Hi!
It seems like Luca has one more whitelist entry... Pavel
Subject: axes conversion for hp compaq 8710w for HP_ACCEL linux kernel module From: Luca Cappa <lcappa@gmail.com>
Hello,
I have a laptop HP Compaq 8710W, I compiled into my kernel the LIS3LV02DL and HP_ACCEL module drivers. While loading it cannot recognize the laptop model, so i am sending the necessary information to update the database of Axes Orientations.
>When the laptop is horizontal the position reported is about 0 for X and Y >and a positive value for Z Yes, it is about 0,0,1000, the actual reading says: (-17,-26,1018);
> If the left side is elevated, X increases (becomes positive) Yes, X goes toward to positive 1000.
>If the front side (where the touchpad is) is elevated, Y decreases (becomes negative) No, Y goes toward to positive 1000.
>If the laptop is put upside-down, Z becomes negative Yes, the laptop on a table Z gives 1000, and if upsidedown the Z reads -1000.
So in few words the Y axis is inverted, I paste here below the very simple patch to configure properly the axis conversion. The patch is against the file hp_accel.c of 2.6.29-rc8, i.e. the one shown here:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=drivers/hwmon/hp_accel.c;h=29c83b5b96974bb88cbeb67d896ba46ee71469f2;hb=HEAD
Greetings, Luca
