[RFCv5 PATCH 23/46] sched: Extend sched_group_energy to test load-balancing...
Extended sched_group_energy() to support energy prediction with usage (tasks) added/removed from a specific cpu or migrated between a pair of cpus. Useful for load-balancing decision making. cc: Ingo...
View Article[RFCv5 PATCH 22/46] sched: Calculate energy consumption of sched_group
For energy-aware load-balancing decisions it is necessary to know the energy consumption estimates of groups of cpus. This patch introduces a basic function, sched_group_energy(), which estimates the...

arch_scale_cpu_capacity() is no longer a weak function but a #define instead. Include the #define in topology.h. cc: Russell King <linux@arm.linux.org.uk> Signed-off-by: Morten Rasmussen...
View Article[RFCv5 PATCH 19/46] sched: Compute cpu capacity available at current frequency
capacity_orig_of() returns the max available compute capacity of a cpu. For scale-invariant utilization tracking and energy-aware scheduling decisions it is useful to know the compute capacity...
View Article[RFCv5 PATCH 14/46] sched: Make energy awareness a sched feature
This patch introduces the ENERGY_AWARE sched feature, which is implemented using jump labels when SCHED_DEBUG is defined. It is statically set false when SCHED_DEBUG is not defined. Hence this doesn't...
View Article[RFCv5 PATCH 17/46] sched: Introduce SD_SHARE_CAP_STATES sched_domain flag
cpufreq is currently keeping it a secret which cpus are sharing clock source. The scheduler needs to know about clock domains as well to become more energy aware. The SD_SHARE_CAP_STATES domain flag...
