    摘要: A processing device comprises an instruction execution unit, a memory agent and pinning logic to pin memory pages in a multi-level memory system upon request by the memory agent. The pinning logic includes an agent interface module to receive, from the memory agent, a pin request indicating a first memory page in the multi-level memory system, the multi-level memory system comprising a near memory and a far memory. The pinning logic further includes a memory interface module to retrieve the first memory page from the far memory and write the first memory page to the near memory. In addition, the pinning logic also includes a descriptor table management module to mark the first memory page as pinned in the near memory, wherein marking the first memory page as pinned comprises setting a pinning bit corresponding to the first memory page in a cache descriptor table and to prevent the first memory page from being evicted from the near memory when the first memory page is marked as pinned.

    摘要: According to some embodiments, a message generated by a downstream device is received at upstream device. The message may, for example, be received via a peripheral interface and may not require a response. It may then be determined that an error is associated with the message, and an alert message may be sent from the upstream device to the downstream device via the peripheral interface.

    摘要: Machine-readable media, methods, and apparatus are described which order memory transactions to increase utilization of multiple memory channels. In some embodiments, a processor may determine an issue order for memory transactions based on the memory channels that are to service the memory transactions. In some embodiments, the processor attempts to obtain an issue order that minimizes or reduces the number of idle periods experienced by the memory channels. Further, the processor may issue the memory transactions to an external memory controller for servicing in the determined issue order.
