      + Fix the detection of the memory-side cache:
    - Add the hwloc-dump-hwdata superuser utility to dump SMBIOS
      into /var/run/hwloc/ as root during boot, and load this dumped
      information from the hwloc library at runtime.
    - See "Why do I need hwloc-dump-hwdata for caches on Intel Knights
      Landing Xeon Phi?" in the documentation.
      Thanks to Grzegorz Andrejczuk for the patches and for the help.
    * The x86 and linux backends may now be combined for discovering CPUs
      through x86 CPUID and memory from the Linux kernel.
      This is useful for working around buggy CPU information reported by Linux
      (for instance the AMD Bulldozer/Piledriver bug below).
      Combination is enabled by passing HWLOC_COMPONENTS=x86 in the environment.

      it discovers, or to caches discovered by other backends earlier.
      Thanks to Guillaume Beauchamp for the patch.
    * Fix the management on alloc_membind() allocation failures on AIX, HP-UX
      and OSF/Tru64.
    * Fix spurious failures to load with ENOMEM on AIX in case of Misc objects
      below PUs.
    * lstopo improvements in X11 and Windows graphical mode:
      + Add + - f 1 shortcuts to manually zoom-in, zoom-out, reset the scale,
      or fit the entire window.
      + Display all keyboard shortcuts in the console.
    * Debug messages may be disabled at runtime by passing
      in the environment when --enable-debug was passed to configure.
    * Add a FAQ entry "What are these Group objects in my topology?".
* Mon Nov 16 2015
  - Update to version 1.11.1

      in the x86 backend.
    * Detect block devices directly attached to PCI without a controller,
      for instance NVMe disks.
    * Add the PCISlot attribute to all PCI functions instead of only the
      first one.
    * Ignore PCI bridges that could fail assertions by reporting buggy
      secondary-subordinate bus numbers
    * Fix an overzealous assertion when inserting an intermediate Group object
      while Groups are totally ignored.

  - Update to 1.10.1
    * Actually remove disallowed NUMA nodes from nodesets when the
      whole-system flag isn't enabled.
    * Fix the gathering of PCI domains. Thanks to James Custer for
      reporting the issue and providing a patch.

    * Change hwloc-ls.desktop into a lstopo.desktop and only install
      it if lstopo is built with Cairo/X11 support. It cannot work
      with a non-graphical lstopo or hwloc-ls.
    * Add support for the renaming of Socket into Package in
      future releases.
    * Add support for the replacement of HWLOC_OBJ_NODE with
      HWLOC_OBJ_NUMANODE in future releases.
    * Clarify the documentation of distance matrices in hwloc.h and

      the suggestion.
    * Improve some error messages by displaying more information
      about the hwloc library in use.
    * Document how to deal with the ABI break when upgrading to
      the upcoming 2.0 See "How do I handle ABI breaks and API
      upgrades ?" in the FAQ.
* Tue Dec 30 2014
  - minor spec fixes (unbreak build for suse_version < Factory)
* Tue Dec 16 2014
  - Update to Version 1.10.0
    * v1.10.0 is the new feature release. There is no new major change
      in this release, just improvements everywhere.
      If you are buying new Intel Xeon E5 with 10 cores or more, this
      release is required for proper Socket/NUMA detection until the
      Linux kernel gets fixed.
    * API
      + Add hwloc_topology_export_synthetic() to export a topology to a
      synthetic string without using lstopo. See the Synthetic topologies
      section in the documentation.
      + Add hwloc_topology_set/get_userdata() to let the application save
      a private pointer in the topology whenever it needs a way to find
      its own object corresponding to a topology.
      + Add hwloc_get_numanode_obj_by_os_index() and document that this function
      as well as hwloc_get_pu_obj_by_os_index() are good at converting
      nodesets and cpusets into objects.
      + hwloc_distrib() does not ignore any objects anymore when there are
      too many of them. They get merged with others instead.
      Thanks to Tim Creech for reporting the issue.
    * Tools
      + hwloc-bind --get <command-line> now executes the command after displaying
      the binding instead of ignoring the command entirely.
