30 | // 1) All errors detected by the kernel caused by a system call are reported to the |
---|
31 | // user process using the ERRNO mechanism. Moreover, the DEBUG_***_ERROR variables |
---|
32 | // force the compiler to display on TXT0 the error messages generated by |
---|
33 | // the low-level kernel function, to help the error cause analysis. |
---|
34 | // |
---|
35 | // 2) The other debug variable forece the compiler to display on TXT0 a trace for one |
---|
36 | // specific kernel function, or one small group of functions. |
---|
37 | // All these trace variables (but locks, kmem, kcm) respect the following rules: |
---|
38 | // - the trace is generated if the debug variable is non zeo. |
---|
39 | // - trace is generated only when cycle > debug_value. |
---|
40 | // - detailed trace is enabled when (debug_value & 0x1) is non zero. |
