Hi; this seems to fail 'make check' (on an x86 host):

acpi-test: Warning! DSDT binary file mismatch. Actual
[aml:/tmp/aml-01P83Z], Expected [aml:tests/data/acpi/virt/DSDT].
acpi-test: Warning! DSDT mismatch. Actual [asl:/tmp/asl-4ZP83Z.dsl,
aml:/tmp/aml-01P83Z], Expected [asl:/tmp/asl-H7UE4Z.dsl,
assertion failed: (all_tables_match)
ERROR - Bail out!
assertion failed: (all_tables_match)
Aborted (core dumped)
recipe for target 'check-qtest-aarch64' failed

Is there a need to update the reference DSDT used by the test?
