Re: NVidia Multitouch driver.

Hi Ikbel, hi Varun,

Benjamin and I are actually working on an Android-specific version of the multitouch drivers, until the time when Android (perhaps 3.0 Honeycomb) uses multitouch Protocol B. If you give us more details about this driver we might be able to combine our efforts.

Cheers,

St.

Got it. I will try to get these changes pushed upstream.

Support for multiple fingers is completely touch panel driven. We have
successfully verified
than 10 fingers also work fine on Android with another touch panel.

Do you mean to say there are certain things missing in the touch driver?
What do you mean by the last linux kernel?
I have found that patch by chance because I haven't seen it sent to
linux-input ml (which what is the std)
I just want it to get pushed to the mainline linux kernel as it is the
upstream of all linux distributions and for the android linux kernel
tree itself.

I just don't like to see only android getting drivers patches as it
can be seen as an action of forking the main kernel.

You can rebase the patch to the last tree and get help and feedback
from other developers for its integration. Company support of its own
drivers is very appreciated here.


And when analyzing the code I got a question. Does the nvodm hw
supports only 2 fingers or it's only caused by android limitation ?
Can the hw report more than 2 fingers ? (4 for example)

Thanks

i
