Re: Tracepoints and Timestamps


If you use the gdbserver that include in GDB source, you can access
special tvariable $trace_timestamp.

If not, I think maybe you can add a special tvariable that access to
timebase registers?(tbl and tbu)  to gdbserver.  Then you can collect
it when you want it.

Thanks,
Hui
