Re: [FSL P50x0] KVM HV doesn't work anymore

Hi All,

I bisected today [1] and the bisecting itself was OK but the reverting 
of the bad commit doesn't solve the issue. Do you have an idea which 
commit could be resposible for this issue? Maybe the bisecting wasn't 
successful. I will look in the kernel git log. Maybe there is a commit 
that affected KVM HV on FSL P50x0 machines.

Thanks,
Christian

Hi All,

The RC1 of kernel 5.13 doesn't boot in a virtual e5500 QEMU machine 
with KVM HV anymore. 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-5.13 -drive 
format=raw,file=MintPPC32-X5000.img,index=0,if=virtio -netdev 
user,id=mynet0 -device e1000,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 kernel boots without KVM HV.

Have you already tested KVM HV with the kernel 5.13?

Thanks,
Christian
