Devices, methods, and systems for secure communications on a computing device. A host operating system (OS) runs on a host processor in communication with a host memory. A secure OS runs on a coprocessor in communication with a secure memory. The coprocessor receives information from an external device over a secure peer-to-peer (P2P) connection. The secure P2P connection is managed by the secure OS and is not accessible by the host OS.

A computer system, remote control monitoring system, and remote control monitoring method are provided to instantly provide the local display screen of the local computer to the remote computer for remote real-time display. The remote control monitoring system is arranged in the local computer and has a signal receiver and a remote controller. The signal receiver receives the video signal from the processor, executes the signal transforming process to generate the video signal in different standards. The remote controller executes a network compressing process on the transformed video signal to generate the network transportable video data, and transmits the data to the remote computer for displaying the corresponding remote display screen on the remote computer. The present disclosure enables the implementing of the out-of-band remote displaying.

Aspects include receiving, at an input/output (I/O) processor, a transport control word (TCW) that includes an instruction to perform physical port mirroring. It is identified, by the I/O processor, a first port to be mirrored and a second port to perform the mirroring. The second port is a physical port on a host bus adapter (HBA). In response to outbound data being sent to the first port for transmission to a first target device and to the instruction specifying outbound port mirroring, the I/O processor sends a copy of the outbound data to a second target device via the second port. In response to receiving inbound data at the first port and to the instruction specifying inbound port mirroring, a copy of the inbound data is transmitted to the second target device via the second port.

The present invention provides a storage device including a controller and methods for operating the storage device and the controller. A controller of a storage device may comprise: an interface controller; a memory controller; a processor configured to transmit downstream commands and upstream commands to the memory controller. The memory controller may be coupled between the interface controller and the processor and may comprise: a first command queue; a second command queue; and a racing handler. The memory controller may be configured to: store a first command received from the processor in the first command queue; transmit, to the interface controller, first information associated with the first command; store a second command received from the processor in the second command queue; transmit, to the interface controller, second information associated with the second command; and in response to a second access region of the second command overlapping a first access region of the first command, assign a second serial number for the second command based on a first serial number for the first command by the racing handler.

A storage device includes a main non-volatile memory and a controller communicating with a host according to a predetermined interface protocol and controlling the main non-volatile memory. The controller includes a special function register (SFR) storing parameters indicating connection characteristics between the storage device and the host. The controller receives a parameter change command according to the interface protocol from the host, extracts one or more descriptors respectively including an SFR address and a parameter value corresponding to a target parameter to be changed from the parameter change command, and tunes an interface by executing the one or more descriptors to write the parameter value into the SFR.

A system can include a plurality of sequencers each configured to provide a number of sequenced output signals responsive to assertion of a respective sequencer enable signal provided thereto. The system can include chaining circuitry coupled to the plurality of sequencers. The chaining circuitry can comprise logic to: responsive to assertion of a primary enable signal received thereby, assert respective sequencer enable signals provided to the plurality of sequencers in accordance with a first sequence; and responsive to deassertion of the primary enable signal, assert the respective sequencer enable signals provided to the plurality of sequencers in accordance with a second sequence.

Access to peripherals can be managed in a containerized environment. A management service can be employed on a computing device to detect when a container is created. When a container is created or a peripheral is connected, the management service can determine that an application running within the container should be allowed to access a peripheral. The management service can then interface with a peripheral mapper running within the container to enable the application to access the peripheral. A peripheral access manager can also be employed to isolate the peripheral to the container.

A device, includes an instruction buffer. The instruction buffer is configured to store instructions related to at least a portion of a data stream to be analyzed by a state machine engine as the device. The state machine engine includes configurable elements configured to analyze the at least a portion of a data stream and to selectively output the result of the analysis. Additionally, the instruction buffer is configured to receive the indications as part of a direct memory access (DMA) transfer.

Certain embodiments herein relate to pairing an external device and a computer using a random user action. The random user action may be generated based on the type of device. After an external device is connected to the computer, the external device is segregated from one or more resources of the computer. A random user action based on the device type, and to be received from the external device, is generated and requested. If the random user action is received, the external device is paired with the computer and provided access to the one or more resources of the computer.

An expander I/O module discovery/management system includes a secondary system chassis housing an expander I/O module coupled to a server device. The server device identifies the secondary system chassis and an expander I/O module port utilized by that server device, and then generates and transmits an expander I/O module reporting communication identifying the secondary system chassis and the expander I/O module port. A primary system chassis houses a switching I/O module coupled to the expander I/O module. The switching I/O module receives the expander I/O module reporting communication and determines that the secondary system chassis identified in the expander I/O module reporting communication is different than the primary system chassis. In response, the switching I/O module assigns a virtual slot to the expander I/O module, and assigns a virtual port associated with the virtual slot to the expander I/O module port identified in the expander I/O module reporting communication.
