Hello,
The first patches improve the LPC support for the POWER8NVL (nvlink)
systems and for multichip systems. Next, we add IPMI support to the
machine which is required to power off and reboot a PowerNV system. To
make use of it, a BT device and an BMC simulator need to be defined on
the command line:
-device ipmi-bmc-sim,id=bmc0 -device isa-ipmi-bt,bmc=bmc0,irq=10
To improve the sensor and FRU support, one can use the following
options for the simulator:
sdrfile=./palmetto-SDR.bin,fruareasize=256,frudatafile=./palmetto-FRU.bin
To test, grab a kernel and a rootfs image here :

Thanks,
C.
Changes since v1:
- moved the IRQ handler in pnv_lpc.c and introduced pnv_lpc_isa_irq_create()
- only add the "primary" property on the LPC bus of chip 0
- reworked the assignement of the ISA IO base in the 'reg' array
property
- changed the type of the 'bmc' attribute of the machine
