Abstract
A system and method are disclosed which utilize an enhanced direct memory access (DMA) to both perform a desired data transfer and update data queue directories as needed to properly reflect such data transfer. The enhanced DMA is implemented to receive a data transfer request that comprises at least one data transfer descriptor indicating the desired data transfer, and at least one record update descriptor indicating one or more data queue directories to be updated to properly reflect the desired data transfer. In response, the enhanced DMA both performs the desired data transfer and updates one or more data queue directories to properly reflect such data transfer within the data queue directories. Thereafter, the enhanced DMA notifies the requesting driver that the desired data transfer operation is complete.
