H A Dcore-scheduling.rst105 During a schedule() event on any sibling of a core, the highest priority task on
106 the sibling's core is picked and assigned to the sibling calling schedule(), if
107 the sibling has the task enqueued. For rest of the siblings in the core,
114 switch to the new task immediately. If an idle task is selected for a sibling,
115 then the sibling is considered to be in a `forced idle` state. I.e., it may
