Thanks.

Thanks for the reply.

It's not very easy to see. It's just a bit down from the link you sent. It's the last possible action in the Serialization Actions table:
https://uefi.org/specs/ACPI/6.5/18_Platform_Error_Interfaces.html#serialization-actions

18.5.1.1. Serialization Actions

GET_EXECUTE-_OPERATION_TIMINGS

Returns an encoded QWORD:
[63:32] value in microseconds that the platform expects would be the maximum amount of time it will take to process and complete an EXECUTE_OPERATION.
[31:0] value in microseconds that the platform expects would be the nominal amount of time it will take to process and complete an EXECUTE_OPERATION.

Can you give a reference to the ACPI spec where this timing information is documented? I'm looking at ACPI 6.5 and don't see anything about this.
