+ * IBM ASM Service Processor Device Driver
+ *
+ * Copyright (C) IBM Corporation, 2004
+ *
+ * Author: Max Asböck <amax@us.ibm.com>
+ *
+ * This driver is based on code originally written by Pete Reynolds
+ * and others.
+ */
+
+/*
+ * The ASM device driver does the following things:
+ *
+ * 1) When loaded it sends a message to the service processor,
+ * indicating that an OS is * running. This causes the service processor
+ * to send periodic heartbeats to the OS.
+ *
+ * 2) Answers the periodic heartbeats sent by the service processor.
+ * Failure to do so would result in system reboot.
+ *
+ * 3) Acts as a pass through for dot commands sent from user applications.
+ * The interface for this is the ibmasmfs file system.
+ *
+ * 4) Allows user applications to register for event notification. Events
+ * are sent to the driver through interrupts. They can be read from user
+ * space through the ibmasmfs file system.
+ *
+ * 5) Allows user space applications to send heartbeats to the service
+ * processor (aka reverse heartbeats). Again this happens through ibmasmfs.
+ *
+ * 6) Handles remote mouse and keyboard event interrupts and makes them
+ * available to user applications through ibmasmfs.
+ *
