  • Simultaneous kernel mode and user mode access to a device using the NVMe interface
    Patent number: 10379745
    Abstract: A system and method of enabling simultaneous kernel mode access and user mode access to an NVMe device using the NVMe interface are disclosed. The method includes creating a first set of queue(s) by at least reserving a first range of memory addresses in the kernel space; providing a location address and size of the first set of queues to a controller of the NVMe device; receiving a request for user mode access from a user application process running on the host computer system; and performing the following in response to receiving the request for user mode access: creating a second set of queue(s) by at least reserving a second range of memory addresses mapped for use by the user application process, and providing a location address and size of the second set of queues to the user application process and the controller of the NVMe device.
