The main question, IMHO, is how to proceed for supporting both PIIX4 and q35. The two extreme possibilities are: - use a single binary for everything - use two binaries for everything Right now, you do a mix of the two, where you have two DSDTs and one binary. Furthermore, PIIX4 is still a "preferred" chipset in that its DSDT is embedded in SeaBIOS and q35's isn't. With more than one chipset being supported, and with the desire to support OVMF/UEFI as an alternative firmware, I think it makes sense to move QEMU towards a model more similar to CoreBoot's, where QEMU itself makes the default ACPI tables and passes them to SeaBIOS or OVMF via fw_cfg. So my favorite choice is to move the DSDT to fw_cfg, and keep a single binary for everything else. I don't really care whether the DSDT sources live in the SeaBIOS or QEMU repository, though the former makes more sense until all things ACPI are done in QEMU.
