Abstract: Examples described herein relate to circuitry configured to generate at least one virtual device interface to utilize the processor circuitry and provide the at least one virtual device interface to a server to assign to a process to provide the process with capability to utilize the processor circuitry. In some examples, the processor circuitry is to perform one or more of local area network access, cryptographic processing, and/or storage access. In some examples, the storage access comprises access to one or more Non-volatile Memory Express (NVMe) devices.

Abstract: As described herein, for a selected process identifier and virtual address, a page fault arising from multiple sources can be solved by a one-time operation. The selected process identifier can include a virtual function (VF) identifier or process address space identifier (PASID). In some examples, solving a page fault arising from multiple sources by a one-time operation comprises invoking a page fault handler to determine an address translation.

Abstract: Examples described herein relate to a packet processing device that includes circuitry to receive an address translation for a virtual to physical address prior to receipt of a GPUDirect remote direct memory access (RDMA) operation, wherein the address translation is provided at initiation of a process executed by a host system and circuitry to apply the address translation for a received GPUDirect RDMA operation.
