Re: The Kernel knows. But how ? Did the acpi make a secret dead drop ?

Hi,

The subject line might be a bit dramatic, but I assure you my question is isn't.

I have a 3-axis accelerometer (LIS3LV02DL) in my laptop which shows up as an input device. Since its x86, I am assuming the necessary information was encoded in ACPI Tables. But I cannot find any mention of this device in the acpi tables exposed by the kernel.

Odds are it is an i2c device, that's the way it normally is hooked up on a laptop, not through ACPI as you have noticed. Does that help? greg k-h
