a3f49f60c7 mem: Move trace functionality from the CommMonitor to a probe
This changeset moves the access trace functionality from the
CommMonitor into a separate probe. The probe can be hooked up to any
component that exports probe points of the type ProbePoints::Packet.

This patch moves the dependency on Google's Protocol Buffers library
from the CommMonitor to the MemTraceProbe, which means that the
CommMonitor (including stack distance profiling) no long depends on
it.

022e69e6de mem: Redesign the stack distance calculator as a probe
This changeset removes the stack distance calculator hooks from the
CommMonitor class and implements a stack distance calculator as a
memory system probe instead. The probe can be hooked up to any
component that exports probe points of the type ProbePoints::Packet.

447a6b6442 stats: Update switcheroo reference stats
The Minor draining fixes affect perturb the timing slightly since it
affects how the simulator is drained. Update reference statistics to
reflect this expected change.

a0cbf55411 stats: Update pc-switcheroo stats
The pc-switcheroo test cases has slightly different timing after
decoupling draining from the SimObject hierarchy. This is expected
since objects aren't drained in the exact same order as before.

f16c0a4a90 sim: Decouple draining from the SimObject hierarchy
Draining is currently done by traversing the SimObject graph and
calling drain()/drainResume() on the SimObjects. This is not ideal
when non-SimObjects (e.g., ports) need draining since this means that
SimObjects owning those objects need to be aware of this.

This changeset moves the responsibility for finding objects that need
draining from SimObjects and the Python-side of the simulator to the
DrainManager. The DrainManager now maintains a set of all objects that
need draining. To reduce the overhead in classes owning non-SimObjects
that need draining, objects inheriting from Drainable now
automatically register with the DrainManager. If such an object is
destroyed, it is automatically unregistered. This means that drain()
and drainResume() should never be called directly on a Drainable
object.

While implementing the new functionality, the DrainManager has now
been made thread safe. In practice, this means that it takes a lock
whenever it manipulates the set of Drainable objects since SimObjects
in different threads may create Drainable objects
dynamically. Similarly, the drain counter is now an atomic_uint, which
ensures that it is manipulated correctly when objects signal that they
are done draining.

A nice side effect of these changes is that it makes the drain state
changes stricter, which the simulation scripts can exploit to avoid
redundant drains.

d7a56ee524 tests: Skip SPARC tests if the required binaries are missing
The full-system SPARC tests depend on several binaries that aren't
generally available to the wider community. Flag the tests as skipped
instead of failed if these binaries can't be found.

25e1b1c1f5 stats: Update stats for cache, crossbar and DRAM changes
This update includes the changes to whole-line writes, the refinement
of Read to ReadClean and ReadShared, the introduction of CleanEvict
for snoop-filter tracking, and updates to the DRAM command scheduler
for bank-group-aware scheduling.

Needless to say, almost every regression is affected.

893533a126 mem: Allow read-only caches and check compliance
This patch adds a parameter to the BaseCache to enable a read-only
cache, for example for the instruction cache, or table-walker cache
(not for x86). A number of checks are put in place in the code to
ensure a read-only cache does not end up with dirty data.

A follow-on patch adds suitable read requests to allow a read-only
cache to explicitly ask for clean data.

The change in 20.parser is from new x87 instructions.  The change to

ed08dc31ba tests: Final reclassification of quick regressions
A few regressions were still considered long, but finished well within
the 180 seconds. They are only a handful (mostly mcf in atomic).

1483496803 stats: update Minor stats due to PF bug fix
A recent changeset of mine (http://repo.gem5.org/gem5/rev/4cfe55719da5)
inadvertently fixed a bug in the Minor CPU model which caused it to treat
software prefetches as regular loads.  Prior to this changeset, Minor
did an ad-hoc generation of memory commands that left out the PF check;
because it now uses the common code that the other CPU models use,
it generates prefetches properly.  These stat changes reflect the fact
that the Minor model now issues SoftPFReqs.

f1c3fda965 tests: Recategorise regressions based on run time
This patch takes a first stab at recategorising the regression tests
based on actual run times. The simple-atomic and simple-timing runs of
vortex and twolf all finish in less than 180 s, and they are
consequently moved from long to quick. All realview64 linux-boot
regressions take more than 700 s, and they are therefore moved to
long.

