hwloc

USE flags

• abi_mips_n32 - 64-bit (32-bit pointer) libraries
• abi_mips_n64 - 64-bit libraries
• abi_mips_o32 - 32-bit libraries
• abi_s390_32 - 32-bit (s390) libraries
• abi_s390_64 - 64-bit (s390x) libraries
• abi_x86_32 - 32-bit (x86) libraries
• abi_x86_64 - 64-bit (amd64) libraries
• abi_x86_x32 - x32 ABI libraries
• cairo - Enable the Cairo back-end of hwloc's lstopo command
• cpuid - Enable the cpuid-based architecture specific support (x86 component)
• cuda - Enable CUDA device discovery using libcudart
• debug - Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces
• gl - Enable GL display device discovery (NVCtrl)
• numa - Add support for numa memory allocation
• nvml - Enable the NVML device discovery
• pci - Enable PCI device discovery using libpci
• plugins - Build hwloc components as plugins so that the hwloc core library does not directly depend on their dependencies (for instance the libpci library)
• static-libs - Build static versions of dynamic libraries as well
• svg - Add support for SVG (Scalable Vector Graphics)
• udev - Enable virtual/udev integration (device discovery, power and storage device support, etc)
• valgrind - Enable annotations for accuracy. May slow down runtime slightly. Safe to use even if not currently using dev-util/valgrind
• video_cards_nvidia - VIDEO_CARDS setting to build driver for nvidia video cards
• X - use the X Window System
• xml - use libxml2 for XML support, instead of a custom minimalistic support
