Missing Features, Known Issues and Limitations in the driver

• No tool flow support for Bitstream Bitstream loading using Overlay (DTG, Petalinux and Yocto)
  

Note 1: The descriptions in subsequent sections refer to use of Device Tree Overlay (DTO) fragments with FPGA manager framework. It has to be noted that the generation of DTO fragments are not supported in official Xilinx Petalinux release. 
              

Note 2: Axi Interrupt controller driver doesn't work as kernel modules/overlay like other device drivers due to the below limitation

                    Interrupt controller driver uses to register with . So it will follow the below sequence to invoke the xilinx_intc_of_init) (callback function)

                           start_kernel) –> init_IRQ) --> irqchip_init) --> of_irq_init) --> call-back functionxilinx_intc_of_init)

                   If The Driver was registered using IRQCHIP_DECLARE  it must be compiled into the kernel and the callback function will be invoked at kernel boot time.

Kernel Configuration

The following config options to be enabled in order to use FPGA Manager, Please note that these options are enabled by default  through xilinx_versal_defconfig except for the option. If user wants to test feature they have it.
