Abstract: A handshake communication mechanism between a host and an end-point device permits multiple Base Address Registers (BAR registers) to be configured to size or resize the mapped address spaces associated with each BAR register. In one embodiment, the handshake communication mechanism includes a single address space reconfiguration request which may be transmitted in a single transaction layer packet, to request the configuration of multiple BAR registers of an end-point device. Other features and advantages may be realized, depending upon the particular application.
