Below are steps for verification this patch set.
In a terminal, I launch a KVM virtual machine with qemu command; I
downloaded an Ubuntu iso file [1] ahead and used it as the file system
image (or you could use any distro's iso file as file system image):
$ qemu-system-x86_64 -M pc -enable-kvm -cpu host -m 4096 -hda ubuntu-22.04-desktop-amd64.iso
Then in another terminal, I can use below commands to capture KVM trace
data and report the result:
# cd linux/tools/perf
# ./perf kvm stat record
# ./perf kvm stat report => Output in TUI mode
# ./perf kvm stat report --stdio => Output in stdio mode
Note, I have sent out the patch set v2 to fix a potential building
failure in patch 13. Please work on the new patch set [2].
Thanks,
Leo
