54 * ACPI_DEBUG_OUTPUT - This switch enables all the debug facilities of the
55 * ACPI subsystem. This includes the DEBUG_PRINT output
56 * statements. When disabled, all DEBUG_PRINT
57 * statements are compiled out.
59 * ACPI_APPLICATION - Use this switch if the subsystem is going to be run
60 * at the application level.
65 * OS name, used for the _OS object. The _OS object is essentially obsolete,
66 * but there is a large base of ASL/AML code in existing machines that check
67 * for the string below. The use of this string usually guarantees that
68 * the ASL will execute down the most tested code path. Also, there is some
69 * code that will not execute the _OSI method unless _OS matches the string
70 * below. Therefore, change this string at your own risk.
