Patent number: 11941298Abstract: A host system initiates an abort of a command that has been placed into a submission queue (SQ) of the host system. The host system identifies at least one of a first outcome and a second outcome. When the first outcome indicates that the command is not completed and the second outcome indicates that the SQ entry has been fetched from the SQ, the host system sends an abort request to a storage device, and issues a cleanup request to direct the host controller to reclaim host hardware resources allocated to the command. The host system adds a completion queue (CQ) entry to a CQ and sets an overall command status (OCS) value of the CQ entry based on at least one of the first outcome and the second outcome.Type: GrantFiled: April 19, 2022Date of Patent: March 26, 2024Assignee: MediaTek Inc.Inventors: Chih-Chieh Chou, Chia-Chun Wang, Liang-Yen Wang, Chin Chin Cheng, Szu-Chi Liu
