Abstract: A data processing system includes a system fabric coupling a coherence manager and an input/output (I/O) requestor. The I/O requestor issues a first snoop request of a first I/O store operation and a subsequent second snoop request of a second I/O store operation. Each of the first and second snoop requests specifies an update to a respective storage location identified by a coherent memory address. The I/O requestor receives respective ownership coherence responses for each of the first and second I/O store operations. The respective first and second ownership coherence responses indicate the coherence manager has concurrent coherence ownership of the memory address for both the first and second I/O store operations. In response to receipt of each of the ownership coherence responses, the I/O requestor issues respective first and second execute coherence responses to command the coherence manager to initiate updates to the respective storage locations.

Abstract: Combining PCIe partial store commands along cache line boundaries, including: receiving a plurality of Peripheral Component Interface express (PCIe) packets; splitting the plurality of PCIe packets along cache line boundaries to generate a plurality of partial store commands; and combining one or more sets of partial store commands to generate one or more combined partial store commands aligned to the cache line boundaries.

Abstract: A foot-operated door opener, with a foot-operated actuator element is located in the lower region of a door for opening the door, and the foot-operated actuator element has a one foot tread element which, when actuated by a foot, at least partially pivots downwards and inwards. The foot tread element is also guided in a forcibly guided manner by way of a forcibly guided element and one forcibly-guided moving element. The foot tread element is connected rotatably to an articulated element and rotatably connected to the forcibly-guided moving element in such a manner that, upon actuation by a foot, the foot tread element both executes a movement downwards and is also moved as a whole at least partially outwards.

Abstract: A foot-operated door-opener, includes a foot-operated actuator element provided in a lower region of a door for opening the door. The foot-operated actuator element includes an upper and a lower foot surface element that are connected to each other by a hinge and, when operated by a user's foot, each upper and lower foot surface element pivots at least partially into the interior of the door. The one or more upper and lower foot surface elements are guided in a guide slot, and the guide slot may have a course which is diagonal, vertical, paraboloid-like, or a combination of such.
