Abstract: A failure recommendation system for a command line interface (CLI) uses machine learning to predict the most likely command to correct an unsuccessful or failed attempt to perform an intended operation using the CLI. The failure recommendation system is based on a conditional probability model trained on failure-success pairs of commands from CLI telemetry data to learn the most likely command to remediate a failure. The conditional probability model predicts the most likely command based on a failure type and the failed command. The failure type is identified through a failure type classifier and is used to select the most likely command to remediate a failure from the different events that may lead to a failure.

Abstract: A method for Serial Peripheral Interface (SPI) operating-mode synchronization between an SPI host and an SPI device, which communicate over an SPI bus, includes predefining, in the SPI device, one or more values on the SPI bus as indicative of lack of synchronization of an SPI operating mode between the SPI host and the SPI device. Re-synchronization of the SPI operating mode is initiated in response to receiving any of the predefined values in the SPI device.

Abstract: To reduce software development man-hours when vehicle models are developed an in-vehicle equipment controller includes a CPU and memory. The CPU has, as a software configuration, an application layer, a middleware layer, and a device driver. In the middleware layer, a first communication packet on the application side and a second communication packet on a device driver side are installed. In the middleware layer, a communication path between the application layer and the device driver is generated based on a mapping table stored in the memory.

Abstract: Techniques for intelligently routing IO to a storage class memory (SCM) namespace are disclosed. A configuration for a namespace is determined, where the configuration indicates a type of IO that the namespace is structured to handle. Details about the configuration of the namespace are stored in a repository. A forwarding rule is generated based on the namespace's stored configuration. When incoming IO having attributes similar to that type is received, implementation of the forwarding rule causes the incoming IO to be directed to the namespace. Attributes of a particular incoming IO are determined. As a result of the attributes satisfying a similarity threshold relative to the type, the forwarding rule is implemented such that the particular incoming IO is directed to the namespace.

Abstract: During the development of Low Power Mode (LPM) (also known as L2 Mode) for DSL (Digital Subscriber Line) systems, it has become apparent that one of the most important issues is the impact on deployed legacy DSL systems. Legacy DSL systems are not capable of operating in the presence of large changes in crosstalk noise from neighbouring lines entering and exiting LPMs. For example, prior LPM methods at least do not assure that legacy lines will be protected to guarantee that no retrains will occur. These and other issues are addressed herein.

The CPLD receiving the ID signals detects whether the first and second slimline connectors are in their specified and correct slots. Powering on of computer is not permitted if incorrect connection is found, and a warning prompt is generated. A PCIe channel width for each slimline is automatically configured if no incorrect connection is found. A server applying the method is also disclosed.

Abstract: Examples herein relate to polling for input/output transactions of a network interface or a storage device, or any peripheral device. Some examples monitor clock cycles spent checking for a presence of input/output (I/O) events and processing I/O events and monitor clock cycles spent checking for presence of I/O events without completing an I/O event. Central processing unit (CPU) core utilization can be based on clock cycles spent checking for a presence of I/O events and processing I/O events and clock cycles spent checking for presence of I/O events without completion of an I/O event. For example, if core utilization is below a threshold, frequency of the core can be reduced for performing polling of I/O events. If core utilization is at or above the threshold, frequency of the core can be increased used to performing polling of I/O events.
