Abstract: In general, this disclosure describes techniques that allow communication between devices/modules of a computer system regarding inter-device/module command execution. In accordance with the techniques described herein, an operating device of a computing system may receive from a client one or more command indications of commands to be executed on the operating device. The operating device may further receive at least one command completion indicator that indicates a command for which one or more clients are awaiting completion of execution. The operating device may generate an interrupt that indicates completion of execution of the command for which the at least one command completion indicator was received. The interrupt may be a generic interrupt or a client-specific interrupt. In this manner, inefficiencies caused by client monitoring of operating device command execution may be reduced.

Abstract: Instructions involving a relatively significant data transfer or a particular type of data transfer via a cache result in the application of a restricted access policy to control access to one or more partitions of the cache so as to reduce or prevent the overwriting of data that is expected to be subsequently used by the cache or by a processor. A processor or other system component may assert a signal which is utilized to select between one or more access policies and the selected access policy then may be applied to control access to one or more ways of the cache during the data transfer operation associated with the instruction. The access policy typically represents an access restriction to particular cache partitions, such as a restriction to one or more particular cache ways or one or more particular cache lines.

Abstract: A user management interface for interaction, monitoring and control of an EAS system. A user accessible input is provided in the interface for actuation by a user. A generation assembly is responsive to the input and generates signals for interacting with the EAS system. A receiver at the interface receives signals from the EAS system and provides indications with respect thereto.
