Question about FrameTimeline in Perfectto

[Dopezhi]

Recently, I am studying the implementation principle of FrameTimeline in Perfectto. I have read the relevant content of the https://perfetto.dev/docs/data-sources/frametimeline document, which only introduces some basic definitions and how to judge by observing FrameTimeline Whether jank. I want to know the implementation principle of FrameTimeline in the SurfaceFlinger source code. Do you have relevant documents or change links?

I'm not available of any documentation beyond what is available at https://perfetto.dev/docs/data-sources/frametimeline

You can always look at the actual code emitting these events. This is available at https://cs.android.com/android/platform/superproject/+/master:frameworks/native/services/surfaceflinger/FrameTimeline/FrameTimeline.h;l=143?q=f:surfaceflinger%20frametimeline
