However, on a real system it can be difficult to identify a single value for the knob which fits the needs of multiple different tasks. For example, some kernel threads and/or user-space background services should be better managed the "standard" way while we still want to be able to boost the performance of specific workloads. In order to improve the flexibility of the task boosting mechanism this patch is the first of a small series which extends the previous implementation to introduce a "per task group" support. This first patch introduces just the basic CGroups support, a new "schedtune" CGroups controller is added which allows to configure different boost value for different groups of tasks. To keep the implementation simple but still effective for a boosting strategy, the new controller: 1. allows only a two layer hierarchy 2. supports only a limited number of boost groups A two layer hierarchy allows to place each task either: a) in the root control group thus being subject to a system-wide boosting value b) in a child of the root group thus being subject to the specific boost value defined by that "boost group" The limited number of "boost groups" supported is mainly motivated by the observation that in a real system it could be useful to have only few classes of tasks which deserve different treatment. For example, background vs foreground or interactive vs low-priority. As an additional benefit, a limited number of boost groups allows also to have a simpler implementation especially for the code required to compute the boost value for CPUs which have runnable tasks belonging to different boost groups.

This results into use after free: xhci_mem_clean() called from xhci_plat_remove() freeing the xhci virtual device when a structure member is being accessed by xhci_alloc_virt_device() after virtual device allocation as part of connect hub event. deadlock: Upon device disconnect if stop endpoint command remains pending xhci_mem_cleanup() frees xhci virtual device which also frees up endpoint stop_cmd_timer. udev->dev lock is held until cancelled urb is not given back to class driver. In a different context xhci platform remove calls usb_disconnect() on children of root hub which tries to acquire the same udev->dev lock this results into a dead lock condition. Fix issues by making sure hub events are flushed before xhci is stopped. Change-Id: I86d414bca17464d1dff3346ec668d8b3efec1652 Signed-off-by: Hemant Kumar <hemantk@codeaurora.org>

To support tasks performance boosting the scheduler should provide a "knob" which allows to tune how much the system is going to be optimised for energy efficiency vs performance. This patch is the first of a series which provides a simple interface to define a tuning knob. One system-wide "boost" tunable is exposed via: /proc/sys/kernel/sched_cfs_boost which can be configured in the range [0..100], to define a percentage where: - 0% boost requires to operate in "standard" mode by scheduling tasks at the minimum capacities required by the workload demand - 100% boost requires to push at maximum the task performances, "regardless" of the incurred energy consumption A boost value in between these two boundaries is used to bias the power/performance trade-off, the higher the boost value the more the scheduler is biased toward performance boosting instead of energy efficiency.

If most of the history says the pattern of residencies is repeating with minimal deviation then use the average of these for predicting the next mode to enter. If the pattern is not repeating then if more than 50 percent of the samples out of history have exited a low power mode earlier than the minumim residency of that mode, restrict it and also low power modes deeper than that. In any of the above case, trigger a hrtimer to wakeup cpu with timeout as predicted+delta or max residency of the mode selected if a deeper state can be selected after waking up incase if prediction goes wrong.

The latency of the synchronize_sched() is too high for cgroups. The commit 1ed1328792ff talks about the write path being a fairly cold path but this is not the case for Android which moves task to the foreground cgroup and back around binder IPC calls from foreground processes to background processes, so it is significantly hotter than human initiated operations. Switch cgroup_threadgroup_rwsem into the slow mode for now to avoid the problem, hopefully it should not be that slow after another commit 80127a39681b ("locking/percpu-rwsem: Optimize readers and reduce global impact"). We could just add rcu_sync_enter() into cgroup_init() but we do not want another synchronize_sched() at boot time, so this patch adds the new helper which doesn't block but currently can only be called before the first use.

This patch cures this problem by ordering the reader-state vs reader-count (see the comments in __percpu_down_read() and percpu_down_write()). This changes a global atomic op into a full memory barrier, which doesn't have the global cacheline contention. This also enables using the percpu-rwsem with rcu_sync disabled in order to bias the implementation differently, reducing the writer latency by adding some cost to readers.