      Thanks to John Donners for the suggestion.
      + Clarify that memory sizes shown in lstopo are local by default
      unless specified (total memory added in the root object).
    * Synthetic topologies
      + Synthetic topology descriptions may now specify attributes such as
      memory sizes and OS indexes. See the Synthetic topologies section
      in the documentation.
      + lstopo now exports in this fully-detailed format by default.
      The new option --export-synthetic-flags may be used to revert
      back the old format.
    * Documentation
      + Add the doc/examples/ subdirectory with several real-life examples,
      including the already existing hwloc-hello.C for basics.
      Thanks to Rob Aulwes for the suggestion.
      + Improve the documentation of CPU and memory binding in the API.
      + Add a FAQ entry about operating system errors, especially on AMD
      platforms with buggy cache information.
      + Add a FAQ entry about loading many topologies in a single program.
    * Misc
      + Work around buggy Linux kernels reporting 2 sockets instead
      1 socket with 2 NUMA nodes for each Xeon E5 v3 (Haswell) processor.
      + pciutils/libpci support is now removed since libpciaccess works
      well and there's also a Linux-specific PCI backend. For the record,
      pciutils was GPL and therefore disabled by default since v1.6.2.
      + Add --disable-cpuid configure flag to work around buggy processor
      simulators reporting invalid CPUID information.
      Thanks for Andrew Friedley for reporting the issue.
      + Fix a racy use of libltdl when manipulating multiple topologies in
      different threads.
      Thanks to Andra Hugo for reporting the issue and testing patches.
      + Fix some build failures in private/misc.h.
      Thanks to Pavan Balaji and Ralph Castain for the reports.
      + Fix failures to detect X11/Xutil.h on some Solaris platforms.
      Thanks to Siegmar Gross for reporting the failure.
      + The plugin ABI has changed, this release will not load plugins
      built against previous hwloc releases.
* Sun Aug 17 2014
  - removed patches (fixed upstream)
    * hwloc-1.7-manpage.patch
    * hwloc-1.7.patch
  - Update to Version 1.9.0
    * API
      + Add hwloc_obj_type_sscanf() to extend hwloc_obj_type_of_string() with
      type-specific attributes such as Cache/Group depth and Cache type.
      hwloc_obj_type_of_string() is moved to hwloc/deprecated.h.
      + Add hwloc_linux_get_tid_last_cpu_location() for retrieving the
      last CPU where a Linux thread given by TID ran.
      + Add hwloc_distrib() to extend the old hwloc_distribute[v]() functions.
      hwloc_distribute[v]() is moved to hwloc/deprecated.h.
      + Don't mix total and local memory when displaying verbose object attributes
      with hwloc_obj_attr_snprintf() or in lstopo.
    * Backends
      + Add CPUVendor, CPUModelNumber and CPUFamilyNumber info attributes for
      x86, ia64 and Xeon Phi sockets on Linux, to extend the x86-specific
      support added in v1.8.1. Requested by Ralph Castain.
      + Add many CPU- and Platform-related info attributes on ARM and POWER
      platforms, in the Machine and Socket objects.
      + Add CUDA info attributes describing the number of multiprocessors and
      cores and the size of the global, shared and L2 cache memories in CUDA
      OS devices.
      + Add OpenCL info attributes describing the number of compute units and
      the global memory size in OpenCL OS devices.
      + The synthetic backend now accepts extended types such as L2Cache, L1i or
      Group3. lstopo also exports synthetic strings using these extended types.
    * Tools
      + lstopo
    - Do not overwrite output files by default anymore.
      Pass -f or --force to enforce it.
    - Display OpenCL, CUDA and Xeon Phi numbers of cores and memory sizes
      in the graphical output.
    - Fix export to stdout when specifying a Cairo-based output type
      with --of.
      + hwloc-ps
    - Add -e or --get-last-cpu-location to report where processes/threads
      run instead of where they are bound.
    - Report locations as likely-more-useful objects such as Cores or Sockets
      instead of Caches when possible.
      + hwloc-bind
    - Fix failure on Windows when not using --pid.
