CFS maintains a time-ordered rbtree, where all runnable tasks are sorted by the -p->se.vruntime key (there is a subtraction using rq->cfs.min_vruntime to -account for possible wraparounds). CFS picks the "leftmost" task from this -tree and sticks to it. +p->se.vruntime key. CFS picks the "leftmost" task from this tree and sticks to it. As the system progresses forwards, the executed tasks are put into the tree more and more to the right --- slowly but surely giving a chance for every task to become the "leftmost task" and thus get on the CPU within a deterministic |
