qemudCapsInitNUMA and umlCapsInitNUMA were identical, so this change factors them into a new function, virCapsInitNUMA, and puts it in nodeinfo.c. In addition to factoring out the duplicates, this change also adjusts that function definition (along with its macros) so that it works with Fedora 9's numactl version 1, and makes it so the code will work even if someone builds the kernel with CONFIG_NR_CPUS > 4096. Finally, also perform this NUMA initialization for the lxc and openvz drivers. * src/nodeinfo.c: Include <stdint.h>, <numa.h> and "memory.h". (virCapsInitNUMA): Rename from qemudCapsInitNUMA and umlCapsInitNUMA. (NUMA_MAX_N_CPUS): Define depending on NUMA API version. (n_bits, MASK_CPU_ISSET): Define, adjust, use uint64 rather than long. * src/nodeinfo.h: Include "capabilities.h". (virCapsInitNUMA): Declare it. * examples/domain-events/events-c/Makefile.am: * src/Makefile.am: Add $(NUMACTL_CFLAGS) and $(NUMACTL_LIBS) to various compile/link-related variables. * src/qemu_conf.c: Include "nodeinfo.h". (qemudCapsInitNUMA): Remove duplicate code. Adjust caller. * src/uml_conf.c (umlCapsInitNUMA): Likewise. Include "nodeinfo.h". * src/lxc_conf.c: Include "nodeinfo.h". (lxcCapsInit): Perform NUMA initialization here, too. * src/openvz_conf.c (openvzCapsInit): And here. Include "nodeinfo.h". * src/libvirt_sym.version.in: Add virCapsInitNUMA so that libvirtd can link to this function.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
