WARNING: Deprecated option 'ALL_microcode' found [SOLVED]

Hi, since new mkinitcpio update everytime when I

sudo mkinitcpio -p linux

I got this warning:

WARNING: Deprecated option 'ALL_microcode' found. Update '/etc/mkinitcpio.d/linux.preset' to use the 'microcode' hook instead.

Can someone please follow step by step instruction what I have to change in config files to fix this and don't broke initiation system?

Regards,
Slav

Re: WARNING: Deprecated option 'ALL_microcode' found [SOLVED]

I think you should do this:

A) Add "microcode" hook to /etc/mkinitcpio.conf after the "autodetect" hook
B) In /etc/mkinitcpio.d/*.preset remove the MICROCODE_ALL Line
C) Rebuild initramfs with
sudo mkinitcpio -P

But I would like a confirmation

Re: WARNING: Deprecated option 'ALL_microcode' found [SOLVED]

Maybe also remove line as
initrd /amd-ucode.img
or
initrd /intel-ucode.img
in /boot/loader/entries/

At least for systemd boot

Re: WARNING: Deprecated option 'ALL_microcode' found [SOLVED]

Thank you for quick answer, even have btfrs with snapshots come very carefully to modifiy something in sensitive initiation booting process, so decide to do this tomorrow evening (need a laptop for my job and will give update about progress.

in /boot/loader/entries/
have:

title Arch Linux
linux /vmlinuz-linux
initrd /initramfs-linux.img
options cryptdevice=UUID=d3dea46c-4f53-4ac4-95ca-a2856995ae41:root root=UUID=859c5edf-3011-4841-8a81-102dd837ca4f rootflags=subvol=@ quiet rw

so if I completely remove initrd /initramfs-linux.img does boot loader start?

Re: WARNING: Deprecated option 'ALL_microcode' found [SOLVED]

In /etc/mkinitcpio.d/linux.preset

have:

# mkinitcpio preset file for the 'linux' package

#ALL_config="/etc/mkinitcpio.conf"
ALL_kver="/boot/vmlinuz-linux"
ALL_microcode=(/boot/*-ucode.img)

PRESETS=('default' 'fallback')

#default_config="/etc/mkinitcpio.conf"
default_image="/boot/initramfs-linux.img"
#default_uki="/efi/EFI/Linux/arch-linux.efi"
#default_options="--splash /usr/share/systemd/bootctl/splash-arch.bmp"

#fallback_config="/etc/mkinitcpio.conf"
fallback_image="/boot/initramfs-linux-fallback.img"
#fallback_uki="/efi/EFI/Linux/arch-linux-fallback.efi"
fallback_options="-S autodetect"

so perhaps enough is to put # at front?
#ALL_microcode=(/boot/*-ucode.img)

Re: WARNING: Deprecated option 'ALL_microcode' found [SOLVED]

I removed All_microcode and added microcode hook after autodetect. I run btrfs/grub/luks2 with secure boot and successfully booted without issues or errors.

HOOKS=(systemd btrfs keyboard autodetect microcode modconf kms block sd-vconsole sd-encrypt filesystems fsck)

Re: WARNING: Deprecated option 'ALL_microcode' found [SOLVED]

1. /etc/mkinitcpio.conf  --- added in HOOKS section microcode

HOOKS=(base udev keyboard autodetect microcode modconf kms keymap consolefont block encrypt filesystems fsck)

2. hashed ALL_microcode

# /etc/mkinitcpio.d/linux.preset --- hashed line ALL_microcode

mkinitcpio preset file for the 'linux' package

#ALL_config="/etc/mkinitcpio.conf"
ALL_kver="/boot/vmlinuz-linux"
#ALL_microcode=(/boot/*-ucode.img)

PRESETS=('default' 'fallback')

#default_config="/etc/mkinitcpio.conf"
default_image="/boot/initramfs-linux.img"
#default_uki="/efi/EFI/Linux/arch-linux.efi"
#default_options="--splash /usr/share/systemd/bootctl/splash-arch.bmp"

#fallback_config="/etc/mkinitcpio.conf"
fallback_image="/boot/initramfs-linux-fallback.img"
#fallback_uki="/efi/EFI/Linux/arch-linux-fallback.efi"
fallback_options="-S autodetect"

3. rebuilding mkinitcpio by command:

mkinitcpio -p linux

4. restart sytems (Linux Arch + BTFRS + encyption + systemd-boot + timeshift)

All works perfect
Thank you guys
:-)

Re: WARNING: Deprecated option 'ALL_microcode' found [SOLVED]

I just backed up and removed all presets. They are automatically recreated via hook when reinstalling/updating a kernel. So in my case I needed to re-install linux and my other kernels and the files were rebuilt. ( code is in /usr/share/libalpm/scripts/mkinitcpio )

The only difference being the ALL_microcode line now missing in the new files. So doing it manually gives the same result.

I wonder why it was needed. Last time a change happened the files were recreated automatically.

Re: WARNING: Deprecated option 'ALL_microcode' found [SOLVED]

They are created automatically once -- on first installation of a kernel when not already existing. Afterwards recreating them would be problematic, since you can and are expected to adjust them if you want to change the defaults.
