Hi, I am doing the virtio performance analysis on PowerPC,with the updated QEMU I had observed that the EMUL_MTSPR instruction counts in KVM Exit
Sounds you are saying this behaviour is only reproduced after you update QEMU. If so, you can use 'git bisect' easily to figure out this issued commit.
count is going really high when I send packets from Guest with respect to without sending network packets from Guest. I had added few prints and found that special register number 336 which corresponds to TSR:Timer Status is been called number of times
Which platform? Which CPU core?
which I think could result in a higher CPU Utilization.
How many processes else are running except for KVM guest? Tiejun
I would be thankful if I could get some opinions about this observation. Regards Nitesh Narayan Lal -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
