Title: The Innovations of Ji Dai
Introduction
Ji Dai is a prominent inventor based in Shanghai, China. He has made significant contributions to the field of technology, particularly in the area of non-volatile memory express (NVMe) systems. With a total of 3 patents to his name, Ji Dai continues to push the boundaries of innovation.
Latest Patents
One of Ji Dai's latest patents is titled "User mode direct data access to non-volatile memory express device via kernel-managed queue pair." This patent discloses systems and methods for implementing an NVMe driver in a computer system. The method involves mapping a memory buffer into a user mode address space to facilitate data transfer with an NVMe device via direct memory access (DMA). Additionally, a first NVMe queue pair, including a submission queue (SQ) and a completion queue (CQ), is mapped into the user mode address space, allowing a user mode component to submit commands to the NVMe device. The method further enables the user mode component to ring a doorbell at the NVMe device. Finally, an NVMe command is processed in kernel mode using a second NVMe queue pair comprising a second SQ and a second CQ.
Another notable patent is "Semi-polling input/output completion mode for non-volatile memory express completion queue." This patent describes a system and method for using a semi-polling model to monitor an NVMe completion queue (CQ). The method, implemented at an interrupt thread, includes receiving an input/output (I/O) request from an application and submitting a submission queue (SQ) entry into an NVMe SQ in response to the I/O request. The method further includes registering for notifications from a polling thread after submitting the SQ entry and receiving, from the polling thread, a notification of the presence of a CQ entry within an NVMe CQ. Additionally, the method involves removing the CQ entry from the NVMe CQ and notifying the application of the completion of the I/O request.
