There were discussions on potentially introducing a middle component to generate the tables. Coreboot was raised as a possibility, and David thought it would be okay to use coreboot for both OVMF and SeaBIOS. The possibility was also raised of a "rom" that lives in the qemu repo, is run in the guest, and generates the tables (which is similar to the hvmloader approach that Xen uses).
Given the objections to implementing ACPI directly in QEMU,
I don't think that's a given, just yet.
So far Anthony asked to be shown the kind of project that ACPI generation in QEMU would enable. Since qemu community wasn't directly exposed to the ACPI-related patches it's easy to see how qemu maintainers won't be aware of the churn and maintainance overhead caused by generating them on the guest side.
That seems reasonable, so please hang on just a little bit longer until I post acpi hotplug support for pci bridges based on this code.
Then we can discuss.
