- minor spec fixes (unbreak build for suse_version < Factory)

Tue Dec 16 09:22:26 UTC 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 18:42:36 UTC 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.
    Thanks to Elena Elkina for reporting the problem and testing patches.
  * Fix PCI link speed discovery when using libpciaccess.
  * Fix invalid libpciaccess virtual function device/vendor IDs when using
    SR-IOV PCI devices on Linux.
  * Fix GL component build with old NVCtrl releases.
    Thanks to Jirka Hladky for reporting the problem.
  * Fix embedding breakage caused by libltdl.
    Thanks to Pavan Balaji for reporting the problem.
  * Always use the system-wide libltdl instead of shipping one inside hwloc.
  * Document issues when enabling plugins while embedding hwloc in another
    project, in the documentation section Embedding hwloc in Other Software.
  * Add a FAQ entry "How to get useful topology information on NetBSD?"
    in the documentation.
  * Somes fixes in the renaming code for embedding.
  * Miscellaneous minor build fixes.
