Abstract

A combined data processing unit (DPU) and server solution with DPU operating system (OS) integration is described. A DPU OS is executed on a DPU or other computing device, where the DPU OS exercises secure calls provided by a DPU's trusted firmware component, that may be invoked by DPU OS components to abstract DPU vendor-specific and server vendor-specific integration details. An invocation of one of the secure calls made on the DPU to communicate with its associated server computing device is identified. In an instance in which the one of the secure calls is invoked, the secure call invoked is translated into a call or request specific to an architecture of the server computing device and the call is performed, which may include sending a signal to the server computing device in a format interpretable by the server computing device.
