Dietmar Eggemann 799fe13ed5 sched: Introduce energy data structures ... The struct sched_group_energy represents the per sched_group related data which is needed for energy aware scheduling. It contains: (1) number of elements of the idle state array (2) pointer to the idle state array which comprises 'power consumption' for each idle state (3) number of elements of the capacity state array (4) pointer to the capacity state array which comprises 'compute capacity and power consumption' tuples for each capacity state The struct sched_group obtains a pointer to a struct sched_group_energy. The function pointer sched_domain_energy_f is introduced into struct sched_domain_topology_level which will allow the arch to pass a particular struct sched_group_energy from the topology shim layer into the scheduler core. The function pointer sched_domain_energy_f has an 'int cpu' parameter since the folding of two adjacent sd levels via sd degenerate doesn't work for all sd levels. I.e. it is not possible for example to use this feature to provide per-cpu energy in sd level DIE on ARM's TC2 platform. It was discussed that the folding of sd levels approach is preferable over the cpu parameter approach, simply because the user (the arch specifying the sd topology table) can introduce less errors. But since it is not working, the 'int cpu' parameter is the only way out. It's possible to use the folding of sd levels approach for sched_domain_flags_f and the cpu parameter approach for the sched_domain_energy_f at the same time though. With the use of the 'int cpu' parameter, an extra check function has to be provided to make sure that all cpus spanned by a sched group are provisioned with the same energy data. cc: Ingo Molnar <mingo@redhat.com> cc: Peter Zijlstra <peterz@infradead.org> Signed-off-by: Dietmar Eggemann <dietmar.eggemann@arm.com>		2016-03-21 12:34:30 +00:00
