Abstract: In a computer system having virtual machines, one or more unused bits of a guest physical address range are allocated for aliasing so that multiple virtually addressed sub-pages can be mapped to a common memory page. When one bit is allocated for aliasing, dirty bit information can be provided at a granularity that is one-half of a memory page. When M bits are allocated for aliasing, dirty bit information can be provided at a granularity that is 1/(2M)-th of a memory page.

Abstract translation: 虚拟地址范围的一个或多个未使用的位被分配用于混叠，使得多个虚拟寻址的子页面可以被映射到公共存储器页面。 当分配一个位用于混叠时，可以以占用存储器页面的一半的粒度来提供脏位信息。 当M位被分配用于混叠时，可以以存储器页面的1 /（2M）的粒度来提供脏位信息。

Abstract: The present application is directed to a memory-access-multiplexing memory controller that can multiplex memory accesses from multiple hardware threads, cores, and processors according to externally specified policies or parameters, including policies or parameters set by management layers within a virtualized computer system. A memory-access-multiplexing memory controller provides, at the physical-hardware level, a basis for ensuring rational and policy-driven sharing of the memory-access resource among multiple hardware threads, cores, and/or processors.
