Abstract: This document describes systems and techniques for a hardware-based save-and-restore controller in an SoC. The described systems and techniques can automatically save and restore access control configurations (e.g., register states) of IP subsystems during a power-down and a power-up sequence, respectively. The save operation is initiated by a local save-and-restore (L SAR) controller and performed by the IP subsystems writing the configuration values to a central save-and-restore (C-SAR) controller before powering down a power domain. The C-SAR controller saves the configuration information in a memory located in an always-on power domain. The described systems and techniques initiate, via the L SAR controller, a restore operation as part of the power-up sequence. In this way, the described systems and techniques provide scalable save-and-restore services, support a large number of power domains, and allow a variable number of access control configurations to be saved and restored.

Abstract: Described herein are methods and a system for placing a network and devices in life support when it is determined that a network event necessitates such. Interconnected devices on the network are monitored, devices providing status such as temperature. Based on status, a life support event is determined. If it is determined that life support is needed, devices and services are prioritized. Monitoring is performed as to changes in the network and devices. The network and devices are returned to normal operation if the monitoring determines a normal status.

The processing device is also configured, responsive to determining that the cellular operational profile is provisioned, to establish a connection with the cellular-based management network.

Abstract: A building controller stores a default configuration for a wireless interface. The wireless interface is configured with the default configuration and the building controller establishes a wireless network connection with a configuration tool via a default wireless access point. The building controller receives an updated configuration from the configuration tool. After receiving the updated configuration, the building controller configures the wireless interface with the updated configuration, and terminates the wireless network connection with the default wireless access point. With the wireless interface configured with the updated wireless configuration, the building controller attempts to establish a wireless network connection via the wireless interface with a remote device using the updated wireless configuration.

Abstract: If a secure element accesses a resource that is separate from the secure element, conducting a secure transaction can be inefficient in terms of power or time. Power usage is inefficient if the resource is never permitted to sleep, and transaction time is inefficient if the resource is permitted to sleep, and the user experiences a delay. To enable dual efficiency, a resource entity is permitted to be powered down. The resource entity is then powered up speculatively by an activation controller. The activation controller predicts an upcoming secure transaction based on sensor output, such as a position fix or a detected electromagnetic field. Based on monitored sensor output, the activation controller issues an activation signal to power up the secure element or the resource entity prior to initiation of the upcoming secure transaction. Thus, power can be conserved without introducing a transaction-processing latency.

Abstract: This document describes a secure element that leverages the resources of a computer system to perform specialized functions using sensitive information. The secure element securely stores sensitive information on flash memory of the computer system. In response to a request requiring use of sensitive information, the secure element loads a security application and sensitive information from the computer system. By leveraging external resources, the secure element may flexibly accommodate increasing resource requirements of the computer system and be used in a wide range of computer systems.

Abstract: This document describes techniques and apparatuses for memory patching with associative and directly mapped patch data. In some aspects, a processor requests boot code stored at an address of a first region of an address map of a boot ROM. A boot ROM controller can determine, based on the address, that an associative record in a programmable memory includes address information matching the address. The controller returns patch data of the associative record. This patch data includes another address to a second region of the address map. The processor requests other data of the other address, which is directly mapped to other records of the programmable memory that do not include address information related to the address map. Based on an offset between the start address of the second region and the other address from which data is requested, the other data can be fetched from the directly mapped record.

Abstract: Current data center deployments, particularly layer 2 (L2) deployments that use multi-chassis link aggregation group (MC-LAG) implementations, have limitations. Such deployments use a link, known as an inter-node link (INL)/inter-chassis link (ICL), to connect peer information handling system nodes. Because the peer nodes are coupled together via one or more INL connections, there are fewer ports available for each peer node to connect to end nodes. This configuration creates limitations to bandwidth and scaling, and also increase costs. Embodiments herein allow for the elimination of INLs by moving forwarding decisions to the spine node level. In one or more embodiments, a spine node determines ports to reach dual-homed, single-homed, and orphaned node that are connected to leaf node(s) based on information learned from the leaf nodes. For a leaf node, a sub-LAG (link aggregation group) may be created to reach single-homed/orphaned nodes connected to the leaf node.

The server is further configured to define a distinguished causal mapping between the one or more thermal features and the one or more behavior profiles and determine one or more corrective actions for each of the plurality of self-executing defrost failure instances associated with one or more refrigeration units based on the distinguished causal mapping.
