Abstract: A system comprises a number of master devices and an interconnect for managing coherency between the master devices. In response to a read-with-overridable-invalidate transaction received by the interconnect from a requesting master device requesting that target data associated with a target address is provided to the requesting master device, when target data associated with the target address is stored by a cache, the interconnect issues a snoop request to said cache triggering invalidation of the target data from the cache except when the interconnect or cache determines to override the invalidation and retain the target data in the cache. This enables greater efficiency in cache usage since data which the requesting master considers is unlikely to be needed again can be invalidated from caches located outside the master device itself.

Abstract: Presented herein are methods of replicating versioned and hierarchical data structures, as well as data structures representing complex transactions. Due to interdependencies between data entities and a lack of guaranteed message ordering, simple replication methods employed for simple data types cannot be used. Operations on data structures exhibit dependencies between the messages making up the operations. This strategy can be extended to various types of complex transactions by considering certain messages to depend on other messages or on the existence of other entries at the data store. Regardless of origin, these dependencies can be enforced by suspending the processing of messages with unsatisfied dependencies until all of its dependencies have been met. Alternately, transactions can be committed immediately, creating entities that include versioned identifiers for each of their dependencies. These entities can then be garbage collected of the parent objects are not subsequently created.

Abstract: A vendor extension command is used to transport a proprietary message to a device (e.g., a solid state drive), to instruct the device to access and return data stored on the device (e.g., data that can be used for debugging). More specifically, a device that is coupled to a host system by a host bus interface (e.g., a Peripheral Component Interconnect Express bus) receives a command in a vendor extension of a standard driver (e.g., a Non-Volatile Memory Express driver). In response to the command in the vendor extension, data (e.g., debugging data) stored in memory on the device is accessed. The data can then be sent over the host bus interface to the host system. Thus, for example, a proprietary debugging framework can be used with a standards-based device.
