Version 1.11.0

• API
• Socket objects are renamed into Package to align with the terminology used by processor vendors. The old HWLOC_OBJ_SOCKET type and "Socket" name are still supported for backward compatibility.
• HWLOC_OBJ_NODE is replaced with HWLOC_OBJ_NUMANODE for clarification. HWLOC_OBJ_NODE is still supported for backward compatibility. "Node" and "NUMANode" strings are supported as in earlier releases.
• Detection improvements
• Add support for Intel Knights Landing Xeon Phi. Thanks to Grzegorz Andrejczuk and Lukasz Anaczkowski.
• Add Vendor, Model, Revision, SerialNumber, Type and LinuxDeviceID info attributes to Block OS devices on Linux. Thanks to Vineet Pedaballe for the help.
• Add "MemoryDevice" Misc objects with information about DIMMs, on Linux when privileged and when I/O is enabled. Thanks to Vineet Pedaballe for the help.
• Add a PCISlot attribute to PCI devices on Linux when supported to identify the physical PCI slot where the board is plugged.
• Add CPUStepping info attribute on x86 processors, thanks to Thomas Röhl for the suggestion.
• Ignore the device-tree on non-Power architectures to avoid buggy detection on ARM. Thanks to Orion Poplawski for reporting the issue.
• Work-around buggy Xeon E5v3 BIOS reporting invalid PCI-NUMA affinity for the PCI links on the second processor.
• Add support for CUDA compute capability 5.x, thanks Benjamin Worpitz.
• Many fixes to the x86 backend
  • Add L1i and fix L2/L3 type on old AMD processors without topoext support.
  • Fix Intel CPU family and model numbers when basic family isn't 6 or 15.
  • Fix package IDs on recent AMD processors.
  • Fix misc issues due to incomplete APIC IDs on x2APIC processors.
  • Avoid buggy discovery on old SGI Altix UVs with non-unique APIC IDs.
• Gather total machine memory on NetBSD.
• Tools
• lstopo
  • Collapse identical PCI devices unless --no-collapse is given. This avoids gigantic outputs when a PCI device contains dozens of identical virtual functions.
  • The ASCII art output is now called "ascii", for instance in "lstopo -.ascii". The former "txt" extension is retained for backward compatibility.
  • Automatically scales graphical box width to the inner text in Cairo, ASCII and Windows outputs.
  • Add --rect to lstopo to force rectangular layout even for NUMA nodes.
  • Add --restrict-flags to configure the behavior of --restrict.
  • Objects may have a "Type" info attribute to specify a better type name and display it in lstopo.
  • Really export all verbose information to the given output file.
• hwloc-annotate
  • May now operate on all types of objects, including I/O.
  • May now insert Misc objects in the topology.
  • Do not drop instruction caches and I/O devices from the output anymore.
• Fix lstopo path in hwloc-gather-topology after install.
• Misc
• Fix hwloc/cudart.h for machines with multiple PCI domains, thanks to Imre Kerr for reporting the problem.
• Fix PCI Bridge-specific depth attribute.
• Fix hwloc_bitmap_intersect() for two infinite bitmaps.
• Fix some corner cases in the building of levels on large NUMA machines with non-uniform NUMA groups and I/Os.
• Improve the performance of object insertion by cpuset for large topologies.
• Prefix verbose XML import errors with the source name.
• Improve pkg-config checks and error messages.
• Fix excluding after a component with an argument in the HWLOC_COMPONENTS environment variable.
• Documentation
• Fix the recommended way in documentation and examples to allocate memory on some node, it should use HWLOC_MEMBIND_BIND. Thanks to Nicolas Bouzat for reporting the issue.
• Add a "Miscellaneous objects" section in the documentation.
• Add a FAQ entry "What happens to my topology if I disable symmetric multithreading, hyper-threading, etc. ?" to the documentation.
