I am testing this series. 

Thanks for your time and help.

The first question is: do you plan to add ACPI
support in QEMU?

To the completeness, this should be added. Maybe this could be added at
v3. But I have a look at the kernel PMU driver, it doesn't support
probing through ACPI, although there are some patches[1] out-of-tree.

My in-house kernel uses ACPI for device probing. I had
to force "acpi=off" when I test this patch series.

Guest kernel only boots with ACPI when you add "acpi=force". No need to
add "acpi=off".

The Red Hat kernel uses ACPI by default, when tables are present (Thanks
again for your QEMU table generation patches!)

Oh, I see. Thanks for your explanation.
