Moving ownership of a device between compute elements
摘要:
In an embodiment, a command is received that requests movement of ownership of a target device from an origin compute element to a destination compute element. From the origin compute element, a translation of a virtual bridge identifier to a first secondary bus identifier, a first subordinate bus identifier, and a first MMIO bus address range is removed. To the destination compute element, a translation of the target virtual bridge identifier to a second secondary bus identifier, a second subordinate bus identifier, and a second MMIO bus address range is added. From a south chip that comprises the target virtual bridge, a translation of the target virtual bridge identifier to an identifier of the origin compute element is removed. To the south chip, a translation of the target virtual bridge identifier to an identifier of the destination compute element is added.
