 0.9.


+Version 2.12.1
+--------------
+* Add hwloc-calc's --default-nodes option to hwloc-bind and hwloc-info.
+* Improve the --best-memattr "default" fallback, try to use "default"
+  memory nodes, and add verbose messages and warnings if some
+  performance info are incomplete or missing.
+  Thanks to Antoine Morvan for the report.
+* Fix CPU and memory binding on different locations,
+  thanks to Antoine Morvan for the report.
+* Add HWLOC_LOCAL_NUMANODE_FLAG_INTERSECT_LOCALITY and enable it by
+  default in hwloc-calc --local-memory for finding local NUMA nodes
+  that do not exactly match input locations.
+  Thanks to Antoine Morvan for the report.
+* Fix a possible crash in the x86 backend when Qemu is configured to
+  expose multicore/thread CPUs that are actually single-core/thread.
+  Thanks to Georg Pfuetzenreuter.
+
+
+Version 2.12.0
+--------------
+* Add hwloc_topology_get_default_nodeset() for the set of default
+  NUMA nodes.
+  - hwloc-calc now has --default-nodes option.
+* Rework oneAPI LevelZero support to use zesInit() and avoid the need
+  to set ZES_ENABLE_SYSMAN=1 in the environment.
+  - zesDriverGetDeviceByUuidExp() is now required in the L0 runtime.
+  - ZES/Sysman variants were added in hwloc/levelzero.h to specifically
+    handle ZES/Sysman device handles.
+* Fix the locality of AMD GPU partitions, thanks to Edgar Leon for
+  reporting and debugging the issue.
+* Better detect Cray Slingshot NICs, thanks to Edgar Leon.
+* Add support for Die objects and Module groups on Windows.
+* Only filter-out Dies that are identical to their Packages
+  when it applies to all Dies.
+* Improve hwloc-calc to handle CPU-less NUMA nodes or platforms with
+  heterogeneous memory without requiring --nodeset-output.
+* hwloc-calc now accepts counting/listing cpukinds and memory tiers
+  with -N and -I cpukind/memorytier.
+* The systemd-dbus-api output of hwloc-calc has changed, and
+  --nodeset-output-format was added, to support NUMA node outputs.
+  Thanks to Pierre Neyron.
+* Update NVLink bandwidth and CUDA capabilities up to NVIDIA Blackwell.
+* Fix some NUMA syscalls on Linux for platforms with old libc headers.
+* Some minor fixes in distances.
+
+
 Version 2.11.2
 --------------
 * Add missing CPU info attrs on aarch64 on Linux.

+ * These are usually DRAM nodes.
+ *
+ * Other nodes may be reserved for specific use (I/O device memory, e.g. GPU memory),
+ * small but high performance (HBM), large but slow memory (NVM), etc.
+ * Buffers should usually not be allocated from there unless explicitly required.
+ *
+ * This function fills \p nodeset with the bits of NUMA nodes considered default.
+ *
+ * It is guaranteed that these nodes have non-intersecting CPU sets,
+ * i.e. cores may not have multiple local NUMA nodes anymore.
+ * Hence this may be used to iterate over the platform divided into separate
+ * NUMA localities, for instance for binding one task per NUMA domain.
+ *
+ * Any core that had some local NUMA node(s) in the initial topology should
+ * still have one in the default nodeset. Corner cases where this would be
+ * wrong consist in asymmetric platforms with missing DRAM nodes, or topologies
+ * that were already restricted to less NUMA nodes.
+ *
+ * The returned nodeset may be passed to hwloc_topology_restrict() with
+ * ::HWLOC_RESTRICT_FLAG_BYNODESET to remove all non-default nodes from
+ * the topology. The resulting topology will be easier to use when iterating
+ * over (now homogeneous) NUMA nodes.
+ *
+ * The heuristics for finding default nodes relies on memory tiers and subtypes
+ * (see \ref heteromem) as well as the assumption that hardware vendors list
+ * default nodes first in hardware tables.
+ *

+ * returned by hwloc_topology_get_topology_nodeset(). It is strictly smaller
+ * if the machine has heterogeneous memory.

- * Define ZES_ENABLE_SYSMAN=1 early so that the LevelZero backend gets Sysman enabled.
- *
- * Only if the levelzero was enabled in this build so that we don't enable sysman
- * for external levelzero users when hwloc doesn't need it. If somebody ever loads
- * an external levelzero plugin in a hwloc library built without levelzero (unlikely),
- * he may have to manually set ZES_ENABLE_SYSMAN=1.
- *
- * Use the constructor if supported and/or the Windows DllMain callback.
- * Do it in the main hwloc library instead of the levelzero component because
- * the latter could be loaded later as a plugin.
- *
- * L0 seems to be using getenv() to check this variable on Windows
- * (at least in the Intel Compute-Runtime of March 2021),
- * but setenv() doesn't seem to exist on Windows, hence use putenv() to set the variable.
- *
- * For the record, Get/SetEnvironmentVariable() is not exactly the same as getenv/putenv():
- * - getenv() doesn't see what was set with SetEnvironmentVariable()
- * - GetEnvironmentVariable() doesn't see putenv() in cygwin (while it does in MSVC and MinGW).
- * Hence, if L0 ever switches from getenv() to GetEnvironmentVariable(),
- * it will break in cygwin, we'll have to use both putenv() and SetEnvironmentVariable().
- * Hopefully L0 will provide a way to enable Sysman without env vars before it happens.
