Patent number: 11934321Abstract: A memory management method is provided, which includes assigning separate virtual addresses to processes in user space, include to a file system configured to read/write to persistent storage. Virtual memory objects (VMOs) are created in user space that are backed by a user space pager service. Such objects including pages representing a file associated with information maintained in persistent storage. A pager manages reading/writing to persistent storage. The pager populates pages for a given VMO using data retrieved from persistent storage. Upon populating the pages, a state of the VMO is set to a clean state. Upon writing to the pages, the state of the VMO is set to a dirty state. Upon initiating writing back to persistent storage, the state of the VMO is set to an awaiting clean state. Upon ending the writing back, the state of the VMO is set to clean.Type: GrantFiled: August 10, 2022Date of Patent: March 19, 2024Assignee: GOOGLE LLCInventors: Rasha Eqbal, Adrian Danis, Christopher James Suter

Patent number: 11720368Abstract: 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.Type: GrantFiled: March 8, 2021Date of Patent: August 8, 2023Assignee: APPLE INC.Inventors: Andrew D. Myrick, David M. Chan, Jonathan R. Reeves, Jeffrey D. Curless, Lionel D. Desai, James C. McIlree, Karen A. Crippes, Rasha Eqbal
