[meta-freescale] Regarding bitbaking for custom board (IMX6Q)with no display, for adding GPU support

[Abhilash Abraham]

Hi Daiane,

                 Thanks for the information.

                 I have one more query. After the GPU processing, I need to
copy the processed frame to user space to send it to remote system. I'm
confused whether I should be calling eglSwapBuffer and read from fb0, fb1
alternately or read from fb0 alone after the buffer swap.


With Warm Regards,
