* Move hp_accel to drivers/platform/x86Jean Delvare2011-03-211-146/+0
| | | | | | | | | | | | | The hp_accel driver isn't a hardware monitoring driver, so it doesn't belong to drivers/hwmon. Move it to drivers/platform/x86, assuming HP doesn't ship non-x86 laptops.

* trivial: doc: hpfall: accept disk device to unload as argumentFrans Pop2009-09-211-3/+42
| | | | | | | | | | | | | Allows users who use an IDE driver for their disk to use hpfall without having to modify the source. By default /dev/sda is used. Suggested by Christian Thaeter in http://lkml.org/lkml/2009/3/25/505. While we're add it, improve error message if opening /dev/freefall fails.

* trivial: doc: hpfall: reduce risk that hpfall can do harmChristian Thaeter2009-09-211-0/+8
| | | | | | | | | | | | | | | | | | | | | Improve the example code to be at least useable, as in not causing harm (as shown below). Code can still be improved further, but this adds some basic safeguards. 1. hpfall *MUST* mlockall(MCL_CURRENT|MCL_FUTURE); itself! Since the Program sits and waits most of the time it becomes very likely swapped out. If it gets woken up when the laptop drops from the table while it is swapped out it actually triggers harddrive activity! 2. Daemonize hpfall using 'daemon(0,0)' (quick and dirty). 3. Give hpfall realtime priority. Should give a chance that it has less latency when woken up.

* trivial: cleanup hpfall example code (checkpatch)Frans Pop2009-09-211-33/+31
| | | | | | | | | | | | | | | | | This patch makes hpfall.c conform to kernel coding style. I have not fixed the C99 // comments on two lines as they help indicate that those are not actually comments but incomplete code.

* hp accelerometer: add freefall detectionPavel Machek2009-02-181-0/+101
This adds freefall handling to hp_accel driver. According to HP, it should just work, without us having to set the chip up by hand. hpfall.c is example .c program that parks the disk when accelerometer detects free fall. It should work; for now, it uses fixed 20seconds protection period.
