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.
