Hi,

Looping in debian-kernel@, context being missing touchpad support on an
amd64 machine, unless an extra module is added to the installer.

Feel free to steal the bug report away from us and adjust debian/installer/modules as you see fit!

I've built a custom installer and `pinctrl-meteorlake` does the trick.
With this additional kernel module the touchpad works in the graphical installer.

Checking linux.git, it seems pinctrl modules are only shipped in udebs
for a single arch:

kibi@tokyo:~/debian-kernel/linux.git (debian/6.12/trixie <)$ git grep pinctrl -- debian/installer/
debian/installer/modules/arm64/kernel-image:drivers/pinctrl/**

I'm not sure how many pinctrl modules would make sense to ship, or in
which udeb, for other architectures.

Looking at the amd64 config, the modular ones are:

CONFIG_PINCTRL_ALDERLAKE=m
CONFIG_PINCTRL_CS42L43=m
CONFIG_PINCTRL_ELKHARTLAKE=m
CONFIG_PINCTRL_EMMITSBURG=m
CONFIG_PINCTRL_INTEL_PLATFORM=m
CONFIG_PINCTRL_JASPERLAKE=m
CONFIG_PINCTRL_LAKEFIELD=m
CONFIG_PINCTRL_METEORLAKE=m
CONFIG_PINCTRL_METEORPOINT=m

while the built-in ones are:

CONFIG_PINCTRL_AMD=y
CONFIG_PINCTRL_BAYTRAIL=y
CONFIG_PINCTRL_CHERRYVIEW=y
CONFIG_PINCTRL_INTEL=y
CONFIG_PINCTRL_BROXTON=y
CONFIG_PINCTRL_CANNONLAKE=y
CONFIG_PINCTRL_CEDARFORK=y
CONFIG_PINCTRL_DENVERTON=y
CONFIG_PINCTRL_GEMINILAKE=y
CONFIG_PINCTRL_ICELAKE=y
CONFIG_PINCTRL_LEWISBURG=y
CONFIG_PINCTRL_SUNRISEPOINT=y
CONFIG_PINCTRL_TIGERLAKE=y

Can you double-check if https://salsa.debian.org/kernel-team/linux/-/merge_requests/1530 make
sense to you?

If yes, feel free to reassign it to src:linux. And then we should mark
it as well as to be backported for 6.12.y for trixie.

Salvatore

Hi,

Roland Clobus <[email protected]> (2025-05-29):

Looking at this MR, I'm wondering where the required kernel modules
for d-i should be listed.

The list in `debian/installer/modules/amd64/kernel-image`
(kernel-team/linux) is rather short.
Recently we discussed adding i915 and a few of its dependencies, which are not listed here, but somewhere else [1].

The kernel-image udeb is used everywhere. i915, *if* it is to be added somewhere, does *not* belong there. See other files in that directory, fb-modules might make sense, speakup-modules might as well.

I'd prefer not touching the kernel udebs at the moment (for the i915
thing, which really is orthogonal to this bug report and this MR). We can add/remove things autonomously through the debian-installer source
package, and I really don't want to have through linux source uploads to
adjust stuff, especially given the amount of blur currently surrounding firmware-sof-signed vs. firmware-intel-sound…

If yes, feel free to reassign it to src:linux. And then we should mark
it as well as to be backported for 6.12.y for trixie.

That would look good to me (at least given the current state of things on
the arm64 side). If pinctrl were only about touchpads and stuff, one
could argue they only make sense for the graphical installer, but I
suppose this could control other internal stuff, so adding the whole
series of pinctrl modules, in kernel-image, might be the easiest.

The MR adds pinctrl/intel/* but what about
pinctrl/cirrus/pinctrl-cs42l43.ko.xz which is enabled by CONFIG_PINCTRL_CS42L43=m and was mentioned by Cyril in the duplicate bug #1104057 [1] ?
