Abstract: Methods, systems, and devices for using a backup capacitor as an alternate energy source via dynamic APL budgeting are described. A memory system may use excess power available at an energy storage device such as a backup capacitor to improve performance under various circumstances. The amount of power reserved for the APL may be dynamically determined based on various conditions of the memory system. The energy reserved for APL recovery may be dynamically budgeted so that excess energy from the energy storage device may be used to improve operations. The energy storage device may be recharged using surplus power when the amount of energy required for operations at the SSD is less than the maximum power budget for the SSD.

Abstract: Applications are executed on a host in association with a power profile and a pool of one or more CPUs that are isolated relative to the applications. The power profile includes a lowest power state that is suitable for the applications and achieves required performance for the workload being performed by the applications.

Other components, such as the operating system and one or more agents of one or more orchestrators may be allocated their own isolated pool of CPUs operating at a highest power state. The implementation of isolated CPUs that are shared by multiple applications may be performed by an agent of an orchestrator that is called as the CRI when instantiating containers.

Abstract: Systems and methods are provided for implementing mobile connectivity device wake detection and diagnosis.

The determined cause of awakening of the mobile connectivity device includes one of a control path reason, a firmware-based reason, a data path reason, or a peripheral component interconnect (“PCI”) bus-based reason. Based on each of these determined causes of awakening of the mobile connectivity device, a corresponding report (e.g., a control path wake reason report, a firmware-based wake reason report, a data path wake reason report, or a PCI bus-based wake reason report) is sent for further action (e.g., analysis of the wake reasons for subsequent system updates or patches to address the underlying issues associated with the wake reasons).
