Abstract: In one embodiment, when a secondary application on an electronic device is selected for deactivation, the memory associated with the application can be gathered, compacted and compressed into a memory freezer file. The memory freezer file can be stored in non-volatile memory with a reduced storage footprint compared to a memory stored in a conventional swap file. When the selected application is to be reactivated, the compressed memory in the memory freezer file can be quickly restored to process memory.

Abstract: Systems, methods, and computer program products for target memory pressure event notifications are disclosed. Processes running on a device can register to receive memory pressure event notifications from a memory management system, which are sent while memory pages are being reclaimed. Active processes running on a device processor can be assigned a priority that ranges from low to high. Responsive to a memory pressure event occurring on the device, the memory management system determines whether less than a threshold number of high priority processes are active on the device. If so, the memory management system sends a memory pressure event notification to the registered process with the lowest priority among the active processes.

Abstract: A method and apparatus of a device for resource management by using a hierarchy of resource management techniques with dynamic resource policies is described. The device terminates several misbehaving application programs when available memory on the device is running low. Each of those misbehaving application programs consumes more memory space than a memory consumption limit assigned to the application program. If available memory on the device is still low after terminating those misbehaving application programs, the device further sends memory pressure notifications to all application programs. If available memory on the device is still running low after sending the memory pressure notifications, the device further terminates background, idle, and suspended application programs. The device further terminates foreground application programs when available memory on the device is still low after terminating the background, idle, and suspended application programs.

Abstract: Techniques for memory management of a data processing system are described herein. According to one embodiment, a memory usage monitor executed by a processor of a data processing system monitors memory usages of groups of programs running within a memory of the data processing system. In response to determining that a first memory usage of a first group of the programs exceeds a first predetermined threshold, a user level reboot is performed in which one or more applications running within a user space of an operating system of the data processing system are terminated and relaunched. In response to determining that a second memory usage of a second group of the programs exceeds a second predetermined threshold, a system level reboot is performed in which one or more system components running within a kernel space of the operating system are terminated and relaunched.

Abstract: Memory management in a data processing system can learn one or more behaviors of software processes such as daemon software processes and application processes, and based on information learned about the behaviors, the memory management can adjust how it controls memory usage in the system. For example, a memory management system can learn how software processes react (e.g. how quickly they relaunch) to memory recovery methods, such as system initiated terminations of one or more software processes that are performed to reclaim memory to increase available volatile memory, and based on information about how they react, the memory recovery methods can operate differently depending upon how the software reacted previously.