    - Add -e as a synonym to --get-last-cpu-location.
      + hwloc-distrib
    - Add --reverse to distribute using last objects first and singlify
      into last bits first. Thanks to Jirka Hladky for the suggestion.
      + hwloc-info
    - Report unified caches when looking for data or instruction cache
      ancestor objects.
    * Misc
      + Add experimental Visual Studio support under contrib/windows.
      Thanks to Eloi Gaudry for his help and for providing the first draft.
      + Fix some overzealous assertions and warnings about the ordering of
      objects on a level with respect to cpusets. The ordering is only
      guaranteed for complete cpusets (based on the first bit in sets).
      + Fix some memory leaks when importing xml diffs and when exporting a
      "too complex" entry.
    * Fix the cpuid code on Windows 64bits so that the x86 backend gets
      enabled as expected and can populate CPU information.
      Thanks to Robin Scher for reporting the problem.
    * Add CPUVendor/CPUModelNumber/CPUFamilyNumber attributes when running
      on x86 architecture. Thanks to Ralph Castain for the suggestion.
    * Work around buggy BIOS reporting duplicate NUMA nodes on Linux.
      Thanks to Jeff Becker for reporting the problem and testing the patch.
    * Add a name to the lstopo graphical window. Thanks to Michael Prokop
      for reporting the issue.
    * New components
      + Add the "linuxpci" component that always works on Linux even when
      libpciaccess and libpci aren't available (and even with a modified
      file-system root). By default the old "pci" component runs first
      because "linuxpci" lacks device names (obj->name is always NULL).
    * API
      + Add the topology difference API in hwloc/diff.h for manipulating
      many similar topologies.
      + Add hwloc_topology_dup() for duplicating an entire topology.
      + hwloc.h and hwloc/helper.h have been reorganized to clarify the
      documentation sections. The actual inline code has moved out of hwloc.h
      into the new hwloc/inlines.h.
      + Deprecated functions are now in hwloc/deprecated.h, and not in the
      official documentation anymore.
    * Tools
      + Add hwloc-diff and hwloc-patch tools together with the new diff API.
      + Add hwloc-compress-dir to (de)compress an entire directory of XML files
      using hwloc-diff and hwloc-patch.
      + Object colors in the graphical output of lstopo may be changed by adding
      a "lstopoStyle" info attribute. See CUSTOM COLORS in the lstopo(1) manpage
      for details. Thanks to Jirka Hladky for discussing the idea.
      + hwloc-gather-topology may now gather I/O-related files on Linux when
    - -io is given. Only the linuxpci component supports discovering I/O
      objects from these extended tarballs.
      + hwloc-annotate now supports --ri to remove/replace info attributes with
      a given name.
      + hwloc-info supports "root" and "all" special locations for dumping
      information about the root object.
      + lstopo now supports --append-legend to append custom lines of text
      to the legend in the graphical output. Thanks to Jirka Hladky for
      discussing the idea.
      + hwloc-calc and friends have a more robust parsing of locations given
      on the command-line and they report useful error messages about it.
      + Add --whole-system to hwloc-bind, hwloc-calc, hwloc-distances and
      hwloc-distrib, and add --restrict to hwloc-bind for uniformity among
    * Misc
      + Calling hwloc_topology_load() or hwloc_topology_set_*() on an already
      loaded topology now returns an error (deprecated since release 1.6.1).
      + Fix the initialisation of cpusets and nodesets in Group objects added
      when inserting PCI hostbridges.
      + Never merge Group objects that were added explicitly by the user with
      + Add a sanity check during dynamic plugin loading to prevent some
      crashes when hwloc is dynamically loaded by another plugin mechanisms.
      + Add --with-hwloc-plugins-path to specify the install/load directories
      of plugins.
      + Add the MICSerialNumber info attribute to the root object when running
      hwloc inside a Xeon Phi to match the same attribute in the MIC OS device
      when running in the host.
    * Do not create invalid block OS devices on very old Linux kernel such
      as RHEL4 2.6.9.
    * Fix PCI subvendor/device IDs.
