This library defines get_allowed_nodes() and get_allowed_nodes_arr() functions to obtain list of nodes tests can use. I tested it with following setups. Note that setup 4 and 5 will end with TCONF as there is only 1 node with memory. 1. # numactl -H available: 8 nodes (2,4-10) node 2 cpus: 0 node 2 size: 127 MB node 2 free: 9 MB node 4 cpus: node 4 size: 128 MB node 4 free: 9 MB node 5 cpus: node 5 size: 128 MB node 5 free: 64 MB node 6 cpus: node 6 size: 128 MB node 6 free: 121 MB node 7 cpus: node 7 size: 128 MB node 7 free: 121 MB node 8 cpus: node 8 size: 128 MB node 8 free: 121 MB node 9 cpus: node 9 size: 128 MB node 9 free: 121 MB node 10 cpus: node 10 size: 127 MB node 10 free: 123 MB 2. # numactl -H available: 4 nodes (0-3) node 0 cpus: 0 1 2 3 4 5 node 0 size: 2047 MB node 0 free: 564 MB node 1 cpus: 6 7 8 9 10 11 node 1 size: 2046 MB node 1 free: 451 MB node 2 cpus: 18 19 20 21 22 23 node 2 size: 2048 MB node 2 free: 595 MB node 3 cpus: 12 13 14 15 16 17 node 3 size: 2048 MB node 3 free: 236 MB node distances: node 0 1 2 3 0: 10 16 16 16 1: 16 10 16 16 2: 16 16 10 16 3: 16 16 16 10 3. # numactl -H available: 2 nodes (2-3) node 2 cpus: 0 node 2 size: 511 MB node 2 free: 154 MB node 3 cpus: node 3 size: 511 MB node 3 free: 490 MB 4. # numactl -H available: 2 nodes (0-1) node 0 cpus: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 node 0 size: 0 MB node 0 free: 0 MB node 1 cpus: node 1 size: 12288 MB node 1 free: 9689 MB node distances: node 0 1 0: 10 40 1: 40 10 5. # numactl -H available: 1 nodes (0) node 0 cpus: 0 node 0 size: 1023 MB node 0 free: 654 MB node distances: node 0 0: 10 Jan Stancek (4): add libnuma_helper mbind01: dont use hardcoded NUMA node ids get_mempolicy01: dont use hardcoded NUMA node ids move_pages: dont use hardcoded NUMA node ids testcases/kernel/syscalls/get_mempolicy/Makefile | 7 +- .../syscalls/get_mempolicy/get_mempolicy01.c | 8 +- testcases/kernel/syscalls/mbind/Makefile | 3 +- testcases/kernel/syscalls/mbind/mbind01.c | 9 +- testcases/kernel/syscalls/move_pages/Makefile | 5 +- .../kernel/syscalls/move_pages/move_pages02.c | 11 +- .../kernel/syscalls/move_pages/move_pages03.c | 11 +- .../kernel/syscalls/move_pages/move_pages04.c | 11 +- .../kernel/syscalls/move_pages/move_pages05.c | 11 +- .../kernel/syscalls/move_pages/move_pages06.c | 9 +- .../kernel/syscalls/move_pages/move_pages07.c | 11 +- .../kernel/syscalls/move_pages/move_pages08.c | 9 +- .../kernel/syscalls/move_pages/move_pages09.c | 7 +- .../kernel/syscalls/move_pages/move_pages10.c | 11 +- .../kernel/syscalls/move_pages/move_pages11.c | 11 +- .../syscalls/move_pages/move_pages_support.c | 44 +++++-- .../syscalls/move_pages/move_pages_support.h | 1 + testcases/kernel/syscalls/numa/Makefile | 22 +++ testcases/kernel/syscalls/numa/Makefile.inc | 27 ++++ testcases/kernel/syscalls/numa/lib/Makefile | 26 ++++ testcases/kernel/syscalls/numa/lib/numa_helper.c | 135 ++++++++++++++++++++ testcases/kernel/syscalls/numa/lib/numa_helper.h | 34 +++++ 22 files changed, 361 insertions(+), 62 deletions(-) create mode 100644 testcases/kernel/syscalls/numa/Makefile create mode 100644 testcases/kernel/syscalls/numa/Makefile.inc create mode 100644 testcases/kernel/syscalls/numa/lib/Makefile create mode 100644 testcases/kernel/syscalls/numa/lib/numa_helper.c create mode 100644 testcases/kernel/syscalls/numa/lib/numa_helper.h --------------1.7.1 Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
