Message-Id: <cover.1664753534.git.remckee0@gmail.com> Date: Sun, 2 Oct 2022 18:41:33 -0500 From: Rebecca Mckeever <remckee0@...il.com> To: Mike Rapoport <rppt@...nel.org>, linux-mm@...ck.org, linux-kernel@...r.kernel.org Cc: David Hildenbrand <david@...hat.com>, Rebecca Mckeever <remckee0@...il.com> Subject: [PATCH v2 0/5] memblock tests: add tests for memblock_alloc_exact_nid_raw These patches add tests for memblock_alloc_exact_nid_raw(). There are two sets of tests: range tests and NUMA tests. The range tests use a normal (i.e., UMA) simulated physical memory and set the nid to NUMA_NO_NODE. The NUMA tests use a simulated physical memory that is set up with multiple NUMA nodes. Additionally, most of these tests set nid != NUMA_NO_NODE. The range tests are very similar to the range tests for memblock_alloc_try_nid_raw(). The NUMA tests have the same setup as the corresponding test for memblock_alloc_try_nid_raw(), but several of the memblock_alloc_exact_nid_raw() tests fail to allocate memory in setups where the memblock_alloc_try_nid_raw() test would allocate memory. Also, some memblock_alloc_exact_nid_raw() tests drop the lower limit of the requested range in order to allocate within the requested node, but the same setup in a memblock_alloc_try_nid_raw() test allocates within the requested range. --- Changelog v1 -> v2 PATCH 0: - Add missing memblock_alloc_exact_nid_raw to subject line --- Rebecca Mckeever (5): memblock tests: add range tests for memblock_alloc_exact_nid_raw memblock tests: add top-down NUMA tests for memblock_alloc_exact_nid_raw memblock tests: add bottom-up NUMA tests for memblock_alloc_exact_nid_raw memblock tests: add generic NUMA tests for memblock_alloc_exact_nid_raw memblock tests: remove completed TODO item tools/testing/memblock/Makefile | 2 +- tools/testing/memblock/TODO | 7 +- tools/testing/memblock/main.c | 2 + .../memblock/tests/alloc_exact_nid_api.c | 2299 +++++++++++++++++ .../memblock/tests/alloc_exact_nid_api.h | 25 + 5 files changed, 2328 insertions(+), 7 deletions(-) create mode 100644 tools/testing/memblock/tests/alloc_exact_nid_api.c create mode 100644 tools/testing/memblock/tests/alloc_exact_nid_api.h -- 2.25.1
