Hi,
I've had Nikola Nikolov test my touchpad code for me and got the report that the driver worked, but only when he passed i8042.noloop=1 and psmouse.proto=bare to the kernel. Now I have been pretty careful to keep your previous patch in place when writing my code. So, I'd like to further debug this issue, but I don't really understand the matter.
Especially, what is that AUX LOOP command that is disabled by noloop=1? Your patch does not have anything to do with that option, does it?
WRT passing noloop that laptop has a weird i8042 implementation where the kernel does not detect the aux port at all unless noloop is passed, a patch to do this automatically is already upstream:
WRT needing to pass psmouse.proto=bare, that should not be necessary with recent kernels, but the fix for this has only gone upstream very recently, so likely he is just using a somewhat older kernel.
Regards,
Hans
