Dsched-design-CFS.rst34 p->se.vruntime (nanosec-unit) value. This way, it's possible to accurately
38 p->se.vruntime value --- i.e., tasks would execute simultaneously and no task
41 CFS's task picking logic is based on this p->se.vruntime value and it is thus
42 very simple: it always tries to run the task with the smallest p->se.vruntime
62 increasing value tracking the smallest vruntime among all tasks in the
72 p->se.vruntime key. CFS picks the "leftmost" task from this tree and sticks to it.
81 p->se.vruntime. Once p->se.vruntime gets high enough so that another task
