H A Dsched-capacity.rst2 Capacity Aware Scheduling
5 1. CPU Capacity
16 CPU capacity is a measure of the performance a CPU can reach, normalized against
18 asymmetric CPU capacity systems, as they contain CPUs of different capacities.
20 Disparity in maximum attainable performance (IOW in maximum CPU capacity) stems
36 capacity(cpu) = work_per_hz(cpu) * max_freq(cpu)
41 Two different capacity values are used within the scheduler. A CPU's
42 ``capacity_orig`` is its maximum attainable capacity, i.e. its maximum
43 attainable performance level. A CPU's ``capacity`` is its ``capacity_orig`` to
