Additionally, all of these tests set nid !=3D NUMA_NO_NODE. These tests are run with a bottom-up allocation direction. The tested scenarios are: Range unrestricted: - region can be allocated in the specific node requested: + there are no previously reserved regions + the requested node is partially reserved but has enough space - the specific node requested cannot accommodate the request, but the region can be allocated in a different node: + there are no previously reserved regions, but node is too small + the requested node is fully reserved + the requested node is partially reserved and does not have enough space Range restricted: - region can be allocated in the specific node requested after dropping min_addr: + range partially overlaps with two different nodes, where the first node is the requested node + range partially overlaps with two different nodes, where the requested node ends before min_addr - region cannot be allocated in the specific node requested, but it can be allocated in the requested range: + range overlaps with multiple nodes along node boundaries, and the requested node ends before min_addr + range overlaps with multiple nodes along node boundaries, and the requested node starts after max_addr - region cannot be allocated in the specific node requested, but it can be allocated after dropping min_addr: + range partially overlaps with two different nodes, where the second node is the requested node Signed-off-by: Rebecca Mckeever --- tools/testing/memblock/tests/alloc_nid_api.c | 584 +++++++++++++++++++ 1 file changed, 584 insertions(+) diff --git a/tools/testing/memblock/tests/alloc_nid_api.c b/tools/testing/m= emblock/tests/alloc_nid_api.c index 3ffd042298f1..112cd8018d7c 100644 --- a/tools/testing/memblock/tests/alloc_nid_api.c +++ b/tools/testing/memblock/tests/alloc_nid_api.c @@ -1826,12 +1826,578 @@ static int alloc_try_nid_numa_top_down_no_overlap_= high_check(void) return 0;
