+// Description:
+// e32test\debug\t_debugapi.cpp
+// User-side harness for LDD-based debug agent that checks debug API 
+// interface provided by kernel extension kdebug.dll (ARMv5) or kdebugv6 (ARMv6).
+// It uses debug port to print the list of processes, threads, etc.
+// Usage: t_debugapi [process] [thread] [chunk] [ipaccess]
+// Performs all steps if there are no input arguments.
+// The test is automated (does not require any input argument or manual assistance, but needs
+// non-standard image file that includes kdebug.dll (ARMv5 based target) or kdebugV6.dll  
+// (ARMv6 based target). It can be achieved by adding: #define STOP_MODE_DEBUGGING in .oby/iby file.
+// Supported and tested on H2 (ARMv5) and integrator_1136 (ARMv6) platforms.
+// It requires D_DEBUGAPI.DLL as well.
+// Using debug interfaca only, it completes (prints) the list of:
+// - processes;
+// - threads;
+// - chunks;
+// in the system. On multiple-memory-model based target (ARMv6 architecture), 
+// it also reads from address space of another process. This part is not checked 
+// on moving-memory-model target (ARMv5) (e.g. always passes).
+// Note: The test may cause system fail on ARM1136(r0p2) with L210 cache due to Erratum 317041.
+// In that case, uncomment two relevant lines in DDebugAPIChecker::ReadFromOtherProcessArmv6 (in
+// d_debugapi.cia) and rebuild d_debugapi.ldd.
+//
