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 processing device comprising: an interrupt managing circuit to receive an interrupt message directed to an application container from an assignable interface (AI) of an input/output (I/O) device. The interrupt message comprises an address space identifier (ASID), an interrupt handle and a flag to distinguish the interrupt message from a direct memory access (DMA) message. Responsive to receiving the interrupt message, a data structure associated with the interrupt managing circuit is identified. An interrupt entry from the data structure is selected based on the interrupt handle. It is determined that the ASID associated with the interrupt message matches an ASID in the interrupt entry. Thereupon, an interrupt in the interrupt entry is forwarded to the application container.

Abstract: Aspects of the embodiments are directed to systems and methods for providing and using hints in data packets to perform memory transaction optimization processes prior to receiving one or more data packets that rely on memory transactions. The systems and methods can include receiving, from a device connected to the root complex across a PCIe-compliant link, a data packet; identifying from the received device a memory transaction hint bit; determining a memory transaction from the memory transaction hint bit; and performing an optimization process based, at least in part, on the determined memory transaction.
