a0415f2b24 ruby: use RubyMemory flag & remove setDebug() functionality
The RubyMemory flag wasnt used in the code, creating large gaps in trace output. Replace cprintfs w/dprintfs
using RubyMemory in memory controller. DPRINTF also deprecate the usage of the setDebug() pure virtual
function in the AbstractMemoryOrCache Class as well the m_debug/cprintf functions in MemoryControl.hh/cc

93a50fc318 network: set the ExtLink bw to 16 bytes
Therefore all links by default are 16 bytes wide and thus work with Garnet's
uniform link bandwidth assumption.

651cfbab03 network: adjusted default endpoint bandwidth
The simple network's endpoint bandwidth value is used to adjust the overall
bandwidth of the network.  Specifically, the ration between endpoint bandwidth
and the MESSAGE_SIZE_MULTIPLIER determines the increase.  By setting the value
to 1000, that means the bandwdith factor specified in the links translates to
the link bandwidth in bytes.  Previously, it was increasing that value by 10.

This patch will likely require a reset of the ruby regression tester stats.

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.

01fc529bb2 CacheMemory: add allocateVoid() that is == allocate() but no return value.
This function duplicates the functionality of allocate() exactly, except that it does not return
a return value.  In protocols where you just want to allocate a block
but do not want that block to be your implicitly passed cache_entry, use this function.
Otherwise, SLICC will complain if you do not consume the pointer returned by allocate(),
and if you do a dummy assignment Entry foo := cache.allocate(address), the C++
compiler will complain of an unused variable.  This is kind of a hack to get around
those issues, but suggestions welcome.

322b9ca2c5 Ruby: Add new object called WireBuffer to mimic a Wire.
This is a substitute for MessageBuffers between controllers where you don't
want messages to actually go through the Network, because requests/responses can
always get reordered wrt to one another (even if you turn off Randomization and turn on Ordered)
because you are, after all, going through a network with contention. For systems where you model
multiple controllers that are very tightly coupled and do not actually go through a network,
it is a pain to have to write a coherence protocol to account for mixed up request/response orderings
despite the fact that it's completely unrealistic.  This is *not* meant as a substitute for real
MessageBuffers when messages do in fact go over a network.

225e67f531 Ruby: pass Packet->Req->contextId() to Ruby.
It is useful for Ruby to understand from whence request packets came.
This has all request packets going into Ruby pass the contextId value, if
it exists.  This supplants the old libruby proc_id value passed around in
all the Messages, so I've also removed the unused unsigned proc_id; member
generated by SLICC for all Message types.

This class is already present in slicc_interface/RubyRequest.hh. In fact,

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.

343e94a257 Ruby: Improve Change PerfectSwitch's wakeup function
Currently the wakeup function for the PerfectSwitch contains three loops -

loop on number of virtual networks
  loop on number of incoming links
	    loop till all messages for this (link, network) have been routed

With an 8 processor mesh network and Hammer protocol, about 11-12% of the
was observed to have been spent in this function, which is the highest
amongst all the functions. It was found that the innermost loop is executed
about 45 times per invocation of the wakeup function, when each invocation
of the wakeup function processes just about one message.

The patch tries to do away with the redundant executions of the innermost
loop. Counters have been added for each virtual network that record the
number of messages that need to be routed for that virtual network. The
inner loops are only executed when the number of messages for that particular
virtual network > 0. This does away with almost 80% of the executions of the
innermost loop. The function now consumes about 5-6% of the total execution
time.

c82a8979a3 Change interface between coherence protocols and CacheMemory
The purpose of this patch is to change the way CacheMemory interfaces with
coherence protocols. Currently, whenever a cache controller (defined in the
protocol under consideration) needs to carry out any operation on a cache
block, it looks up the tag hash map and figures out whether or not the block
exists in the cache. In case it does exist, the operation is carried out
(which requires another lookup). As observed through profiling of different
protocols, multiple such lookups take place for a given cache block. It was
noted that the tag lookup takes anything from 10% to 20% of the simulation
time. In order to reduce this time, this patch is being posted.

I have to acknowledge that the many of the thoughts that went in to this
patch belong to Brad.

Changes to CacheMemory, TBETable and AbstractCacheEntry classes:
1. The lookup function belonging to CacheMemory class now returns a pointer
to a cache block entry, instead of a reference. The pointer is NULL in case
the block being looked up is not present in the cache. Similar change has
been carried out in the lookup function of the TBETable class.
2. Function for setting and getting access permission of a cache block have
been moved from CacheMemory class to AbstractCacheEntry class.
3. The allocate function in CacheMemory class now returns pointer to the
allocated cache entry.

