Abstract: A host system coupled to a storage system provides hardware support for command abort. The host system includes a host controller, which detects that a host driver has disabled an enable indicator of a submission queue (SQ). In response to the detection, the host controller stops further fetching from the SQ. The host controller sends all entries that have been fetched from the SQ to the storage device, and sets a status indicator of the SQ to indicate stopped fetching of the SQ.

Abstract: 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.

Abstract: A controller integrated circuit (IC) and a method for controlling a storage device for a host device to enhance overall performance are provided. The host device may include the controller IC, where the storage device is positioned outside the host device. The controller IC may include a plurality of first queues, a first queue notification register and a first queue auxiliary notification register, where each first queue of the first queues is arranged to queue first queue entries for being used to interact with the storage device. The first queue notification register may store first queue notification information for indicating whether any first queue of the plurality of first queues sends any first interrupt. The first queue auxiliary notification register may store first queue auxiliary notification information for indicating which first queue of the plurality of first queues is the any first queue that has sent the any first interrupt.

Abstract: A system includes a host, a storage host controller, and a storage device. The host includes a hypervisor for running a first virtual machine and a second virtual machine. The storage host controller includes a plurality of first multi-circular queues (MCQs) assigned to the first virtual machine and a plurality of second MCQs assigned to the second virtual machine. The plurality of first MCQs assigned to the first virtual machine is used to control operations of the first virtual machine. The plurality of second MCQs assigned to the second virtual machine is used to control operations of the second virtual machine. The storage device has a first portion linked to the first virtual machine for being accessed by the first virtual machine, and a second portion linked to the second virtual machine for being accessed by the second virtual machine wherein the first portion and the second portion are isolated.

Abstract: A host system operates to manage a storage device. The host system initiates an abort of a command when the command has been fetched from a submission queue (SQ) of the host system and the SQ entry has been fetched from the SQ and the host system has not received a corresponding command completion response from the storage device. The host system sends an abort request to the storage device, and issues a cleanup request to direct a 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 to indicate completion of the abort request.

Abstract: A method for searching a buffer of a non-volatile storage host controller is provided. The method includes obtaining a command-based identifier of a command when a system level setting of a first format is enabled; and checking a format information on whether the first format or a second format is used to execute the command according to the identifier. A system for searching a buffer of a non-volatile storage host controller is provided. A host of the system searches a buffer by using the command-based identifier when a system level setting of a first format is enabled and check format information on whether the first format or a second format is used to execute the command according to the identifier.
