.Sh DESCRIPTION
|
|
.Nx
|
|
provides machine-independent bus support for
|
|
.Tn ACPI
|
|
devices and includes several
|
|
.Tn ACPI
|
|
device drivers.
|
|
.Pp
|
|
The
|
|
.Nx
|
|
implementation of
|
|
.Tn ACPI
|
|
integrates Intel's ACPI Component Architecture
|
|
(aka ACPI-CA) for the OS-independent part.
|
|
The ACPI-CA provides
|
|
OS-neutral ACPI functionalities such as ACPI BIOS table support,
|
|
an ACPI event framework and an AML (ACPI Machine Language) interpreter.
|
|
.Pp
|
|
Options:
|
|
.Bl -tag -width ACPI_DSDT_FILE__filename_XX -offset 3n
|
|
.It Dv ACPI_DEBUG
|
|
Enable ACPI debugging message outputs.
|
|
.It Dv ACPI_ACTIVATE_DEV
|
|
Determine if the ACPI driver should attempt to activate
|
|
inactive devices.
|
|
The default is off.
|
|
.It Dv ACPICA_PEDANTIC
|
|
Force strict conformance to the ACPI specification in the
|
|
ACPI-CA.
|
|
Do not enable this option unless you are debugging.
|
|
.It Dv ACPI_DSDT_OVERRIDE
|
|
Force a given DSDT instead of the BIOS-supplied version.
|
|
Use
|
|
.Dv ACPI_DSDT_FILE
|
|
to specify a DSDT.
|
|
.It Dv ACPI_DSDT_FILE="filename"
|
|
If
|
|
.Dv ACPI_DSDT_FILE
|
|
is not specified, default to
|
|
.Dq dsdt.hex
|
|
in the build directory.
