Add tests for memblock_alloc_try_nid() and memblock_alloc_try_nid_raw()
where the simulated physical memory is set up with multiple NUMA nodes.
Additionally, all of these tests set nid != 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
