[Qemu-devel] [PATCH v3 0/8] pnv: improvement of LPC support and IPMI support

["Cédric Le Goater" <clg@kaod.org>]

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 v2:

 - used PNV_LPC() macro to cast the 'opaque' parameter
 - introduced a pnv_chip_lpc_offset() routine to locate the LPC node
   of a chip   
 - set the "primary" property on the LPC bus of chip 0 from the machine
 - used the pnv_chip_lpc_offset() routine to scan the default LPC bus
 - removed the initializer of io_base

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
