The ISSEI (Intel Silicon Security Engine Interface) subsystem provides a communication channel between the host and the Silicon Security Engine. Prepare basic driver functions and character device for user-space communication. Add DMA access routines for ISSEI HECI devices. Add of DMA-related structures and implementation of routines for setting up DMA, as well as reading and writing DMA buffers.

Driver implementer's API guide

==============================
|
|
|
|
The kernel offers a wide variety of interfaces to support the development
|
|
of device drivers. This document is an only somewhat organized collection
|
|
of some of those interfaces — it will hopefully get better over time! The
|
|
available subsections can be seen below.

General information for driver authors
|
|
======================================
|
|
|
|
This section contains documentation that should, at some point or other, be
|
|
of interest to most developers working on device drivers.
