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(). This function uses a previously allocated dummy physical memory. It 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. --- Changelog v4 -> v5 Based on feedback from David Hildenbrand: PATCH 1: - tests/common.c: + setup_numa_memblock(): * Change nodes[] to int basis points (one hundredth of 1% or 1/10000) instead of phys_addr_t fraction denominators * Rename parameter nodes[] to node_fracs[] PATCH 2: - tests/alloc_nid_api.c: + Update node_fractions[] to reflect changes in PATCH 1 v3 -> v4 Based on feedback from David Hildenbrand: PATCH 1: - tests/common.h: + Remove #define MEM_FACTOR PATCH 2: - tests/alloc_nid_api.c: + Add missing blank line after alloc_nid_test_flags = flags; PATCH 2, PATCH 3, PATCH 4: - tests/alloc_nid_api.c: + Define variables in new tests in a single block + Change "cleared memory region" to "memory region" in comment blocks for new tests Based on feedback from Mike Rapoport: PATCH 1: - tests/common.c: + Remove node_sizes[] array - tests/common.c, tests/common.h: + Combine setup_numa_memblock_generic() and setup_numa_memblock(): * Remove setup_numa_memblock(void) * Change setup_numa_memblock_generic() to setup_numa_memblock() and remove the factor and node_cnt parameters * Change nodes[] parameter to an array containing the * denominators of the fractions of MEM_SIZE contained in each node e.g., if nodes[0] = SZ_8, node 0 will contain 1/8th of MEM_SIZE PATCH 2: - tests/alloc_nid_api.c: + Add node_fractions[] array: * Based on values from node_sizes[] array previously in PATCH 1 * Update to fit the new nodes[] parameter of * setup_numa_memblock() v2 -> v3 PATCH 2, PATCH 3, PATCH 4: - tests/alloc_nid_api.c: + Edits for consistency between tests and test naming styles: * Change "numa_top_down" to "top_down_numa" * Change "numa_bottom_up" to "bottom_up_numa" * Move "generic" to immediately before "check" * alloc_try_nid_bottom_up_numa_small_node_check() and alloc_try_nid_bottom_up_numa_node_reserved_check(): - Separate size definition from its declaration Updates based on changes to the dependent patch set noted above: PATCH 2, PATCH 3, PATCH 4: - tests/alloc_nid_api.c: + get_func_testing(): * Rename to get_memblock_alloc_try_nid_name(). + Update calls to verify_mem_content() to assert_mem_content(). 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. --- Rebecca Mckeever (4): memblock tests: add simulation of physical memory with multiple NUMA nodes memblock tests: add top-down NUMA tests for memblock_alloc_try_nid* memblock tests: add bottom-up NUMA tests for memblock_alloc_try_nid* memblock tests: add generic NUMA tests for memblock_alloc_try_nid* .../testing/memblock/scripts/Makefile.include | 2 +- tools/testing/memblock/tests/alloc_nid_api.c | 1466 ++++++++++++++++- tools/testing/memblock/tests/alloc_nid_api.h | 16 + tools/testing/memblock/tests/common.c | 31 + tools/testing/memblock/tests/common.h | 22 +- 5 files changed, 1524 insertions(+), 13 deletions(-) -- 2.25.1
