Hello, Now that we have support for the interrupt controller in the PowerNV machine, we can start adding controllers depending on it. First of these, is the Processor Service Interface (PSI), which handles the external interrupt, and then a minimal model for the OCC. They have been reviewed a couple of time and should be ready to be merged. These first two patches give us a usable PCI-less PowerNV machine, which is an important step to complete the overall model.
Some fixes improving support for the POWER8NVL (nvlink) and multichip follow. 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 Most of the IPMI patches have been discussed already on the list and some should go through Corey Minyard's tree or Michael S. Tsirkin's if considered ready. Last is a PCIe host bridge model (PHB3) as found on the Power8 machines. Power9 will use a PHB4 which is very close. Nevertheless, it is a large model and it depends on a few helpers in the PCI core which need to be discussed. (I would need some help here) 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.
