 .. note::
 
   * PC sampling feature is currently in BETA version. To enable PC sampling, you have to explicitly enable it with block index 21.
+  * PC sampling now only shows assembly instructions collected in our record of pc samples and not all instructions of compiled code are represented.
   * To associate PC sampling info back to HIP source code, you need to build the profiling target app with ``-g`` to keep the symbols. Otherwise, PC sampling info will be only associated with assembly lines.
