Starting with version 3, scons imposes using the print function instead
of the print statement in code it processes. To get things building
again, this change moves all python code within gem5 to use the
function version. Another change by another author separately made this
same change to the site_tools and site_init.py files.

This patch adds an extra layer to the pyfdt library such that usage
gets easier and device tree nodes can be specified in less code,
without limiting original usage. Note to not import both the pyfdt
and fdthelper in the same namespace (but generally fdthelper is all
you need, because it supplies the same classes even when they are not
extended in any way)
Also, this patch lays out the primary functionality for generating a
device tree, where every SimObject gets an empty generateDeviceTree
method and ArmSystems loop over their children in an effort to merge
all the nodes. Devices are implemented in other patches.

This patch adds pyfdt.py to the m5.ext module. This is used in
succeeding patches for generating and editing dtb files and flat
device trees for DT autogeneration.
The file is in the m5_root/src/python/m5/ext directory, as opposed to
the m5_root/ext, because this library is part of the m5 object space
and linking to the m5_root/ext directory from the SConscript file
in src/python can not be done reliably. Linking from the root level
SConscript is also not an option, because it doesn't have the PySource
method defined.

Tags are just arbitrary strings which are attached to source files
which mark them as having some property. By default, all source files
have the "gem5 lib" tag added to them which marks them as part of the
gem5 library, the primary component of the gem5 binary but also a
seperable component for use in, for example, system C.
The tags can be completely overridden by setting the "tags" parameter
on Source, etc., functions, and can be augmented by setting "add_tags"
which are tags that will be added, or alternatively additional tags.
It's possible to specify both, in which case the tags will be set to
the union of tags and add_tags. add_tags is supposed to be a way to
add extra tags to the default without actually overriding the default.
Both tags and add_tags can be a list/tuple/etc of tags, or a single
string which will be converted into a set internally.
Other existing tags include:
1. "python" for files that need or are used with python and are
excluded when the --without-python option is set
2. "main" for the file(s) which implement the gem5 binary's main
function.
3. The name of a unit test to group its files together.
4. Tags which group source files for partial linking.
By grouping the "tags" into a single parameter instead of taking all
extra parameters as tags, the extra parameters can, in the future, be
passed to the underlying scons environment. Also, the tags are either
present or not. With guards, they could be present and True, present
and False, or not present at all.

The python conversion module was really repetitive and fragmented,
where some types of conversions use common code, and some use hand
written case statements which did something very similar. Also, some
types like Voltage could only handle V and mV but no other scaling
prefix.
This change restructures the module to centralize a lot of the unit
handling code into toFloat, and makes the various other functions use
it.

The existing code was essentially doing the same thing, but in a more
roundabout and obscure way. One difference between the two versions is that
I believe this will stop as soon as it encounters an element without a
parent, where the original version would call has_parent() on all the
elements regardless.

NullSimObject doesn't have a has_parent function, and it's not clear what its
return value should be if one were added. The appropriate value seems to
depend on why some other bit of code is checking if there's a parent in the
first place.
In SimObjectVector, the has_parent function is checking whether all of its
elements have a parent. In this particular case, the most reasonable thing
to do seems to be to just skip those elements.

PyBind normally casts integers returned from the C to long in
Python. This is normally fine since long in most cases behaves just
like an int. However, when passing the return value from getcode() to
sys.exit, unexpected behavior ensues. Due to the way the function is
defined, any type other than int (with the exception of None) will be
treated as an error and be equivalent to sys.exit(1).
Since we frequently use the sys.exit(event.getCode()) pattern, we need
to ensure that the function returns an integer. This change adds an
explicit type conversion to a Python integer in the wrapper code.

Previously proxy vector parameters would resolve correctly only for
Parent.all. Any other proxy such as Parent.any, or exact ones such as
Parent.addr_range would resolve to a *vector* of the right value
resulting into a vector of a vector. For example if we set:
DirectoryController0.addr_range = [0x100000-0x1fffff, 0x200000-0x2fffff]
DirectoryMemory0.addr_range = Parent.addr_range
where DirectoryController0 is the parent SimObject of DirectoryMemory0
after unproxying the Parent.addr_range VectorParam we would get
DirectoryMemory0.addr_range = [[0x100000-0x1fffff, 0x200000-0x2fffff]]
This change unifies handling of all three proxies to the same correct
unproxy mechanism.

The current implementation of reference counting for PyEvents only
partially works. The native object is currently kept alive while it is
in the event queue. However, if the Python object goes out of scope,
the Python side of this object is garbage collected which leaves a
"dangling" native object. This results in confusing error messages
where PyBind is unable to find the Python implementation of an event
when it is triggered.
Implement reference counting using the generalized reference counting
API instead.

The PyBind wrappers could potentially delete SimObjects if they don't
have any references. This is not desirable since there could be
pointers to such objects within the C++ world. This problem doesn't
normally occur since Python typically holds a pointer to the root node
as long as the simulator is running.
Prevent SimObject and Param deletion by using a PyBind-prescribed
unique_ptr with a dummy deleter as the pointer wrapper for the Python
world.

