IPU and dual framebuffer support in imx8

[abrahamlincoln]

Hi,

We are using imx6 dual core and we are planning to migrate to imx8qm from imx6 dual 

We are using dual framebuffer for our application development. 

1. Framebuffer 0 -  we run native OpenGL application to fixed resolution (/dev/fb0)
2. Framebuffer 1 - we run QT application without GPU acceleration (/dev/fb1)

We use IPU to blend above framebuffer to single frame and render to LVDS. 

We would like to follow same approach in imx8qm, documentation says that imx8 does not support dual framebuffer and IPU. 

Any ideas to recreate same architecture in imx8 ?

Thanks,

Abu

@joanxie  Thanks for your confirmation

i.mx8qm is totally different from imx6d, and imx8qm doesn't support framebuffer driver anymore, if you need to set dual display, you can use the default demo images to test first, it's not easy to migrate from imx6d directly
