Migrating pages of different sizes between heterogeneous processors

摘要

One embodiment of the present invention sets forth a computer-implemented method for migrating a memory page from a first memory to a second memory. The method includes determining a first page size supported by the first memory. The method also includes determining a second page size supported by the second memory. The method further includes determining a use history of the memory page based on an entry in a page state directory associated with the memory page. The method also includes migrating the memory page between the first memory and the second memory based on the first page size, the second page size, and the use history.

1. A computer-implemented method for migrating a memory page from a first memory to a second memory, the method comprising:
determining a first page size supported by the first memory; determining a second page size supported by the second memory; determining a use history of the memory page based on an entry in a page state directory (PSD) associated with the memory page, wherein the use history includes a record of recent accesses of the memory page; and migrating the memory page between the first memory and the second memory based on the first page size, the second page size, and the use history.