    * Fix the management of Misc objects inserted by parent.
      Thanks to Jirka Hladky for reporting the problem.
    * Add a Port<n>State into attribute to OpenFabrics OS devices.
    * Add a MICSerialNumber info attribute to Xeon PHI/MIC OS devices.
    * Improve verbose error messages when failing to load from XML.
    * Fix a failed assertion in the distance grouping code when loading a XML
      file that already contains some groups.
      Thanks to Laercio Lima Pilla for reporting the problem.
    * Remove unexpected Group objects when loading XML topologies with I/O
      objects and NUMA distances.

      would contradict the existing hierarchy
    * grouping by distances now also works when loading from XML
    * fix some corner cases in object insertion, for instance when dealing with
      NUMA nodes without any CPU
    * implement hwloc_get_area_membind() on Linux
    * honor I/O topology flags when importing from XML
    * further improve XML-related error checking and reporting
    * hide synthetic topology error messages unless HWLOC_SYNTHETIC_VERBOSE=1
    * add synthetic exporting of symmetric topologies to lstopo
    * lstopo --horiz and --vert can now be applied to some specific object types
    * lstopo -v -p now displays distance matrices with physical indexes
    * add hwloc-distances utility to list distances
    * fix and/or document the behavior of most inline functions in hwloc/helper.h
      when the topology contains some I/O or Misc objects
    * backend documentation enhancements
    * fix dependencies in the embedded library
    * remove references to internal symbols in the tools
  - changes from 1.3.2:
    * fix missing last bit in hwloc_linux_get_thread_cpubind()
    * fix PCI locality when Linux cgroups restrict the available CPUs
    * fix conversion from/to Linux libnuma when some NUMA nodes have no memory
    * remove references to internal symbols in the tools
    * further improve XML-related error checking and reporting
* Wed Dec 21 2011
  - update to 1.3.1:
    * silence some harmless pciutils warnings
  - changes from 1.3.0:
    * add I/O devices and bridges to the topology using the pciutils library;
      only enabled after setting the relevant flag with
      hwloc_topology_set_flags() before hwloc_topology_load(). See the I/O
      Devices section in the documentation for details.
    * discovery improvements:
      + add associativity to the cache attributes
      + add support for s390/z11 "books" on Linux
      + add the HWLOC_GROUPING_ACCURACY environment variable to relax
      distance-based grouping constraints. See the Environment Variables
      section in the documentation for details about grouping behavior and
      + allow user-given distance matrices to remove or replace those discovered
      by the OS backend
    * XML improvements:
      + XML is now always supported: a minimalistic custom import/export code is
      used when libxml2 is not available. It is only guaranteed to read XML
      files generated by hwloc.
      + hwloc_topology_export_xml() and export_xmlbuffer() now return an integer
      + add hwloc_free_xmlbuffer() to free the buffer allocated by
      + hide XML topology error messages unless HWLOC_XML_VERBOSE=1
    * minor API updates:
      + add hwloc_obj_add_info to customize object info attributes
    * tools:
      + lstopo now displays I/O devices by default. Several options are added to
      configure the I/O discovery.
      + hwloc-calc and hwloc-bind now accept I/O devices as input
      + add --restrict option to hwloc-calc and hwloc-distribute
      + add --sep option to change the output field separator in hwloc-calc
      + add --whole-system option to hwloc-ps
  - changes from 1.2.2:
    * fix XML import of very large page sizes or counts on 32bits platform
    * fix crash when administrator limitations such as Linux cgroup require to
      restrict distance matrices
    * fix the removal of objects such as AMD Magny-Cours dual-node sockets in
      case of administrator restrictions
    * improve error reporting and messages in case of wrong synthetic topology
* Fri Aug 26 2011
  - update to 1.2.1:
    * improve support of AMD Bulldozer "Compute-Unit" modules by detecting
      logical processors with different core IDs on Linux
    * fix hwloc-ps crash when listing processes from another Linux cpuset
    * fix hwloc_get_last_cpu_location(THREAD) on Linux
* Wed Jun 01 2011
  - initial version (1.2)
