Installing a Kernel module.

Hello All,

So I am having a little problem in understanding why I am unable to
autoload a module in my image.

So I made modifications to
1. KCONFIG, MAKEFILE
2. Added a source and header file to driver/input/touchscreen
3. Added a file in /boot/arm/dts/overlays
4. Created a patch and added that patch in
/meta-raspberrypi-warrior/recipes/kernel/linux/linux-raspberrypi_4.19.bb
5. Added the overlay file in rpi_base.inc
6. In my local.conf added it under KERNEL_MODULE_AUTOLOAD_append

created the image without any issues. But after I install that Image I do
not see the module anymore?

Why Is that Am I missing something?

Hi Shravan,

as pointed out in the documentation [1], you need to specify   module_conf_*
and KERNEL_MODULE_PROBECONF.
Here is an example coming from one of my machine:

# g_multi: serial, RNDIS and sotrage over usbKERNEL_MODULE_PROBECONF
+= " g_multi"KERNEL_MODULE_AUTOLOAD += " g_multi"module_conf_g_multi =
"options g_multi file=/dev/mtdblock9"