There is a weird issue with the PyBind wrapper of

AddrRange sometimes results in an out-of-bounds memory access.
We work around this issue by treating AddrRange vectors as opaque
types. This slightly changes the semantics of the wrapper since Python
now manipulates the real object rather than a copy that has been
converted to a list.

Use the PyBind11 wrapping infrastructure instead of SWIG to generate
wrappers for functionality that needs to be exported to Python. This
has several benefits:
* PyBind11 can be redistributed with gem5, which means that we have
full control of the version used. This avoid a large number of
hard-to-debug SWIG issues we have seen in the past.
* PyBind11 doesn't rely on a custom C++ parser, instead it relies on
wrappers being explicitly declared in C++. The leads to slightly
more boiler-plate code in manually created wrappers, but doesn't
doesn't increase the overall code size. A big benefit is that this
avoids strange compilation errors when SWIG doesn't understand
modern language features.
* Unlike SWIG, there is no risk that the wrapper code incorporates
incorrect type casts (this has happened on numerous occasions in
the past) since these will result in compile-time errors.
As a part of this change, the mechanism to define exported methods has
been redesigned slightly. New methods can be exported either by
declaring them in the SimObject declaration and decorating them with
the cxxMethod decorator or by adding an instance of
PyBindMethod/PyBindProperty to the cxx_exports class variable. The
decorator has the added benefit of making it possible to add a
docstring and naming the method's parameters.
The new wrappers have the following known issues:
* Global events can't be memory managed correctly. This was the
case in SWIG as well.

It's currently possible to change the log level in gem5 by tweaking a
set of global variables. These variables are currently exposed to
Python using SWIG. This mechanism is far from ideal for two reasons:
First, changing the log level requires that the Python world enables
or disables individual levels. Ideally, this should be a single call
where a log level is selected. Second, exporting global variables is
poorly supported by most Python frameworks. SWIG puts variables in
their own namespace and PyBind doesn't seem to support it at all.
This changeset refactors the logging code to create a more abstract
interface. Each log level is associated with an instance of a Logger
class. This class contains common functionality, an enable flag, and a
verbose flag.
Available LogLevels are described by the LogLevel class. Lower log
levels are used for more critical messages (PANIC being level 0) and
higher levels for less critical messages. The highest log level that
is printed is controlled by calling Logger:setLevel().

Add a mechanism to configure the stat output format using a URL-like
syntax. This makes it possible to specify both an output format
(currently, only text is supported) and override default
parameters.
On the Python-side, this is implemented using a helper function
(m5.stats.addStatVisitor) that adds a visitor to the list of active
stat visitors. The helper function parses a URL-like stat
specification to determine the stat output type. Optional parameters
can be specified to change how stat visitors behave.
For example, to output stats in text format without stat descriptions:
m5.stats.addStatVisitor("text://stats.txt?desc=False")
From the command line:
gem5.opt --stats-file="text://stats.txt?desc=False"
Internally, the stat framework uses the _url_factory decorator
to wrap a Python function with the fn(path, **kwargs) signature in a
function that takes a parsed URL as its only argument. The path and
keyword arguments are automatically derived from the URL in the
wrapper function.
New output formats can be registered in the m5.stats.factories
dictionary. This dictionary contains a mapping between format names
(URL schemes) and factory methods.
To retain backwards compatibility, the code automatically assumes that
the user wants text output if no format has been specified (i.e., when
specifying a plain path).

Python's header files set various compiler macros (e.g.,

that end up being treated as errors. The Python integration manual [1]

The headers declared in export_method_cxx_predecls are redundant since a
SimObject's main header is automatically included.

Some configuration scripts need periodic stat dumps. One of the ways
this can be achieved is by using the pariodicStatDump helper
function. This function was previously only exported in the internal
name space. Export it as a normal function in m5.stat instead.

Ethernet devices are currently only hooked up if running in FS mode. Much of
the Ethernet networking code is generic and can be used to build non-Ethernet
device models. Some of these device models do not require a complex driver
stack and can be built to use an EmulatedDriver in SE mode. This patch enables
etherent interfaces to properly connect regardless of whether the simulation
is in FS or SE mode.

Currently only 'start' and 'end' of AddrRange are printed in config.ini.
This causes address ranges to be overlapping when loading a c++-only
config with interleaved addresses using CxxConfigManger. This patch adds
prints for the interleave and XOR bits to config.ini such that address
ranges are properly setup with cxx config.

This changeset updates the dot output to bail out if it is unable to
resolve the voltage or clock domains (which will cause it to raise an
AttributeError). Additionally, the DVFS dot output is disabled by
default for speed purposes.
Minor fixup for 0aeca8f.

|
This patch adds a secondary dot output file which shows the DVFS domains. This
has been done separately for now to avoid cluttering the already existing
diagram. Due to the way that the clock domains are assigned to components in
gem5, this output must be generated after the C++ objects have been
instantiated. This further motivates the need to generate this file separately
to the current dot output, and not to replace it entirely.

The style refactor change (style: Refactor the style checker as a
Python package) moved region.py from src/python/m5/util/ to
util/style/. The SConscript update accidentally got lost in that
commit. This commit removes region.py from src/python/SConscript.
