Question: Best Practices for VBlank-Synchronized Frame Display

[githubniko]

I'm working on a low-latency video display system (120fps → 120Hz) and want to implement proper frame synchronization to avoid tearing.

What would be the recommended way to:

1. Synchronize frame presentation with vblank events?
2. Maintain consistent end-to-end latency?
3. Leverage Rockchip-specific features for synchronization?

Are there any existing synchronization mechanisms in the codebase that I should be using, or is this something that needs to be implemented?
