Hi Dmitry,

as far as I can see, there was no reply from you. If so, then I may have missed that, sorry for that.
As I said I am not aware of any issues when running the touchpad and trackpoint with RMI4. The only difference is the mentioned error message during shutdown, which I would like to get rid of, if possible.
Can the patch be merged? Anything missing for that?

Thanks and best
Dennis

Hi Dmitry,

thanks for your reply. In the following I just add the content of my first
email to this list:
#####
In dmesg I found the following:
psmouse serio1: synaptics: Your touchpad (PNP: LEN007a PNP0f13) says it can
support a different bus. If i2c-hid and hid-rmi are not used, you might want
to try setting psmouse.synaptics_intertouch to 1 and report this to linux-input@vger.kernel.org.


After setting psmouse.synaptics_intertouch=1, touchpad and trackpoint still
work fine. Also no problems with suspending my laptop.

The only problem is the following error meesage on shutdown:
rmi4_physical rmi4-00: Failed to read irqs, code=-6

/proc/bus/input/devices:
I: Bus=001d Vendor=06cb Product=0000 Version=0000

I: Bus=0011 Vendor=0002 Product=000a Version=0000
N: Name="TPPS/2 IBM TrackPoint"
P: Phys=rmi4-00.fn03/serio0/input0

U: Uniq=
H: Handlers=event19 mouse1
B: PROP=21
B: EV=7
B: KEY=70000 0 0 0 0
B: REL=3

Is there anything I can do, that the error messsage doesn't appear anymore?
Should I not use RMI?
#####

As far as I can see, there is no issue running the touchpad with RMI4. The
only difference to running it in PS/2 mode is the mentioned error message
during shutdown. Is that error message only cosmetic, or a real issue? Can
something be done to omit this error message?
Regarding the touchpad, is the above pasted information sufficient, or do
you need anything else?

Thanks and best
Dennis

Hi Dennis,

The Lenovo Thinkpad T470s I own has a different touchpad with
"LEN007a" instead of the already included PNP ID "LEN006c".

However,

my touchpad seems to work well without any problems using RMI. So this

patch adds the other PNP ID.

So there are no visible issues when running the touchpad in PS/2 mode
compared to RMI4? (Just trying to figure out if it needs to go into
stable releases).

Do you know what trackpoint does the device have? 

Thanks.
