[PATCH] Input: ALPS - Detect trackstick presence for v7 protocol

[PATCH] Input: ALPS - Detect trackstick presence for v7 protocol

[Pali Rohár]

This patch adds detection of trackstick for v7 protocol devices. Code in this
patch is used in official Dell touchpad linux drivers for Dell models:
Dell Latitude E5250/5250, E5450/5450, E5550/5550

Detection code and base reg for alps v3 rushmore and v7 devices is exacly same.

Also user in bug https://bugzilla.kernel.org/show_bug.cgi?id=94801 reported
that Toshiba Sattellite Z30-A-1DG has only alps v7 touchpad device without
trackstick and kernel reports to userspace also redundant trackstick device.

Looks good, but has this been tested on a laptop which actually has a v7 pad +
trackstick? I would like to see this actually tested on at least one such
laptop before it gets merged.

I did not tested my patch on any v7 touchpad-only laptop.

But I guess Dell should have tested it... Of course we can wait 
until somebody test this patch and after that we will merge it.

@Santiago: Can you test this patch? You also have v7 touchpad 
only laptop (without trackstick).

Ah, but I'm not worried about testing on a touchpad-only laptop,
we are already reporting a trackpoint there even though there
is none. I'm worried about breaking existing v7 using laptops
which actually have a trackstick.

So if this is tested on a v7 laptop with trackstick, and it
does not break the trackstick then that is good enough for me.

Regards,

Hans

If you have another more powerful box you can always compile the kernel
there and then use "sshfs -o allow_others local_dir
remote_box:kernel/build/dir/" to mount the build directory on the target
box and do "cd local_dir; sudo make modules_install install" to install
the kernel.

Thanks.

Hello,

there should no functional changes (e.g. acceleration speed, 
etc.). And if yes, there is probably some side effect which 
should be investigated.

Please can you provide output from dmesg (grep for psmouse or 
input) and also output from lsinput?

That changed acceleration/speed sounds like psmouse fallbacks to 
some ImPS/2 relative protocol and not ALPS...

For me output/diff looks ok. Name is based on DUALPOINT flag 
which is cleared for non trackstick device version. And my patch 
adding that trackstick detection for v7.

I wonder if Masaki might have devices with V7 and trackstick available
and could test the patch for us?

Hello!

Alex now tested this patch on two Dell machines with ALPS: E5450 (with
TrackStick) and E5250 (without TrackStick).

With patch nothing was changed for E5450. And E5250 with patch does not
show trackstick input device anymore.

With that this patch looks good to me:

Reviewed-by: Hans de Goede <hdegoede@redhat.com>

Pali, it is probably a good idea to send Dmitry a v2 of these 2
patches rebased on top of the latest next and with Alex' Tested-By
and my Reviewed-by-s added.
