/* 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.
