Abstract

The present disclosure describes apparatuses and techniques for tunneling transaction packets. In some aspects a packet is received from a peripheral device via a first data interface of a device. The packet includes an address for resource access and an identifier that identifies the peripheral device or a function thereof. Based on this identifier, it is determined whether the peripheral device is attempting to access an internal resource of the device or a resource of a host device connected to a second data interface of the device. If the peripheral device is attempting to access the resource of the host device, the packet is routed to the host device via the second data interface without modifying the address for resource access. By so doing, the peripheral device can exchange data with the host device without using address translation.
