Abstract: Techniques for implementing operating system layering are described herein. In one example, a method includes managing one or more container temporary storage spaces and one or more container runtime environments. Furthermore, the method includes loading, one or more drivers to provide compatibility between a container operating system and a host operating system, the one or more drivers comprising application program interface (API) compatibility libraries to enable API compatibility between the container operating system and the host operating system; metadata arbitration logic to enable compatibility between the container operating system and the host operating system by modifying container operating system references; and file arbitration logic to modify operating system file locations accessed by the container operating system and the host operating system.

Abstract: In one embodiment, a memory management system temporarily maintains a memory page at an artificially high priority level. The memory management system may assign an initial priority level to a memory page in a page priority list. The memory management system may change the memory page to a target priority level in the page priority list after a protection period has expired.

Abstract: A memory manager in a computing device allocates memory to programs running on the computing device, the amount of memory allocated to a program being a memory commit for the program. When a program is in a state where the program can be terminated, the content of the memory pages allocated to the program is compressed, and an amount of the memory commit for the program that can be released is determined. This amount of memory commit is the amount that was committed to the program less any amount still storing (in compressed format) information (e.g., data or instructions) for the program. The determined amount of memory commit is released, allowing that amount of memory to be consumed by other programs as appropriate.

Abstract: A hybrid drive includes multiple parts: a performance part (e.g., a flash memory device) and a base part (e.g., a magnetic or other rotational disk drive). A drive access system, which is typically part of an operating system of a computing device, issues input/output (I/O) commands to the hybrid drive to store data to and retrieve data from the hybrid drive. The drive access system supports multiple priority levels and obtains priority levels for groups of data identified by logical block addresses (LBAs). The LBAs read while the device is operating in a power saving mode are assigned a priority level that is at least the lowest of the multiple priority levels supported by the device, increasing the likelihood that LBAs read while the device is operating in the power saving mode are stored in the performance part of the hybrid drive.

Abstract: Systems and methods of pre-launching applications in a computer system, said applications being likely to be activated by a user from a terminated and/or suspended process state, are disclosed. The pre-launching of an application may be based on the assessed probability of the application being activated—as well as the level of availability of system resources to affect such pre-launching. Applications may be pre-launched based on these and other conditions/considerations, designed to improve the user's experience of a quick launch of applications in the background. Several prediction models are presented to provide a good estimate of the likelihood of an application being activated by a user. Such prediction models may comprise an adaptive predictor (based on past application usage situations) and/or a switch rate predictor (based on historic data of an application being switched and, possibly, having a decay rate applied to such switch rate measure).

Abstract: A hybrid drive includes multiple parts: a performance part (e.g., a flash memory device) and a base part (e.g., a magnetic or other rotational disk drive). A drive access system, which is typically part of an operating system of a computing device, issues input/output (I/O) commands to the hybrid drive to store data to and retrieve data from the hybrid drive. The drive access system assigns, based on various available information, a priority level to groups of data identified by logical block addresses (LBAs). With each I/O command, the drive access system includes an indication of the priority level of the LBA(s) associated with the I/O command. The hybrid drive determines, based on the priority level indications received from the drive access system, which LBAs are stored on which part or parts of the hybrid drive.

Abstract: To ensure that the contents of a non-volatile memory device cache may be relied upon as accurately reflecting data stored on disk storage, it may be determined whether the cache contents and/or disk contents are modified during a power transition, causing cache contents to no longer accurately reflect data stored in disk storage. The cache device may be removable from the computer, and unexpected removal of the cache device may cause cache contents to no longer accurately reflect data stored in disk storage. Cache metadata may be managed during normal operations and across power transitions, ensuring that cache metadata may be efficiently accessed and reliably saved and restored across power transitions. A state of a log used by a file system may be determined prior to and subsequent to reboot of an operating system in order to determine whether data stored on a cache device may be reliably used.

Abstract: Securely redirecting a system service routine via a provider service table. A service call provider is loaded within an operating system executing in a lower trust security zone. The service call provider comprises metadata indicating a system service routine to be redirected to the service call provider. Based on the metadata, a provider service table is built within a higher trust security zone. The service table redirects the system service routine to the service call provider. Memory page(s) associated with the provider service table are hardware protected, and a read-only view is exposed to the operating system. The provider service table is associated with a user-mode process. A service call for a particular system service routine is received by the operation system from the user-mode process and, based on the provider service table being associated with the user-mode process, the service call is directed to the service call provider.

Abstract: Dynamically overriding a function based on a capability set. A computer system reads a portion of an executable image file. The portion includes a first memory address corresponding to a first callee function implementation. The first memory address was inserted into the portion by a compiler toolchain. Based on extensible metadata included in the executable image file, and based on a capability set that is specific to the computer system, the computer system determines a second memory address corresponding to a second callee function implementation. Before execution of the portion, the computer system modifies the portion to replace the first memory address with the second memory address.

Abstract: Computing systems, devices, and methods of dynamic image composition for container deployment are disclosed herein. One example technique includes receiving a request for accessing a file from a container process. In response to receiving the request, the technique includes querying a mapping table corresponding to the container process to locate an entry corresponding to a file identifier of the requested file. The entry also includes data identifying a file location on the storage device from which the requested file is accessible. The technique further includes retrieving a copy of the requested file according to the file location identified by the data in the located entry in the mapping table and providing the retrieved copy of the requested file to the container process, thereby allowing the container process to access the requested file.
