    Abstract: In some embodiments, an apparatus includes logical interrupt identification number creation logic to receive physical processor identification numbers and create logical processor identification numbers through using the physical processor identification numbers. Each of the logical processor identification numbers corresponds to one of the physical processor identification numbers, and the logical processor identification numbers each include a processor cluster identification number and an intra-cluster identification number. The processor cluster identification numbers are each formed to include a group of bits from the corresponding physical processor identification number shifted in position, and the intra-cluster identification numbers are each formed in response to values of others of the bits of the corresponding physical processor identification number. Other embodiments are described.

    Abstract: Methods and apparatus are disclosed for efficient TLB (translation look-aside buffer) shoot-downs for heterogeneous devices sharing virtual memory in a multi-core system. Embodiments of an apparatus for efficient TLB shoot-downs may include a TLB to store virtual address translation entries, and a memory management unit, coupled with the TLB, to maintain PASID (process address space identifier) state entries corresponding to the virtual address translation entries. The PASID state entries may include an active reference state and a lazy-invalidation state. The memory management unit may perform atomic modification of PASID state entries responsive to receiving PASID state update requests from devices in the multi-core system and read the lazy-invalidation state of the PASID state entries. The memory management unit may send PASID state update responses to the devices to synchronize TLB entries prior to activation responsive to the respective lazy-invalidation state.

    Abstract translation: 公开了用于在多核系统中共享虚拟存储器的异构设备的有效TLB（转换后备缓冲器）击穿的方法和装置。 用于有效的TLB击倒的装置的实施例可以包括用于存储虚拟地址转换条目的TLB和与TLB耦合的存储器管理单元，以维护对应于虚拟地址转换条目的PASID（进程地址空间标识符）状态条目 。 PASID状态条目可以包括活动参考状态和惰性无效状态。 响应于从多核系统中的设备接收到PASID状态更新请求并且读取PASID状态条目的惰性无效状态，存储器管理单元可执行PASID状态条目的原子修改。 存储器管理单元可以在响应于相应的惰性无效化状态的激活之前向设备发送PASID状态更新响应以同步TLB条目。
