182 * idle core is found by the default ops.select_cpu() implementation,
187 * default ops.select_cpu implementation. The behavior of the scheduler

268 1. When a task is waking up, ``ops.select_cpu()`` is the first operation
272 The CPU selected by ``ops.select_cpu()`` is an optimization hint and not
275 ``ops.select_cpu()`` returns matches the CPU the task eventually runs on.
279 using ``ops.select_cpu()`` judiciously can be simpler and more efficient.
284 A task can be immediately inserted into a DSQ from ``ops.select_cpu()``
