Abstract
Embodiment of this disclosure provides a hierarchical structure of ordering points. In some embodiments, the hierarchical structure includes a single primary ordering point (POP) and at least one (or more) auxiliary order point (AOP) of a processing device. In one implementation, the processing device includes one or more cores; and a coherency circuit, operatively coupled to the cores. The processing device is to receive a plurality of memory access requests to be ordered by a first ordering point of the processing device. The processing device determines whether to stop the first ordering point based on a system event. Responsive to determining that the first ordering point is stopped, a second ordering point of the processing device is identified. Thereupon, a memory access request of the plurality of memory access requests is provided to the second ordering point.
