39.Sh INTERFACE LEVEL
40.Sy Evolving -
41This interface is evolving still in illumos.
42API and ABI stability is not guaranteed.
43.Sh PARAMETERS
44.Bl -tag -width Fa
45.It Fa uip
46A pointer to a UFM image that was passed to the driver in its
47.Xr ddi_ufm_op_fill_image 9E
48entry point.
49.It Fa description
50A human-readable description of the firmware image.
51.It Fa nvl
52An nvlist_t with ancillary, device-specific data.
53.It Fa nslots
54The number of firmware slots supported by this firmare image.
55.El
56.Sh DESCRIPTION
57The
58.Fn ddi_ufm_image_set_desc ,
59.Fn ddi_ufm_image_set_misc
60and
61.Fn ddi_ufm_image_set_nslots
62functions are used by device drivers to set information about a firmware
63image on the image structure
64.Fa uip
65as a part of implementing their
66.Xr ddi_ufm_op_fill_image 9E
67entry point.
68For more information on images and the use of these functions, see the
69description of the
70.Fn ddi_ufm_op_fill_image
71function in
72.Xr ddi_ufm 9E .
73.Pp
74The
75.Fn ddi_ufm_image_set_desc
76function sets the description of the firmware image.
77This description is intended for administrators and should convey the intended
78use of the image.
79.Pp
80The
81.Fn ddi_ufm_image_set_misc
82function is used by drivers to set ancillary key-value data that may be
83useful to a consumer.
84The driver should create an nvlist for this purpose with
85.Xr nvlist_alloc 9F
86Once the driver passes the nvlist to the
87.Fn ddi_ufm_image_set_misc
88function, then the driver must not manipulate or free the nvlist at all.
89It is the property of the UFM subsystem.
90.Pp
91The
92.Fn ddi_ufm_image_set_nslots
93function should be called to indicate the number of firmware slots supported
94by this firmware image.
95.Sh CONTEXT
96These functions should only be called in the context of the
97.Xr ddi_ufm_op_fill_image 9E
98entry point.
