1002  * Pure dynamic property declaration. A pure dynamic property is a property
1003  * for which a driver's prop_op(9E) implementation will return a value on
1004  * demand, but the property name does not exist on a property list (global,
1005  * driver, system, or hardware) - the person asking for the value must know
1006  * the name and type information.
1007  *
1008  * For a pure dynamic property to show up in a di_init() devinfo shapshot, the
1009  * devinfo driver must know name and type. The i_ddi_prop_dyn_t mechanism
1010  * allows a driver to define an array of the name/type information of its
1011  * dynamic properties. When a driver declares its dynamic properties in a
1012  * i_ddi_prop_dyn_t array, and registers that array using
1013  * i_ddi_prop_dyn_driver_set() the devinfo driver has sufficient information
1014  * to represent the properties in a snapshot - calling the driver's
1015  * prop_op(9E) to obtain values.
1016  *
1017  * The last element of a i_ddi_prop_dyn_t is detected via a NULL dp_name value.
1018  *
1019  * A pure dynamic property name associated with a minor_node/dev_t should be
1020  * defined with a dp_spec_type of S_IFCHR or S_IFBLK, as appropriate.  The
1021  * driver's prop_op(9E) entry point will be called for all
1022  * ddi_create_minor_node(9F) nodes of the specified spec_type. For a driver
1023  * where not all minor_node/dev_t combinations support the same named
1024  * properties, it is the responsibility of the prop_op(9E) implementation to
1025  * sort out what combinations are appropriate.
1026  *
1027  * A pure dynamic property of a devinfo node should be defined with a
1028  * dp_spec_type of 0.
1029  *
1030  * NB: Public DDI property interfaces no longer support pure dynamic
1031  * properties, but they are still still used.  A prime example is the cmlb
1032  * implementation of size(9P) properties. Using pure dynamic properties
1033  * reduces the space required to maintain per-partition information. Since
1034  * there are no public interfaces to create pure dynamic properties,
1035  * the i_ddi_prop_dyn_t mechanism should remain private.
