantics expect that normal loads do not unlock cache blocks that
have been locked by LL accesses.  Therefore, locked blocks should not transfer
write permissions when responding to these load requests.  Instead, only they
only transfer read permissions so that the subsequent SC access can possibly
succeed.

29c45ccd23 ruby: Reduced ruby latencies
The previous slower ruby latencies created a mismatch between the faster M5
cpu models and the much slower ruby memory system.  Specifically smp
interrupts were much slower and infrequent, as well as cpus moving in and out
of spin locks.  The result was many cpus were idle for large periods of time.

These changes fix the latency mismatch.

f88faa6c11 ruby: cleaned up ruby profilers
Cleaned up the ruby profilers by moving the memory controller profiling code
out of the main profiler object and into a separate object similar to the
current CacheProfiler.  Both the CacheProfiler and MemCntrlProfiler are
specific to a particular Ruby object, CacheMemory and MemoryControl
respectively.  Therefore, these profilers should not be SimObjects and
created by the python configuration system, but instead private objects.  This
simplifies the creation of these profilers.
