The commit that refactored the style checkers into a new Python
package (style: Refactor the style checker as a Python package)
accidentally left a fragment of file_types.py in the old location
(util/style.py). This was caused by a race between the commit that
moved the file and Nate's commit that added a copyright header to the
file.
This commit moves the last fragment (the copyright header) and removes
the old file.

The git style hook currently includes a few lines of diff context when
determining changed regions. This is undesirable as this triggers
false positives when modifying existing files with a lot of style
violations. This change sets the amount of context to 0, which is the
default value when requesting staged regions from the git helper.

The style checker code needs to disable autojunk when diffing source
files using Python's difflib. Support for this was only introduced in
Python 2.7, which leads to a TypeError exception on older Python
version. This changeset adds a fallback mechanism for old Python
versions.

memInhibitAsserted() has been removed from packet.hh. This change has been
reflected in TLM based SystemC memory.
This patch also adds a number of panics asserting the SystemC memory only
sees requests it expects.

Distributed gem5 is the result of the convergence effort between
multi-gem5 and pd-gem5. It relies on the base multi-gem5 infrastructure
for packet forwarding, synchronisation and checkpointing but combines
those with the elaborated network switch model from pd-gem5.

The m5ops assembly library contains a lot of repetitive code. This
changeset adds two macros, FOREACH_M5OP and FOREACH_M5_ANNOTATION, to
m5ops.h that simplify architecture-specific implementations. The ARM
and ARMv8 m5op implementations have been updated to use the new
macros.

The old style guide used to mandate 78 characters as the maximum line
length to accommodate traditional diffs on 80-column terminals. This
is an uncommon use case and it has therefore been decided (see email
thread on gem5-dev [1]) that a maximum length of 79-characters makes
more sense.

The current style checker script, hgstyle.py, assumes that it is being
run from Mercurial. This means that it depends on the Mercurial Python
libraries, which aren't necessarily present if using git. This
changeset adds a new style checker script, style.py, that has
been designed to be run from the command line.
The script has support for detecting which revision control system is
used and is able to query both git and Mercurial for changes. This
enables the script to operate on modified regions and/or all of the
modified files in the repository.

Add a git pre-commit hook that verifies that files that are about to
be committed. Since git stages changes into an index and the index
contains the changes that will be committed, the style checker only
looks at the state of files in the index.

Refactor the style checker into a Python module that can be reused by
command line tools that integrate with git. In particular:
* Create a style package in util
* Move style validators from style.py to the style/validators.py.
* Move style verifiers from style.py to the style/verifiers.py.
* Move utility functions (sort_includes, region handling,
file_types) into the style package
* Move generic code from style.py to style/style.py.

The include sorter class normally yields one string per line and
relies on the caller to merge lines into a block of text separated by
newlines. However, there are cases when this isn't true. This makes
diffing using Python's difflib hard. This changeset updates the
include sorter to never do this and always yield one line at a time.

This patch adds a config script that broadly replicates the behaviour
of lat_mem_rd. The test is based on traffic generators, and as such we
simply randomise addresses in increasingly large ranges, and play them
back using the trace functionality of the traffic generator.
The test script is accompanied by a post-processing and visualisation
script. At the moment no configurability is added to tweak the memory
hierarchy, but a follow on patch could easily extend the
functionality.

Previous ARM-based simulations were limited to 8 cores due to
limitations in GICv2 and earlier. This changeset adds a set of
gem5-specific extensions that enable support for up to 256 cores.
When the gem5 extensions are enabled, the GIC uses CPU IDs instead of
a CPU bitmask in the GIC's register interface. To OS can enable the
extensions by setting bit 0x200 in ICDICTR.
This changeset is based on previous work by Matt Evans.

This patch adds support to optionally capture the virtual address and asid
for load/store instructions in the elastic traces. If they are present in
the traces, Trace CPU will set those fields of the request during replay.
|
|
This patch replaces the booleans that specified the elastic trace record
type with an enum type. The source of change is the proto message for
elastic trace where the enum is introduced. The struct definitions in the
elastic trace probe listener as well as the Trace CPU replace the boleans
with the proto message enum.
The patch does not impact functionality, but traces are not compatible with
previous version. This is preparation for adding new types of records in
subsequent patches.

This patch adds python scripts to parse a protobuf encoded O3CPU
elastic trace and convert it to a text file output and vice versa.

The DTRACE() macro tests both Trace::enabled and the specific flag. This

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.
