b63631536d stats: Cumulative stats update
This patch updates the stats to reflect the: 1) addition of the
internal queue in SimpleMemory, 2) moving of the memory class outside
FSConfig, 3) fixing up of the 2D vector printing format, 4) specifying
burst size and interface width for the DRAM instead of relying on
cache-line size, 5) performing merging in the DRAM controller write
buffer, and 6) fixing how idle cycles are counted in the atomic and
timing CPU models.

The main reason for bundling them up is to minimise the changeset
size.

5a15909bac stats: Update stats for monitor, cache and bus changes
This patch removes the sparse histogram total from the CommMonitor
stats. It also bumps the stats after the unit fixes in the atomic
cache access. Lastly, it updates the stats to match the new port
ordering. All numbers are the same, and the only thing that changes is
which master corresponds to what port index.

4de3205afa config: Add a BaseSESystem builder for re-use in regressions
This patch extends the existing system builders to also include a
syscall-emulation builder. This builder is deployed in all
syscall-emulation regressions that do not involve Ruby,
i.e. o3-timing, simple-timing and simple-atomic, as well as the
multi-processor regressions o3-timing-mp, simple-timing-mp and
simple-atomic-mp (the latter are only used by SPARC at this point).

The values chosen for the cache sizes match those that were used in
the existing config scripts (despite being on the large
side). Similarly, a mem_class parameter is added to the builder base
class to enable simple-atomic to use SimpleMemory and o3-timing to use
the default DDR3 configuration.

Due to the different order the ports are connected, the bus stats get
shuffled around for the multi-processor regressions. A separate patch
bumps the port indices. Besides this, all behaviour is exactly the
same.

247e4e9ab4 stats: updates due to changes to ruby
Ruby's controller statistics have been mostly moved to stats.txt now.
Plus stats.txt for solaris/t1000-simple-atomic and arm/20.parser are
also being updated.

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.

53b713fb4b stats: Bump Ruby stats for new changesets
The new changeset that can reorder Ruby profilers will cause the ruby.stats
files to reordered statistics (the point of the patch). Update the references
to ensure that these changes are reflected in regressions.

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.

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.

and a whole bunch of stats are added for the memory controller.
