With it:

root@number:/home/acme# perf test hybrid
 71: Intel PT                                                        :
 71.2: Intel PT hybrid CPU compatibility                             : Ok
 75: x86 hybrid                                                      : Ok

Applied.

Now to look at this on this hybrid system (14700K):
