Build as a module #2

It would be great if this could be built as a module against existing kernel and replace the currently installed module.

Instructions/modifications to achieve this would be great.

Also, the asix patch can be removed since it's in mainline since rc7 -;a=commitdiff;h=e8303a3b2196272c3eb994d0fd1a189a958a2bdd


Once the driver has been submitted and accepted upstream the distro kernel maintainers should be willing to add the patch to their kernels even if it's not yet updated to the latest upstream version. I'm not going to create a Makefile for building standalone modules from my sentelic tree, as at least in Fedora the psmouse driver is not built as a module by default and you couldn't use the module with the stock kernel anyway. But I'll consider merging such a Makefile into my repo if you create one.

I've dropped the ASIX patch from my repo.



I found this

It works as it is given, but when I use the src files from this repo, I get this output.

How is this patch going regarding upstream submitting and acceptance? Is there anything we can do to encourage it?

Thanks for your work.


Any update here? I'd really like to finally use multitouch


Seems to be rolling on: #3 (comment)

Patching and building your own kernel isn't that difficult.


Unfortunately two finger scrolling doesn't work as well for me:


In my case, kernel 3.4 and this patch does exactly the same. Two-finger scrolling is buggy, edge scrolling isn't working and cursor jumps on the edges (issue #6)


What about without this patch?


Also, don't forget the other bug:


Without this patch (on older kernels) double-finger scrolling didn't work, edge scrolling also didn't work, but cursor wasn't jumping.


What about with the current kernel without this patch? I have discovered that with the vanilla kernel the two fingered tap interferes with two finger scrolling. If I disable one the other works as expected.


After applying v3 patch (and modifying one line as said in later comment) from kernel bugzilla, the cursor doesn't jump, two-finger vertical scrolling partially works (it usually scrolls but when i put finger up, it returns to original position) and edge scrolling doesn't work. Tried changing hscroll attribute in /sys/devices/platform/i8042/serio2, but it didn't do anything.
