74553c7d3f stats: Update the stats to reflect bus and memory changes
This patch updates the stats to reflect the addition of the bus stats,
and changes to the bus layers. In addition it updates the stats to
match the addition of the static pipeline latency of the memory
conotroller and the addition of a stat tracking the bytes per
activate.

3bc4ecdcb4 mem: More descriptive DRAM config names
This patch changes the class names of the variuos DRAM configurations
to better reflect what memory they are based on. The speed and
interface width is now part of the name, and also the alias that is
used to select them on the command line.

Some minor changes are done to the actual parameters, to better
reflect the named configurations. As a result of these changes the
regressions change slightly and the stats will be bumped in a separate
patch.

3477d60d5c config: Add a mem-type config option to se/fs scripts
This patch enables selection of the memory controller class through a
mem-type command-line option. Behind the scenes, this option is
treated much like the cpu-type, and a similar framework is used to
resolve the valid options, and translate the short-hand description to
a valid class.

The regression scripts are updated with a hardcoded memory class for
the moment. The best solution going forward is probably to get the
memory out of the makeSystem functions, but Ruby complicates things as
it does not connect the memory controller to the membus.

dc83d23425 tests: Add support for testing KVM-based CPUs
This changeset adds support for initializing a KVM VM in the
BaseSystem test class and adds the following methods in run.py:

require_file -- Test if a file exists and abort/skip if not.
require_kvm -- Test if KVM support has been compiled into gem5 (i.e.,
	       BaseKvmCPU exists) and the KVM device exists on the
	       host.

5f2361f3af arm: Enable support for triggering a sim panic on kernel panics
Add the options 'panic_on_panic' and 'panic_on_oops' to the
LinuxArmSystem SimObject. When these option are enabled, the simulator
panics when the guest kernel panics or oopses. Enable panic on panic
and panic on oops in ARM-based test cases.

e5dca84c3f config: Move CPU handover logic to m5.switchCpus()
CPU switching consists of the following steps:
 1. Drain the system
 2. Switch out old CPUs (cpu.switchOut())
 3. Change the system timing mode to the mode the new CPUs require
 4. Flush caches if switching to hardware virtualization
 5. Inform new CPUs of the handover (cpu.takeOverFrom())
 6. Resume the system

m5.switchCpus() previously only did step 2 & 5. Since information
about the new processors' memory system requirements is now exposed,
do all of the steps above.

This patch adds automatic memory system switching and flush (if
needed) to switchCpus(). Additionally, it adds optional draining to
switchCpus(). This has the following implications:

* changeToTiming and changeToAtomic are no longer needed, so they have
  been removed.

* changeMemoryMode is only used internally, so it is has been renamed
  to be private.

* switchCpus requires a reference to the system containing the CPUs as
  its first parameter.

WARNING: This changeset breaks compatibility with existing
configuration scripts since it changes the signature of
m5.switchCpus().

c4898b15bc mem: Add DDR3 and LPDDR2 DRAM controller configurations
This patch moves the default DRAM parameters from the SimpleDRAM class
to two different subclasses, one for DDR3 and one for LPDDR2. More can
be added as we go forward.

The regressions that previously used the SimpleDRAM are now using
SimpleDDR3 as this is the most similar configuration.

5fb00e1df6 tests: Add CPU switching tests
This changeset adds a set of tests that stress the CPU switching
code. It adds the following test configurations:

 * tsunami-switcheroo-full -- Alpha system (atomic, timing, O3)
 * realview-switcheroo-atomic -- ARM system (atomic<->atomic)
 * realview-switcheroo-timing -- ARM system (timing<->timing)
 * realview-switcheroo-o3 -- ARM system (O3<->O3)
 * realview-switcheroo-full -- ARM system (atomic, timing, O3)

Reference data is provided for the 10.linux-boot test case. All of the
tests trigger a CPU switch once per millisecond during the boot
process.

The in-order CPU model was not included in any of the tests as it does
not support CPU handover.

e65de3f5ca config: Do not use hardcoded physmem in fs script
This patch generalises the address range resolution for the I/O cache
and I/O bridge such that they do not assume a single memory. The patch
involves adding a parameter to the system which is then defined based
on the memories that are to be visible from the I/O subsystem, whether
behind a cache or a bridge.

The change is needed to allow interleaved memory controllers in the
system.

1da209140c cpu: Add support for protobuf input for the trace generator
This patch adds support for reading input traces encoded using
protobuf according to what is done in the CommMonitor.

A follow-up patch adds a Python script that can be used to convert the
previously used ASCII traces to protobuf equivalents. The appropriate
regression input is updated as part of this patch.

9c5ef235cc tests: Add support for skipping tests, skip EIO tests if not enabled
The EIO tests depend on the EIO support from the "encumbered"
repository, which means that they are not normally built with
gem5. This causes all EIO related tests to fail, which is both
annoying and confusing. This patch addresses this by adding support
for skipping tests if certain conditions (e.g., the presence of a
SimObject) can not be met. It introduces the following Python
functions that can be called from within a test case:

  * skip_test -- Skip a test and optionally print why the test was
                 skipped.

  * has_sim_object -- Test if a SimObject exists.

  * require_sim_object -- Test if a SimObject exists and skip, or
                          optionally fail, the test if not.

Additionally, this patch updates the EIO tests to check for the
presence of EioProcess.

f456c7983d mem: Add tracing support in the communication monitor
This patch adds packet tracing to the communication monitor using a
protobuf as the mechanism for creating the trace.

If no file is specified, then the tracing is disabled. If a file is
specified, then for every packet that is successfully sent, a protobuf
message is serialized to the file.

3db3f83a5e arch: Make the ISA class inherit from SimObject
The ISA class on stores the contents of ID registers on many
architectures. In order to make reset values of such registers
configurable, we make the class inherit from SimObject, which allows
us to use the normal generated parameter headers.

This patch introduces a Python helper method, BaseCPU.createThreads(),
which creates a set of ISAs for each of the threads in an SMT
system. Although it is currently only needed when creating
multi-threaded CPUs, it should always be called before instantiating
the system as this is an obvious place to configure ID registers
identifying a thread/CPU.

90bd20aae2 tests: Always specify memory mode in every test system.
Previous to this change we didn't always set the memory mode which worked as
long as we never attempted to switch CPUs or checked that a CPU was in a
memory system with the correct mode. Future changes will make CPUs verify
that they're operating in the correct mode and thus we need to always set it.

f32f372455 tests: Create base classes to encapsulate common test configurations
Most of the test cases currently contain a large amount of duplicated
boiler plate code. This changeset introduces a set of classes that
encapsulates most of the functionality when setting up a test
configuration.

The following base classes are introduced:
* BaseSystem - Basic system configuration that can be used for both
               SE and FS simulation.

* BaseFSSystem - Basic FS configuration uni-processor and multi-processor
                 configurations.

* BaseFSSystemUniprocessor - Basic FS configuration for uni-processor
                             configurations. This is provided as a way
			     to make existing test cases backwards
			     compatible.

Architecture specific implementations are provided for ARM, Alpha, and
X86.
