This patchset introduces a new Linux Kernel Driver, *versal-pci*, for AMD
Embedded+ platform.
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.
