The Linux PCI endpoint framework enables Linux to operate as a PCIe Endpoint device by interacting with hardware. It provides functions for describing PCIe configuration space content and transferring data via the PCIe bus. However, testing the framework and its implementations can be challenging due to the limited availability of real PCIe endpoint hardware for testing purposes. To address this limitation, we are proposing a virtual device that allows the PCIe endpoint framework to function without relying on physical hardware. This virtual device can improve the testability, leading to more robust and reliable implementations. In this session, we will introduce the design and implementation of this virtual device.
