+ hwloc-info now supports "levels", "support" and "topology"
special keywords for backward compatibility for hwloc 3.0.

- update to 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).
+ Add hwloc_topology_free_group_object() to discard a Group
created by hwloc_topology_alloc_group_object().
+ Fix cpukinds on NVIDIA Grace to report identical cores
even if they actually have very small frequency differences.
+ 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,
+ Get CPUModel and CPUFamily info attributes on LoongArch
platforms.
+ Add support for new AMD CPUID leaf 0x80000026 for better
detection of Core Complex and Die on Zen4 processors.
+ Improve Zhaoxin CPU topology detection.
+ 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.

in a file.
- To be combined with the new hwloc-ps --lstopo-misc for
a customizable lstopo --top replacement.
* Wed Oct 18 2023 Dominique Leuenberger <dimstar@opensuse.org>
- Update to 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,
* 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.
* Sun Jul 16 2023 Dirk Müller <dmueller@suse.com>
- update to 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
* Tue Jun 20 2023 Dirk Müller <dmueller@suse.com>
- update to 2.9.1:
* Fix a failed assertion in hwloc_topology_restrict() when some
NUMA nodes are removed because of
HWLOC_RESTRICT_FLAG_REMOVE_CPULESS but no PUs are.
* Mark HPE Cray Slingshot NICs with subtype "Slingshot".
* Tue Jun 06 2023 Egbert Eich <eich@suse.com>
- Readd libXNVCtrl support as an optional plugin.
- Add OpenCL support as an optional plugin.
- Ship GUI tool in a separate package. This avoids installing
undesirable X11 dependencies.
* Tue May 09 2023 Thomas Blume <thomas.blume@suse.com>
- remove header files for feature we don't ship (jsc#PED-4156)
These headers do not define an API that is not supported at present and
therefore would not cause a failure during build. Still, they define static
inline functions which look for HWLOC objects that are only set up by
non-supported device scanners. Thus these objects will never be present - even
though the relevant hardware is.
* Thu Jan 26 2023 Callum Farmer <gmbr3@opensuse.org>
- Remove libXNVCtrl support as it brings too many X dependencies
(bsc#1207545)
* Fri Dec 23 2022 Dirk Müller <dmueller@suse.com>
- update to 2.9.0:
+ Expose the memory size of CXL memory devices (Type 3) on Linux.
+ The LevelZero backend now reports the "XeLinkBandwidth" distance
matrix between L0 devices (and subdevices) when available.
+ Add support for CUDA compute capability up to 9.0.
+ lstopo now switches to console mode when its output is redirected.
Graphical window mode may be forced back with --of window.
+ hwloc-calc now accepts "numa" in -H, and I/O subtypes such as "gpu"
in -I and -N.
* Fri Jul 29 2022 Callum Farmer <gmbr3@opensuse.org>
- Add libXNVCtrl support on TW
* Mon Jul 11 2022 Dirk Müller <dmueller@suse.com>
- update to 2.8.0:
* API
+ Add HWLOC_TOPOLOGY_FLAG_NO_DISTANCES, _NO_MEMATTRS and _NO_CPUKINDS
to reduce the overhead when unneeded.
+ Add separate Read/Write Bandwidth/Latency memory attributes and
implement them on Linux.
* Backends
+ NUMA nodes may now have a subtype such as DRAM, HBM, SPM, or NVM
on heterogeneous memory platforms on Linux.
- Add DAXType and DAXParent attributes on Linux to tell where a
DAX device or its corresponding NUMA node come from (SPM for
Specific-Purpose or NVM for Non-Volatile Memory).
+ Detect heterogeneous caches in hybrid CPUs on MacOS X,
thanks to Paul Bone for the help.
+ Max frequencies are not ignored in Linux cpukinds anymore (they were
ignored in hwloc 2.7.0), but they may be slightly adjusted to avoid
reporting hybrid CPUs because Intel Turbo Boost Max 3.0.
- See the documentation of environment variable HWLOC_CPUKINDS_MAXFREQ.
+ Hardwire the PCI locality of HPE Cray EX235a nodes.
* Tools
+ lstopo and other tools may now load Linux and x86 cpuid topology files
from a tarball.
+ lstopo may now replace the P# and L# index prefixes with custom strings
thanks to --os-index-prefix and --logical-index-prefix options.
* Misc
+ Add --disable-readme to avoid regenerating the top-level hwloc README
file from the documentation.
* Bugfix
+ Use setenv() instead of putenv() - fixes crash in Slurm (bsc#1210227)
* Fri Apr 08 2022 Dirk Müller <dmueller@suse.com>
- update to 2.7.1:
* Workaround crashes when virtual machines report incoherent x86 CPUID
information about numbers of cores and threads.
Thanks to Peter Bense for the report.
* Use setenv() instead of putenv() when trying to force enable oneAPI L0
support, to avoid issues with applications that touch the environment,
thanks to Josh Hursey for the patch.
* Add some warnings at the end of configure when GPU libraries are
missing on the system or their path is missing in the environment.
* Backends
+ Add support for NUMA nodes and caches with more than 64 PUs across
multiple processor groups on Windows 11 and Windows Server 2022.
+ Group objects are not created for Windows processor groups anymore,
except if HWLOC_WINDOWS_PROCESSOR_GROUP_OBJS=1 in the environment.
+ Expose "Cluster" group objects on Linux kernel 5.16+ for CPUs
that share some internal cache or bus. This can be equivalent
to the L2 Cache level on some platforms (e.g. x86) or a specific
level between L2 and L3 on others (e.g. ARM Kungpeng 920).
Thanks to Jonathan Cameron for the help.
- HWLOC_DONT_MERGE_CLUSTER_GROUPS=1 may be set in the environment
to prevent these groups from being merged with identical caches, etc.
+ Improve the oneAPI LevelZero backend:
- Expose subdevices such as "ze0.1" inside root OS devices ("ze0")
when the hardware contains multiple subdevices.
- Add many new attributes to describe device type, and the
numbers of slices, subslices, execution units and threads.
- Expose the memory information as LevelZeroHBM/DDR/MemorySize infos.
+ Ignore the max frequencies of cores in Linux cpukinds when the
base frequencies are available (to avoid exposing hybrid CPUs
when Intel Turbo Boost Max 3.0 gives slightly different max
frequencies to CPU cores).
- May be reverted by setting HWLOC_CPUKINDS_MAXFREQ=1 in the environment.
* Tools
+ Add --grey and --palette options to switch lstopo to greyscale or
white-background-only graphics, or to tune individual colors.
* Build
+ Windows CMake builds now support non-MSVC compilers, detect several
features at build time, can build/run tests, etc.
Thanks to Michael Hirsch and Alexander Neumann .
