HDAPS

HDAPS - IBM Active Protection System Linux Driver

This is the Linux driver for the IBM Active Protection System.

Features

• prints accelerometer values
• uses userspace tool to park HD

Project Homepage / Availability

• Project Homepage
• The driver is included in the 2.6-mm series of kernels since August, 26th 2005.
• The driver is now in the mainline (2.6.14).

Status

A driver is included in recent Linux kernels and is actively maintained. However, presently the driver only enables reading of the acceleration data; it does not perform automatic disk head parking. The latter feature is under development. But there are already some useful applications for HDAPS, using the /sys interface it provides. See below.

Applications

Security & Safety

• disk park patch an experimental patch for parking the disk
• disk park patch adapted for the t41p model kernel 2.6.14 (capability detection disabled)
• disk park patch adapted for the t41p model kernel 2.6.15 (capability detection disabled)
• Script for theft alarm using HDAPS

Monitoring

• gkhdaps a GKrellM applet displaying tilt data
• gnome-tilt a gnome applet showing tilt data

Visualisation

• hdaps-gl a little app animating a 3D-ThinkPad
• hdapsgl-applet a GNOME applet animating a 3D-ThinkPad
• wmadhps a WindowMaker DockApp animating a 3D-ThinkPad
• OpenGL gyroscope hack keeps your display levelled when tilting the ThinkPad
