45 lock-free ring buffers acting as queues shared between the kernel and a userland

218 To check if your bus supports RTIO natively, you can check the driver API implementation, if the
219 driver implements the ``iodev_submit`` function of the bus API, then RTIO is supported. If the
224 vendors implement the submit function. With this queue, any I2C bus driver that does not implement
