| |
These patches add additional tests for memblock_alloc_try_nid() and memblock_alloc_try_nid_raw() that use a simulated physical memory that is set up with multiple NUMA nodes. Additionally, most of these tests set nid != NUMA_NO_NODE.
To set up a simulated physical memory with multiple NUMA nodes, patch 1 introduces setup_numa_memblock_generic() and setup_numa_memblock(). These functions use a previously allocated dummy physical memory. They can be used in place of setup_memblock() in tests that need to simulate a NUMA system.
These tests are run twice, once for memblock_alloc_try_nid() and once for memblock_alloc_try_nid_raw(), so that both functions are tested with the same set of tests. When the tests run memblock_alloc_try_nid(), they test that the entire memory region is zero. When the tests run memblock_alloc_try_nid_raw(), they test that the entire memory region is nonzero.
Note: This patch set depends on the following patch set: https://lore.kernel.org/all/cover.1660897732.git.remckee0@gmail.com
--- Changelog
v1 -> v2 Updates based on changes to the dependent patch set noted above: PATCH 2, PATCH 3, PATCH 4: - tests/alloc_nid_api.c: - Update calls to verify_mem_content() to include the flags parameter required by the new, common verify_mem_content() function. ---