Later patches will rename quick to short, and further divide the
regressions into short, medium and long.

877435950c test, arm: Add scripts to test checkpoints
Add a set of scripts to automatically test checkpointing in the
regression framework. The checkpointing tests are similar to the
switcheroo tests, but instead of switching between CPUs, they
checkpoint the system and restore from the checkpoint again. This is
done at regular intervals, typically while booting Linux.

The implementation is fairly straight forward, with the exception that
we have to work around gem5's inability to restore from a checkpoint
after a system has been instantiated. We work around this by forking
off child processes that does the actual simulation and never
instantiate a system in the parent process unless a maximum checkpoint
count is reached (in which case we just simulate the system to
completion in the parent).

Checkpoint testing is currently only enabled 32- and 64-bit ARM
systems using atomic CPUs.

Note: An unfortunate side-effect of forking is that every new process
will overwrite the stats and terminal output from the previous
process. This means that the output directory only contains data from
the last checkpoint.

36dc93a5fa mem: Move crossbar default latencies to subclasses
This patch introduces a few subclasses to the CoherentXBar and
NoncoherentXBar to distinguish the different uses in the system. We
use the crossbar in a wide range of places: interfacing cores to the
L2, as a system interconnect, connecting I/O and peripherals,
etc. Needless to say, these crossbars have very different performance,
and the clock frequency alone is not enough to distinguish these
scenarios.

Instead of trying to capture every possible case, this patch
introduces dedicated subclasses for the three primary use-cases:
L2XBar, SystemXBar and IOXbar. More can be added if needed, and the
defaults can be overridden.

6563ec8634 cpu: Tidy up the MemTest and make false sharing more obvious
The MemTest class really only tests false sharing, and as such there
was a lot of old cruft that could be removed. This patch cleans up the
tester, and also makes it more clear what the assumptions are. As part
of this simplification the reference functional memory is also
removed.

The regression configs using MemTest are updated to reflect the
changes, and the stats will be bumped in a separate patch. The example
config will be updated in a separate patch due to more extensive
re-work.

In a follow-on patch a new tester will be introduced that uses the
MemChecker to implement true sharing.

3022d463fb ruby: interface with classic memory controller
This patch is the final in the series.  The whole series and this patch in
particular were written with the aim of interfacing ruby's directory controller
with the memory controller in the classic memory system.  This is being done
since ruby's memory controller has not being kept up to date with the changes
going on in DRAMs.  Classic's memory controller is more up to date and
supports multiple different types of DRAM.  This also brings classic and
ruby ever more close.  The patch also changes ruby's memory controller to
expose the same interface.

95a0b18431 ruby: single physical memory in fs mode
Both ruby and the system used to maintain memory copies.  With the changes
carried for programmed io accesses, only one single memory is required for
fs simulations.  This patch sets the copy of memory that used to reside
with the system to null, so that no space is allocated, but address checks
can still be carried out.  All the memory accesses now source and sink values
to the memory maintained by ruby.

c4e91289ae stats: Bump stats for filter, crossbar and config changes
This patch bumps the stats to reflect the addition of the snoop filter
and snoop stats, the change from bus to crossbar, and the updates to
the ARM regressions that are now using a different CPU and cache
configuration. Lastly, some minor changes are expected due to the
activation cleanup of the CPUs.

1f6d5f8f84 mem: Rename Bus to XBar to better reflect its behaviour
This patch changes the name of the Bus classes to XBar to better
reflect the actual timing behaviour. The actual instances in the
config scripts are not renamed, and remain as e.g. iobus or membus.

As part of this renaming, the code has also been clean up slightly,
making use of range-based for loops and tidying up some comments. The
only changes outside the bus/crossbar code is due to the delay
variables in the packet.

db430698bf tests: Use medium dataset for perlbmk regressions
This patch changes the perlbmk regression script from the large to the
medium dataset to reduce the regression run time. For all ISAs and CPU
models, the total perlbmk host CPU time with the large dataset is
roughly 12 hours (constituting >30% of the total regression host
time). There is, most likely, almost no added value in terms of code
coverage for this rather excessive run time.

