This sets the maximum -allowed extension in nanoseconds before scheduling of the task is enforced. -Default value is 10000ns (10us). The possible range is 10000ns (10us) to -50000ns (50us). - -This value has a direct correlation to the worst case scheduling latency; -increment at your own risk. sched_energy_aware ================== -- cgit v1.2.3
