[Qemu-devel] [PATCH/RFC 0/6] s390 kdump /soft reset and friends

[Christian Borntraeger]

Alex, Andreas,

here is an implementation for a soft-reset variant that is used
by s390 on kdump. The last patch also wires up the nmi command
to inject a restart interrupt. So there are two methods to trigger
kdump:
- a crash, e.g. via echo c > /proc/sysrq_trigger
- inject-nmi /nmi via virsh/monitor

Feedback is welcome


Christian Borntraeger (4):
  s390: provide I/O subsystem reset
  s390: provide a cpu load normal function
  s390/cpu: split CPU reset into architectured functions
  s390: Implement load normal reset

Eugene (jno) Dvurechenski (2):
  s390/kvm: basic implementation of diagnose 308 subcode 6
  s390: wire up nmi command to raise a RESTART interrupt on S390
