Shared memory mechanism to support fast transport of SQ/CQ pair communication between SSD device driver in virtualization environment and physical SSD

Abstract:

An apparatus is described. The apparatus includes an accelerator to be coupled to a memory region that the accelerator shares with a virtualization environment comprising a guest OS, a guest VM and an SSD device driver. The accelerator is to forward a submission queue doorbell setting made by the SSD device driver in the shared memory to a corresponding submission queue doorbell in an SSD controller.
