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_PCI_FIXUP     Enable ACPI-based PCI interrupt routing fixup.  If
                           you have PCI interrupt related problem, try this
                           option.

        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 debugging.

HISTORY

     The acpi driver appeared in NetBSD 1.6.


BUGS

     Most of the ACPI power management functionalities are not implemented.
