Address space identifier management in complex input/output virtualization environments

A method comprising:

• receiving, by a processing device, a first workload instruction from a guest application, the first workload instruction comprising a first untranslated address space identifier (ASID) and a first workload for an input/output (I/O) device;
• translating, by the processing device, the first untranslated ASID to a first translated ASID;
• inserting, by the processing device, the first translated ASID into a payload of the first workload instruction;
• and
• providing, by the processing device, the payload to a work queue of the I/O device to execute the first workload based in part on at least one of:
• the first translated ASID or the first untranslated ASID.

A system comprising:

• a hardware input/output (I/O) memory management unit (IOMMU);
• and
• a processing device, operatively coupled to the IOMMU, to:
• receive a first workload instruction from a guest application, the first workload instruction comprising a first untranslated address space identifier (ASID) and a first workload for an input/output (I/O) device;
• translate the first untranslated ASID to a first translated ASID;
• insert the first translated ASID into a payload of the first workload instruction;
• and
• provide the payload to a work queue of the I/O device to execute the first workload based in part on at least one of:
• the first translated ASID or the first untranslated ASID.
