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. sysctl support Two sysctl(8) settings are especially relevant for acpi: hw.acpi_supported_states and machdep.acpi_vbios_reset. hw.acpi_supported_states is a list of the supported states (see sysctl(7)). machdep.acpi_vbios_reset defines the handling of the graph- ics card. The supported values for this are: 0 No attempt to reset the VGA controller is done. 1 Call the VGA BIOS when still in real mode. This can result in direct reboots. In that case, use `2' or vbetool post from the pkgsrc/sysutils/vbetool package. 2 Call the VGA BIOS using the in-kernel x86 emulator.
