Background

xNVMe abstracts platform-specific NVMe interfaces behind a common API. Each supported operating system provides a platform implementation that registers a set of backend configs — combinations of implementations for admin, sync, async, memory, and device operations. At runtime, xNVMe selects a config with caps matching the target device. If you wish to override the backend configuration, you can do so via URI options.

For the design rationale and architectural details, see xNVMe Backend Architecture Refactor.
