The related qemu source files are:
- hw/acpi/core.c (handling the -acpitable switch)
- hw/i386/acpi-build.c (the main generator)
- hw/acpi/bios-linker-loader.c (wire format between qemu and firmware)

The related OVMF code lives in:
- OvmfPkg/AcpiPlatformDxe/QemuLoader.h
- OvmfPkg/AcpiPlatformDxe/QemuFwCfgAcpi.c

You might find the following commit message helpful for understanding
the OVMF code:
