[Qemu-ppc] [PATCH 14/21] ppc/pnv: populate device tree for IPMI BT devices |
Date: |
Wed, 5 Apr 2017 14:41:39 +0200 |
When an ipmi-bt device [1] is defined on the ISA bus, we need to
populate the device tree with the object properties. Such devices are
created with the command line options :
-device ipmi-bmc-sim,id=bmc0 -device isa-ipmi-bt,bmc=bmc0,irq=10
