摘要： Designating and handling confidential memory allocations of virtual memory. An operating system provides a memory allocation flag that applications may use to indicate any arbitrary area of physical memory marked with this flag may contain confidential data and should be handled accordingly. The operating system also ensures that memory allocated with this flag can be placed in physical memory. When freeing up memory, the operating system protects any data in the memory allocated with this flag. For example, the operating system may prevent the confidential memory from being swapped out to storage or from being accessible to other applications, such as debuggers. Alternatively, the operating system may encrypt any data in the confidential memory before it is swapped out to storage.

摘要： A processing device executing an operating system such as a guest operating system generates a bitmap wherein bits of the bitmap represent statuses of memory pages that are available to the operating system. The processing device frees a memory page. The processing device then sets a bit in the bitmap to indicate that the memory page is unused after the memory page is freed.

摘要： A host selects a memory page that has been allocated to a guest for eviction. The host may be a host machine that hosts a plurality of virtual machines. The host accesses a bitmap maintained by the guest to determine a state of a bit in the bitmap associated with the memory page. The host determines whether content of the memory page is to be preserved based on the state of the bit. In response to determining that the content of the memory page is not to be preserved, the host discards the content of the memory page.
摘要翻译：主机选择已分配给guest虚拟机的内存页面进行驱逐。主机可以是托管多个虚拟机的主机。主机访问由访客维护的位图，以确定与存储器页面相关联的位图中的位的状态。主机根据该位的状态确定是否要保留内存页的内容。响应于确定存储器页面的内容不被保留，主机丢弃存储器页面的内容。

摘要： Embodiments of the present invention provide methods and systems for efficiently tracking evicted or non-resident pages. For each non-resident page, a first hash value is generated from the page's metadata, such as the page's mapping and offset parameters. This first hash value is then used as an index to point one of a plurality of circular buffers. Each circular buffer comprises an entry for a clock pointer and entries that uniquely represent non-resident pages. The clock pointer points to the next page that is suitable for replacement and moves through the circular buffer as pages are evicted. In some embodiments, the entries that uniquely represent non-resident pages are a hash value that is generated from the page's inode data.
摘要翻译：本发明的实施例提供了用于有效地跟踪被驱逐或非驻留页面的方法和系统。对于每个非驻留页面，从页面的元数据生成第一个哈希值，例如页面的映射和偏移参数。然后将该第一哈希值用作指向多个循环缓冲器中的一个的索引。每个循环缓冲器包括用于时钟指针的条目和独特地表示非驻留页面的条目。时钟指针指向适合替换的下一页，并在页面被逐出时通过循环缓冲区移动。在一些实施例中，唯一地表示非驻留页面的条目是从页面的inode数据生成的哈希值。

摘要： Embodiments of the present invention provide methods and systems for tuning the size of the cache. In particular, when a page fault occurs, non-resident page data is checked to determine if that page was previously accessed. If the page is found in the non-resident page data, an inter-reference distance for the faulted page is determined and the distance of the oldest resident page is determined. The size of the cache may then be tuned based on comparing the inter-reference distance of the newly faulted page relative to the distance of the oldest resident page.
摘要翻译：本发明的实施例提供了用于调整高速缓存大小的方法和系统。特别地，当发生页面错误时，检查非驻留页面数据以确定是否先前访问了该页面。如果在非驻留页面数据中找到页面，则确定故障页面的参考间距，并且确定最旧驻留页面的距离。然后可以基于比较新故障页面的相对参考距离与最旧的驻留页面的距离来调整高速缓存的大小。

摘要： Embodiments of the present invention provide a mechanism for an operating system and applications to cooperate in memory management. Applications register with the operating system for cooperative memory management. The operating system monitors the memory and determines a memory “pressure” related to the amount of demand for the memory. As the memory pressure increases, the operating system provides a memory pressure signal as feedback to the registered applications. The operating system may send this signal to indicate it is about to commence evicting pages from the memory or when it has commenced swapping out application data. In response to the signal, the registered applications may evaluate the memory pressure, determine which data should be freed, if any, and provide this information back to the operating system. The operating system may then free those portions of memory relinquished by the applications. By releasing data the system may thus avoid swapping and increase its performance.

摘要： A method and apparatus for a cooperative process for negotiating the display of advertisements on a web page or web site. The user configures his preferences for advertisements that are displayed through a browser or plug-in interface when accessing a web page or web site. Each hypertext transfer protocol (HTTP) request generated by the browser includes an indicator of the configured preferences. The web server and/or an advertisement server detect the indicator of advertisement preference and respond to the HTTP request by providing a compliant advertisement for a web page. The advertisement is then displayed by the browser.

摘要： A method and system for scheduling the use of CPU time among processes using a scheduling tree having a yielding indicator. A scheduling tree represents a hierarchy of groups and processes that share central processing unit (CPU) time. A computer system assigns a yield indicator to a first node of the scheduling tree, which represents a first process that temporarily yields the CPU time. The computer system also assigns the yield indicator to each ancestor node of the first node in the scheduling tree. Each ancestor node represents a group to which the first process belongs. The computer system then selects a second process to run on the computer system based on the yield indicator in the scheduling tree.
