This was deprecated in C++14 and removed in C++17. This has been

This operator can be safely brought in scope when needed with "using
stl_helpers::operator<<".
In order to provide a specialization for operator<< with
stl_helpers-enabled types without loosing the hability to use it with
other types, a dual-dispatch mechanism is used. The only entry point
in the system is through a primary dispatch function that won't
resolve for non-helped types. Then, recursive calls go through the
secondary dispatch interface that sort between helped and non-helped
types. Helped typed will enter the system back through the primary
dispatch interface while other types will look for operator<< through
regular lookup, especially ADL.

Currently, gem5 suffers from several bugs related
to Python interpreter's locale encoding issues.
gem5 will crash when the working directory contains
Non-ASCII characters.
The reason is that Python 3.8+ introduces a new
interpreter startup sequence [1]. The startup
sequence consists of three phases:
1. Python core runtime preinitialization
2. Python core runtime initialization
3. Main interpreter configuration
Stage 1 determining the encodings used for system
interfaces.
However, gem5 doesn't preinitialize the Python
interpreter. Thus, the locale settings do not take
effect. This patch preinitialize the Python for
Python 3.8+.
Also, this patch avoid the use of `Py_SetProgramName`,
which is deprecated since Python 3.11[3].

A GUI web-based tool to manage gem5 Resources.
Can manage in two data sources,
a MongoDB database or a JSON file.
The JSON file can be both local or remote.
JSON files are written to a temporary file before
writing to the local file.
The Manager supports the following functions
on a high-level:
- searching for a resource by ID
- navigating to a resource version
- adding a new resource
- adding a new version to a resource
- editing any information within a searched resource
(while enforcing the gem5 Resources schema
found at: https://resources.gem5.org/gem5-resources-schema.json)
- deleting a resource version
- undo and redo up to the last 10 operations
The Manager also allows a user to save a session
through localStorage and re-access it through a password securely.
This patch also provides a
Command Line Interface tool mainly for
MongoDB-related functions.
This CLI tool can currently:
- backup a MongoDB collection to a JSON file
- restore a JSON file to a MongoDB collection
- search for a resource through its ID and
view its JSON object
- make a JSON file that is compliant with the
gem5 Resources Schema

The PCI read/write functions are atomic functions in gem5, meaning they
expect a response with a latency value on the same simulation Tick. For
reads to a PCI device, the response must also include a data value read
from the device.
The AMDGPU device has a PCI BAR which mirrors the frame buffer memory.
Currently reads are done atomically, but writes are sent to a DMA device
without waiting for a write completion ACK. As a result, it is possible
that writes can be queued in the DMA device long enough that another
read for a queued address arrives. This happens very deterministically
with the AtomicSimpleCPU and causes GPUFS to break with that CPU.
This change makes writes to the frame BAR atomic the same as reads. This
avoids that problem and as a result the AtomicSimpleCPU can now load the
driver for GPUFS simulations.

The unconditional exit event when a kernel completes that was added in
c644eae2dd is causing scripts that do not
ignore unknown exit events to end simulation prematurely. One such
script is the apu_se.py script used in SE mode GPU simulation. Make this
exit conditional to the parameter being set to a valid value to avoid
this problem.

Also increase maximum enum supported value to 0x100
This library is courtesy of Daniil Goncharov and hosted at
https://github.com/Neargye/magic_enum/tree/master. It enables
compile-time and runtime string to/from enum value conversion as well
as other fancy enum introspection-like things.
The MIT lincence should not conflict with gem5 in any way.
Copying the file for now but a submodule might be more suitable if
gem5 uses them in the future.

These types include std::pair, std::tuple, all iterable types and any
composition of these. Convenience hash factory and computation
functions are also provided.
These functions are in the stl_helpers namespace and must not move to
::std which could cause undefined behaviour. This is because
specialization of std templates for std or native types (or
composition of these) is undefined behaviour. This inconvenience can't
be circumvented for generic code. Users are free to bring these hash
implementations to namespace std after specialization for their own
non-std and non-native types.

Prior to this patch, when a memory controller was failing at sending a
response to AbstractController, it would not wakeup until the next
request. This patch gives the opportunity to Ruby models to notify
memory response buffer dequeue so that AbstractController can send a
retry request if necessary.
A dequeueMemRspQueue function has been added AbstractController to
automate the dequeue+notify operation.
Note that models that don't notify AbstractController will continue
working as before.

When you build Python from scratch, the modules would be separated
shared libraries. They would be dlopen when doing module import. To make
the separated shared libraries can share the symbol in the binary, we
should add -rdynamic when compliing.
