Moreover, the DEBUG_***_ERROR variables // force the compiler to display on TXT0 the error messages generated by // the low-level kernel function, to help the error cause analysis. // // 2) The other debug variable forece the compiler to display on TXT0 a trace for one // specific kernel function, or one small group of functions. // All these trace variables (but locks, kmem, kcm) respect the following rules: // - the trace is generated if the debug variable is non zeo. // - trace is generated only when cycle > debug_value. // - detailed trace is enabled when (debug_value & 0x1) is non zero. //////////////////////////////////////////////////////////////////////////////////////// // error reporting variables #define DEBUG_DEV_NIC_ERROR 1 #define DEBUG_KCM_ERROR 1 #define
