Thanks steve_v

indeed trying to activate it (modprobe) as it's no longer a module, will definitly not work.

I've tried a zless /etc/config.gz and it works so recompiling the kernel worked

any ideas

Only the obvious: Read the documentation (or a good wiki). The module this option builds is not named 'ikconfig'.

And the blindingly obvious:

CONFIG_IKCONFIG=m y

Selecting 'y' will build the option into the kernel image, so there definitely won't be a module to load.

Aside, no idea why you would want IKCONFIG as a module anyway. There's sod-all to be saved by not including a copy of .config in the kernel, so you might as well build it in.

I recompiled the kernel with that change

CONFIG_IKCONFIG=m y
CONFIG_IKCONFIG_PROC=y

but still get

[SOLVED] modprobe ikconfig -> FATAL: Module ikconfig not found in directory

Hi,

I've cross-compiled a Linux kernel https://github.com/raspberrypi/linux (6.6.63)

with

CONFIG_IKCONFIG=m
CONFIG_IKCONFIG_PROC=y

but when I do modprobe ikconfig on the client, I get:

FATAL: Module ikconfig not found in directory /lib/modules/6.6.63-v8_TESTT+

I've launched depmod but the error remain.

tree -F -L 2 /lib/modules/6.6.63-v8_TESTT+

I don't know if /lib/modules/6.6.63-v8_TESTT+/build is required to load the module, as /tmp/RaspKernel6-6y/linux was actually in the host (cross-compile) and not on the raspberry..

Here the ~commands that I use to cross-compile the kernel

su
apt install bc bison flex libssl-dev make libc6-dev libncurses5-dev crossbuild-essential-arm64

cd /tmp/LinuxKernel/linux

git clone --depth=1 --branch rpi-6.6.y https://github.com/raspberrypi/linux

## applying the default configuration
cd linux
KERNEL=kernel8
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- bcm2711_defconfig
##

make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- menuconfig

make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- Image modules dtbs

## install the kernel modules onto the boot media:
env PATH=$PATH make -j12 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- INSTALL_MOD_PATH=/mnt/rasprootfs modules_install

cp arch/arm64/boot/Image /mnt/raspboot/$KERNEL.img
cp arch/arm64/boot/dts/broadcom/*.dtb /mnt/raspboot/
mkdir /mnt/raspboot/overlays
cp arch/arm64/boot/dts/overlays/*.dtb* /mnt/raspboot/overlays/
cp arch/arm64/boot/dts/overlays/README /mnt/raspboot/overlays/

If you have any ideas, I'm all ears..
