Pause will not be invoked through core control until after
walt has been initialized. However, the walt_pause apis are
made available to other vendor modules, and if those modules
attempt to invoke pause prior to walt being initialized, an
invalid reference to walt_drain_thread will be made.
Prevent the walt_pause and walt_resume apis from being used
until after walt has been properly initialized, walt_halt_init
has been called, and walt_drain_thread properly created.

We have a legacy sysfs interface to change the USB operating mode. Since
usb_role callbacks are available for user space and UCSI, there is
really no need for mode sysfs interface. For the sake of not breaking
any existing use cases, keep the mode interface but re-use the usb_role
callbacks. The usb-role-switch is an optional property, so refactor
the role switch ops so that they can be called even when this property
is not available but mode sysfs interface can be made available. Note that
there is no visible change to the user space.

migrate_disable is called to prevent moving a task to a different
cpu. In the process it will update the task's cpus_ptr to a
temporary mask to restrict the task to run only on the current
cpu. It has only one cpu set in this new mask. migrate_disable
must always be paired with a migrate_enable call.
When migrate_enable is called it will attempt to manipulate the
allowed ptrs mask just prior to actually enabling migration on
a task. This means __set_cpus_allowed_ptr is called. This calls
a tracehook:
migrate_enable
__set_cpus_allowed_ptr
__set_cpus_allowed_ptr_locked
trace_android_rvh_set_cpus_allowed_ptr_locked
android_rvh_set_cpus_allowed_ptr_locked
The purpose of handling this hook in walt, is to prevent the
assignment of a task to a halted cpu. When migrate_enable
restores the affinity to p->cpus_mask and p->cpus_mask consists
of a single cpu and that single cpu is halted, WALT will cause
__set_cpus_allowed_ptr to reject and return early. IOW
p->cpus_ptr is not set to p->cpus_mask.
If the p->cpus_ptr is not restored to point to the p->cpus_mask,
a subsequent migrate_disable/migrate_enable can happen, and
is allowed to happen with the runque lock taken. Since the
p->cpus_ptr is not pointing to the p->cpus_mask, migrate_enable
will incorrectly call __set_cpus_allowed_ptr. This in turn
will take the runque lock again resulting in a spinlock
recursion.
Address this by updating the hook code, checking the
migrate_disabled flag for the task, and allowing the existing
cpu to be used even if that cpu is halted. To achieve this
utilize a different hook that is present in the code already:
trace_android_rvh_set_cpus_allowed_by_task().

Certain frequencies in min-cap cpus draw excessive power and
are more costly to the device's performance than indicated by
the energy model.
For silver frequencies above a threshold, inflate the cost by
a percentage to create a steep power curve, favoring golds at
lower frequencies. For example, to raise the cost for
frequencies above 1.6GHz by 3x:
echo 300 > /proc/sys/walt/sched_em_inflate_pct
echo 220 > /proc/sys/walt/sched_em_inflate_thres

"trace_binder_transaction_received" vendor hook is used to clear binder low
latency MVP priority, but for some usecase it is observed that usespace
application is initiating read ioctl quickly and as part of ioctl handling
binder driver initiates transaction received vendor hook and binder low
latency MVP priority is cleared for the binder thread.
Handle above condition by allowing binder thread to maintain and run with
MVP priority for it's allocated MVP timeslice.
The Low latency flag of the task is reset only when the binder transactions
is initiated again on the same thread and task initiating the transaction
doesn't comply with the low latency criterion.

Core control takes a numeric input for the not_preferred field
to identify which cpus can be paused. 1 means can pause, 0 means
the cpu cannot pause.
The output is in order of the number of the cpu. For example
# cat /sys/devices/system/cpu/cpu3/core_ctl/not_preferred
1 0 1 0
This means that cpu 3 and cpu 5 are not_preferred and can be
paused.
