Questions on developing an application for Xilinx Zynq® UltraScale+™ ZU15EG


I have some questions on developing an GUI application for ADM-VPX3-9Z2 board which uses Xilinx Zynq® UltraScale+™ ZU15EG as a target device:

1) Are there any particular compiler options such as mcpu, mtune, mfpu,etc that might be needed for Zynq processors?

2) I am using Yocto meta-xilinx layer (https://github.com/xilinx/meta-xilinx.git branch: rel-v2017.4 as required by Alpha Data meta layer(https://github.com/adps/meta-adlnx/tree/admvpx39z2) to build Yocto image and toolchain for the board

   - Is there a newer version available for the meta-xilinx layer?

   - For graphics libraries, my understanding is as follows:

     mesa-gl provides GLX support 

     libmali-xlnx provides GLES support. I would like to understand more details about the graphics libraries provided under the x11 and fbdev directories. What are the differences between the libraries under the two directories and how should they be used? For Xilinx Zynq® UltraScale+™ ZU15EG, What is recommended to be used to get best performance: X11 or fbdev?

 Thank you for the help.
