soc: qcom: msm_perf: Detect & notify userspace about heavy CPU loads
Detect single and multi threaded heavy workloads based on loads
received from interactive governor.
- If the max load across all the CPUs is greater than a
user-specified threshold for certain number of governor windows
then the load is detected as a single-threaded workload.
- If the total load across all the CPUs is greater than a
user-specified threshold for certain number of governor windows
then the load is detected as a multi-threaded workload.
If one of these is detected then a notification is sent to the
userspace so that an entity can read the nodes exposed to get an
idea of the nature of workload running.
