/*
 * This file specifies the WMI interface for the Unified Software
 * Architecture.
 *
 * It includes definitions of all the commands and events. Commands are
 * messages from the host to the target. Events and Replies are messages
 * from the target to the host.
 *
 * Ownership of correctness in regards to WMI commands belongs to the host
 * driver and the target is not required to validate parameters for value,
 * proper range, or any other checking.
 *
 * Guidelines for extending this interface are below.
 *
 * 1. Add new WMI commands ONLY within the specified range - 0x9000 - 0x9fff
 *
 * 2. Use ONLY u32 type for defining member variables within WMI
 *    command/event structures. Do not use u8, u16, bool or
 *    enum types within these structures.
 *
 * 3. DO NOT define bit fields within structures. Implement bit fields
 *    using masks if necessary. Do not use the programming language's bit
 *    field definition.
 *
 * 4. Define macros for encode/decode of u8, u16 fields within
 *    the u32 variables. Use these macros for set/get of these fields.
 *    Try to use this to optimize the structure without bloating it with
 *    u32 variables for every lower sized field.
 *
 * 5. Do not use PACK/UNPACK attributes for the structures as each member
 *    variable is already 4-byte aligned by virtue of being a u32
 *    type.
 *
 * 6. Comment each parameter part of the WMI command/event structure by
 *    using the 2 stars at the begining of C comment instead of one star to
 *    enable HTML document generation using Doxygen.
 *
