The AMD Embedded+ platform integrates AMD Ryzen Embedded processors with AMD Versal AI Edge adaptive SoCs on a single PCB [1]. The AMD Ryzen Embedded processor is connected to the Versal AI Edge adaptive SoC via PCIe enabling a tightly coupled heterogeneous compute platform. AMD Embedded+ platform is used for sensor fusion, AI inferencing, industrial networking, control, and visualization. AMD Versal PCI driver, versal-pci, is a host-side PCIe driver for AMD Embedded+ platform running on AMD Ryzen Embedded processor. The versal-pci driver is responsible for the management-plane operations for the AMD Versal AI Edge adaptive SoC, including: - Loading accelerator firmware images - Reset and recovery - Health monitoring The driver is licensed under GPL-2.0. The firmwares are distributed as closed binaries. Please see [1] for more information. Please see [2] for software architecture.
