[solved]intel-ucode using refind and manual stanzas

I just did tried to configure refind to load the intel-ucode.img using manual stanzas. But it seems refind ignores it.
Here's my stanza in refind.conf:

menuentry Arch {
	icon EFI/refind/next-theme/icons/os_arch.png
	volume ArchRoot
	loader boot/vmlinuz-linux
	initrd boot/intel-ucode.img
	initrd boot/initramfs-linux.img
	options "root=UUID=410c637f-c414-4a60-bb4a-b4868f511883 rw  quiet acpi_osi= resume=UUID=70e18a0b-47c9-44fe-b8cb-93f3d6450120 rootflags=discard,data=ordered,relatime,rw"
}
% dmesg |grep microcode
[    0.428072] microcode: CPU0 sig=0x306c3, pf=0x10, revision=0x12
[    0.428078] microcode: CPU1 sig=0x306c3, pf=0x10, revision=0x12
[    0.428086] microcode: CPU2 sig=0x306c3, pf=0x10, revision=0x12
[    0.428092] microcode: CPU3 sig=0x306c3, pf=0x10, revision=0x12
[    0.428139] microcode: Microcode Update Driver: v2.00 <tigran@aivazian.fsnet.co.uk>, Peter Orub

This looks like the initrd wasn't loaded because no microcode was updated.

Don't know if it would appear here if it worked but at least the initrd option isn't on the kernel cmdline:

% cat /proc/cmdline
\boot\vmlinuz-linux root=UUID=410c637f-c414-4a60-bb4a-b4868f511883 rw  quiet acpi_osi= resume=UUID=70e18a0b-47c9-44fe-b8cb-93f3d6450120 rootflags=discard,data=ordered,relatime,rw initrd=boot\initramfs-linux.img

This all looks like refind only accepts the last definition of initrd overwriting the previous rather than adding these two.
Am I doing something wrong? Is it a bug(or missing feature?)
Is there any workaround?

Don't know if it's any help but there's a pretty good discussion at this thread;

Arch Linux is suited to the competent user.
Which ranks me right up there at highly incompetent.

Re: [solved]intel-ucode using refind and manual stanzas

Dice,

Same for me:

cat /proc/cmdline                                                                                                                                                                                  
\vmlinuz-linux root=UUID=046d22b7-f702-4fcf-8899-6d36ed3b1241 rootfstype=ext4 ipv6.disable_ipv6=1 acpi_backlight=vendor quiet rw initrd=initramfs-linux.img

In spite of adding the call to the new initrd prior to the initrd for initramfs-linux.img into the stanza :

menuentry "Arch Linux" {
		icon efi/EFI/refind/next-theme/icons/os_arch.png
		loader vmlinuz-linux
                initrd intel-ucode.img
		initrd initramfs-linux.img
		options "root=UUID=046d22b7-f702-4fcf-8899-6d36ed3b1241 rootfstype=ext4 ipv6.disable_ipv6=1 acpi_backlight=vendor quiet rw"
		ostype Linux
        submenuentry "Boot to Terminal/TTY" {
        options "root=UUID=046d22b7-f702-4fcf-8899-6d36ed3b1241 rootfstype=ext4 systemd.unit=multi-user.target rw"
        }
        submenuentry "Boot to Single-User Mode" {
        options "root=UUID=046d22b7-f702-4fcf-8899-6d36ed3b1241 rootfstype=ext4 systemd.unit=rescue rw"
        }
        submenuentry "Boot Arch Linux via GRUB" {
        loader efi/EFI/grub/grubx64.efi
        initrd
        options
        }
}

My guess is a limitation in the current version of refind.

Re: [solved]intel-ucode using refind and manual stanzas

I too am trying to make this work and failed so far.

If the refind stanza parser converts initrd xxx into
vmlinux-linuz initrd=xxx

then it is "possible" tho you'd need to test that
initrd "intel-ucode.img initrd=initramfs-linux.img"

just might work if it passes everything in qoutes down to kernel command line.

        submenuentry "Boot Arch Linux via GRUB" {
        loader efi/EFI/grub/grubx64.efi
        initrd
        options
        }
}

My guess is a limitation in the current version of refind.

What if the two initrd files are defined in the options line instead of the main part of the stanza?

i.e. change your config file to be:

menuentry "Arch Linux" {
		icon efi/EFI/refind/next-theme/icons/os_arch.png
		loader vmlinuz-linux
		options "root=UUID=046d22b7-f702-4fcf-8899-6d36ed3b1241 initrd=intel-ucode.img initrd=initramfs-linux.img rootfstype=ext4 ipv6.disable_ipv6=1 acpi_backlight=vendor quiet rw"
		ostype Linux
        submenuentry "Boot to Terminal/TTY" {
        options "root=UUID=046d22b7-f702-4fcf-8899-6d36ed3b1241 initrd=intel-ucode.img initrd=initramfs-linux.img rootfstype=ext4 systemd.unit=multi-user.target rw"
        }
        submenuentry "Boot to Single-User Mode" {
        options "root=UUID=046d22b7-f702-4fcf-8899-6d36ed3b1241 initrd=intel-ucode.img initrd=initramfs-linux.img rootfstype=ext4 systemd.unit=rescue rw"
        }
        submenuentry "Boot Arch Linux via GRUB" {
        loader efi/EFI/grub/grubx64.efi
        initrd
        options
        }
}

It is just possible that the options section may be parsed like the lines in refind_linux.conf whereas the main part of the stanza may be parsed differently and only take the last of the two lines that have "initrd xxxxx"?

Might be worth trying?

Re: [solved]intel-ucode using refind and manual stanzas

It works now. I appended the initrd=boot/intel-ucode.img to the end of the options line.
So the stanza looks like this:

menuentry Arch {
	icon EFI/refind/next-theme/icons/os_arch.png
	volume ArchRoot
	loader boot/vmlinuz-linux
	initrd boot/initramfs-linux.img
	options "root=UUID=410c637f-c414-4a60-bb4a-b4868f511883 rw  quiet acpi_osi= resume=UUID=70e18a0b-47c9-44fe-b8cb-93f3d6450120 rootflags=discard,data=ordered,relatime,rw initrd=boot/intel-ucode.img"
}

Microcode is updated now:

% dmesg |grep microcode
[    0.000000] CPU0 microcode updated early to revision 0x1c, date = 2014-07-03
[    0.145233] CPU2 microcode updated early to revision 0x1c, date = 2014-07-03
[    0.425814] microcode: CPU0 sig=0x306c3, pf=0x10, revision=0x1c
[    0.425821] microcode: CPU1 sig=0x306c3, pf=0x10, revision=0x1c
[    0.425828] microcode: CPU2 sig=0x306c3, pf=0x10, revision=0x1c
[    0.425835] microcode: CPU3 sig=0x306c3, pf=0x10, revision=0x1c
[    0.425878] microcode: Microcode Update Driver: v2.00 <tigran@aivazian.fsnet.co.uk>, Peter Oruba

Therefore this is solved I guess.

Re: [solved]intel-ucode using refind and manual stanzas

Dice,

Your suggestion on appending the microcode initrd to the options line works here too.

Thank you for posting this.

Re: [solved]intel-ucode using refind and manual stanzas

My system is not loading intel-ucode.img from the initrd line, either. However, it does not have an options line, it has options on the linux line. Is it ok to try adding it, there? (This is in grub2).

See https://wiki.archlinux.org/index.php/Microcode#Grub for the current advice for grub.
