* DOC: uk_api User-Kernel Interface API
|
*
|
* The User-Kernel Interface abstracts the communication mechanism between the user and kernel-side code of device
|
* drivers developed as part of the Midgard DDK. Currently that includes the Base driver.
|
*
|
* It exposes an OS independent API to user-side code (UKU) which routes functions calls to an OS-independent
|
* kernel-side API (UKK) via an OS-specific communication mechanism.
|
*
|
* This API is internal to the Midgard DDK and is not exposed to any applications.
