111 * Query the idle time (in µs) of a CPU.
113 * \param cpus Set of CPUs to query. Only the idle time of the first
115 * \param[out] us Idle time of queried CPU in µs.
120 * This function retrieves the idle time in µs of the first selected
121 * CPU in `cpus.map`. The idle time is the accumulated time a CPU has spent in
123 * has to retrieve the idle time at the beginning (`i1`) and the end (`i2`)
124 * of a known time interval `t`. The load is then calculated as
127 * The idle time is only defined for online CPUs. Reading the idle time from

133 * up-to-date idle time you should use a thread running on the same CPU of
134 * which the idle time is requested.
