Abstract:
Embodiment of this disclosure provides a mechanism to extend a workload instruction to include both untranslated and translated address space identifiers (ASIDs). In one embodiment, a processing device comprising a translation manager is provided. The translation manager receives a workload instruction from a guest application. The workload instruction comprises an untranslated (ASID) and a workload for an input/output (I/O) device. The untranslated ASID is translated to a translated ASID. The translated ASID inserted into a payload of the workload instruction. Thereupon, the payload is provided to a work queue of the I/O device to execute the workload based in part on at least one of: the translated ASID or the untranslated ASID.
