Right now, iMX6ULL has support for basic framebuffer with CONFIG_FB_MXS in kernel with driver "drivers/video/fbdev/mxsfb.c" and the compatible driver string "fsl,imx28-lcdif".
Is there any DRM Framebuffer support for iMX6ULL ?
The final goal is to use Qt with DRM Framebuffer platform plugin.
I have tester CONFIG_DRM_MXSFB and driver "drivers/gpu/drm/mxsfb/mxsfb_drv.c" with also the compatible driver string "fsl,imx28-lcdif". But I have errors in the kernel log:
mxsfb_drm 21c8000.lcdif: Failed to initialize drm fb helper.
mxsfb_drm 21c8000.lcdif: Failed to init FB CMA area
and also the kernel crashes afterwards.
