ecd4bad351 config: Add soak test for memtest.py
This patch adds a random option to memtest.py which allows the user to
easily test valid random tree topologies. The patch also adds a
wrapper script to run soak tests using the newly introduced option.

We also adjust the progress interval and progress limit check to make
the output less noisy, and avoid false positives.

Bring on the pain.

5a573762d0 style: Fix broken m5format command
The m5format command didn't actually work due to parameter handling
issues and missing language detection. This changeset fixes those

267443fa22 style: Fix incorrect style checker option name
The style used to support the option -w to automatically fix white

styles issues the checker encountered. This changeset cleans up the
code that handles automatic fixing and adds an option to fix all
issues, and separate options for white spaces and include ordering.

9aad5b4569 style: Update the style checker to handle new include order
As of August 2014, the gem5 style guide mandates that a source file's
primary header is included first in that source file. This helps to
ensure that the header file does not depend on include file ordering
and avoids surprises down the road when someone tries to reuse code.

In the new order, include files are grouped into the following blocks:
  * Primary header file (e.g., foo.hh for foo.cc)
  * Python headers
  * C system/stdlib includes
  * C++ stdlib includes
  * Include files in the gem5 source tree

Just like before, include files within a block are required to be
sorted in alphabetical order.

This changeset updates the style checker to enforce the new order.

e5e5b80690 config: Fix to SystemC example's event handling
This patch fixes checkpoint restore in the SystemC hosting example by handling
early PollEvent events correctly before any EventQueue events are posted.

The SystemC event queue handler (SCEventQueue) reports an error if the event
loop is entered with no Events posted.  It is possible for this to happen
after instantiate due to PollEvent events.  This patch separates out
`external' events into a different handler in sc_module.cc to prevent the
error from occurring.

This fix also improves the event handling of asynchronous events by:

    1) Making asynchronous events 'catch up' gem5 time to SystemC
        time to avoid the appearance that events have been lost
        while servicing an asynchronous event that schedules an
        event loop exit event

    2) Add an in_simulate data member to Module to allow the event
        loop to check whether events should be processed or deferred
        until the next time Module::simulate is entered

    3) Cancel pending events around the entry/exit of the event loop
        in Module::simulate

    4) Moving the state initialisation of the example entirely into
        run to correct a problem with early events in checkpoint
        restore.

It is still possible to schedule asynchronous events (and talk PollQueue
actions) while simulate is not running.  This behaviour may stil cause
some problems.

05bba75cdc config: SystemC Gem5Control top level additions
This patch cleans up a few style issues and adds a few capabilities to the
SystemC top level 'Gem5Control/Gem5System' mechanism.  These include:

    1) A space to store/retrieve a version string for a model
    2) A mechanism for registering functions to be called at the end of
        elaboration to perform simulation setup tasks in SystemC
    3) Adding setGDBRemotePort to the Gem5Control
    4) Changing the sc_set_time_resolution behaviour to instead check that
        the SystemC time resolution is already acceptable

27b7b9e561 config: Fix checkpoint restore in C++ config example
This patch fixes the checkpoint restore option in the example of C++
configuration (util/cxx_config).

The fix introduces a call to config_manager->startup() (which calls startup
on all SimObjects managed by that manager) to replicate the loop of
SimObject::startup calls in src/python/m5/simulate.py::simulate guarded by
need_startup.  As util/cxx_config/main.cc is a C++ analogue of
src/python/mt/simulate.py, it should make a similar set of calls.

83f7e7afaf sim: SystemC hosting
This patch hosts gem5 onto SystemC scheduler. There's already an upstream
review board patch that does something similar but this patch ...:

 1) is less obtrusive to the existing gem5 code organisation. It's divided
 into the 'generic' preparatory patches (already submitted) and this patch
 which affects no existing files

 2) does not try to exactly track the gem5 event queue with notifys into
 SystemC and so doesn't requive the event queue to be modified for
 anything other than 'out of event queue' scheduling events

 3) supports debug logging with SC_REPORT

The patch consists of the files:
    util/systemc/
        sc_gem5_control.{cc,hh} -- top level objects to use to
                                   instantiate gem5 Systems within
                                   larger SystemC test harnesses as
                                   sc_module objects
        sc_logger.{cc,hh}       -- logging support
        sc_module.{cc,hh}       -- a separated event loop specific to
                                   SystemC
        stats.{cc,hh}           -- example Stats handling for the sample
                                   top level
        main.{cc,hh}            -- a sample top level

On the downside this patch is only currently functional with C++
configuration at the top level.

