I have an ibm-p8-garrison machine. But I can not find a node "ibm,configure-kernel-dump" under /proc/device-tree. Does garrison machine support fadump? And normally, which component in open-power presents the "ibm,configure-kernel-dump" ? I had though it was in skiboot gitree or garrison-xml gitree, but found nothing. Can anyone give a help? Thx

fadump only exists for guests running under PowerVM (LPARs). It sounds like you're running bare metal (because you mention skiboot). If you're talking about guests on top of KVM then it *could* be implemented, but AFAIK Qemu/KVM do not implement it. cheers

Thank you very much. I am more clear about it now. On Fri, Nov 18, 2016 at 5:29 PM, Michael Ellerman [off-list ref] wrote:
