+
+    Inspired by `gsl::span` and/or `boost::iterator_range`. This class is
+    intended to be used as a parameter type for functions that need to take a
+    writable or read-only sequence of data. Most common cases are `span<char>`
+    and `span<std::uint8_t>`. Using as a class member is only recommended if
+    clearly documented as not doing a deep-copy. C-arrays are easily convertible
+    to this type.
+
+    \note Conversion from C string literal to `span<const char>` will include
+      the NULL-terminator.
+    \note Never allows derived-to-base pointer conversion; an array of derived
+      types is not an array of base types.

+* Some fixes in manpage EXAMPLES and split them into subsections.
+
+
+Version 2.11.1
+--------------
+* Fix bash completions, thanks Tavis Rudd.
+
+

+    Linux 6.9+. Thanks to Honggyu Kim for the patch.
+    - weighted_interleave_membind is added to membind support bits.
+    - The "weighted" policy is added to the hwloc-bind tool.
+  + Add hwloc_obj_set_subtype(). Thanks to Hadrien Grasland for the report.
+* GPU support
+  + Don't hide the GPU NUMA node on NVIDIA Grace Hopper.
+  + Get Intel GPU OpenCL device locality.
+  + Add bandwidths between subdevices in the LevelZero XeLinkBandwidth
+    matrix.
+  + Fix PCI Gen4+ link speed of NVIDIA GPU obtained from NVML,

+  + Fix Windows support when UNICODE is enabled, several hwloc features
+    were missing, thanks to Martin for the report.
+  + Fix the enabling of CUDA in Windows CMake build,
+    Thanks to Moritz Kreutzer for the patch.
+  + Fix CUDA/OpenCL test source path in Windows CMake.
+* Tools
+  + Option --best-memattr may now return multiple nodes. Additional
+    configuration flags may be given to tweak its behavior.
+  + hwloc-info has a new --get-attr option to get a single attribute.
+  + hwloc-info now supports "levels", "support" and "topology"
+    special keywords for backward compatibility for hwloc 3.0.
+  + The --taskset command-line option is superseded by the new
+    --cpuset-output-format which also allows to export as list.
+  + hwloc-calc may now import bitmasks described as a list of bits
+    with the new "--cpuset-input-format list".
+* Misc
+  + The MemoryTiersNr info attribute in the root object now says how many
+    memory tiers were built. Thanks to Antoine Morvan for the report.
+  + Fix the management of infinite cpusets in the bitmap printf/sscanf
+    API as well as in command-line tools.
+  + Add section "Compiling software on top of hwloc's C API" in the
+    documentation with examples for GNU Make and CMake,
+    thanks to Florent Pruvost for the help.
+
+
+Version 2.10.0
+--------------
+* Heterogeneous Memory core improvements
+  + Better heuristics to identify the subtype of memory such as HBM,
+    DRAM, NVM, CXL-DRAM, etc.
+  + Build memory tiers, i.e. sets of NUMA nodes with the same subtype
+    and similar performance.
+    - NUMA node tier ranks are exposed in the new MemoryTier info
+      attribute (starts from 0 for highest bandwidth tier)..
+  + See the new Heterogeneous Memory section in the documentation.
+* API
+  + Add hwloc_topology_free_group_object() to discard a Group created
+    by hwloc_topology_alloc_group_object().
+* Linux backend
+  + Fix cpukinds on NVIDIA Grace to report identical cores even if they
+    actually have very small frequency differences.
+    Thanks to John C. Linford for the report.
+  + Add CXLDevice attributes to CXL DAX objects and NUMA nodes to show
+    which PCI device implements which window.
+  + Ignore buggy memory-side caches and memory attributes when fake NUMA
+    emulation is enabled on the Linux kernel command-line.
+  + Add more info attributes in MemoryModule Misc objects,
+    thanks to Zubiao Xiong for the patch.
+  + Get CPUModel and CPUFamily info attributes on LoongArch platforms.
+* x86 backend
+  + Add support for new AMD CPUID leaf 0x80000026 for better detection
+    of Core Complex and Die on Zen4 processors.
+  + Improve Zhaoxin CPU topology detection.
+* Tools
+  + Input locations and many command-line options (e.g. hwloc-calc -I -N -H,
+    lstopo --only) now accept filters such as "NUMA[HBM]" so that only
+    objects are that type and subtype are considered.
+    - NUMA[tier=1] is also accepted for selecting NUMA nodes depending
+      on their MemoryTier info attribute.
+  + Add --object-output to hwloc-calc to report the type as a prefix to
+    object indexes, e.g. Core:2 instead of 2 in the output of -I.
+  + hwloc-info --ancestor and --descendants now accepts kinds of objects
+    instead of single types.
+    - The new --first option only shows the first matching object.
+  + Add --children-of-pid to hwloc-ps to show a hierarchy of processes.
+    Thanks to Antoine Morvan for the suggestion.
+  + Add --misc-from to lstopo to add Misc objects described in a file.
+    - To be combined with the new hwloc-ps --lstopo-misc for a customizable
+      lstopo --top replacement.
+* Misc
+  + lstopo may now configure the layout of memory object placed above,
+    for instance with --children-order memory:above:vert.
+  + Fix XML import from memory or stdin when using libxml2 2.12.
+  + Fix installation failures when configuring with --target,
+    thanks to Clement Foyer for the patch.
+  + Fix support for 128bit pointer architectures.
+  + Remove Netloc.
+
+
+Version 2.9.3
+-------------
+* Handle Linux glibc allocation errors in binding routines (CVE-2022-47022).
+* Fix hwloc-calc when searching objects on heterogeneous memory platforms,
+  thanks to Antoine Morvan for the report.
+* Fix hwloc_get_next_child() when there are some memory-side caches.
+* Don't crash if the topology is empty because Linux cgroups are wrong.
+* Improve some hwloc-bind warnings in case of command-line parsing errors.
+* Many documentation improvements all over the place, including:
+  + hwloc_topology_restrict() and hwloc_topology_insert_group() may reorder
+    children, causing the logical indexes of objects to change.
+
+
+Version 2.9.2
+-------------
+* Don't forget L3i when defining filters for multiple levels of caches
+  with hwloc_topology_set_cache/icache_types_filter().
+* Fix object total_memory after hwloc_topology_insert_group_object().
+* Fix the (non-yet) exporting in synthetic description for complex memory
+  hierarchies with memory-side caches, etc.
+* Fix some default size attributes when building synthetic topologies.
+* Fix size units in hwloc-annotate.
+* Improve bitmap reallocation error management in many functions.
+* Documentation improvements:
+  + Better document return values of functions.
+  + Add "Error reporting" section (in hwloc.h and in the doxygen doc).
+  + Add FAQ entry "What may I disable to make hwloc faster?"
+  + Improve FAQ entries "Why is lstopo slow?" and
+    "I only need ..., why should I use hwloc?"
+  + Clarify how to deal with cpukinds in hwloc-calc and hwloc-bind
+    manpages.
+
+
+Version 2.9.1
+-------------

+* Tools
+  + Add --grey and --palette options to switch lstopo to greyscale or
+    white-background-only graphics, or to tune individual colors.
+* Build

-Installation
+Since it uses standard Operating System information, hwloc's support is mostly

+Operating System support. The main exception is BSD operating systems (NetBSD,
+FreeBSD, etc.) because they do not provide support topology information, hence
+hwloc uses an x86-only CPUID-based backend (which can be used for other OSes
+too, see the Components and plugins section).

