Let available compute capacity and estimated energy impact select wake-up target cpu when energy-aware scheduling is enabled. energy_aware_wake_cpu() attempts to find group of cpus with sufficient compute capacity to accommodate the task and find a cpu with enough spare capacity to handle the task within that group. Preference is given to cpus with enough spare capacity at the current OPP. Finally, the energy impact of the new target and the previous task cpu is compared to select the wake-up target cpu. cc: Ingo Molnar <mingo@redhat.com> cc: Peter Zijlstra <peterz@infradead.org> Signed-off-by: Morten Rasmussen <morten.rasmussen@arm.com>
