Just to clarify: generating ACPI tables is not BIOS
functionality. It ended up in seabios for historical
reasons.
A normal scenario for ACPI tables is that they are written
in ASL and compiled with IASL. The tables are then stored
in some ROM device - most of them, except FACP, can actually
be mapped directly from ROM if necessary.
You won't normally find real BIOS probing PCI slots for
hotplug support and writing EJ0 methods dynamically -
instead the assumption is that hardware (in this case QEMU)
supplies its own static description in form of ACPI tables.
My patchset uses FW_CFG as such a ROM device. It would be
easy to switch to something else instead of FW_CFG.
Is this what you are suggesting?
