17  * This file contains logic to walk and print a large chunk of configuration
18  * space and many of the capabilities. There are multiple sub-commands that
19  * vector into the same logic (e.g. 'save-cfgspace' and 'show-cfgspace'). In
20  * general, there are a few major goals with this bit of code:
21  *
22  *  o Every field should strive to be parsable and therefore selectable for
23  *    output. This drove the idea that every field has both a short name and a
24  *    human name. The short name is a dot-delineated name. When in parsable
25  *    mode, the name will always refer to a single field. However, for
26  *    convenience for humans, when not trying to be parsable, we show the
27  *    parents in the tree. That is if you specify something like
28  *    'pcie.linkcap.maxspeed', in parsable mode you'll only get that; however,
29  *    in non-parsable mode, you'll get an indication of the capability and
30  *    register that field was in.
31  *
32  *  o Related to the above, parsable mode always outputs a raw, uninterpreted
33  *    value. This was done on purpose. Some fields require interpreting multiple
34  *    registers to have meaning and long strings aren't always the most useful.
35  *
36  *  o Every field isn't always pretty printed. This was generally just a
37  *    decision based upon the field itself and how much work it'd be to fit it
38  *    into the framework we have. In general, the ones we're mostly guilty of
39  *    doing this with are related to cases where there's a scaling value in a
40  *    subsequent register. If you find yourself wanting this, feel free to add
41  *    it.
42  *
43  *  o Currently designated vendor-specific capabilities aren't included here (or
44  *    any specific vendor-specific capabilities for that matter). If they are
45  *    added, they should follow the same angle of using a name to represent a
46  *    sub-capability as we did with HyperTransport.
