/*
|
|
* IO, register, and NIC memory access functions
|
|
*
|
|
* NOTE on naming convention and macro usage for these
|
|
*
|
|
* A single _ prefix before a an access function means that no state
|
|
* check or debug information is printed when that function is called.
|
|
*
|
|
* A double __ prefix before an access function means that state is checked
|
|
* and the current line number and caller function name are printed in addition
|
|
* to any other debug output.
|
|
*
|
|
* The non-prefixed name is the #define that maps the caller into a
|
|
* #define that provides the caller's name and __LINE__ to the double
|
|
* prefix version.
|
|
*
|
|
* If you wish to call the function without any debug or state checking,
|
|
* you should use the single _ prefix version (as is used by dependent IO
|
|
* routines, for example _iwl_read_direct32 calls the non-check version of
|
|
* _iwl_read32.)
|
|
*
|
|
* These declarations are *extremely* useful in quickly isolating code deltas
|
|
* which result in misconfiguration of the hardware I/O. In combination with
|
|
* git-bisect and the IO debug level you can quickly determine the specific
|
|
* commit which breaks the IO sequence to the hardware.
