Hello Juergen, Hello All, Since the RC1 of kernel 5.13, -smp 2 and -smp 4 don't work with a virtual e5500 QEMU KVM-HV machine anymore. [1] I see in the serial console, that the uImage doesn't load. I use the following QEMU command for booting: qemu-system-ppc64 -M ppce500 -cpu e5500 -enable-kvm -m 1024 -kernel uImage -drive format=raw,file=MintPPC32-X5000.img,index=0,if=virtio -netdev user,id=mynet0 -device virtio-net,netdev=mynet0 -append "rw root=/dev/vda" -device virtio-vga -device virtio-mouse-pci -device virtio-keyboard-pci -device pci-ohci,id=newusb -device usb-audio,bus=newusb.0 -smp 4 The kernels boot without KVM-HV. Summary for KVM-HV: -smp 1 -> works -smp 2 -> doesn't work -smp 3 -> works -smp 4 -> doesn't work I used -smp 4 before the RC1 of kernel 5.13 because my FSL P5040 BookE machine [2] has 4 cores. Does this patch solve this issue? [3] Thanks, Christian [1] https://lists.ozlabs.org/pipermail/linuxppc-dev/2021-May/229103.html [2] http://wiki.amiga.org/index.php?title=X5000 [3] https://lists.ozlabs.org/pipermail/linuxppc-dev/2021-September/234152.html
