R52 hdaps support?

R52 hdaps support?

[Keenan Pepper]

I recently splurged on a new ThinkPad R52 (because it was one of the few laptops 
in the store with /all/ linux-supported hardware), but the 2.6.14-rc1 kernel I 
just compiled says "hdaps: supported laptop not found".

Looking at the source I notice there's a whitelist of models that goes up to 
R51... How badly could it break if I just went ahead and added R52? Should it be 
"NORMAL" or "INVERT"?

Hi Keenan,

	We don't have the X42 nor the R52 in the list of supported laptops.
Please send an email to hdaps-devel@lists.sf.net so that we can do
something about adding your laptop to the dmi list.

Additionally, the X41 should be in the list of supported laptops
(Kconfig)

Thanks,

.Alejandro

The R52 should work and nothing should break.  If it works, I'll add it.

As for normal versus inverted: You probably want NORMAL, but you will
have to verify it and let me know.  You'll know you have the wrong one
when the readings are, well, inverted.

OK, it's compiled and running, but how do I tell if it's inverted? The laptop is 
on a horizontal surface and /sys/devices/platform/hdaps/position reads 
(482,508). What does that mean?

Well, you can use the joystick device and see that the axises are
correct.

The other thing would be to grab the pivot program from the hdaps
package at http://www.kernel.org/pub/linux/kernel/people/rml/hdaps/ and
run it.

Tilting the laptop to you run and toward you should be (positive,
positive) I think.

Keenan,

	You may try using the hdaps-gl located at the hdaps.sf.net download
section which will take you to the SF Repository.

Oh wow! That's really cool. And my R52 definitely works as "NORMAL", so you can 
go ahead and add it to the whitelist.

Done.  Will be in the next patch I send to Linus.

Robert,

	We have some laptops missing from the HDAPS list.
X41 and X42? (I think)

I added X41 in the patch I sent out today.

X42: I don't think I have ever gotten any reports.
