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 : https://openpower.xyz/job/openpower-op-build/distro=ubuntu,target=palmetto/lastSuccessfulBuild/artifact/images/zImage.epapr https://openpower.xyz/job/openpower-op-build/distro=ubuntu,target=palmetto/lastSuccessfulBuild/artifact/images/rootfs.cpio.xz The full patchset is available here : https://github.com/legoater/qemu/commits/powernv-ipmi-2.9 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 Benjamin Herrenschmidt (1): ppc/pnv: Add support for POWER8+ LPC Controller Cédric Le Goater (7): ppc/pnv: enable only one LPC bus ppc/pnv: scan ISA bus to populate device tree ppc/pnv: populate device tree for RTC devices ppc/pnv: populate device tree for serial devices ppc/pnv: populate device tree for IPMI BT devices ppc/pnv: add initial IPMI sensors for the BMC simulator ppc/pnv: generate an OEM SEL event on shutdown hw/ppc/Makefile.objs | 2 +- hw/ppc/pnv.c | 212 ++++++++++++++++++++++++++++++++++++++--------- hw/ppc/pnv_bmc.c | 122 +++++++++++++++++++++++++++ hw/ppc/pnv_lpc.c | 120 ++++++++++++++++++++++++--- include/hw/ppc/pnv.h | 11 +++ include/hw/ppc/pnv_lpc.h | 10 +++ 6 files changed, 425 insertions(+), 52 deletions(-) create mode 100644 hw/ppc/pnv_bmc.c -- 2.7.4
