Talk:HDAPS

So, this is in the stable kernel now, but what userspace program do we need to actually park the heads? --MrStaticVoid 01:26, 30 Oct 2005 (CEST)

Yes the hdaps driver is in the 2.6.14 kernel, but support to park the heads quickly and freeze the disk queue (to prevent the heads from getting un-parked) is not. There is some disagreement into how that should be implemented.

In other words, the hdaps driver for the moment is rather useless, unless you want to use it to play games.

I head rumours that you can make SDL handle this like a joystick, e.g. for playing Neverball. Can anyone confirm or deny that? Thanx --Nomeata 01:16, 16 Nov 2005 (CET)

Yes it is possible to use it as a joystick, as Tonko allready mentioned. /dev/input/jsX modprobe joydev

Ozi

Thanks, I didn't have the joydev module. Rebuilding... --129.13.186.1 15:30, 16 Nov 2005 (CET)

Yeah, it's a pretty good party trick - set up the HDAPS joystick as xmame input. You can play Ms. Pac-man by tilting your laptop to make pac-man navigate the maze. You can imagine that the pac-man "rolls" downhill, just like those old wooden marble-puzzles that you see around. Heh, can actually clear a level or two.

Marble madness was strangely unsatisfying though, and just didn't work well (probably due to the diagonal nature of the screen in that game).

Anyone got the queue freezing patch running on 2.6.16? I'm going to try to manually merge it but didn't want to duplicate someone else's work.

I hawe a problem

I tray to start working my IBM x40 with hdaps function but I can't make it right. The main problem is in a not hanging variables when I read /sys/devices/platform/hdaps/position
