In Linux from scratch tutorials they said as follows.
Could you link to that please. I could not find it.

In this tutorial one line is
'Early loading of microcode' and cat all the Intel blobs to GenuineIntel.bin

microcode is not firmware unless you plan to patch the kernel to expect firmware files in the microcode bundles I would expect adding firmware to the microcode bundles to either break microcode updating or do nothing. https://www.kernel.org/doc/html/latest/ … ocode.html does say
The loader supports also loading of a builtin microcode supplied through the regular builtin firmware method CONFIG_EXTRA_FIRMWARE.
That does not mean the reverse is true and the microcode loader can handle firmware. As mkinitcpio supports globing why are you not using
FILES=(/usr/lib/firmware/rtlwifi/rtl8192eu_nic.bin.zst /usr/lib/firmware/amdgpu/*)Offline
In some Linux documentation they said that we must not use /usr/lib/firmware/amdgpu/*
Instead we must enter each and every file name with absolute path.

Please provide the link to that. You can achieve an expanded list with:
(FILES=$(echo /usr/lib/firmware/rtlwifi/rtl8192eu_nic.bin.zst /usr/lib/firmware/amdgpu/*);sed -r "s|^(FILES=\().?(\))$|\1$FILES\2|" -i /etc/mkinitcpio.conf)Offline
While reading Gentoo Linux kernel compile guide they suggested not to use global for CONFIG_EXTRA_FIRMWARE entry in kernel configuration file.
I thought it will be same for all the times.
Thanks for clarifying my doubts and I will follow what you have suggested.

CONFIG_EXTRA_FIRMWARE requirements do not match that of mkinitcpio or any of the other initrd generators Arch support. I suggest you use either add just the firmware files your current kernel needs and should those needs change they will be accompanied by failure to load firmware messages in dmesg or add the glob line.

Ok sure.

After adding the firmware to the initrd is the kernel loading the firmware from there or is the initrd loaded too late?

At present I am not compiling kernel source code because I am reading a book about
1) how grub, kernel boots
2) how initrd works
3) dracut
