摘要： Methods and systems are disclosed herein for providing a universal PCIe port. In one example, the same port is configured to accept a PCIe connection as a host or an endpoint symmetrically. Downstream transactions towards an endpoint can be intercepted and a virtual address in the downstream transaction can be translated to a local address using a mapping. The downstream transactions can be forwarded to the endpoint using the local address instead of the virtual address. For endpoints that share the same local address with multiple hosts, a reverse lookup may be provided to determine which one of the hosts a local address corresponds when forwarding upstream transactions. PCIe over Ethernet is provided as one embodiment for allowing remote PCIe endpoints to be associated with a local host transparently.
摘要翻译：本文公开了用于提供通用PCIe端口的方法和系统。在一个示例中，相同的端口被配置为对称地接受作为主机或端点的PCIe连接。可以拦截向端点的下游事务，并且可以使用映射将下游事务中的虚拟地址转换为本地地址。可以使用本地地址而不是虚拟地址将下游事务转发到端点。对于与多个主机共享相同本地地址的端点，可以提供反向查找，以确定在转发上游事务时本地地址对应的主机中哪一个。作为一个实施例，提供PCIe以太网，用于允许远程PCIe端点与本地主机透明地相关联。

摘要： One embodiment provides a system that processes an input/output (I/O) operation associated with a portable storage device. During operation, the system loads a virtual computing environment stored on the portable storage device into a host computer system coupled to the portable storage device. Next, the system intercepts the I/O operation from the virtual computing environment to the portable storage device. Finally, the system decouples the I/O operation from the virtual computing environment by processing the I/O operation independently of a representation of the I/O operation in the virtual computing environment.
