  • Capability based locking and access of shared persistent memory
    Patent number: 10628057
    Abstract: An example computing system may include a plurality of processors, persistent memory that is shared by the plurality of processors, and a memory-side accelerator that is to control access to the memory. A requesting processor of the plurality of processors may simultaneously request locking of and access to a target data object of the persistent memory by sending a single lock-and-access message to the memory-side accelerator. The lock-and-access message may include a first memory capability pointing to the target data object, a second memory capability pointing to a lock object that controls locking of the target data object, and a specified access operation that is requested.

  • Memory system and handles to master capabilities
    Patent number: 10387335
    Abstract: In one example, a processor sends a memory access request including a data capability and a handle which references a master capability. In response to receiving the memory access request, a memory controller checks whether the handle references a valid master capability and checks whether the data capability is within a scope of the master capability. In response to determining that the master capability is valid and the data capability is within the scope of the master capability, the memory controller returns a result of the memory access request to the processor.
