/*
* 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.

* Tracepoint definitions for the s390 zcrypt device driver
*
* Copyright IBM Corp. 2016,2025
* Author(s): Harald Freudenberger <freude@de.ibm.com>
*
* Currently there are two tracepoint events defined here.
* An s390_zcrypt_req request event occurs as soon as the request is
* recognized by the zcrypt ioctl function. This event may act as some kind
* of request-processing-starts-now indication.
* As late as possible within the zcrypt ioctl function there occurs the
* s390_zcrypt_rep event which may act as the point in time where the
* request has been processed by the kernel and the result is about to be
* transferred back to userspace.
* The glue which binds together request and reply event is the ptr
* parameter, which is the local buffer address where the request from
* userspace has been stored by the ioctl function.
*
* The main purpose of this zcrypt tracepoint api is to get some data for
* performance measurements together with information about on which card
* and queue the request has been processed. It is not an ffdc interface as
* there is already code in the zcrypt device driver to serve the s390
* debug feature interface.
