Any thoughts |
It may not be relevant to this problem, but you should definitely activate this (statically):
| Code: | # CONFIG_INTEL_IOMMU_DEFAULT_ON is not set
# CONFIG_INTEL_IOMMU_SCALABLE_MODE_DEFAULT_ON is not set |
Because you have enabled one important module static into your kernel ...
| Code: | | CONFIG_HID_MULTITOUCH=y |
... you could try to do this with every necessary module - especially:
| Code: | CONFIG_I2C_HID=m
CONFIG_I2C_HID_ACPI=m |
If it does not work after these changes with kernel version 6.10.8, although it is recognized correctly with 6.10.6, then we have a kernel regression between these two versions and you can/should write a kernel bug report.

Happy to hear that. You are very Welcome !

No ... I have been configuring my kernels myself for 20 years and have gained a bit of experience in the process. I have learnt a lot from the knowledge and feedback from other users (e.g. what an i2c touchpad needs). I also visit this site regularly and read about new patches:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git
(just click on the respective branch; e.g. linux-6.10.y)
You have activated a lot of unnecessary modules in your kernel configuration. Possibly because you didn't know what you really needed. I guess compiling your kernel (make) takes 20 or 30 minutes (I compile my kernel in under a minute).
Once you have managed the effort of a manual kernel configuration (which is very large), you will hardly have any problems in the future, because you simply take over the configuration for new versions (make oldconfig).
I have tried to pass on some of the information in my wiki articles. Start here:

That's really cool, I wish to learn these skills too and recently just switched from arch to gentoo due to the idea of understanding more of what my system is.
| Code: | #!/bin/bash
# Check if the script is run as root
if [ "$(id -u)" != "0" ]; then
echo "This script must be run as root" 1>&2
exit 1
fi
# Set the kernel version
KERNEL_VERSION="6.10.8-gentoo-x86_64"
# Change to the Linux source directory
cd /usr/src/linux
make LSMOD=$HOME/.config/modprobed.db localmodconfig
# nvim .config
# Audio Patch
sed -i '/CONFIG_SND_HDA_INTEL=/c\CONFIG_SND_HDA_INTEL=m' /usr/src/linux/.config
sed -i '/CONFIG_SND_SOC_INTEL_SOUNDWIRE=/c\CONFIG_SND_SOC_INTEL_SOUNDWIRE=m' /usr/src/linux/.config
sed -i '/CONFIG_SND_SOC_SOF_ALDERLAKE=/c\CONFIG_SND_SOC_SOF_ALDERLAKE=m' /usr/src/linux/.config
# Compile the kernel
sudo make CC="ccache gcc" -j$(nproc) KCFLAGS="-O2"
# Install kernel modules
sudo make modules_install -j$(nproc)
# Install the kernel
sudo make install
# Rename the kernel image
cd /boot
sudo mv vmlinuz vmlinuz-$KERNEL_VERSION
# Generate the initramfs
sudo dracut --force --kver $KERNEL_VERSION /boot/initramfs-$KERNEL_VERSION.img
grub-mkconfig -o /boot/grub/grub.cfg || { echo "GRUB configuration update failed"; exit 1; }
# Clean up old kernels, keeping the 2 most recent
eclean-kernel -n 2 || { echo "Kernel cleanup failed"; exit 1; }
echo "Kernel compilation and installation complete."
|
so currently I got this working and it pretty much has a lot of it pruned but
~/.config/modprobed.db:
https://clbin.com/oaOZF
lsmod:
https://clbin.com/AX4G9
but when I run the localmodconfig those 3 lines I have where I am patching the kernel for the audio are impacted.
Any ideas? |

| One starting point in configuring your kernel is to run lspci -v and see what hardware yiu have on point bus. Yiu want every hardware to have a kernel driver assigned. If you have it under overconfigured module, you may have every driver in. Record them, this what you need to enable in the kernel and disable the rest. If some have no driver, Google with pciid what driver should support them. |

TBH I dont understand what you want to do with your commands, but I can tell you that CONFIG_SND_SOC_INTEL_SOUNDWIRE does not exist in the kernel. If you go into "make menuconfig" and then press / and then search for SND_SOC_INTEL_SOUNDWIRE the only result you will get is: CONFIG_SND_SOC_INTEL_SOUNDWIRE_SOF_MACH ...
Maybe read the last paragraph of this chapter:
https://wiki.gentoo.org/wiki/User:Pietinger/Tutorials/Manual_kernel_configuration#Basics
BTW: I am not a fan of modprobed.db ... I did it manually with booting (twice) a GentooLiveCD / UbuntuLiveCD and then asked with "lsmod" for all modules, and compared both lists ... and then decided what I want / what I need ... and what I dont want (Intel MEI  ).
(Note: I don't need an initramfs on my desktop either, because I have configured everything it needs in the kernel - on my notebook I only have a self-built initramfs because I do something very special there: ima_appraise=enforce.)
