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.
SUPPORTED DEVICES

devices:
