Targeted memory pressure event notifications
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.
