Restricting peripheral device protocols in confidential compute architectures, the method including: receiving a first address translation request from a peripheral device supporting a first protocol, wherein the first protocol supports cache coherency between the peripheral device and a processor cache; determining that a confidential compute architecture is enabled; and providing, in response to the first address translation request, a response including an indication to the peripheral device to not use the first protocol.

A memory module comprises a volatile memory subsystem, a non-volatile memory subsystem, and a module controller coupled to the volatile memory subsystem and to the non-volatile memory subsystem. The module controller is configurable to control data transfers between the volatile memory subsystem and the non-volatile memory subsystem. The module controller includes a data selection circuit configurable to pre-search data transferred from the non-volatile memory with respect to one or more search criteria before providing the pre-select data relevant to the one or more search criteria to the volatile memory subsystem.

Example approaches for processing task deployment in adapter devices and accelerators, are described. In an example, a service request is received by an adapter device. The service request is indicative of a service associated with a virtual multi-layer network switch. An accelerator may be integrated to the adapter device or coupled to the adapter device. A set of processing tasks associated with the service is identified based on the service request. A processing task instance corresponding to at least one of the set of processing tasks is deployed in one of the adapter device and the accelerator, based on predefined configuration information. The predefined configuration information includes policies for executing each of the set processing tasks in one of the adapter device and the accelerator.

A storage system controller chip includes routing circuitry comprising a host interface for coupling to a host device and an extension interface for coupling to a secondary controller chip. A host controller is coupled to a logical interface of the routing circuitry for receiving a host data access command from the host device via the host interface and logical interface. The routing circuitry transfers the host data access command to the secondary controller chip via the extension interface. The storage system controller chip further includes processor circuitry coupled to the logical interface of the routing circuitry. The processor circuitry receives an indication from the secondary controller chip via the extension interface that execution of the host data access command has been completed by the secondary controller chip and instructs the host controller to notify the host device that execution of the host data access command has been completed.

The invention relates to a system and a method for adapting a response provided by a first device. The system comprises the first device with means for receiving from at least one client device, as at least one second device, a data access request comprising at least one client identifier and a predetermined application programming interface or service provider interface associated with the first device. The first device comprises means for processing the data access request that provides the response to the data access request and means for sending the response. The system comprises adapting means for intercepting and adapting the response sent by the first device. The adapting means adapts the response while being specific to the client and provides an adapted response. And the system comprises adapted response sending means for sending at least a part of the adapted response to the second or a third device(s).

A method of provisioning a system includes defining one or more virtual peripherals such that each of the virtual peripherals corresponds to a respective device; identifying one or more enabled virtual peripherals; and identifying one or more control modules. Each of the control modules includes one or more terminals for connecting to one or more devices. The method further includes linking each of the enabled virtual peripherals to a respective terminal of the one or more control modules to form a link; generating a provisioning configuration that represents the link between the respective terminal and the corresponding one of the enabled virtual peripherals; and writing the provisioning configuration to each of the control modules. The method further includes connecting the respective device to the respective terminal consistent with the link between the respective terminal and the corresponding one of the enabled virtual peripherals.

There is provided a communication apparatus comprising a connector that includes a plurality of signal lines and connects to an external recording device. The control unit performs control to determine whether a second signal has been input before a predetermined time period elapses since a first signal was output to the external recording device, the second signal indicating that the external recording device is compatible with a second transfer mode. In a case where it is determined that the second signal has been input, the control unit performs control to perform communication in the second transfer mode.

Multiple independent endpoint devices can be emulated using a single system on chip (SoC) device. Such a SoC can have multiple cores that can emulate ports according to a specified protocol, such as the peripheral component interconnect express (PCIe) protocol useful for data communications. An emulation agent can manage various aspects of these emulated endpoint devices in software, including serving interrupts for relevant emulated devices according to a determined priority scheme. Interrupts can be registered for each device, and data structures allocated dynamically for a determined number and type(s) of PCIe endpoint devices to be emulated. Each PCIe core on the SoC can function as a separate PCIe endpoint device endpoint for communicating with one or more hosts or other such devices.
