Re: [edk2-devel] [PATCH] MdePkg/Acpi64: Update Error Severity type for Generic Error Status Block

["Ni, Ray" <ray.ni@intel.com>]

The Acpixx.h are not like Pcixx.h. There are duplications among them (using different structure/macro prefix with version embedded).

I suggest we either update all of them, or we refactor the Acpixx.h to remove the duplications through "typedef" or "define".

The easier way for this small change can be just to update all duplicated code.

Thanks,
Ray

Hello Liming,

My take is that the consumers of the ACPI header file will always use the latest version.
Is my understanding correct? Or should I update all the header files relating to the affected versions (5.1~6.4) of the ACPI spec?

Best Regards,
Hao Wu
