Definition at line 35 of file Utils.h.

    PERMISSION_SYSTEM, 
    PERMISSION_THIRD_PARTY, 
    NUMBER_PERMISSIONS 
};

Policy

enum Policy

Different Resource Policies supported by Resource Tuner.

Resource Policies determine the order in which the Tuning Requests will be processed for a particular resource. Currently 4 types of Policies are supported:

Enumerator
INSTANT_APPLY	This policy is for resources where the latest request needs to be honored.
HIGHER_BETTER	This policy first applies the request writing the highest value to the node.
LOWER_BETTER	Self-explanatory. Works exactly opposite of the higher is better policy.
LAZY_APPLY	The requests are applied in a first-in-first-out manner.

Definition at line 61 of file Utils.h.

            {
    INSTANT_APPLY, 
    HIGHER_BETTER, 
    LOWER_BETTER, 
    LAZY_APPLY 
};

PriorityLevel

enum PriorityLevel

Resource Tuner Priority Levels.

Each Request will have a priority level. This is used to determine the order in which requests are processed for a specific Resource. The Requests with higher Priority will be prioritized.

Definition at line 47 of file Utils.h.

                   {
    SYSTEM_HIGH = 0, // Highest Level of Priority
    SYSTEM_LOW,
    THIRD_PARTY_HIGH,
    THIRD_PARTY_LOW,
    TOTAL_PRIORITIES
};