The above sc_... files are indended to be compiled alongside gem5 (as a
library, see main.cc for a command line and util/systemc/README for
more details.)

The top-level system instantiation in sc_gem5_control.{cc,hh} provides
two classes: Gem5Control and Gem5System

Gem5Control is a simulation control class (from which a singleton
object should be created) derived from Gem5SystemC::Module which
carries the top level simulation control interface for gem5.  This
includes hosting a system-building configuration file and
instantiating the Root object from that file.

Gem5System is a base class for instantiating renamed gem5 Systems
from the config file hosted by the Gem5Control object.  In use, a
SystemC module class should be made which represents the desired,
instantiable gem5 System.  That class's instances should create
a Gem5System during their construction, set the parameters of that
system and then call instantiate to build that system.  If this
is all carried out in the sc_core::sc_module-derived classes
constructor, the System's external ports will become children of
that module and can then be recovered by name using sc_core::
sc_find_object.

It is intended that this interface is used with dlopen.  To that
end, the header file sc_gem5_control.hh includes no other header
files from gem5 (and so can be easily copied into another project).
The classes Gem5System and Gem5Control have all their member
functions declared `virtual' so that those functions can be called
through the vtable acquired by building the top level Gem5Control
using dlsym(..., "makeGem5Control") and `makeSystem' on the
Gem5Control.

66df7b7fd4 config: Add the ability to read a config file using C++ and Python
This patch adds the ability to load in config.ini files generated from
gem5 into another instance of gem5 built without Python configuration
support. The intended use case is for configuring gem5 when it is a
library embedded in another simulation system.

A parallel config file reader is also provided purely in Python to
demonstrate the approach taken and to provided similar functionality
for as-yet-unknown use models. The Python configuration file reader
can read both .ini and .json files.

C++ configuration file reading:

A command line option has been added for scons to enable C++ configuration
file reading: --with-cxx-config

There is an example in util/cxx_config that shows C++ configuration in action.
util/cxx_config/README explains how to build the example.

Configuration is achieved by the object CxxConfigManager. It handles
reading object descriptions from a CxxConfigFileBase object which
wraps a config file reader. The wrapper class CxxIniFile is provided
which wraps an IniFile for reading .ini files. Reading .json files
from C++ would be possible with a similar wrapper and a JSON parser.

After reading object descriptions, CxxConfigManager creates
SimObjectParam-derived objects from the classes in the (generated with this
patch) directory build/ARCH/cxx_config

CxxConfigManager can then build SimObjects from those SimObjectParams (in an
order dictated by the SimObject-value parameters on other objects) and bind
ports of the produced SimObjects.

A minimal set of instantiate-replacing member functions are provided by
CxxConfigManager and few of the member functions of SimObject (such as drain)
are extended onto CxxConfigManager.

Python configuration file reading (configs/example/read_config.py):

A Python version of the reader is also supplied with a similar interface to
CxxConfigFileBase (In Python: ConfigFile) to config file readers.

The Python config file reading will handle both .ini and .json files.

The object construction strategy is slightly different in Python from the C++
reader as you need to avoid objects prematurely becoming the children of other
objects when setting parameters.

Port binding also needs to be strictly in the same port-index order as the
original instantiation.

19ca35737d util: adds a script for using DSENT
This patch adds a python script that processes the configuration and the
statistics file from a simulation run.  Configuration and activity of network
routers and links obtained from this processing is fed to DSENT via its Python
interface.  DSENT then computes the area and the power consumption of these
network components.  The script outputs these quantities to the console.

291b1f8c1f config: Update Streamline scripts and configs
Updated the stat_config.ini files to reflect new structure.

Moved to a more generic stat naming scheme that can easily handle
multiple CPUs and L2s by letting the script replace pre-defined #
symbols to CPU or L2 ids.

