Abstract: In one embodiment, a system includes a non-volatile memory that may serve as both the main memory system and the backing store (or persistent storage). In some embodiments, the non-volatile memory is divided into a main memory portion and a persistent portion. Data in the main memory operation may be encrypted using one or more first keys, and data in the persistent portion may be encrypted using one or more second keys, in an embodiment. The volatile behavior of main memory may be implemented by discarding the one or more first keys in a power down event or other event that indicates a loss of main memory data, while the one or more second keys may be retained. In one embodiment, the physical address space of the non-volatile memory may be a mapping from a second physical address space that is used within the system.

Abstract translation: 在一个实施例中，系统包括可用作主存储器系统和后备存储器（或持久存储器）两者的非易失性存储器。 在一些实施例中，非易失性存储器被分成主存储器部分和持久部分。 在一个实施例中，主存储器操作中的数据可以使用一个或多个第一密钥加密，并且持久部分中的数据可以使用一个或多个第二密钥进行加密。 主存储器的易失性行为可以通过在功率下降事件中丢弃一个或多个第一密钥或指示主存储器数据丢失的其他事件来实现，同时可以保留一个或多个第二密钥。 在一个实施例中，非易失性存储器的物理地址空间可以是来自在系统内使用的第二物理地址空间的映射。

Abstract: Embodiments described herein enable the interoperability between processes configured for pointer authentication and processes that are not configured for pointer authentication. Enabling the interoperability between such processes enables essential libraries, such as system libraries, to be compiled with pointer authentication, while enabling those libraries to still be used by processes that have not yet been compiled or configured to use pointer authentication.
