memblock test: fix implicit declaration of function 'memparse'

2024-08-06T05:21:25+00:00

Commit 1e4c64b71c9b ("mm/memblock: Add "reserve_mem" to reserved named
memory at boot up") introduce the usage of memparse(), which is not
defined in memblock test.

Add the definition and link it to fix the build.

memblock tests: introduce range tests for memblock_alloc_exact_nid_raw

2022-11-08T07:50:24+00:00

Add TEST_F_EXACT flag, which specifies that tests should run
memblock_alloc_exact_nid_raw(). Introduce range tests for
memblock_alloc_exact_nid_raw() by using the TEST_F_EXACT flag to run the
range tests in alloc_nid_api.c, since memblock_alloc_exact_nid_raw() and
memblock_alloc_try_nid_raw() behave the same way when nid = NUMA_NO_NODE.

Rename tests and other functions in alloc_nid_api.c by removing "_try".
Since the test names will be displayed in verbose output, they need to
be general enough to refer to any of the memblock functions that the
tests may run.

memblock tests: change build options to run-time options

2022-07-20T07:46:33+00:00

Change verbose and movable node build options to run-time options.

Movable node usage:
    $ ./main -m

    Or:
    $ ./main --movable-node

Verbose usage:
    $ ./main -v

    Or:
    $ ./main --verbose

memblock tests: Makefile: add arguments to control verbosity

2022-07-04T16:58:27+00:00

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.

memblock tests: Add memblock_alloc_try_nid tests for top down

2022-03-09T13:54:04+00:00

Add tests for memblock_alloc_try_nid for top down allocation direction.
As the definition of this function is pretty close to the core
memblock_alloc_range_nid, the test cases implemented here cover most of
the code paths related to the memory allocations.

The tested scenarios are:
  - Region can be allocated within the requested range (both with aligned
    and misaligned boundaries)
  - Region can be allocated between two already existing entries
  - Not enough space between already reserved regions
  - Memory range is too narrow but memory can be allocated before
    the maximum address
  - Edge cases:
      + Minimum address is below memblock_start_of_DRAM()
      + Maximum address is above memblock_end_of_DRAM()

Add checks for both allocation directions:
  - Region starts at the min_addr and ends at max_addr
  - Maximum address is too close to the beginning of the available
    memory
  - Memory at the range boundaries is reserved but there is enough space
    to allocate a new region

memblock tests: Add memblock_alloc_from tests for top down

2022-03-09T13:54:03+00:00

Add checks for memblock_alloc_from for default allocation direction.
The tested scenarios are:
  - Not enough space to allocate memory at the minimal address
  - Minimal address parameter is smaller than the start address
    of the available memory
  - Minimal address is too close to the available memory

Add simple memblock_alloc_from test that can be used to test both
allocation directions (minimal address is aligned or misaligned).

memblock tests: Add memblock_alloc tests for top down

2022-03-09T13:53:18+00:00

Add checks for memblock_alloc for top down allocation direction.
The tested scenarios are:
  - Region can be allocated on the first fit (with and without
    region merging)
  - Region can be allocated on the second fit (with and without
    region merging)

Add checks for both allocation directions:
  - Region can be allocated between two already existing entries
  - Limited memory available
  - All memory is reserved
  - No available memory registered with memblock

between different test cases. Add a function that sets all fields to
their default values.
