Also having those functions along with devices models goes along with self enumerating ACPI devices (currently it works for x86 PCI/ISA device but there is no reason that it can't work with other types as well when I get there) > index ea331a20d1..eeb1263c8c 100644 > --- a/hw/acpi/aml-build.c > +++ b/hw/acpi/aml-build.c > @@ -2467,3 +2467,44 @@ Aml *aml_i2c_serial_bus_device(uint16_t address, const char *resource_source) > > return var;
