Does TX2 R28.1 support double framebuffer?

I got video frame tearing issue when write image data to /dev/fb0.

I try to call FBIO_WAITFORVSYNC,but image still tearing. And when try to use double framebuffer, I can only see images one frame at one second, looks like FBIOPAN_DISPLAY caused blocking.

I need help…


There is a known issue on tx2 FBIOPAN_DISPLAY that would take much more time.

However, according to your other posts on forum. I would still suggest you to use EGL renderer or DRM renderer in mmapi sample which we guarantee there would be no tearing.
