Changes to Microcode Updates For Intel CPUs

---

Microcodes on Intel CPUs is no longer loaded automatically, as it needs to be loaded very early in the boot process. This requires manual adjustments in the bootloader. If you have an Intel CPU, please follow
[b:6hhpcnnx][the instructions in the Arch wiki[/url:6hhpcnnx].[/b:6hhpcnnx]

This will be taken care of for new installations within the next few days. Let us know if you have any questions!

Entonces usé la opción de bajarlo del mirror [b:3rezj83v](intel-ucode-20140913-1-any.pkg.tar.xz)[/b:3rezj83v], nos sé como instalarlo, así que lo descomprimí y me dió dos carpetas una que se llama [b:3rezj83v]boot[/b:3rezj83v] y que contiene [b:3rezj83v]intel-ucode.img[/b:3rezj83v] y la otra [b:3rezj83v]usr/share/licenses[/b:3rezj83v] la cual contiene [b:3rezj83v]intel-ucode[/b:3rezj83v].

[b:3rezj83v]Segundo paso:[/b:3rezj83v]
Grub
Tango-view-fullscreen.png This article or section needs expansion.
Reason: Instructions for grub are missing. (Discuss)
For the time being, you can manually add /intel-ucode.img in your grub.cfg as follows:
[…]
echo 'Loading initial ramdisk …'
initrd /intel-ucode.img /initramfs-linux.img
[…]
Remember that the path to /intel-ucode.img is relative to the boot partition, just as that of initramfs. This means that if you have a dedicated /boot partition you should use /intel-ucode.img; else use /boot/intel-ucode.img.
Es que no entiendo como ponerlo en el grub.cfg. A los moderadores, de antemano muchas gracias por su paciencia.

PD. tengo instalado KDE en una notebook HP 430 Intel Pentium CPU P6200 @ 2.133GHz

Hola,

Primero, la actualización es muy reciente, ahora mismo algunos mirrors aún no estan actualizados, pero algunos si lo estan. A mi me ha funcionado.

Prueba a ejecutar:

  
pacman -Syu  
pacman -S intel-ucode  

Para instalar un paquete que te has descargado no tienes que descomprimirlo, simplemente ejecuta:

pacman -U paquete.xz

El segundo paso es bastante chapuza, te dice de editar directamente el grub.cfg (cosa que no se recomienda, puesto que es un fichero que se genera automáticamente con grub-mkconfig).

Edita pues el grub.cfg (/boot/grub/grub.cfg) y añade /intel-ucode.img a la linea del initrd tal que así:

initrd /intel-ucode.img /initramfs-linux.img

Saludos!

Karasu

please provide instructions in english- the wiki wasn’t very helpful for me

Hi Max, I’ll translate my previous message hoping that it will help you. If you have more questions please just ask.

My previous post now in English:

Hi,

First, that update is recent, so some mirrors are not updated yet, but others are. I’ve tried and it worked here.

Try to update first your pacman db and then install the package:

  
pacman -Syu  
pacman -S intel-ucode  

Oh, to install a downloaded package you don’t have to decompress it, just run:

pacman -U package.xz

The second step is a bit of a botched job, as it tells you to edit the grub.cfg file (which in normal circumstances you should not do, as it’s an automatically generated file by the command grub-mkconfig).

So, edit the grub.cfg file (/boot/grub/grub.cfg) and just add /intel-ucode.img to the initrd line, so it looks like this:

initrd /intel-ucode.img /initramfs-linux.img

Cheers!

Thanks karasu!

karasu, are the 2nd and 3rd steps optional?

1st step worked, but 2nd resulted “error: ‘package.xz’: could not find or read package”, and for 3rd: “initrd /intel-ucode.img /initramfs-linux.img
bash: initrd: command not found”.

Thank you.

Hi the second “step” was something specific to the OP’s question. You only need to do the first step and the last step. The last one is not a command. You must edit your grub.cfg file, changing the initrd line to look like the example.

Cheers!

Hello can you explain what that do ? I don’t understand if I need to do it or not.

do you know if you have the haswell gpu?

Hi,

Run this command:[command:2d60niap]sudo sed -i ‘s%initrd\t/initramfs-linux\.img%initrd\t/intel-ucode\.img /initramfs-linux\.img%g’ /boot/grub/grub.cfg[/command:2d60niap]

Cheers!

no I don’t. I have an old Intel Pentium T4400.

Tutorial:

1. You need to update your pacman database and it will ask you to update packages which is fine, go ahead and do that.

sudo pacman -Syu

2. Now install the intel-ucode package.

pacman -S intel-ucode

3. The next step is to update the grub.xfg file to include ucode. The following command will open the file grub.cfg in gedit as root so you can edit it.

sudo gedit "/boot/grub/grub.cfg"

4. This file will have a lot of lines that were auto-generated by Grub. Search for the following, “initrd”. You will find two instances of that in the file. The first instance will include the term “initramfs-linux.img”. There you will add “/intel-ucode.img” in front of it so it looks like:

initrd /intel-ucode.img /initramfs-linux.img

5. Save the grub.cfg changes and restart…you should be back up with everything up to date.

Thanks, I did it, and when I run:

  
dmesg | grep microcode

I got result:

[ 0.000000] CPU0 microcode updated early to revision 0x29, date = 2013-06-12  
[ 0.138001] CPU1 microcode updated early to revision 0x29, date = 2013-06-12  
[ 0.480101] microcode: CPU0 sig=0x206a7, pf=0x10, revision=0x29  
[ 0.480115] microcode: CPU1 sig=0x206a7, pf=0x10, revision=0x29  
[ 0.480216] microcode: Microcode Update Driver: v2.00 <tigran@aivazian.fsnet.co.uk\>, Peter Oruba

So, this means that it works, doesn’t it?

lots.0.logs, how editing of grub.cfg file works in Antergos?
When I tried right click on file name and open it in text editor, permission was denied. And I don’t see option “Open folder as Administrator”. If this tread is not a place for this, maybe in separate thread?
Thank you.

nekosan: it looks like people who have PC with Intel processor have to do that manually: enter first command in Terminal, and edit grub.cfg file through text editor. I’m not qualified to advice about anything in Antergos, this is how it would have worked in Linux Mint.

The command:

sudo gedit "/boot/grub/grub.cfg"

Would give us sufficient right to edit it (as administrator).

Thank you.[/quote:217j1e64]You can open as root using this command[command:217j1e64]sudo -E gedit /file/to/open[/command:217j1e64]
If you want to get it done quickly, you could just copy/paste the sed command from my previous post

I also have doubts. Is this even necessary?? Yes, I have an intel CPU, just like almost everyone, but my laptop has been working fine and I haven’t installed intel-ucode. What it does? Should I install and make the grub changes??
