intel microcode?

amd-ucode was merged with linux-firmware, but why do we still have a seperate intel-ucode ? —This unsigned comment is by Stefanwilkens (talk) 13 October 2013 14:14. Please sign your posts with ~~~~!

Presumably because the sources are different: [1] [2] -- Alad (talk) 01:14, 16 October 2015 (UTC)

Live Arch

No problem with this addition on a live system that can switch between intel and amd microprocessor? Lacsap (talk) 08:41, 28 October 2014 (UTC)

You have both an Intel and AMD CPU? Are you sure you're not talking on hybrid graphics? -- Alad (talk) 02:30, 16 October 2015 (UTC)

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)
