31  * SMBIOS Information Routines
32  *
33  * The routines in this file are used to convert from the SMBIOS data format to
34  * a more reasonable and stable set of structures offered as part of our ABI.
35  * These functions take the general form:
36  *
37  *	stp = smb_lookup_type(shp, foo);
38  *	smb_foo_t foo;
39  *
40  *	smb_info_bcopy(stp->smbst_hdr, &foo, sizeof (foo));
41  *      bzero(caller's struct);
42  *
43  *	copy/convert foo members into caller's struct
44  *
45  * We copy the internal structure on to an automatic variable so as to avoid
46  * checks everywhere for structures that the BIOS has improperly truncated, and
47  * also to automatically handle the case of a structure that has been extended.
48  * When necessary, this code can use smb_gteq() to determine whether the SMBIOS
49  * data is of a particular revision that is supposed to contain a new field.

55  * A large number of SMBIOS structures contain a set of common strings used to
56  * describe a h/w component's serial number, manufacturer, etc.  These fields
57  * helpfully have different names and offsets and sometimes aren't consistent.
58  * To simplify life for our clients, we factor these common things out into
59  * smbios_info_t, which can be retrieved for any structure.  The following
60  * table describes the mapping from a given structure to the smbios_info_t.
