ACPI_WMI(4)						 BSD/i386 Kernel Interfaces Manual					       ACPI_WMI(4)

NAME

     acpi_wmi -- ACPI to WMI mapping driver

SYNOPSIS

     To compile this driver into the kernel, place the following line in your kernel configuration file:

	   device acpi_wmi

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   acpi_wmi_load="YES"

DESCRIPTION

     The acpi_wmi driver provides an interface for vendor specific WMI implementations (e.g. HP and Acer laptops).  It creates /dev/wmistat, which
     can be read to get information about GUIDs found in the system.

FILES

     /dev/wmistat  WMI status device.

     # cat /dev/wmistat GUID				      INST EXPE METH STR EVENT OID {5FB7F034-2C63-45E9-BE91-3D44E2C707E4}   1 NO   WMAA NO

NAME

     acpiwmi -- Windows Management Instrumentation support for ACPI

SYNOPSIS

     acpiwmi* at acpi?
     acpiwmibus* at acpiwmi?
     wmidell* at acpiwmibus?
     wmieeepc* at acpiwmibus?
     wmihp* at acpiwmibus?
     wmimsi* at acpiwmibus?

DESCRIPTION

     The acpiwmi device driver provides an ACPI interface for Windows Management Instrumentation (WMI).  The ACPI WMI interface is typically used
     to support vendor specific features found in various laptops.

     The following WMI mappings are supported:

	   wmidell   Dell laptops

	   wmieeepc  Some models of Asus Eee PC

	   wmihp     Hewlett-Packard laptops

	   wmimsi    MSI laptops

     The functionality varies from vendor to vendor.  Typically the interface is used for function and hotkey handling, but additional features
     may be present.

HISTORY

     The acpiwmi device driver appeared in NetBSD 6.0.

AUTHORS

     Jukka Ruohonen <jruohonen@iki.fi> wrote acpiwmi and most of the mappings.

CAVEATS

     While WMI should provide a certain degree of portability across laptop models from a particular vendor, there is no guarantee that the map-
     pings are functional in all models.

     The wmihp driver may conflict with hpqlb(4).
