I want to use the drm framework to implement lvds display on imx6q-sabresd board. I tried L4.9.88 and found that there are many things that need to be changed. I visually inspected L4.19.35 and it seems to use FBDEV too.
So, which version of the Yocto kernel used DRM?
The Direct Render Model (DRM) feature is not supported for the i.MX6 series processors. It is only supported for the i.MX8, i.MX8X and i.MX8M processor families starting from the 4.9.123 kernel.
Best Regards,
Artur
