requires it to wait 1ms. This adds a msleep(1) before polling the

If load is above go_hispeed_load, always go to at least hispeed_freq,

For systems that set a common speed for all CPUs, checking current

Add checks for error return from cpufreq_frequency_table_target, and be
less noisy on the existing call with an error check. CPU hotplug and
system shutdown may cause this call to return -EINVAL.

The cpufreq TRANSTION notifier callback does not check the
governor_enabled state on affected CPUS, which will case
kernel panic in update_load because the policy object maybe
NULL or invalid when governor_enabled is false.

Devices may register an intermediate retention state into the domain
upon attaching. Currently generic domain would register an array of
states upon init. This patch prepares for later insertion (sort per
depth, remove).

Reschedule load sampling timer after timestamp of sample start taken,
hold spinlock across entire sequence to avoid preemption. Avoid the

Previously the idle time returned from get_cpu_idle_time_us included the
iowait time. So the iowait time was always calculated as idle time.
But now the idle time returned from get_cpu_idle_time_us does not include
the iowait time anymore because of below commit which cause

Cpufreq no longer calls governor callback for offlined cpus. i.e. All
policy->cpus are guaranteed to be online. Hence we don't need explicit check to
see if cpu is online or not.

Hi Lina,
this is the rebased version of my patches to handle cluster sleep with genpd.
I rebased over your current patches in the linaro git, and Axels v10, and
finally linux-next.
The arm64/Juno stuff is mainly for testing, it may not be 100% up-to-date with
the CPU-pd discussion outcomes, and
