memblock tests: add labels to verbose output for generic alloc tests

2022-08-30T10:12:00+00:00

Generic tests for memblock_alloc*() functions do not use separate functions for testing top-down and bottom-up allocation directions. Therefore, the function name that is displayed in the verbose testing output does not include the allocation direction. Add an additional prefix when running generic tests for memblock_alloc*() functions that indicates which allocation direction is set. The prefix will be displayed when the tests are run in verbose mode.

memblock tests: update zeroed memory check for memblock_alloc_* tests

2022-08-30T10:12:00+00:00

Update the assert in memblock_alloc_try_nid() and memblock_alloc_from() tests that checks whether the memory is cleared so that it checks the entire chunk of allocated memory instead of just the first byte.

memblock tests: add verbose output to memblock tests

2022-07-04T16:58:28+00:00

Add and use functions and macros for printing verbose testing output. If the Memblock simulator was compiled with VERBOSE=1: - prefix_push(): appends the given string to a prefix string that will be printed in test_fail() and test_pass*(). - prefix_pop(): removes the last prefix from the prefix string. - prefix_reset(): clears the prefix string. - test_fail(): prints a message after a test fails containing the test number of the failing test and the prefix. - test_pass(): prints a message after a test passes containing its test number and the prefix. - test_print(): prints the given formatted output string. - test_pass_pop(): runs test_pass() followed by prefix_pop(). - PREFIX_PUSH(): runs prefix_push(__func__). If the Memblock simulator was not compiled with VERBOSE=1, these functions/macros do nothing. Add the assert wrapper macros ASSERT_EQ(), ASSERT_NE(), and ASSERT_LT(). If the assert condition fails, these macros call test_fail() before executing assert().

memblock tests: Add memblock_alloc_from tests for bottom up

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

Add checks for memblock_alloc_from for bottom up 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 parameter is too close to the end of the available memory Add test case wrappers to test both directions in the same context.

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).
