IBM Active Protection System Approach

[m.ehinger at ltur.de]

Hi,

what would be the best approach to implement aps on FreeBSD?

I got an Accelerometer driver which will deliver data. First Version is available at
https://sourceforge.net/project/showfiles.php?group_id=138242&package_id=160977

We have to poll the device for information quiet often to detect a possible shock early enough to park disk drive heads.
What else must be done to prevent a possible data loss?

There is also an discussion about that concerning linux.
http://sourceforge.net/mailarchive/forum.php?forum=hdaps-devel


Would an daemon be sufficient for that? Reaction time? What about an kernel thread?

Other solutions?

thanks in advance

Maik
