RE: Dell XPS 13 9310: PNP: DLL0991 PNP0f13 supports different bus

So, Debian’s linux-image-5.9.0-2-amd64 selects that option now.

     $ grep TIGERLAKE /boot/config-5.9.0-2-amd64
     CONFIG_PINCTRL_TIGERLAKE=y
     CONFIG_SND_SOC_SOF_TIGERLAKE_SUPPORT=y
     CONFIG_SND_SOC_SOF_TIGERLAKE=m

There is nothing in `dmesg`, and as it’s builtin

     $ /sbin/modinfo pinctrl_tigerlake
     name:           pinctrl_tigerlake
     filename:       (builtin)
     license:        GPL v2
     file:           drivers/pinctrl/intel/pinctrl-tigerlake
     description:    Intel Tiger Lake PCH pinctrl/GPIO driver
     […]

there are the files below in /sysfs:

     $ ls /sys/bus/platform/drivers/tigerlake-pinctrl
     bind  INT34C5:00  uevent  unbind

Looks like it's working to me in your logs.

But the psmouse/synaptics message is still there:

quoted

[    1.611005] psmouse serio1: synaptics: Your touchpad (PNP: DLL0991

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.

This is expected behavior.  The hardware supports 2 buses.
The psmouse driver doesn't know whether or not the other drivers worked properly.

Please find the output of `dmesg` attached.

As a thought to generally improve things for such new hardware, would
you consider diffing the configs between Ubuntu and Debian?  I wonder
if there is anything else missing.

Yes, I’ll do that too.


Kind regards,
