## Kernel vs User {#idxd_configs}

The low level library can be initialized either directly via `spdk_idxd_set_config`,
passing in a value of `true` indicates that the IDXD kernel driver is loaded and
that SPDK will use work queue(s) surfaced by the driver.  Passing in `false` means
that the SPDK user space driver will be used to initialize the hardware.
