I don't know anything either, but I assume not? With a device driver you'd be handling interrupts directly by registering an interrupt service routine and all that good stuff. io_uring is a user->kernel API because userspace doesn't handle those interrupts directly. Instead, device driver ISRs fill buffers and what have you, then kernel notifies user via io_uring that data is ready.
