How does imx6q implement multiple layers

[864535720]

Hello,
The development board I use is imx6qsabresd. I use HIDMI to display my program UI. Does the imx6q HDMI output support multiple layers? If it supports multiple layers, how do I configure it?

Hello, the multi-layer I am talking about here refers to overlay.
HDMI does not support multiple layers, does LVDS support?
Is there a demo that stacks two framebuffers together?