+Programming Interface
+
+The basic interface is available in hwloc.h. Some higher-level functions are
+available in hwloc/helper.h to reduce the need to manually manipulate objects
+and follow links between them. Documentation for all these is provided later in
+this document. Developers may also want to look at hwloc/inlines.h which
+contains the actual inline code of some hwloc.h routines, and at this document,
+which provides good higher-level topology traversal examples.
+
+To precisely define the vocabulary used by hwloc, a Terms and Definitions
+section is available and should probably be read first.
+
+Each hwloc object contains a cpuset describing the list of processing units
+that it contains. These bitmaps may be used for CPU binding and Memory binding.
+hwloc offers an extensive bitmap manipulation interface in hwloc/bitmap.h.
+
+Moreover, hwloc also comes with additional helpers for interoperability with
+several commonly used environments. See the Interoperability With Other
+Software section for details.
+
+The complete API documentation is available in a full set of HTML pages, man
+pages, and self-contained PDF files (formatted for both both US letter and A4
+formats) in the source tarball in doc/doxygen-doc/.
+
+NOTE: If you are building the documentation from a Git clone, you will need to
+have Doxygen and pdflatex installed -- the documentation will be built during
+the normal "make" process. The documentation is installed during "make install"
+to $prefix/share/doc/hwloc/ and your systems default man page tree (under
+$prefix, of course).
+
+Portability
+
+Operating System have varying support for CPU and memory binding, e.g. while
+some Operating Systems provide interfaces for all kinds of CPU and memory
+bindings, some others provide only interfaces for a limited number of kinds of
+CPU and memory binding, and some do not provide any binding interface at all.
+Hwloc's binding functions would then simply return the ENOSYS error (Function
+not implemented), meaning that the underlying Operating System does not provide
+any interface for them. CPU binding and Memory binding provide more information
+on which hwloc binding functions should be preferred because interfaces for
+them are usually available on the supported Operating Systems.
+
+Similarly, the ability of reporting topology information varies from one
+platform to another. As shown in Command-line Examples, hwloc can obtain
+information on a wide variety of hardware topologies. However, some platforms
+and/or operating system versions will only report a subset of this information.
+For example, on an PPC64-based system with 8 cores (each with 2 hardware
+threads) running a default 2.6.18-based kernel from RHEL 5.4, hwloc is only
+able to glean information about NUMA nodes and processor units (PUs). No
+information about caches, packages, or cores is available.
+
+Here's the graphical output from lstopo on this platform when Simultaneous
+Multi-Threading (SMT) is enabled:
+
+[ppc64-with]
+
+And here's the graphical output from lstopo on this platform when SMT is
+disabled:
+
+[ppc64-with]
+
+Notice that hwloc only sees half the PUs when SMT is disabled. PU L#6, for
+example, seems to change location from NUMA node #0 to #1. In reality, no PUs
+"moved" -- they were simply re-numbered when hwloc only saw half as many (see
+also Logical index in Indexes and Sets). Hence, PU L#6 in the SMT-disabled
+picture probably corresponds to PU L#12 in the SMT-enabled picture.
+
+This same "PUs have disappeared" effect can be seen on other platforms -- even
+platforms / OSs that provide much more information than the above PPC64 system.
+This is an unfortunate side-effect of how operating systems report information
+to hwloc.
+
+Note that upgrading the Linux kernel on the same PPC64 system mentioned above
+to 2.6.34, hwloc is able to discover all the topology information. The
+following picture shows the entire topology layout when SMT is enabled:
+
+[ppc64-full]
+
+Developers using the hwloc API or XML output for portable applications should
+therefore be extremely careful to not make any assumptions about the structure
+of data that is returned. For example, per the above reported PPC topology, it
+is not safe to assume that PUs will always be descendants of cores.
+
+Additionally, future hardware may insert new topology elements that are not
+available in this version of hwloc. Long-lived applications that are meant to
+span multiple different hardware platforms should also be careful about making
+structure assumptions. For example, a new element may someday exist between a
+core and a PU.

+History / Credits
+
+hwloc is the evolution and merger of the libtopology project and the Portable
+Linux Processor Affinity (PLPA) (https://www.open-mpi.org/projects/plpa/)
+project. Because of functional and ideological overlap, these two code bases
+and ideas were merged and released under the name "hwloc" as an Open MPI
+sub-project.
+
+libtopology was initially developed by the Inria Runtime Team-Project. PLPA was
+initially developed by the Open MPI development team as a sub-project. Both are
+now deprecated in favor of hwloc, which is distributed as an Open MPI
+sub-project.
