/* Debug macros to runtime filter the debug messages sent to the console. 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.