Removed the previous per_switch_cpus sections. Still can be used by
spelling out the stat names if necessary. (Resuming from checkpoints
no longer use switch_cpus. Only fast-forwarding does.)

0756406739 mem: Add utility script to plot DRAM efficiency sweep
This patch adds basic functionality to quickly visualise the output
from the DRAM efficiency script. There are some unfortunate hacks
needed to communicate the needed information from one script to the
other, and we fall back on (ab)using the simout to do this.

As part of this patch we also trim the efficiency sweep to stop at 512
bytes as this should be sufficient for all forseeable DRAMs.

35bc5210d3 style: Fixup strange semantics in hg m5style
The 'hg m5style' command had some rather strange semantics. When
called without arguments, it applied the style checker to all added
files and modified regions of modified files. However, when providing
a list of files, it used that list as an ignore list instead of
specifically checking those files.

This patch makes the m5style command behave more like other Mercurial
commands where the arguments are used to specify which files to work
on instead of which files to ignore.

43f1e41c02 util: Fix state leakage in the SortIncludes style verifier
There are cases where the state of a SortIncludes object gets messed
up and leaks between invocations/files. This typically happens when a
file ends with an include block (dump_block() gets called at the end
of __call__). In this case, the state of the class is not reset
between files. This bug manifests itself as ghost includes that leak
between files when applying the style hooks.

This changeset adds a reset at the beginning of the __call__ method
which ensures that the class is always in a clean state when
processing a new file.

0e8a90f06b cpu: `Minor' in-order CPU model
This patch contains a new CPU model named `Minor'. Minor models a four
stage in-order execution pipeline (fetch lines, decompose into
macroops, decompose macroops into microops, execute).

The model was developed to support the ARM ISA but should be fixable
to support all the remaining gem5 ISAs. It currently also works for
Alpha, and regressions are included for ARM and Alpha (including Linux
boot).

Documentation for the model can be found in src/doc/inside-minor.doxygen and
its internal operations can be visualised using the Minorview tool
utils/minorview.py.

Minor was designed to be fairly simple and not to engage in a lot of
instruction annotation. As such, it currently has very few gathered
stats and may lack other gem5 features.

Minor is faster than the o3 model. Sample results:

     Benchmark     |   Stat host_seconds (s)

     (on ARM, opt) | simple | o3     | minor

641e602830 mem: DRAMPower trace formatting script
This patch adds a first version of a script that processes the debug
output and generates a command trace for DRAMPower. This is work in
progress and is intended as a snapshot of ongoing work at this point.

The longer term plan is to link in DRAMPower as a library and have one
instance of the model per rank, and instantiate it based on a struct
passed from gem5. Each command will then be a call to the model and no
parsing of traces will be necessary.

4a98b0cd59 Util: Do not style check symlinks
The style checker used to traverse symlinks if they pointed to files, which can
result in style checker failure if the pointed-to file doesn't exist. This
style check is actually unnecessary, since symlinks either point to other files
that are already style checked, or files outside gem5, which shouldn't be
checked. Skip symlinks.

d9fa950396 ruby: recorder: Fix (de-)serializing with different cache block-sizes
Upon aggregating records, serialize system's cache-block size, as the
cache-block size can be different when restoring from a checkpoint. This way,
we can correctly read all records when restoring from a checkpoints, even if
the cache-block size is different.

Note, that it is only possible to restore from a checkpoint if the
desired cache-block size is smaller or equal to the cache-block size
when the checkpoint was taken; we can split one larger request into
multiple small ones, but it is not reliable to do the opposite.

c446dc40bd mem: Edit proto Packet and enhance the python script
This patch changes the decode script to output the optional fields of
the proto message Packet, namely id and flags. The flags field is set
by the communication monitor.

The id field is useful for CPU trace experiments, e.g. linking the
fetch side to decode side. It had to be renamed because it clashes
with a built in python function id() for getting the "identity" of an
object.

