These files aren't a collection of miscellaneous stuff, they're the

This change adds a script to generate graphs from the stats file
output by the configuration script low_power_sweep.py.
The graphs show stacked bars for time spent and energy consumed
wherein each component of the stacked bar represents a DRAM power
state (Idle, Refresh, Active, Active Power-down, Precharge Power-down
and Self-refresh). The script generates one plot per delay value. It
also generates a pdf (--pdf option) in which the graphs are laid out
such that you can easily compare how the increasing delay and other
swept params affect the resulting energy.

Simplify the patch creation helper script by removing support for
automatic conversion to Mercurial's patch format. We no longer use
Mercurial as a primary repository, so this support is not likely to be

The helper script to list changes currently only looks at the changes
between a branch point and two heads. This helps performance, but
sometimes misclassifies changes that exist both in the upstream
branch before the branch point and in a feature branch. Such changes
should normally not exist, but can be the product of an incorrect
rebase.
This change adds an option to the helper script to search the entire
upstream repo history when determining the set of upstream
changes. When this option is provided, the script lists the changes
that exist upstream before the branch point and in the feature branch
as "Incorrectly rebased changes".

Some internal review flows, e.g. the flow used by ARM Research, uses
the For-Upstream tag to indicate that a change has been approved for
upstream. This tag isn't meaningful outside of the internal review
system. Remove it automatically when running the maintainer script to
prepare patches to be posted upstream.

Rather than just ensuring that packet_pb2.py is available in general, use a
Makefile to ensure that it's also up to date in case packet.proto has
changed.
Also, remove a check that ensures that the protobuf module is available,
since python will complain if it needs it and can't find it.
Finally, remove a comment which talks about manually regenerating the
packet_pb2.py module, something that hasn't been necessary for a while, even
with the old version of this code.

DecodeVarint implicitly truncates its inputs to 32 bits, and that should be
obvious from its name, and so not a surprise to the caller. EncodeVarint also
has the suffix added for consistency. Both functions are only used in
protolib.py, so add a _ to make it private (in the python sense) to the
module.

The DecodeVarint was, as a comment describes, lifted from
google.protobuf.internal.decoder. Unfortunately, the relative indentation of
some lines was changed, changing what scope they fell under. This changed the
behavior of the function, breaking it for multibyte and negative values.
This change restores the correct indentation and fixes the function's
behavior.

Some simulators already set the time resolution of SystemC. By coupling
gem5 by means of SystemC with an other tool this can lead to problems:
When the resolution is set twice the simulation will not work.
Therefore, the line is changed to an assertion that checks if the time
resolution of the SystemC simulation is set to gem5's value of 1ps.

Use printf instead of cprintf to avoid having to have .o files from gem5.
Stop disabling optimization. Placate the style checker by rearranging the
header include order. Include some missing standard headers. Switch from
the deprecated -I- gcc option to using -iquote. Make the "program"
variable a const char *. When checking the return value of getopt, don't
check against the char c which may mask the -1 return value. Instead,
store the return value in an int, and then later cast it to a char when
it's actually consumed.

Basically, this patch ensures that all transactions that originated in the

world. So far, this only worked for packets that are responded to by a
SyctemC component (e.g. when a gem5 CPU sends a request to a SystemC

packets that are responded to by a gem5 component (e.g. when a gem5 CPU
sends a request to a gem5 memory via a SystemC interconnect) are handled
properly.

The current TLM bridge only provides a Slave Port that allows the gem5
world to send request to the SystemC world. This patch series refractors
and cleans up the existing code, and adds a Master Port that allows the
SystemC world to send requests to the gem5 world.
This patch:
* Add the Master Port. Add an example application that isslustrates its
* use.
Testing Done: A simple example application consisting of a TLM traffic
generator and a gem5 memory is part of the patch.

and cleans up the existing code, and adds a Master Port that allows the
SystemC world to send requests to the gem5 world.
This patch:
* Restructure the existing sources in preparation of the addition of the
* new
Master Port.
* Refractor names to allow for distinction of the slave and master port.
* Replace the Makefile by a SConstruct.
Testing Done: The examples provided in util/tlm (now
util/tlm/examples/slave_port) still compile and run error free.

Implementing the Module as an sc_channel allows derived classes to provide
SystemC interfaces. Other SystemC modules can connect to these interfaces.
This meachanism can be used to control gem5 and acces gem5 components from
within arbitrary SystemC moduels. Since sc_channel is derived from
sc_module, this patch does not break compatibility with existing code.
