Abstract
A system and method for dynamically migrating stash transactions include first and second processing cores, an input/output memory management unit (IOMMU), an IOMMU mapping table, an input/output (I/O) device, a stash transaction migration management unit (STMMU), and an operating system (OS) scheduler. The first core executes a first thread associated with a frame manager. The OS scheduler migrates the first thread from the first core to the second core and generates pre-empt notifiers to indicate scheduling-out and scheduling-in of the first thread from the first core and to the second core. The STMMU uses the pre-empt notifiers to enable dynamic stash transaction migration.
