No module containing the symbol 'drm_privacy_screen_register' found in

During the initial ramdisk environment creation process, I see this WARNING:

[myhost ~ ] >sudo mkinitcpio -k 6.12.0 -g /boot/initramfs-6.12.0-x86_64x.img

Some modules are missing?

Re: No module containing the symbol 'drm_privacy_screen_register' found in

Do you have the kernel from [core-testing] installed or the one from aur/linux-mainline? This is most likely due to uncompressed modules and should already be fixed (by me hehe) in mkinitcpio mainline: https://gitlab.archlinux.org/archlinux/ … e0f159efd3

kernel.org does not provide built kernels that I know of. Do you mean built a kernel from the source you obtained from kernel.org. If so does the kernel you built use modules and if so so are they compressed by default and is DRM_PRIVACY_SCREEN
enabled in your kernels config?

Yes, i built from the source i obtained from kernel.org.
Excuse me but i don't know if DRM_PRIVACY_SCREEN is enabled in my kernels config!
How can i verify or set it?!
Thanks in advance

Re: No module containing the symbol 'drm_privacy_screen_register' found in

To search the config of the running kernel

zgrep CONFIG_DRM_PRIVACY_SCREEN /proc/config.gz
zgrep CONFIG_MODULE_COMPRESS /proc/config.gz

If you are not running that kernel but have the source used for the build you can use grep instead of zgrep and replace /proc/config with /path/to/your/kernel/build/.config.

Thanks!
So the warning disappears with the next mkinitcpio release?

Yes with the new mkinitcpio release of if you use module compression of some sort
