Hi Rebecca,

Thanks for catching this.
I think we also need to add a check in Acpiview to report this issue. However, that would be another patch series.

Regards,

Sami Mujawar

The Revision field should probably be 2, not 1. ACPI 6.4 says:


2. This field also sets the global integer width for the AML
interpreter. Values less than two will cause the inter-
preter to use 32-bit integers and math. Values of two
and greater will cause the interpreter to use full 64-bit
integers and math.
