Abstract: A processor includes a memory management unit and a front end including a decoder. The decoder includes logic to receive a flush-on-commit (FoC) instruction to flush dirty data from a volatile cache to a persistent memory upon commitment of a store associated with the FoC instruction. The memory management unit includes logic to, based upon a flush-on-fail (FoF) mode, skip execution of the flush-on-commit instruction and to flush the dirty data from the volatile cache upon a subsequent FoF operation.

Abstract: Implementations of the disclosure provide a processing device comprising an address translation circuit to intercept a work request from an I/O device. The work request comprises a first ASID to map to a work queue. A second ASID of a host is allocated for the first ASID based on the work queue. The second ASID is allocated to at least one of: an ASID register for a dedicated work queue (DWQ) or an ASID translation table for a shared work queue (SWQ). Responsive to receiving a work submission from the SVM client to the I/O device, the first ASID of the application container is translated to the second ASID of the host machine for submission to the I/O device using at least one of: the ASID register for the DWQ or the ASID translation table for the SWQ based on the work queue associated with the I/O device.
