Overview


Xen is a type-1 Hypervisor defined, maintained and provided to the open source community by the Xen Project. Xilinx actively contributes code to the Xen Project to provide Zynq UltraScale+ MPSoC platform support as well as key enhancements which benefit Xilinx customer use-cases.

Xen allows multiple instances of operating system(s) or bare-metal applications to execute on Zynq UltraScale+ MPSoC. Additional information on the Xen hypervisor can be found at the Xen Project Getting Started page.

Xilinx provides within the PetaLinux Tools and also in our Git tree, core elements and example designs to enable usage of Linux + bare-metal system configurations across the processing cores of Zynq UltraScale+ MPSoC. Key components of these example designs are described below in order to assist our customers to configure, build and deploy these basic configurations and to also identify current functionality gaps which may need to be further addressed within the customer's final system architecture.
