62 /* Debug support on a per-module basis
63  *
64  * Usage:
65  *
66  *   Each module can utilize it's own debug mask variable.  A set of commonly used
67  *   masks are provided (ERRORS, WARNINGS, TRACE etc..).  It is up to each module
68  *   to define module-specific masks using the macros above.
69  *
70  *   Each module defines a single debug mask variable debug_XXX where the "name" of the module is
71  *   common to all C-files within that module.  This requires every C-file that includes a_debug.h
72  *   to define the module name in that file.
73  *
74  *   Example:
75  *
76  *   #define ATH_MODULE_NAME htc
77  *   #include "a_debug.h"
78  *
79  *   This will define a debug mask structure called debug_htc and all debug macros will reference this
80  *   variable.
81  *
82  *   A module can define module-specific bit masks using the ATH_DEBUG_MAKE_MODULE_MASK() macro:
83  *
84  *      #define ATH_DEBUG_MY_MASK1  ATH_DEBUG_MAKE_MODULE_MASK(0)
85  *      #define ATH_DEBUG_MY_MASK2  ATH_DEBUG_MAKE_MODULE_MASK(1)
86  *
87  *   The instantiation of the debug structure should be made by the module.  When a module is
88  *   instantiated, the module can set a description string, a default mask and an array of description
89  *   entries containing information on each module-defined debug mask.
90  *   NOTE: The instantiation is statically allocated, only one instance can exist per module.
91  *
92  *   Example:
93  *
94  *
95  *   #define ATH_DEBUG_BMI  ATH_DEBUG_MAKE_MODULE_MASK(0)
96  *
97  *   #ifdef DEBUG
98  *   static struct ath_debug_mask_description bmi_debug_desc[] = {
99  *       { ATH_DEBUG_BMI , "BMI Tracing"},   <== description of the module specific mask
100  *   };
101  *
102  *   ATH_DEBUG_INSTANTIATE_MODULE_VAR(bmi,
103  *                                    "bmi"  <== module name
104  *                                    "Boot Manager Interface",  <== description of module
105  *                                    ATH_DEBUG_MASK_DEFAULTS,          <== defaults
106  *                                    ATH_DEBUG_DESCRIPTION_COUNT(bmi_debug_desc),
107  *                                    bmi_debug_desc);
108  *
109  *   #endif
110  *
111  *  A module can optionally register it's debug module information in order for other tools to change the
112  *  bit mask at runtime.  A module can call  A_REGISTER_MODULE_DEBUG_INFO() in it's module
113  *  init code.  This macro can be called multiple times without consequence.  The debug info maintains
114  *  state to indicate whether the information was previously registered.
