Abstract
Embodiments include a technique for management of data transactions, where the technique includes receiving, at a link interface, a packet from an I/O device, wherein the packet includes address information, and performing, by a host bridge, an address translation for the address information included in the packet. The technique also includes responsive to performing the address translation, determining a target page associated with a translated address of the packet is for at least one of a payload target page or a signaling target page, and appending a flag to a command based at least in part on the target page being associated with the translated address of the packet. The technique includes transmitting the command to an ordering controller for ordering the packet.
