|

* Two additional formats:
|
|

*
|
|
||||||
* The format %b is supported to decode error registers.
|
|
||||||
* Its usage is:
|
|
||||||
*
|
|
||||||
* printf("reg=%b\n", regval, "<base><arg>*");
|
|
||||||
*
|
|
||||||
* where <base> is the output base expressed as a control character, e.g.
|
|
||||||
* \10 gives octal; \20 gives hex. Each arg is a sequence of characters,
|
|
||||||
* the first of which gives the bit number to be inspected (origin 1), and
|
|
||||||
* the next characters (up to a control character, i.e. a character <= 32),
|
|
||||||
* give the name of the register. Thus:
|
|
||||||
*
|
|
||||||
* kvprintf("reg=%b\n", 3, "\10\2BITTWO\1BITONE\n");
|
|
||||||
*
|
|
||||||
* would produce output:
|
|

*
|
|
||||||
* reg=3<BITTWO,BITONE>

* XXX: %D -- Hexdump, takes pointer and separator string:
|
|

* ("%6D", ptr, ":") -> XX:XX:XX:XX:XX:XX
|
|

* ("%*D", len, ptr, " " -> XX XX XX XX ...
