linux-toradex.git/tools/testing/memblock/README, branch master Linux kernel for Apalis and Colibri modules tools/testing/memblock: fix stale NUMA reservation tests 2026-06-02T05:34:03+00:00 Priyanshu Kumar priyanshukumarpu@gmail.com 2026-04-15T12:27:31+00:00 9588076fb21992a5d14efeb99134ebf034c7b84f memblock allocations now reserve memory with MEMBLOCK_RSRV_KERN and, on NUMA configurations, record the requested node on the reserved region. Several memblock simulator NUMA tests still expected merges that only worked before those reservation semantics changed, so the suite aborted even though the allocator behavior was correct. Update the NUMA merge expectations in the memblock_alloc_try_nid() and memblock_alloc_exact_nid_raw() tests to match the current reserved region metadata rules. For cases that should still merge, create the pre-existing reservation with matching nid and MEMBLOCK_RSRV_KERN metadata. Also strengthen the memblock_alloc_node() coverage by checking the newly created reserved region directly instead of re-reading the source memory node descriptor. Finally, drop the stale README/TODO notes that still claimed memblock_alloc_node() could not be tested. The memblock simulator passes again with NUMA enabled after these updates.

memblock allocations now reserve memory with MEMBLOCK_RSRV_KERN and,
on NUMA configurations, record the requested node on the reserved
region. Several memblock simulator NUMA tests still expected merges
that only worked before those reservation semantics changed, so the
suite aborted even though the allocator behavior was correct.

Update the NUMA merge expectations in the memblock_alloc_try_nid()
and memblock_alloc_exact_nid_raw() tests to match the current reserved
region metadata rules. For cases that should still merge, create the
pre-existing reservation with matching nid and MEMBLOCK_RSRV_KERN
metadata. Also strengthen the memblock_alloc_node() coverage by
checking the newly created reserved region directly instead of
re-reading the source memory node descriptor.

Finally, drop the stale README/TODO notes that still claimed
memblock_alloc_node() could not be tested.

The memblock simulator passes again with NUMA enabled after these
updates.

memblock tests: Makefile: add arguments to control verbosity 2022-07-04T16:58:27+00:00 Rebecca Mckeever remckee0@gmail.com 2022-07-04T04:06:55+00:00 946dccb35d74079436677afcdc767d0406e99a88 Add VERBOSE and MEMBLOCK_DEBUG user-provided arguments. VERBOSE will enable verbose output from Memblock simulator. MEMBLOCK_DEBUG will enable memblock_dbg() messages. Update the help message to include VERBOSE and MEMBLOCK_DEBUG. Update the README to include VERBOSE. The README does not include all available options and refers to the help message for the remaining options. Therefore, omit MEMBLOCK_DEBUG from README.
