DESCRIPTION

     NetBSD provides machine-independent bus support for ACPI devices and
     includes several ACPI device drivers.

     The NetBSD implementation of ACPI integrates Intel's ACPI Component
     Architecture (aka ACPI-CA) for the OS-independent part.  The ACPI-CA pro-
     vides OS-neutral ACPI functionalities such as ACPI BIOS table support, an
     ACPI event framework and an AML (ACPI Machine Language) interpreter.

     Options:

        ACPI_DEBUG                   Enable ACPI debugging message outputs.

        ACPI_ACTIVATE_DEV            Determine if the ACPI driver should
                                     attempt to activate inactive devices.
                                     The default is off.

        ACPICA_PEDANTIC              Force strict conformance to the ACPI
                                     specification in the ACPI-CA.  Do not
                                     enable this option unless you are debug-
                                     ging.

        ACPI_DSDT_OVERRIDE           Force a given DSDT instead of the BIOS-
                                     supplied version.  Use ACPI_DSDT_FILE to
                                     specify a DSDT.

        ACPI_DSDT_FILE="filename"    If ACPI_DSDT_FILE is not specified,
                                     default to ``dsdt.hex'' in the build
                                     directory.

BUGS

     Most of the ACPI power management functionalities are not implemented.
