36 | /* | |
37 | * IO, register, and NIC memory access functions | |
38 | * | |
39 | * NOTE on naming convention and macro usage for these | |
40 | * | |
41 | * A single _ prefix before a an access function means that no state | |
42 | * check or debug information is printed when that function is called. | |
43 | * | |
44 | * A double __ prefix before an access function means that state is checked | |
775ea378 TW |
45 | * and the current line number and caller function name are printed in addition |
46 | * to any other debug output. | |
b481de9c ZY |
47 | * |
48 | * The non-prefixed name is the #define that maps the caller into a | |
775ea378 TW |
49 | * #define that provides the caller's name and __LINE__ to the double |
50 | * prefix version. | |
b481de9c ZY |
51 | * |
52 | * If you wish to call the function without any debug or state checking, | |
53 | * you should use the single _ prefix version (as is used by dependent IO | |
3395f6e9 TW |
54 | * routines, for example _iwl_read_direct32 calls the non-check version of |
55 | * _iwl_read32.) | |
b481de9c ZY |
56 | * |
57 | * These declarations are *extremely* useful in quickly isolating code deltas | |
a96a27f9 | 58 | * which result in misconfiguration of the hardware I/O. In combination with |
b481de9c ZY |
59 | * git-bisect and the IO debug level you can quickly determine the specific |
60 | * commit which breaks the IO sequence to the hardware. | |
