0788ea7b3b hammer: fixed dma uniproc error
Fixed an error reguarding DMA for uninprocessor systems.  Basically removed an
overly agressive optimization that lead to inconsistent state between the
cache and the directory.

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.

d857105b5a Ruby: Simplify SLICC and Entry/TBE handling.
Before this changeset, all local variables of type Entry and TBE were considered
to be pointers, but an immediate use of said variables would not be automatically
deferenced in SLICC-generated code.  Instead, deferences occurred when such
variables were passed to functions, and were automatically dereferenced in
the bodies of the functions (e.g. the implicitly passed cache_entry).

This is a more general way to do it, which leaves in place the
assumption that parameters to functions and local variables of type AbstractCacheEntry
and TBE are always pointers, but instead of dereferencing to access member variables
on a contextual basis, the dereferencing automatically occurs on a type basis at the
moment a member is being accessed.  So, now, things you can do that you couldn't before
include:

Entry foo := getCacheEntry(address);
cache_entry.DataBlk := foo.DataBlk;

or

cache_entry.DataBlk := getCacheEntry(address).DataBlk;

or even

cache_entry.DataBlk := static_cast(Entry, pointer, cache.lookup(address)).DataBlk;

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.

e0fdd86fd9 mips: cleanup ISA-specific code
***
(1): get rid of expandForMT function
MIPS is the only ISA that cares about having a piece of ISA state integrate
multiple threads so add constants for MIPS and relieve the other ISAs from having
to define this. Also, InOrder was the only core that was actively calling
this function
* * *
(2): get rid of corespecific type
The CoreSpecific type was used as a proxy to pass in HW specific params to
a MIPS CPU, but since MIPS FS hasnt been touched for awhile, it makes sense
to not force every other ISA to use CoreSpecific as well use a special
reset function to set it. That probably should go in a PowerOn reset fault
 anyway.

1764ebbf30 Ruby: Remove CacheMsg class from SLICC
The goal of the patch is to do away with the CacheMsg class currently in use
in coherence protocols. In place of CacheMsg, the RubyRequest class will used.
This class is already present in slicc_interface/RubyRequest.hh. In fact,
objects of class CacheMsg are generated by copying values from a RubyRequest
object.

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.

18142df5b9 SLICC: Remove external_type for structures
In SLICC, in order to define a type a data type for which it should not
generate any code, the keyword external_type is used. For those data types for
which code should be generated, the keyword structure is used. This patch
eliminates the use of keyword external_type for defining structures. structure
key word can now have an optional attribute external, which would be used for
figuring out whether or not to generate the code for this structure. Also, now
structures can have functions as well data members in them.

cc14689a86 swig: get rid of m5.internal.random module (swig/random.i)
Thanks to swig this was interfering with the standard Python

which erroneously called srand48().  Moved the function to
m5.internal.core, renamed it seedRandom(), and made it call
random_mt.init() instead.

031f396c71 ARM: Fix RFE macrop.
This changes the RFE macroop into 3 microops:

URa = [sp]; URb = [sp+4]; // load CPSR,PC values from stack
sp = sp + offset;         // optionally auto-increment
PC = URa; CPSR = URb;     // write to the PC and CPSR.

Importantly:
- writing to PC is handled in the last micro-op.
- loading occurs prior to state changes.

a432d8e085 Mem: Fix issue with dirty block being lost when entire block transferred to non-cache.
This change fixes the problem for all the cases we actively use. If you want to try
more creative I/O device attachments (E.g. sharing an L2), this won't work. You
would need another level of caching between the I/O device and the cache
(which you actually need anyway with our current code to make sure writes
propagate). This is required so that you can mark the cache in between as
top level and it won't try to send ownership of a block to the I/O device.
Asserts have been added that should catch any issues.

2f40b3b8ae O3: Fix unaligned stores when cache blocked
Without this change the a store can be issued to the cache multiple times.
If this case occurs when the l1 cache is out of mshrs (and thus blocked)
the processor will never make forward progress because each cycle it will
send a single request using the recently freed mshr and not completing the
multipart store. This will continue forever.

8966312785 X86: Decode the mysterious and elusive ffreep x87 instruction.
The internet says this instruction was created by accident when an Intel CPU
failed to decode x87 instructions properly. It's been documented on a few rare
occasions and has generally worked to ensure backwards compatability. One
source claims that the gcc toolchain is basically the only thing that emits
it, and that emulators/binary translators like qemu and bochs implement it.

We won't actually implement it here since we're hardly implementing any other
x87 instructions either. If we were to implement it, it would behave the same
as ffree but then also pop the register stack.

68bd80794c O3: Fix bug when a squash occurs right before TLB miss returns.

e572cf93ee ARM: Delete OABI syscall handling.
We only support EABI binaries, so there is no reason to support OABI syscalls.
The loader detects OABI calls and fatal() so there is no reason to even check
here.

2157b9976b ARM: Reset simulation statistics when pref counters are reset.
The ARM performance counters are not currently supported by the model.
This patch interprets a 'reset performance counters' command to mean 'reset
the simulator statistics' instead.

78c37b8048 ruby: extend dprintfs for RubyGenerated TraceFlag
"executing" isnt a very descriptive debug message and in going through the
output you get multiple messages that say "executing" but nothing to help
you parse through the code/execution.

So instead, at least print out the name of the action that is taking
place in these functions.
