I was looking at the monitor code handling the "current CPU", and
noticed that qmp_inject_nmi() looks suspicious: it is a QMP
command, but uses monitor_get_cpu_index().
In addition to the "inject-nmi" QMP command, qmp_inject_nmi() is
* ipmi_do_hw_op() (IPMI_SEND_NMI operation)
This confused me, so I would like to know:
1) What exactly "default CPU" is supposed to mean in the
"inject-nmi" QMP command documentation?
2) To which CPU(s) are NMIs supposed to be sent when triggered by
IPMI messages? I don't know how to test the IPMI code, but it
looks like it will crash if QEMU runs without any monitor.
It doesn't matter which CPU it goes to.
I haven't tested without a monitor, so I'm not sure. Does
another interface into the NMI code need to be added?
