* StartFrameTimeRecording, together with StopFrameTimeRecording
|
|
* enable recording of frame intervals.
|
|
*
|
|
* To allow concurrent consumers, a cyclic array is used which serves all
|
|
* consumers, practically stateless with regard to consumers.
|
|
*
|
|
* To save resources, the buffer is allocated on first call to StartFrameTimeRecording
|
|
* and recording is paused if no consumer which called StartFrameTimeRecording is able
|
|
* to get valid results (because the cyclic buffer was overwritten since that call).
|
|
*
|
|
* To determine availability of the data upon StopFrameTimeRecording:
|
|
* - mRecording.mNextIndex increases on each PostPresent, and never resets.
|
|
* - Cyclic buffer position is realized as mNextIndex % bufferSize.
|
|
* - StartFrameTimeRecording returns mNextIndex. When StopFrameTimeRecording is called,
|
|
* the required start index is passed as an arg, and we're able to calculate the required
|
|
* length. If this length is bigger than bufferSize, it means data was overwritten.
|
|
* otherwise, we can return the entire sequence.
|
|
* - To determine if we need to pause, mLatestStartIndex is updated to mNextIndex
|
|
* on each call to StartFrameTimeRecording. If this index gets overwritten,
|
|
* it means that all earlier start indices obtained via StartFrameTimeRecording
|
|
* were also overwritten, hence, no point in recording, so pause.
|
|
* - mCurrentRunStartIndex indicates the oldest index of the recording after which
|
|
* the recording was not paused. If StopFrameTimeRecording is invoked with a start index
|
|
* older than this, it means that some frames were not recorded, so data is invalid.
