30 * SMBIOS Information Routines
32 * The routines in this file are used to convert from the SMBIOS data format to
33 * a more reasonable and stable set of structures offered as part of our ABI.
34 * These functions take the general form:
36 * stp = smb_lookup_type(shp, foo);
37 * smb_foo_t foo;
39 * smb_info_bcopy(stp->smbst_hdr, &foo, sizeof (foo));
40 * bzero(caller's struct);
42 * copy/convert foo members into caller's struct
44 * We copy the internal structure on to an automatic variable so as to avoid
45 * checks everywhere for structures that the BIOS has improperly truncated, and
46 * also to automatically handle the case of a structure that has been extended.
47 * When necessary, this code can use smb_gteq() to determine whether the SMBIOS
48 * data is of a particular revision that is supposed to contain a new field.
50 * Note, when trying to bzero the caller's struct you have to be careful about
51 * versions. One can only bzero the initial version that existed in illumos. In
52 * other words, if someone passes an older library handle that doesn't support a
53 * version you cannot assume that their structures have those additional members
54 * in them. Instead, a 'base' version is introduced for such types that have
55 * differences and instead we only bzero out the base version and then handle
56 * the additional members. In general, because all additional members will be
57 * assigned, there's no reason to zero them out unless they are arrays that
58 * won't be entirely filled in.
60 * Due to history, anything added after the update from version 2.4, in other
61 * words additions from or after '5094 Update libsmbios with recent items'
62 * (4e901881) is currently being used for this. While we don't allow software
63 * compiling against this to get an older form, this was the first major update
64 * and a good starting point for us to enforce this behavior which is useful for
65 * moving forward to making this more public.

80 * A large number of SMBIOS structures contain a set of common strings used to
81 * describe a h/w component's serial number, manufacturer, etc. These fields
82 * helpfully have different names and offsets and sometimes aren't consistent.
83 * To simplify life for our clients, we factor these common things out into
84 * smbios_info_t, which can be retrieved for any structure. The following
85 * table describes the mapping from a given structure to the smbios_info_t.
86 * Multiple SMBIOS stuctures' contained objects are also handled here.
