	sysconf(_SC_NPROCESSORS_CONF) (via get_nprocs_conf) reflects cpu_possible_mask, which is fixed at boot time, so querying it repeatedly is unnecessary. Replace multiple calls to sysconf(_SC_NPROCESSORS_CONF) with a single global nr_cpus variable initialized once at startup. `#pragma once` in timerlat_u.h is needed for pre-C23 compilers to avoid redefinition errors.

2026-03-04	tools/rtla: Add unit tests for utils.c	Costa Shulyupin
	Add unit tests for utility functions in src/utils.c using the Check testing framework. The tests verify parse_cpu_set(), strtoi(), and parse_prio() functions. Unit tests are built conditionally when libcheck is available. Run tests with 'make unit-test'. The test framework uses the Check library which provides process isolation for each test, preventing failures in one test from affecting others.
