s390x/cpu: expose the guest crash information
This patch is the s390 implementation of guest crash information,
similar to commit d187e08dc4 ("i386/cpu: add crash-information QOM
property") and the related commits. We will detect several crash
reasons, with the "disabled wait" being the most important one, since
this is used by all s390 guests as a "panic like" notification.
Demonstrate these ways with examples as follows.
1. crash-information QOM property;
Run qemu with -qmp unix:qmp-sock,server, then use utility "qmp-shell"
to execute "qom-get" command, and might get the result like,
(QEMU) (QEMU) qom-get path=/machine/unattached/device[0] \
property=crash-information
{"return": {"core": 0, "reason": "disabled-wait", "psw-mask": 562956395872256, \
"type": "s390", "psw-addr": 1102832}}
2. GUEST_PANICKED event reporting;
Run qemu with a socket option, and telnet or nc to that,
-chardev socket,id=qmp,port=4444,host=localhost,server \
-mon chardev=qmp,mode=control,pretty=on \
Negotiating the mode by { "execute": "qmp_capabilities" }, and the crash
information will be reported on a guest crash event like,
{
"timestamp": {
"seconds": 1518004739,
"microseconds": 552563
},
"event": "GUEST_PANICKED",
"data": {
"action": "pause",

"reason": "disabled-wait",
"psw-mask": 562956395872256,
"type": "s390"
}
}
}
3. log;
Run qemu with the parameters: -D <logfile> -d guest_errors, to
specify the logfile and log item. The results might be,
Guest crashed on cpu 0: disabled-wait

similar to commit d187e08dc4 ("i386/cpu: add crash-information QOM
property") and the related commits. We will detect several crash
reasons, with the "disabled wait" being the most important one, since
this is used by all s390 guests as a "panic like" notification.
Demonstrate these ways with examples as follows.
1. crash-information QOM property;
Run qemu with -qmp unix:qmp-sock,server, then use utility "qmp-shell"
to execute "qom-get" command, and might get the result like,
(QEMU) (QEMU) qom-get path=/machine/unattached/device[0] \
property=crash-information
{"return": {"core": 0, "reason": "disabled-wait", "psw-mask": 562956395872256, \
"type": "s390", "psw-addr": 1102832}}
2. GUEST_PANICKED event reporting;
Run qemu with a socket option, and telnet or nc to that,
-chardev socket,id=qmp,port=4444,host=localhost,server \
-mon chardev=qmp,mode=control,pretty=on \
Negotiating the mode by { "execute": "qmp_capabilities" }, and the crash
information will be reported on a guest crash event like,
{
"timestamp": {
"seconds": 1518004739,
"microseconds": 552563
},
"event": "GUEST_PANICKED",
"data": {
"action": "pause",
"info": {
"core": 0,
"psw-addr": 1102832,
"reason": "disabled-wait",
"psw-mask": 562956395872256,
"type": "s390"
}
}
}
3. log;
Run qemu with the parameters: -D <logfile> -d guest_errors, to
specify the logfile and log item. The results might be,
Guest crashed on cpu 0: disabled-wait
PSW: 0x0002000180000000 0x000000000010d3f0
