(1) boost-on-big policy make use of all big CPUs up to their full capacity before using the little CPUs. This improves performance on true b.L systems where the big CPUs have higher efficiency compared to the little CPUs. (2) boost-on-all policy place the tasks on the CPU having the highest spare capacity. This policy is optimal for SMP like systems. The scheduler sets the boost policy to boost-on-big on systems which has CPUs of different efficiencies. However it is possible that CPUs of the same micro architecture to have slight difference in efficiency due to other factors like cache size. Selecting the boost-on-big policy based on relative difference in efficiency is not optimal on such systems. The boost-policy device tree property is introduced to specify the required boost type and it overrides the default selection of boost type in the scheduler. The possible values for this property are "boost-on-big" and "boost-on-all". Change-Id: Iac19183fa7d4bfd9e5746b02a02b2b19cf64b78d Signed-off-by: Pavankumar Kondeti <pkondeti@codeaurora.org>

This happens when the all online CPUs are isolated and the allow isolated flag is set to false. In such cases, we have little choice but to use an isolated CPU and wait for core control to eventually un-isolate one or more online CPUs.

By selecting an idle CPU, it eliminates the chance of waker migrating to a different CPU after the wakee preempts it. This policy is also not susceptible to the incorrect "sync" usage i.e the waker does not goto sleep after waking up the wakee. However LPM exit latency associated with an idle CPU outweigh the above benefits on some targets. So add a knob to prefer the waker CPU having only 1 runnable task over idle CPUs in the waker cluster.

The assumption here is that higher capacity cluster will have higher power cost which may not be necessarily true for all platforms. Use power cost based checks instead of capacity based checks while applying the inter cluster migration restrictions.

Isolating and unisolating a CPU can be used in place of hotplug. Isolating and unisolating a CPU is faster than hotplug and can thus be used to optimize the performance and power of multi-core CPUs. Isolating works by migrating non-pinned IRQs and tasks to other CPUS and marking the CPU as not available to the scheduler and load balancer. Pinned tasks and IRQs are still allowed to run but it is expected that this would be minimal. Unisolation works by just marking the CPU available for scheduler and load balancer.

This knob can be tuned to apply aggregation only for the heavy workload applications. When this knob is enabled and load is aggregated, the load is not clipped to 100% @ current frequency to ramp up the frequency faster.

Similarly if any CPU other than maximum busy CPU has a pending notification, its group busy time is accounted twice. Maintain the frequency alert notification flag per frequency domain. When the notification is pending, don't clip the load to 100% @ fur for any of the CPUs in the frequency domain.

The CPU controller hasn't kept up with the various changes in the whole cgroup initialization / destruction sequence, and commit: 2e91fa7f6d45 ("cgroup: keep zombies associated with their original cgroups") caused it to explode. The reason for this is that zombies do not inhibit css_offline() from being called, but do stall css_released(). Now we tear down the cfs_rq structures on css_offline() but zombies can run after that, leading to use-after-free issues. The solution is to move the tear-down to css_released(), which guarantees nobody (including no zombies) is still using our cgroup. Furthermore, a few simple cleanups are possible too. There doesn't appear to be any point to us using css_online() (anymore?) so fold that in css_alloc(). And since cgroup code guarantees an RCU grace period between css_released() and css_free() we can forgo using call_rcu() and free the stuff immediately.

On CPU hotplug the steal time accounting can keep a stale rq->prev_steal_time value over CPU down and up. So after the CPU comes up again the delta calculation in steal_account_process_tick() wreckages itself due to the unsigned math: u64 steal = paravirt_steal_clock(smp_processor_id()); steal -= this_rq()->prev_steal_time; So if steal is smaller than rq->prev_steal_time we end up with an insane large value which then gets added to rq->prev_steal_time, resulting in a permanent wreckage of the accounting. As a consequence the per CPU stats in /proc/stat become stale. Nice trick to tell the world how idle the system is (100%) while the CPU is 100% busy running tasks. Though we prefer realistic numbers. None of the accounting values which use a previous value to account for fractions is reset at CPU hotplug time. update_rq_clock_task() has a sanity check for prev_irq_time and prev_steal_time_rq, but that sanity check solely deals with clock warps and limits the /proc/stat visible wreckage. The prev_time values are still wrong. Solution is simple: Reset rq->prev_*_time when the CPU is plugged in again.

The callers of steal_account_process_tick() expect it to return whether a jiffy should be considered stolen or not. Currently the return value of steal_account_process_tick() is in units of cputime, which vary between either jiffies or nsecs depending on CONFIG_VIRT_CPU_ACCOUNTING_GEN. If cputime has nsecs granularity and there is a tiny amount of stolen time (a few nsecs, say) then we will consider the entire tick stolen and will not account the tick on user/system/idle, causing /proc/stats to show invalid data. The fix is to change steal_account_process_tick() to accumulate the stolen time and only account it once it's worth a jiffy. (Thanks to Frederic Weisbecker for suggestions to fix a bug in my first version of the patch.)