This patch also takes a few common function definitions out from the
multiple scripts and adds them to a protolib python module.

be4aa2b6ba dev: Fix race conditions in IDE device on newer kernels
Newer linux kernels and distros exercise more functionality in the IDE device
than previously, exposing 2 races. The first race is the handling of aborted
DMA commands would immediately report the device is ready back to the kernel
and cause already in flight commands to assert the simulator when they returned
and discovered an inconsitent device state.  The second race was due to the
Status register not being handled correctly, the interrupt status bit would get
stuck at 1 and the driver eventually views this as a bad state and logs the
condition to the terminal.  This patch fixes these two conditions by making the
device handle aborted commands gracefully and properly handles clearing the
interrupt status bit in the Status register.

fec2dea5c3 x86: Add support for m5ops through a memory mapped interface
In order to support m5ops in virtualized environments, we need to use
a memory mapped interface. This changeset adds support for that by
reserving 0xFFFF0000-0xFFFFFFFF and mapping those to the generic IPR
interface for m5ops. The mapping is done in the
X86ISA::TLB::finalizePhysical() which means that it just works for all
of the CPU models, including virtualized ones.

no regressions make use of it, but all the testers could (and perhaps
should) transition to it.

cf56619b0c arm: use -march when compiling m5op_arm.S
Using arm-linux-gnueabi-gcc 4.7.3-1ubuntu1 on Ubuntu 13.04 to compiled
the m5 binary yields the error:

m5op_arm.S: Assembler messages:
m5op_arm.S:85: Error: selected processor does not support ARM mode `bxj lr'

For each of of the SIMPLE_OPs. Apparently, this compiler doesn't like the
interworking of these code types for the default arch. Adding -march=armv7-a
makes it compile. Another alternative that I found to work is replacing the
bxj lr instruction with mov pc, lr, but I don't know how that affects the
KVM stuff and if bxj is needed.

33ab8f735d kvm: Add support for pseudo-ops on ARM
This changeset adds support for m5 pseudo-ops when running in
kvm-mode. Unfortunately, we can't trap the normal gem5 co-processor
entry in KVM (it doesn't seem to be possible to trap accesses to
non-existing co-processors). We therefore use BZJ instructions to
cause a trap from virtualized mode into gem5. The BZJ instruction is
becomes a normal branch to the gem5 fallback code when running in
simulated mode, which means that this patch does not need to change
the ARM ISA-specific code.

Note: This requires a patched host kernel.

e88e7d88b9 o3: fix tick used for renaming and issue with range selection
Fixes the tick used from rename:

  in the pipeline.
- now picks up tick on entry.

Added --store_completions flag:
- will additionally display the store completion tail in the viewer.
- this highlights periods when large numbers of stores are outstanding (>16 LSQ
  blocking)

Allows selection by tick range (previously this caused an infinite loop)

38925ff621 arm: Remove the register mapping hack used when copying TCs
In order to see all registers independent of the current CPU mode, the
ARM architecture model uses the magic MISCREG_CPSR_MODE register to
change the register mappings without actually updating the CPU
mode. This hack is no longer needed since the thread context now
provides a flat interface to the register file. This patch replaces
the CPSR_MODE hack with the flat register interface.

17b47d35e1 arch: Move the ISA object to a separate section
After making the ISA an independent SimObject, it is serialized
automatically by the Python world. Previously, this just resulted in
an empty ISA section. This patch moves the contents of the ISA to that
section and removes the explicit ISA serialization from the thread
contexts, which makes it behave like a normal SimObject during
serialization.

Note: This patch breaks checkpoint backwards compatibility! Use the
cpt_upgrader.py utility to upgrade old checkpoints to the new format.

9baa35ba80 Mem: Separate the host and guest views of memory backing store
This patch moves all the memory backing store operations from the
independent memory controllers to the global physical memory. The main
reason for this patch is to allow address striping in a future set of
patches, but at this point it already provides some useful
functionality in that it is now possible to change the number of
memory controllers and their address mapping in combination with
checkpointing. Thus, the host and guest view of the memory backing
store are now completely separate.

With this patch, the individual memory controllers are far simpler as
all responsibility for serializing/unserializing is moved to the
physical memory. Currently, the functionality is more or less moved
from AbstractMemory to PhysicalMemory without any major
changes. However, in a future patch the physical memory will also
resolve any ranges that are interleaved and properly assign the
backing store to the memory controllers, and keep the host memory as a
single contigous chunk per address range.

