CPU microcode loading support for custom kernel

Is the section Microcode#Enabling Intel Early Microcode Loading in Custom Kernels still relevant when initrd /intel-ucode.img is added to the Gummiboot options? -- Gim (talk) 09:42, 1 November 2014 (UTC)

Passing parameters with refind

With this edit User:Vesz deleted "/boot/" from parameters. Is this correct? Because in the following paragraph there is explained to use initrd=/intel-ucode.img or /boot/intel-ucode.img as required. As you can see, there "/" symbol is used before "intel-ucode.img". — Agent0 (talk|contribs) 20:21, 20 February 2015 (UTC)

I have only tried using it without a /, and it works. I assume that it might work with a / as well but I haven't confirmed it. Either way it seems that if you have a separate boot partition it's wrong to enter the path in a root-filesystem format. I don't have access to the system in question right now so I can't try with a leading /. Vesz 21:09, 20 February 2015 (UTC)

Disable microcode updates

Is there any way to disable microcode updates? We have had trouble with failed microcode updates in VMs so it would be great if it were possible to disable them (for AMD in this case)

The answer to your question is clearly articulated in the main article. Graysky (talk) 15:18, 3 January 2016 (UTC)
No it is not, the page deals only with enabling, not disabling microcode updates. For Intel it can be disabled trivially (you just uninstall intel-ucode), but since for AMD the updates are available in linux-firmware and applied automatically, disabling it is not clear at all. -- Lahwaacz (talk) 20:06, 3 January 2016 (UTC)

Please remove the following paragraph

Warning: This file will automatically be overwritten by /usr/bin/grub-mkconfig during certain updates negating the changes. It is strongly recommended to use the configuration directory in /etc/grub.d/ to manage your GRUB configuration needs.

This paragraph must be removed because grub now recognize the presence of intel_ucode.img in /boot.

That's why there's Microcode#Automatic_method. The warning says that the grub.cfg file would be overwritten by grub-mkconfig, which is still true. -- Lahwaacz (talk) 14:39, 28 October 2016 (UTC)
