    摘要: A method includes copying a first virtual storage by making, a point-in-time copy of a first page content stored in a first structure by creating a second page content in a second structure, the second page content pointing to actual data pointed to by the first page content, storing the second page content in the second data structure, marking the first page content in the first structure with a bit, copying the virtual page in the event the first page content in the first structure is marked with the bit, storing the copied virtual page in a second virtual storage, altering the second page content to point to the stored virtual page, and using the second virtual storage to perform the core dump process, wherein the second virtual storage is referenced via the second page content stored in the real storage.

    摘要: A computer system includes a translation look-aside (TLB) buffer and a processing unit. The TLB is configured to store an entry that comprises virtual address information, real address information associated with the virtual address information, and additional information corresponding to at least one of the virtual address information and the real address information. The processing unit is configured to control the TLB to modify the additional information while maintaining the entry in a valid state accessible by the processing unit for a translation look-aside operation corresponding to the virtual address information and the real address information.
