Abstract
Systems and methods are disclosed for implementing a Non-Volatile Memory Express (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.
