In * general, there are four forms of the debug macros: * * [a-z]dbg() -- Outputs messages to the console similar to printf() except * that the output is not buffered. The first character indicates the * system system (e.g., n=network, f=filesystm, etc.). If the first * character is missing (i.e., dbg()), then it is common. The common * dbg() macro is enabled by CONFIG_DEBUG. Subystem debug requires an * additional configuration setting to enable it (e.g., CONFIG_DEBUG_NET * for the network, CONFIG_DEBUG_FS for the file syste, etc). * * In general, error messages and output of importance use [a-z]dbg(). * [a-z]dbg() is implementation dependent but usually uses file descriptors. * (that is a problem only because the interrupt task may have re- * directed stdout). Therefore [a-z]dbg() should not be used in interrupt * handlers. * * [a-z]vdbg() -- Identifcal to [a-z]dbg() except that it also requires that * CONFIG_DEBUG_VERBOSE be defined. This is intended for general debug * output that you would normally want to suppress. * * [a-z]lldbg() -- Identical to [a-z]dbg() except this is uses special * interfaces provided by architecture-specific logic to talk directly * to the underlying console hardware. If the architecture provides such * logic, it should define CONFIG_ARCH_LOWPUTC. * * [a-z]lldbg() should not be used in normal code because the implementation * probably disables interrupts and does things that are not consistent with * good real-time performance. However, [a-z]lldbg() is particularly useful * in low-level code where it is inappropriate to use file descriptors. For * example, only [a-z]lldbg() should be used in interrupt handlers. * * [a-z]llvdbg() -- Identifcal to [a-z]lldbg() except that it also requires that * CONFIG_DEBUG_VERBOSE be defined. This is intended for general debug * output that you would normally want to suppress. */ #ifdef CONFIG_HAVE_FUNCTIONNAME # define EXTRA_FMT "%s: " # define EXTRA_ARG ,__FUNCTION__ #else # define EXTRA_FMT #
