* Tracepoint definitions for s390 ap bus related trace events
*
* There are two AP bus related tracepoint events defined here:
* There is a tracepoint s390_ap_nqap event immediately after a request
* has been pushed into the AP firmware queue with the NQAP AP command.
* The other tracepoint s390_ap_dqap event fires immediately after a
* reply has been pulled out of the AP firmware queue via DQAP AP command.
* The idea of these two trace events focuses on performance to measure
* the runtime of a crypto request/reply as close as possible at the
* firmware level. In combination with the two zcrypt tracepoints (see the
* zcrypt.h trace event definition file) this gives measurement data about
* the runtime of a request/reply within the zcrpyt and AP bus layer.
