I submitted normalized patches to Canonical Ubuntu in October for the
alps psmouse touchpad. The thread is long and confusing at
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/606238
Since then, I have maintained a psmouse dlkm that provides alps support
for a number of new systems, primarily from Dell.
Recently, I have been asked by several people to submit the patches to
linux-input to merge into the upstream kernel. I am looking for advice
on how to proceed. The big problems are:
1) The alps touchpads seem to be mutating relatively quickly with
several unrecognized signatures appearing over the last few months after
I built my patches.
2) A number of people have submitted a patch for a particular alps
touchpad signature, which will need to be reconciled and rolled-up into
a single driver. See the Jan 20 3-part submission by
cernekee@xxxxxxxxx. His patches look good, and clean up the code a good
bit, but target a touchpad signature also reverse-engineered by
bgarami.foss@xxxxxxxxx. I integrated the bgarami fixes into my patches
but the patches from cernekee@xxxxxxxxx are radically different.
3) I built the patches against the 3.2 kernel. My understanding is they
do not even compile against the kernel head - something like 3.5.x.
I feel bad submitting the patches I have. They are big and rough
because several of us reverse-engineered the ALPS interfaces but did not
try to figure them out. It will take a lot of merge+test work to
reconcile the patch submissions for the various alps target platforms.
What do you suggest I do (e.g. submit a patch for only the new protocol
I can test?)