Changes to SLICC:
1. Each action now has implicit variables - cache_entry and tbe. cache_entry,
if != NULL, must point to the cache entry for the address on which the action
is being carried out. Similarly, tbe should also point to the transaction
buffer entry of the address on which the action is being carried out.
2. If a cache entry or a transaction buffer entry is passed on as an
argument to a function, it is presumed that a pointer is being passed on.
3. The cache entry and the tbe pointers received __implicitly__ by the
actions, are passed __explicitly__ to the trigger function.
4. While performing an action, set/unset_cache_entry, set/unset_tbe are to
be used for setting / unsetting cache entry and tbe pointers respectively.
5. is_valid() and is_invalid() has been made available for testing whether
a given pointer 'is not NULL' and 'is NULL' respectively.
6. Local variables are now available, but they are assumed to be pointers
always.
7. It is now possible for an object of the derieved class to make calls to
a function defined in the interface.
8. An OOD token has been introduced in SLICC. It is same as the NULL token
used in C/C++. If you are wondering, OOD stands for Out Of Domain.
9. static_cast can now taken an optional parameter that asks for casting the
given variable to a pointer of the given type.
10. Functions can be annotated with 'return_by_pointer=yes' to return a
pointer.
11. StateMachine has two new variables, EntryType and TBEType. EntryType is
set to the type which inherits from 'AbstractCacheEntry'. There can only be
one such type in the machine. TBEType is set to the type for which 'TBE' is
used as the name.

All the protocols have been modified to conform with the new interface.

e7f2da517a ruby: Stall and wait input messages instead of recycling
This patch allows messages to be stalled in their input buffers and wait
until a corresponding address changes state.  In order to make this work,
all in_ports must be ranked in order of dependence and those in_ports that
may unblock an address, must wake up the stalled messages.  Alot of this
complexity is handled in slicc and the specification files simply
annotate the in_ports.

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

dd133c7b24 ruby: get rid of PrioHeap and use STL
One big difference is that PrioHeap puts the smallest element at the
top of the heap, whereas stl puts the largest element on top, so I
changed all comparisons so they did the right thing.

Some usage of PrioHeap was simply changed to a std::vector, using sort
at the right time, other usage had me just use the various heap functions
in the stl.

bc87fa30d7 ruby: get rid of RefCnt and Allocator stuff use base/refcnt.hh
This was somewhat tricky because the RefCnt API was somewhat odd.  The
biggest confusion was that the the RefCnt object's constructor that
took a TYPE& cloned the object.  I created an explicit virtual clone()
function for things that took advantage of this version of the
constructor.  I was conservative and used clone() when I was in doubt
of whether or not it was necessary.  I still think that there are
probably too many instances of clone(), but hopefully not too many.

I converted several instances of const MsgPtr & to a simple MsgPtr.
If the function wants to avoid the overhead of creating another
reference, then it should just use a regular pointer instead of a ref
counting ptr.

There were a couple of instances where refcounted objects were created
on the stack.  This seems pretty dangerous since if you ever
accidentally make a reference to that object with a ref counting
pointer, bad things are bound to happen.

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.

0f6535dba1 ruby: Convered ruby tracing support usage of sequencer
Modified ruby's tracing support to no longer rely on the RubySystem map
to convert a sequencer string name to a sequencer pointer.  As a
temporary solution, the code uses the sim_object find function.
Eventually, we should develop a better fix.

2c9ca672df ruby: Memory Controller Profiler with new config system
This patch includes a rather substantial change to the memory controller
profiler in order to work with the new configuration system.  Most
noteably, the mem_cntrl_profiler no longer uses a string map, but instead
a vector.  Eventually this support should be removed from the main
profiler and go into a separate object.  Each memory controller should have
a pointer to that new mem_cntrl profile object.

ed81489954 ruby: Ruby changes required to use the python config system
This patch includes the necessary changes to connect ruby objects using
the python configuration system.  Mainly it consists of removing
unnecessary ruby object pointers and connecting the necessary object
pointers using the generated param objects.  This patch includes the
slicc changes necessary to connect generated ruby objects together using
the python configuraiton system.

98c94cfe3c ruby: Convert most Ruby objects to M5 SimObjects.
The necessary companion conversion of Ruby objects generated by SLICC

alone does not compile.
Conversion of Garnet network models is also handled in a separate
patch; that code is temporarily disabled from compiling to allow
testing of interim code.

07ea0891f1 ruby: new atomics implementation
This patch changes the way that Ruby handles atomic RMW instructions. This implementation, unlike the prior one, is protocol independent. It works by locking an address from the sequencer immediately after the read portion of an RMW completes. When that address is locked, the coherence controller will only satisfy requests coming from one port (e.g., the mandatory queue) and will ignore all others. After the write portion completed, the line is unlocked. This should also work with multi-line atomics, as long as the blocks are always acquired in the same order.
