摘要： Among other things, one or more techniques and/or systems are provided for controlling resource access for background tasks. For example, a background task created by an application may utilize a resource (e.g., CPU cycles, bandwidth usage, etc.) by consuming resource allotment units from an application resource pool. Once the application resource pool is exhausted, the background task is generally restricted from utilizing the resource. However, the background task may also utilize global resource allotment units from a global resource pool shared by a plurality of applications to access the resource. Once the global resource pool is exhausted, unless the background task is a guaranteed background task which can consume resources regardless of resource allotment states of resource pools, the background task may be restricted from utilizing the resource until global resource allotment units within the global resource pool and/or resource allotment units within the application resource pool are replenished.

摘要翻译： 除其他之外，提供一个或多个技术和/或系统用于控制后台任务的资源访问。 例如，由应用程序创建的后台任务可以通过从应用资源池消耗资源分配单元来利用资源（例如，CPU周期，带宽使用等）。 一旦应用资源池耗尽，后台任务一般不受资源的利用。 然而，后台任务还可以利用来自多个应用程序共享的全局资源池的全局资源分配单元来访问资源。 一旦全局资源池耗尽，除非后台任务是可以消耗资源的有保证的后台任务，而不管资源池的资源分配状态如何，则可能会限制后台任务的使用，直到全局资源池中的全局资源分配单元 和/或应用程序资源池中的资源分配单元被补充。

摘要： One or more techniques and/or systems are provided for suspending logically related processes associated with an application, determining whether to resume a suspended process based upon one or more wake policies, and/or managing an application state of an application, such as timer and/or system message data. That is, logically related processes associated with an application, such as child processes, may be identified and suspended based upon logical relationships between the processes (e.g., a logical container hierarchy may be traversed to identify logically related processes). A suspended process may be resumed based upon a set of wake policies. For example, a suspended process may be resumed based upon an inter-process communication call policy that may be triggered by an application attempting to communicate with the suspended process. Application data may be managed while an application is suspended so that the application may be resumed in a current and/or relevant state.

摘要： Operating system virtual memory management for hardware transactional memory. A method may be performed in a computing environment where an application running on a first hardware thread has been in a hardware transaction, with transactional memory hardware state in cache entries correlated by memory hardware when data is read from or written to data cache entries. The data cache entries are correlated to physical addresses in a first physical page mapped from a first virtual page in a virtual memory page table. The method includes an operating system deciding to unmap the first virtual page. As a result, the operating system removes the mapping of the first virtual page to the first physical page from the virtual memory page table. As a result, the operating system performs an action to discard transactional memory hardware state for at least the first physical page. Embodiments may further suspend hardware transactions in kernel mode. Embodiments may further perform soft page fault handling without aborting a hardware transaction, resuming the hardware transaction upon return to user mode, and even successfully committing the hardware transaction.

摘要： Access bit contained in a page table entry is utilized for reducing the number of translation buffer flushes that an operating system needs to issue. A translation buffer flush occurs only when a page table entry is to become invalid and the Access bit of the page table entry is set.
