摘要： A method of managing computer memory pages. The sharing of a program-accessible page between two processes is managed by a predefined mechanism of a memory manager. The sharing of a page table page between the processes is managed by the same predefined mechanism. The data structures used by the mechanism are equally applicable to sharing program-accessible pages or page table pages.

摘要： A method for use in a computer. A user of the computer stores a table of selections in a permanent memory structure of the computer, each selection indicating a memory object and one of at least two memory management policies for the memory object. The selections may select from one or more choices: e.g., whether pages of the memory object are to be reserved, or faulted on demand; whether pages of the memory object are to be locked into physical memory of the computer, or to be demand paged from a fluid page pool; whether pages allocated for the memory object are to be zeroed; whether the memory object is to be mapped using shared page tables; or specifying whether memory for the memory object is to be allocated contiguous physical pages of memory. A symbolic name is assigned to each of the memory objects. A non-privileged process issues a request designating one of the memory objects by symbolic name, and allocating memory from a reserved pool of memory for use in the object. The physical pages of the memory objects are managed, each according to the corresponding stored selection.

摘要： A method is disclosed for managing pages of a designated memory object according to selected memory management policies. A user of the computer stores a table of selections in a memory of the computer, each selection indicating a memory object and one of at least two memory management policies for the memory object. The selections may select from one or more choices: e.g., whether pages of the memory object are to be reserved, or faulted on demand; whether pages of the memory object are to be locked into the memory of the computer, or to be demand paged from a fluid page pool; whether pages allocated for the memory object are to be zeroed; whether the memory object is to be mapped using shared page tables; or specifying the number of levels of translation pages of a designated memory object to be shared or whether memory for the memory object is to be allocated contiguous pages of memory. A symbolic name is assigned to each of the memory objects. A non-privileged process issues a request designating one of the memory objects by symbolic name, and allocating memory from a reserved pool of memory for use in the object. The pages of the memory objects are managed, each according to the corresponding stored selection. The managed page may be a translation page describing a virtual-to-physical address mapping for memory references to a program accessible page. The policy selection and an allocation size may be stored in the memory and may refer to management of the program-accessible page. The size of an allocation including the translation page may be computed from the stored size for the program-accessible allocation.
摘要翻译：公开了一种根据所选择的存储器管理策略来管理指定存储器对象的页面的方法。计算机的用户将选择表存储在计算机的存储器中，每个选择指示存储器对象以及用于存储器对象的至少两个存储器管理策略中的一个。选择可以从一个或多个选择中进行选择：例如，是否要保留存储器对象的页面，或者根据需要进行故障; 存储器对象的页面是否被锁定到计算机的存储器中，或者是要从流体页面池中寻呼; 分配给存储器对象的页面是否被归零; 是否使用共享页表来映射内存对象; 或指定要共享的指定存储器对象的翻译页面的级别数量，或者是否为存储器对象的存储器被分配连续的存储器页面。符号名称分配给每个内存对象。非特权进程通过符号名称发出指定其中一个内存对象的请求，并从保留的存储池中分配内存以供对象使用。存储器对象的页面被管理，每个页面根据对应的存储选择。管理页面可以是描述用于对程序可访问页面的存储器引用的虚拟到物理地址映射的翻译页面。策略选择和分配大小可以存储在存储器中，并且可以指代可程序访问页面的管理。包括翻译页面的分配的大小可以从用于程序可访问分配的存储大小计算。
