|
.Nm acpi_wmi
|
|
.Nd "ACPI to WMI mapping driver"
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following line in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device acpi_wmi"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
acpi_wmi_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides an interface for vendor specific WMI implementations
|
|
(e.g. HP and Acer laptops).
|
|
It creates /dev/wmistat%d, which can be read to get
|
|
information about GUIDs found in the system.
|
|
.Sh FILES
|
|
.Bl -tag -width /dev/wmistat%d -compact
|
|
.It Pa /dev/wmistat%d
|
|
WMI status device.
|
|
.El
|
|
.Sh SYSCTLS
|
|
The following sysctl node is currently implemented:
|
|
.Bl -tag
|
|
.It Va dev.acpi_wmi.%d.bmof
|
|
Managed Object Format (MOF) blob.
|
|
You can obtain human readable output by bmf2mof in bmfdec tool.
