Hello, On a POWERPC PowerNV system, the host firmware is stored in a PNOR flash chip which contents is mapped on the LPC bus. This model adds a simple dummy device to map the contents of a block device in the host address space and activates HIOMAP support on the QEMU PowerNV machine to let the host negotiate with the BMC the access to the mapping.
The command options to activate these models in QEMU: -device ipmi-bmc-sim,id=bmc0 -device isa-ipmi-bt,bmc=bmc0,irq=10 \ -drive file=./witherspoon.pnor,format=raw,if=mtd Thanks, C. Changes in v2: - export IPMI_BMC_SIMULATOR() - export ipmi_register_netfn as ipmi_sim_register_netfn Cédric Le Goater (2): ipmi: Add support to customize OEM functions ppc/pnv: Add HIOMAP commands include/hw/ipmi/ipmi.h | 42 ++++++++++++++++ include/hw/ppc/pnv.h | 1 + include/hw/ppc/pnv_pnor.h | 5 ++ hw/ipmi/ipmi_bmc_sim.c | 50 +++---------------- hw/ppc/pnv.c | 1 + hw/ppc/pnv_bmc.c | 102 ++++++++++++++++++++++++++++++++++++++ hw/ppc/pnv_lpc.c | 13 +++++ 7 files changed, 170 insertions(+), 44 deletions(-) -- 2.21.0
