Abstract
Gap processing is utilized to reorder out-of-order submissions on the normal submission queue. The controller is able to process logical block addresses (LBAs) that are received through the use of a normal NVMe submission queue (SQ) and a private SQ. The normal NVMe SQ will store the LBAs of commands that may arrive out of sequential order for processing. The private SQ is used to store an LBA that is received after a gap is detected. The private SQ is only read after a command is received on the normal SQ that contains the current First Gap LBA. If no entry in the private SQ is sequentially after the first gap LBA, no processing of the private SQ occurs. If the pulled LBA is next, then the LBA will be processed by the data storage device. If the pulled LBA is not next, then the zone gap processing will send the LBA back to the private SQ.
