Could we just have qemu build the hpet tables and pass them through to seabios? Perhaps using the qemu_cfg_acpi_additional_tables() method.Possible, and I considered that. I personally prefer to pass minimum information required for seabios to discover underlying HW and leave ACPI table creation to seabios. That is how things done for HW that seabios can actually detect. If we will go your way pretty soon we will move creation of ACPI/SMBIOS/MP tables into qemu and IMHO this will be step backworkds.
I agree. ACPI is a firmware/OS interface. If we move ACPI table generation into qemu, it becomes a mixed hardware/firmware/OS interface.
Better keep those interfaces separate: hardware/firmware (fwcfg) and firmware/OS (acpi).
