|

.Nd HP 3D DriveGuard accelerometer
|
||||
.Sh SYNOPSIS
|
||||
.Cd "hpacel* at acpi?"
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
device driver supports accelerometers that are
|
||||
commonly available in Hewlett-Packard laptops.
|
||||
The supported chip is
|
||||
.Dv LIS3LV02DL
|
||||
from STMicroelectronics, although other chips from the same family, such as
|
||||
.Dv LIS3LV02DQ ,
|
||||
may also work, provided that that the vendor has implemented suitable
|
||||
.Dv ACPI
|
||||
access methods.
|
||||
.Pp
|
||||
The
|
||||
.Nm
|
||||
driver reports the acceleration readings of the X-, Y-, and Z-axis
|
||||
via the
|
||||
.Xr envsys 4
|
||||
.Tn API
|
||||
and the
|
||||
.Xr envstat 8
|
||||
command.
|
||||
.Sh SEE ALSO
|
||||
.Xr acpi 4 ,
|
||||

||||

.Re
|
||||
.Sh HISTORY
|
||||
The
|
||||
.Nm
|
||||
device driver appeared in
|
||||
.Nx 6.0 .
|
||||
.Sh AUTHORS
|
||||
.An Jukka Ruohonen
|
||||
.Aq jruohonen@iki.fi
|
||||
.Sh BUGS
|
||||
The used accelerometer chip is capable of generating wake-up,
|
||||
direction detection, and free-fall interrupts.
|
||||
In the ideal situation these could be used to evoke possible emergency action.
|
||||
However, the
|
||||
.Nm
|
||||
driver only reports the readings from the accelerometer via
|
||||
.Xr sysmon_envsys 9 .
