    摘要: An embodiment may include circuitry to select, at least in part, from a plurality of memories, at least one memory to store data. The memories may be associated with respective processor cores. The circuitry may select, at least in part, the at least one memory based at least in part upon whether the data is included in at least one page that spans multiple memory lines that is to be processed by at least one of the processor cores. If the data is included in the at least one page, the circuitry may select, at least in part, the at least one memory, such that the at least one memory is proximate to the at least one of the processor cores. Many alternatives, variations, and modifications are possible.

    摘要: In one embodiment, a cache memory includes entries each to store a ring level identifier, which may indicate a privilege level of information stored in the entry. This identifier may be used in performing read accesses to the cache memory. As an example, a logic coupled to the cache memory may filter an access to one or more ways of a selected set of the cache memory based at least in part on a current privilege level of a processor and the ring level identifier of the one or more ways. Other embodiments are described and claimed.

    摘要: In one embodiment, the present invention includes a page fault handler to create page table entries and TLB entries in response to a page fault, the page fault handler to determine if a page fault resulted from a stack access, to create a superpage table entry if the page fault did result from a stack access, and to create a TLB entry for the superpage. Other embodiments are described and claimed.

    摘要: In one embodiment, the present invention includes a method for handling a registration message received from a host processor, where the registration message delegates a poll operation with respect to a device from the host processor to another component. Information from the message may be stored in a poll table, and the component may send a read request to poll the device and report a result of the poll to the host processor based on a state of the device. Other embodiments are described and claimed.
