Display rotation

Hi, we have an i.MX8MM with LVDS.

We had to run several applications on it and we had to rotate the display 180 degrees.

We have tried several canonical approaches but without success.

How can we rotate the display?

Thank you for your reply, but we choose to don't use weston.

Are there a lower level way?

you can try to use GPU 2D to rotate, you can refer to the G2D api from gpu user guide, you can download the user guide from:
