// The |total_active_duration_ns| must be set to the approximate total amount of

// time the GPU spent running work for |uid| within the period, without

// "double-counting" parallel GPU work on the same GPU for the same |uid|. "GPU

// work" should correspond to the "GPU slices" shown in the AGI (Android GPU

// "double-counting" parallel GPU work on the same GPU for the same |uid|. Note

// that even if the parallel GPU work was submitted from several different

// processes (i.e. different PIDs) with the same UID, this overlapping work must

// not be double-counted, as it still came from a single |uid|. "GPU work"

// should correspond to the "GPU slices" shown in the AGI (Android GPU

// Inspector) tool, and so should include work such as fragment and non-fragment

// work/shaders running on the shader cores of the GPU. For example, given the

// following:

// following for a single |uid|:

//  - A period has:

//    - |start_time_ns|: 100,000,000 ns

//    - |end_time_ns|:   800,000,000 ns

//  - from 600,000,000 ns to 700,000,000 ns, giving a duration of 100,000,000 ns

//    (GPU work D)

//

// Thus, the |total_active_duration_ns| is the sum of the (non-overlapping)

// durations. Drivers may not have efficient access to the exact start and end

// times of all GPU work, as shown above, but drivers should try to

// approximate/aggregate the value of |total_active_duration_ns| as accurately

// as possible within the limitations of the hardware, without double-counting

// parallel GPU work for the same |uid|. The |total_active_duration_ns| value

// must be less than or equal to the period duration (|end_time_ns| -

// |start_time_ns|); if the aggregation approach might violate this requirement

// then the driver must clamp |total_active_duration_ns| to be at most the

// period duration.

// Thus, the |total_active_duration_ns| is the sum of these two

// (non-overlapping) durations. Drivers may not have efficient access to the

// exact start and end times of all GPU work, as shown above, but drivers should

// try to approximate/aggregate the value of |total_active_duration_ns| as

// accurately as possible within the limitations of the hardware, without

// double-counting parallel GPU work for the same |uid|. The

// |total_active_duration_ns| value must be less than or equal to the period

// duration (|end_time_ns| - |start_time_ns|); if the aggregation approach might

// violate this requirement then the driver must clamp

// |total_active_duration_ns| to be at most the period duration.

//

// Protected mode: protected GPU work must not be reported. Periods must be

// emitted, and the |total_active_duration_ns| value set, as if the protected

// GPU work did not occur.

//

// Note that the above description allows for a certain amount of flexibility in

// how the driver tracks periods and emits the events. We list a few examples of
