62 /* Debug support on a per-module basis
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.
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.
76 * #define ATH_MODULE_NAME htc
77 * #include "a_debug.h"
79 * This will define a debug mask structure called debug_htc and all debug macros will reference this
82 * A module can define module-specific bit masks using the ATH_DEBUG_MAKE_MODULE_MASK() macro:
84 * #define ATH_DEBUG_MY_MASK1 ATH_DEBUG_MAKE_MODULE_MASK(0)
85 * #define ATH_DEBUG_MY_MASK2 ATH_DEBUG_MAKE_MODULE_MASK(1)
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.

104 * "Boot Manager Interface", <== description of module
105 * ATH_DEBUG_MASK_DEFAULTS, <== defaults
106 * ATH_DEBUG_DESCRIPTION_COUNT(bmi_debug_desc),
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.
