Status handling for transfer of data blocks between a local side and a host side

摘要

An information handling system transfers data blocks between a host processing side having a host processing unit and a host memory and a local processing side having a local processing unit and a local memory. The host memory includes a status queue memory portion having a plurality of status queue images each image storing a status information relating to a corresponding data transfer. The status information relating to data block transfers are posted on the host processing side. The host processing unit, upon system initialization, sets up a status queue register set within the local processing side defining status queue parameters including the location of the status queue memory portion within the host memory and pointer values pointing to where status queue images are to be stored and from where they are to be retrieved.
