The DTSI file is provided for you. Copy the uio-system-user.dtsi file to the PetaLinux project.

cp uio-system-user.dtsi build/vck190_petalinux/project-spec/meta-user/recipes-bsp/device-tree/files/system-user.dtsi

This is a user-modifiable PetaLinux device tree configuration file. Open the uio-system-user.dtsi. This file creates a generic-uio driver for each PL kernel instance (dlbf_data_00, dlbf_data_01, dblf_coeff_00, and so on). With this device tree configuration, communicate to the memory addresses of the PL kernels through these UIO drivers without actually knowing the physical addresses.
