The default python on MacOS doesn’t have an alias to python2.
The official python version supported in gem5 is Python2.7.
This patch updates the shabang according to the version required in gem5.

In some newer Linux distributions, env python default to Python 3.0. This
patch explicitly uses "python2" instead of just "python" for all scripts
that use #!

Bug fix for check on protobuf file frequency being different than
global frequency.
The ASCII encoder script is also fixed, and the example trace used in
the regressions is updated.
|
|
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.

|
This patch adds a more verbose error message when the Python protobuf
module cannot be loaded.
|
|
This patch simplifies the usage of the packet trace encoder/decoder by
attempting to automatically generating the packet proto definitions in
case they cannot be found.
|
|
This patch adds a simple Python script that reads a simple ASCII trace
format and encodes it as protobuf output compatible with the traffic
generator.
The script can also be used as a template for other packet input
formats that should be converted to the gem5 packet protobuf format.
