摘要
A data processing system includes a global promotion facility and a plurality of processors coupled by an interconnect. In response to execution of an acquisition instruction by a first processor among the plurality of processors, the first processor transmits an address-only operation on the interconnect to acquire a promotion bit field within the global promotion facility exclusive of at least a second processor among the plurality of processors. In response to receipt of a combined response for the address-only operation representing a collective response of others of the plurality of processors to the address-only operation, the first processor determines whether or not acquisition of the promotion bit field was successful by reference to the combined response.
