8dfa45e03c misc: Bugfix for Freezing Terminal in SystemC Simulation
If the terminal was used in the SystemC or TLM simulations the simulation gets
in a deadlock state. This is because of the Event queue gets locked while
servicing the async events leading to event queue deadlock. This was solved by
locking the queue at the beginning of service of async events.

f7055e9215 dev, arm: Rewrite the HDLCD controller
Rewrite the HDLCD controller to use the new DMA engine and pixel
pump. This fixes several bugs in the current implementation:

   * Broken/missing interrupt support (VSync, underrun, DMA end)
   * Fragile resolution changes (changing resolutions used
     to cause assertion errors).
   * Support for resolutions with a width that isn't divisible by 32.
   * The pixel clock can now be set dynamically.

This breaks checkpoint compatibility. Checkpoints can be upgraded with
the checkpoint conversion script. However, upgraded checkpoints won't
contain the state of the current frame. That means that HDLCD
controllers restoring from a converted checkpoint immediately start
drawing a new frame (i.e, expect timing differences).

87b9da2df4 sim: tag-based checkpoint versioning
This commit addresses gem5 checkpoints' linear versioning bottleneck.
Since development is distributed across many private trees, there exists
a sort of 'race' for checkpoint version numbers: internally a checkpoint
version may be used but then resynchronizing with the external tree causes
a conflict on that version.  This change replaces the linear version number
with a set of unique strings called tags.  Now the only conflicts that can
arise are of tag names, where collisions are much easier to avoid.

The checkpoint upgrader (util/cpt_upgrader.py) upgrades the version
representation, as one would expect. Each tag version implements its
upgrader code in a python file in the util/cpt_upgraders directory
rather than adding a function to the upgrader script itself.

The version tags are stored in the 'Globals' section rather than 'root'
(as the version was previously) because 'Globals' gets unserialized
first and can provide a warning before any other unserialization errors
can occur.

d540ba0325 util: Enable DRAM sweep to print power and efficiency
This patch enhances the functionality of the DRAM sweep script to not
only plot the bandwidth utilisation, but also total power and power
efficiency. To do so, a command-line switch is added, and a bit more
data extracted from the stats.

8723b08dbf misc: Coupling gem5 with SystemC TLM2.0
Transaction Level Modeling (TLM2.0) is widely used in industry for creating
virtual platforms (IEEE 1666 SystemC). This patch contains a standard compliant
implementation of an external gem5 port, that enables the usage of gem5 as a
TLM initiator component in SystemC based virtual platforms. Both TLM coding
paradigms loosely timed (b_transport) and aproximately timed (nb_transport) are
supported.

Compared to the original patch a TLM memory manager was added. Furthermore, the
transaction object was removed and for each TLM payload a PacketPointer that
points to the original gem5 packet is added as an TLM extension.  For event
handling single events are now created.

concise C++11 version.  As part of the changes, the FdMap class is pulled out
of the Process class and receives its own file.

fc5bf6713f dev: add support for multi gem5 runs
Multi gem5 is an extension to gem5 to enable parallel simulation of a
distributed system (e.g. simulation of a pool of machines
connected by Ethernet links). A multi gem5 run consists of seperate gem5
processes running in parallel (potentially on different hosts/slots on
a cluster). Each gem5 process executes the simulation of a component of the
simulated distributed system (e.g. a multi-core board with an Ethernet NIC).

The patch implements the "distributed" Ethernet link device
(dev/src/multi_etherlink.[hh.cc]). This device will send/receive
(simulated) Ethernet packets to/from peer gem5 processes. The interface
to talk to the peer gem5 processes is defined in dev/src/multi_iface.hh and
in tcp_iface.hh.

There is also a central message server process (util/multi/tcp_server.[hh,cc])
which acts like an Ethernet switch and transfers messages among the gem5 peers.

A multi gem5 simulations can be kicked off by the util/multi/gem5-multi.sh
wrapper script.

Checkpoints are supported by multi-gem5. The checkpoint must be
initiated by a single gem5 process. E.g., the gem5 process with rank 0
can take a checkpoint from the bootscript just before it invokes
'mpirun' to launch an MPI test. The message server process will notify
all the other peer gem5 processes and make them take a checkpoint, too
(after completing a global synchronisation to ensure that there are no
inflight messages among gem5).

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.

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.

no longer use switch_cpus. Only fast-forwarding does.)

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

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)

This patch adds a first version of a script that processes the debug

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.

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.

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.

612f8f074f arm: Add support for ARMv8 (AArch64 & AArch32)
Note: AArch64 and AArch32 interworking is not supported. If you use an AArch64
kernel you are restricted to AArch64 user-mode binaries. This will be addressed
in a later patch.

Note: Virtualization is only supported in AArch32 mode. This will also be fixed
in a later patch.

59a041c5e7 util: update checkpoint aggregation script
The checkpoint aggregation script had become outdated due to numerous changes
to checkpoints over the past couple of years.  This updates the script.  It
now supports aggregation for x86 architecture instead of alpha.  Also a couple
of new options have been added that specify the size of the memory file to be
created and whether or not the memory file should be compressed.

3e6da89419 ARM: add support for TEEHBR access
Thumb2 ARM kernels may access the TEEHBR via thumbee_notifier
in arch/arm/kernel/thumbee.c.  The Linux kernel code just seems
to be saving and restoring the register.  This patch adds support
for the TEEHBR cp14 register.  Note, this may be a special case
when restoring from an image that was run on a system that
supports ThumbEE.
