Testing vms->ras first is cheaper than calling object_resolve_path_type(). Since some people are spending lot of time to reduce VM boot time, it might be worth considering.
Thanks Philippe's comments.
Do you think it should be written to below[1]? right?
[1]:
if (vms->ras && acpi_ged_state)
No, as:
if (vms->ras) {
AcpiGedState *acpi_ged_state;
acpi_ged_state = ACPI_GED(object_resolve_path_type("",
TYPE_ACPI_GED, NULL));
if (acpi_ged_state) {
acpi_add_table(table_offsets, tables_blob);
...
Maybe I'm wrong and there is not much impact in VM boot time here,
reviews welcomed :)