Functionality for future extensions which involve CPU virtualization
also enable the host to get pointers to the backing store.

    }

    static {
        System.loadLibrary("gem5OpJni");
    }
}

javac -classpath $CLASSPATH:/path/to/gem5OpJni.jar HelloWorld.java

and when running you need to make sure both the java and library path are set:

7411f348d5 util/regress: make default action a more thorough regression
Changed the --variants option to --test-variants and added a new
--compile-variants option for variants that are only compiled
(not tested).  The former still defaults to 'opt' and the latter
defaults to 'debug,fast'.

Also changed the behavior when no tests are specified from just
compiling to running the 'quick' tests.

As a result, a plain 'util/regress' invocation will now compile
(but not test) the debug and fast builds, and compile and run the
quick regressions on the opt build.  This should be the default
set of tests that are run before committing.  Since the nightly
regressions use this same script, this will also be the new
nightly regression behavior.

Test-only regressions can still be done by setting --compile=''.

947a5ba9a5 Util: Replace mkblankimage.sh with the new gem5img.py.
This change replaces the mkblankimage.sh script, used for creating new disk
images, with a new gem5img.py script. The new version is written in python
instead of bash, takes its parameters from command line arguments instead of
prompting for them, and finds a free loopback device dynamically instead of
hardcoding /dev/loop1. The file system used is now optionally configurable,
and the blank image is filled by a "hole" left by lseek and write instead of
literally filling it with zeroes.

The functionality of the new script is broken into subcommands "init",
"mount", "umount", "new", "partition", and "format". "init" creates a new file
of the appropriate size, partitions it, and then formats the first (and only)
new parition. "mount" attaches a new loopback device to the first parition of
the image file and mounts it to the specified mount point. "umount" unmounts
the specified mount point and identifies and cleans up the underlying loopback
device. "new", "partition", and "format" are the individual stages of "init"
but broken out so they can be run individually. That's so an image can be
reinitialized in place if needed.

Two features of the original script are being dropped. The first is the
ability to specify a source directory to copy into the new file system. The
second is the ability to specify a list of commands to run which are expected
to (but not required to) update the permissions of the files in the new fs.
Both of these seem easy enough to do manually, especially given the "mount"
and "umount" commands, that removing them would meaningfully simplify the
script without making it less useful.

e5ecfde222 util: python implementation of a routine that will sort includes
I didn't realize that the perl version existed when I started this,
this version has a lot more features than the previous one since it will
sort and separate python, system, and m5 headers in separate groups, it
will remove duplicates, it will also convert c headers to stl headers

ab2f864af2 m5: Regression Tester Update
This patch includes the necessary regression updates to test the new ruby
configuration system.  The patch includes support for multiple ruby protocols
and adds the ruby random tester.  The patch removes atomic mode test for
ruby since ruby does not support atomic mode acceses.  These tests can be
added back in when ruby supports atomic mode for real.

d6da172517 util: do checkpoint aggregation more cleanly, fix last changeset.
1) Move alpha-specific code out of page_table.cc:serialize().
2) Begin serializing M5_pid and unserializing it, but adding an function to do optional paramIn so that old checkpoints don't need to be fixed up.
3) Fix up alpha startup code so that the unserialized M5_pid value is properly written to DTB_IPR_ASN.
4) Fix the memory unserialize that I forgot somehow in the last changeset.
5) Add in an agg_se.py to handle aggregated checkpoints. --bench foo-bar plus positional arguments foo bar are the only changes in usage from se.py.
Note this aggregation stuff has only been tested for Alpha and nothing else, though it should take a very minimal amount of work to get it to work with another ISA.

e09ae149af Statetrace: Make sure the current state is loaded to print the initial stack frame.
The early call to child->step() was removed earlier because it confused the
new differences-only protocol ARM sendState() was using. It's necessary that
that gets called at least once before attempting to print the initial stack
frame, though, because otherwise statetrace doesn't know what the stack
pointer is. By putting the first call to child->step() in a common spot, both
needs are met.
