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

Hello,
Since the RC5 of kernel 5.19, -smp 2 and -smp 4 work again. I don't know
which patch has solved the issue.
Cheers,
Christian
