Abstract:
A method for recovering from uncorrected memory errors may include receiving, at an operating system, a correctable error (CE) associated with a first memory page. The correctable error is marked in a page table entry describing the first memory page. The first memory page is then migrated, by the operating system, to a second memory page based on the received correctable error.
