Michal Privoznik (7): configure: Check for statfs Introduce virFileFindHugeTLBFS qemu: Utilize virFileFindHugeTLBFS virbitmap: Introduce virBitmapDoesIntersect domain: Introduce ./hugepages/page/[@size,@unit,@nodeset] qemu: Implement ./hugepages/page/[@size,@unit,@nodeset] tests: Some testing of hugepages mapping configure.ac | 4 +- docs/formatdomain.html.in | 18 +- docs/schemas/domaincommon.rng | 19 +- src/Makefile.am | 1 + src/conf/domain_conf.c | 197 +++++++++++++++++++-- src/conf/domain_conf.h | 13 +- src/libvirt_private.syms | 2 + src/parallels/parallels_driver.c | 2 +- src/qemu/qemu_capabilities.c | 2 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 111 ++++++++++-- src/qemu/qemu_conf.c | 124 +++++++++++-- src/qemu/qemu_conf.h | 9 +- src/qemu/qemu_driver.c | 39 ++-- src/qemu/qemu_process.c | 21 ++- src/util/virbitmap.c | 20 +++ src/util/virbitmap.h | 3 + src/util/virfile.c | 176 +++++++++++++++++- src/util/virfile.h | 12 ++ .../qemuxml2argv-hugepages-pages.args | 16 ++ .../qemuxml2argv-hugepages-pages.xml | 45 +++++ .../qemuxml2argv-hugepages-pages2.args | 10 ++ .../qemuxml2argv-hugepages-pages2.xml | 38 ++++ .../qemuxml2argv-hugepages-pages3.args | 9 + .../qemuxml2argv-hugepages-pages3.xml | 38 ++++ tests/qemuxml2argvdata/qemuxml2argv-hugepages.args | 2 +- tests/qemuxml2argvtest.c | 18 +- tests/qemuxml2xmltest.c | 3 + tests/virbitmaptest.c | 26 +++ 29 files changed, 884 insertions(+), 95 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-hugepages-pages.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-hugepages-pages.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-hugepages-pages2.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-hugepages-pages2.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-hugepages-pages3.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-hugepages-pages3.xml -- 1.8.5.5
