Abstract

Disclosed herein are systems and methods for isolating input/output computing resources. In some embodiments, a host device may include a processor and logic coupled with the processor, to identify a tag identifier (Tag ID) for a process or container of the host device. The Tag ID may identify a queue pair of a hardware device of the host device for an outbound transaction from the processor to the hardware device, to be conducted by the process or container. Logic may further map the Tag ID to a Process Address Space Identifier (PASID) associated with an inbound transaction from the hardware device to the processor that used the identified queue pair. The process or container may use the PASID to conduct the outbound transaction via the identified queue pair. Other embodiments may be disclosed and/or claimed.
