Same as #88767, we can make it bulletproof by BUILD_ASSERTing CONFIG_DYNAMIC_THREAD_POOL_SIZE>=2

This needs another change unfortunately - it should be visible after a rebase, but due to #88538, the default heap-add with I'll add another commit ahead of this one to create a heap-add for posix semaphores. https://github.com/zephyrproject-rtos/zephyr/actions/runs/14535678361/job/40783625837?pr=88762 The above failure can be traced to zephyr/lib/posix/options/semaphore.c Line 275 in e41909a |

@nashif - this should reduce test execution time for semaphores by a good amount (for cortex-a53, and likely x86-64 as well) |

The implementation of POSIX_SEMAPHORES historically used heap allocation and has not yet been transitioned to a pool allocator. However, since 590258b, the default heap-add with CONFIG_POSIX_API has been reduced from 1 kiB which causes tests/posix/semaphores to fail due to NULL being returned from a call to k_calloc(). Create a minimal heap-add for the POSIX_SEMAPHORES Option Group. This can be removed at a future date if semaphores are changed to use a pooled allocator and fixed-size name, rather than heap allocation. Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>

Is this supposed to be in the second commit?

Yeah, probably not.
I've actually been working on a timespec_util.h header as well that includes a few useful functions. That's been long overdue.

There is no reason to use a 5s wait time in tests. This can add up quite significantly across multiple platforms that execute in real-time under qemu (or even just on real hardware). Speedup observed with qemu_cortex_a53/qemu_cortex_a53/smp Before: ``` START - test_named_semaphore PASS - test_named_semaphore in 5.688 seconds ``` After: ``` START - test_named_semaphore PASS - test_named_semaphore in 0.783 seconds ``` Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>
Just a formatting change, in a separate commit. Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>
Commit f7633a5 moved the tests for the POSIX_SEMAPHORES Option Group from the tests/posix/common testsuite to its own dedicated testsuite. However, there was a copy-paste error. Previously, tests would have been run only once when dynamic threads were enabled, and then skipped when dynamic threads were disabled, since that follows the posix programming model better. However, dynamic threads were never actually enabled after moving to the new testsuite. So all tests were effectively skipped. Add the necessary options to prj.conf in order to ensure that there are sufficient dynamic threads available to run the testsuite. Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>
