Detailed Description

ATARE - ACPI table IRQ routing extraction.

This extends the ideas from "ATARE: ACPI Tables and Regular Expressions, Bernhard Kauer, TU Dresden technical report TUD-FI09-09, Dresden, Germany, August 2009".

State: testing Features: direct PRT, referenced PRTs, exact name resolution, Routing Entries
