I think that we must copy some files local file system to the kernel source code.

In your tutorial you specified the word INTO.

Now my question is which files are to be copied from local file system to the kernel source code.

I have specified this word because it is technical not quite correct. Yes, the fiirmware files (and also the CPU microcode) are part of the kernel IMAGE ... but not IN the kernel.

Okay ... you dont want to read this:
https://wiki.gentoo.org/wiki/User:Pietinger/Tutorials/Manual_kernel_configuration#Before_you_start
so I must tell you:
1. Boot your computer with our GentooLiveCD (either CD or copied to USB stick)
2. Change with CTRL-ALT-F1 to the console (and login as root)
3. do this command: dmesg | grep "Loading firmware"

For my INTEL system I have:
Code:
# dmesg | grep "Loading firmware"
[    8.895831] Loading firmware: i915/adls_dmc_ver2_01.bin
[    8.910450] Loading firmware: i915/tgl_guc_70.bin
[    8.910552] Loading firmware: i915/tgl_huc.bin
[   14.504934] Loading firmware: rtl_nic/rtl8125b-2.fw
# grep "EXTRA_FIRMWARE" /usr/src/linux/.config
CONFIG_EXTRA_FIRMWARE="i915/adls_dmc_ver2_01.bin intel-ucode/06-b7-01 rtl_nic/rtl8125b-2.fw i915/tgl_guc_70.bin i915/tgl_huc.bin"
CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware"

If you ask who (or how) copies this files "INTO" the kernel IMAGE, the answer is: This is done automatically when you compile the kernel with "make".

Is it possible to run dmesg directly in the current Gentoo Linux.

At present I have Fedora 41 Live image so can I use it to obtain the modules loaded information.

If you say no then I must download Gentoo Linux live image and make usb and boot into it and run the commands you specified.

rupeshforu3,

If your running kernel lists firmware as it's loaded, that is all that's needed.
Check your dmesg.
If not, you need a kernel that does.
