sched: Use Per-Entity-Load-Tracking metric for load balancing
From: Preeti U Murthy
Currently the load balancer weighs a task based upon its priority,and this
weight consequently gets added up to the weight of the run queue that it is
on.It is this weight of the runqueue that sums up to a sched
Hi everyone
I conducted a few experiments with a workload to compare the following
parameters with this patchset and without this patchset:
1.The performance of the workload
2.The sum of the waitime to run of the processes queued on each cpu-the
cumulative latency.
3.The number of migrations of
We boot the kernel in non-secure mode and by default access to
the CCI device is not enabled for non-secure access, so we must
enable this if we want Linux to manage CPU hotplug on big.LITTLE
models.

Changes since V1:
- Add a DSB instructions

From: "Rajanikanth H.V"
dt property, 'battery-type' shall be one of supported technology type
instead blank.
refer:Documentation/devicetree/bindings/power_supply/ab8500/fg.txt
for the list of supported types
thanks to Francesco Lavra for highlighting missing of_node_put(...)
for '3.7-rc5'
From: "Rajanikanth H.V"
ab8500_fg driver prepares instance list of fuelgauge which is
required by btemp driver for battery identification. So make sure
that ab8500 fuelgauge list is ready before btemp driver starts.

The nr_busy_cpus field of the sched_group_power is sometime different from 0
whereas the platform is fully idle. This serie fixes 3 use cases:
- when the SCHED softirq is raised on an idle core for idle load balance but
the platform doesn't go out of the cpuidle state
- when some CPUs enter id
The function nohz_kick_needed modifies NOHZ_IDLE flag that is used to update
the nr_busy_cpus of the sched_group.
When the sched_domain are updated (because of the unplug of a CPUs as an
example) a null_domain is attached to CPUs. We have to test
likely(!on_null_domain(cpu) first in order to detect
With the coupled cpuidle driver (but probably also with other drivers),
a CPU loops in a temporary safe state while waiting for other CPUs of its
cluster to be ready to enter the coupled C-state. If an IRQ or a softirq
occurs, the CPU will stay in this internal loop if there is no need
to resched.
On my smp platform which is made of 5 cores in 2 clusters,I have the
nr_busy_cpus field of sched_group_power struct that is not null when the
platform is fully idle. The root cause seems to be:
During the boot sequence, some CPUs reach the idle loop and set their
NOHZ_IDLE flag while waiting for ot