01f792a367 ruby: Fixes clock domains in configuration files
This patch fixes scripts related to ruby by adding the ruby clock domain.
Now the L1 controllers and  the Sequencer shares the cpu clock domain,
while the rest of the components use the ruby clock domain.

Before this patch, running simulations with the cpu clock set at 2GHz or
1GHz will output the same time results and could distort power measurements.

fe27f937aa arch: teach ISA parser how to split code across files
This patch encompasses several interrelated and interdependent changes
to the ISA generation step.  The end goal is to reduce the size of the
generated compilation units for instruction execution and decoding so
that batch compilation can proceed with all CPUs active without
exhausting physical memory.

The ISA parser (src/arch/isa_parser.py) has been improved so that it can
accept 'split [output_type];' directives at the top level of the grammar
and 'split(output_type)' python calls within 'exec {{ ... }}' blocks.
This has the effect of "splitting" the files into smaller compilation
units.  I use air-quotes around "splitting" because the files themselves
are not split, but preprocessing directives are inserted to have the same
effect.

Architecturally, the ISA parser has had some changes in how it works.
In general, it emits code sooner.  It doesn't generate per-CPU files,
and instead defers to the C preprocessor to create the duplicate copies
for each CPU type.  Likewise there are more files emitted and the C
preprocessor does more substitution that used to be done by the ISA parser.

Finally, the build system (SCons) needs to be able to cope with a
dynamic list of source files coming out of the ISA parser. The changes
to the SCons{cript,truct} files support this. In broad strokes, the
targets requested on the command line are hidden from SCons until all
the build dependencies are determined, otherwise it would try, realize
it can't reach the goal, and terminate in failure. Since build steps
(i.e. running the ISA parser) must be taken to determine the file list,
several new build stages have been inserted at the very start of the
build. First, the build dependencies from the ISA parser will be emitted
to arch/$ISA/generated/inc.d, which is then read by a new SCons builder
to finalize the dependencies. (Once inc.d exists, the ISA parser will not
need to be run to complete this step.) Once the dependencies are known,
the 'Environments' are made by the makeEnv() function. This function used
to be called before the build began but now happens during the build.
It is easy to see that this step is quite slow; this is a known issue
and it's important to realize that it was already slow, but there was
no obvious cause to attribute it to since nothing was displayed to the
terminal. Since new steps that used to be performed serially are now in a
potentially-parallel build phase, the pathname handling in the SCons scripts
has been tightened up to deal with chdir() race conditions. In general,
pathnames are computed earlier and more likely to be stored, passed around,
and processed as absolute paths rather than relative paths.  In the end,
some of these issues had to be fixed by inserting serializing dependencies
in the build.

Minor note:
For the null ISA, we just provide a dummy inc.d so SCons is never
compelled to try to generate it. While it seems slightly wrong to have
anything in src/arch/*/generated (i.e. a non-generated 'generated' file),
it's by far the simplest solution.

e940bac278 mem: Auto-generate CommMonitor trace file names
Splits the CommMonitor trace_file parameter into three parameters. Previously,
the trace was only enabled if the trace_file parameter was set, and would be
written to this file. This patch adds in a trace_enable and trace_compress
parameter to the CommMonitor.

No trace is generated if trace_enable is set to False. If it is set to True, the
trace is written to a file based on the name of the SimObject in the simulation
hierarchy. For example, system.cluster.il1_commmonitor.trc. This filename can be
overridden by additionally specifying a file name to the trace_file parameter
(more on this later).

The trace_compress parameter will append .gz to any filename if set to True.
This enables compression of the generated traces. If the file name already ends
in .gz, then no changes are made.

The trace_file parameter will override the name set by the trace_enable
parameter. In the case that the specified name does not end in .gz but
trace_compress is set to true, .gz is appended to the supplied file name.
