/* Debug support on a per-module basis
*
* Usage:
*
* Each module can utilize it's own debug mask variable. A set of commonly used
* masks are provided (ERRORS, WARNINGS, TRACE etc..). It is up to each module
* to define module-specific masks using the macros above.
*
* Each module defines a single debug mask variable debug_XXX where the "name" of the module is
* common to all C-files within that module. This requires every C-file that includes a_debug.h
* to define the module name in that file.
*
* Example:
*
* #define ATH_MODULE_NAME htc
* #include "a_debug.h"
*
* This will define a debug mask structure called debug_htc and all debug macros will reference this
* variable.
*
* A module can define module-specific bit masks using the ATH_DEBUG_MAKE_MODULE_MASK() macro:
*
* #define ATH_DEBUG_MY_MASK1 ATH_DEBUG_MAKE_MODULE_MASK(0)
* #define ATH_DEBUG_MY_MASK2 ATH_DEBUG_MAKE_MODULE_MASK(1)
*
* The instantiation of the debug structure should be made by the module. When a module is
* instantiated, the module can set a description string, a default mask and an array of description
* entries containing information on each module-defined debug mask.
* NOTE: The instantiation is statically allocated, only one instance can exist per module.
*
* Example:
*
*
* #define ATH_DEBUG_BMI ATH_DEBUG_MAKE_MODULE_MASK(0)
*
* #ifdef WLAN_DEBUG
* static ATH_DEBUG_MASK_DESCRIPTION bmi_debug_desc[] = {
* { ATH_DEBUG_BMI , "BMI Tracing"}, <== description of the module specific mask
* };
*
* ATH_DEBUG_INSTANTIATE_MODULE_VAR(bmi,
* "bmi" <== module name
* "Boot Manager Interface", <== description of module
* ATH_DEBUG_MASK_DEFAULTS, <== defaults
* ATH_DEBUG_DESCRIPTION_COUNT(bmi_debug_desc),
* bmi_debug_desc);
*
* #endif
*
* A module can optionally register it's debug module information in order for other tools to change the
* bit mask at runtime. A module can call A_REGISTER_MODULE_DEBUG_INFO() in it's module
* init code. This macro can be called multiple times without consequence. The debug info maintains
* state to indicate whether the information was previously registered.
