(xtracer is TLB memory tracer. It tries to locate first break in code section of traced process using split TLB which is available in intel architecture.
This code can be used to locate OEP of traced process easily. Currently only 1st break is reported, but you may modify code to handle more breaks as that's not a problem at all if you go trough ring3 program which actually controls driver. You may expect to get very good and fast results no matter which protection you are tracing. Time needed to locate OEP is equal to the time needed to execute protection layer without debugger, nor any tracer.)
