Linux/ACPI - DSDT: Overview This is just a short introduction to DSDTs, see the specification, chapter 2.1 for more info. DSDT is an acronym for Differentiated System Description Table. This table contains the Differentiated Definition Block, which supplies the information and configuration information about the base system. It is always inserted into the ACPI Namespace by the OS at boot time. Unfortunately, many hardware vendors and OEMs are not capable of supplying fully functional tables (not even the members of the ACPI SIG), see also the blacklist. So there is a need to patch these tables by us. :) By kfvdin Public bookmarkswith 2.1chapterdsdtsinfointroductionshortspecification
