I am trying to edit the kernel parameters during runtime to set intel_iommu to =on. However I cannot find any documentation anywhere on how to do so with only Manjaro on my system (a lot of (the very few) forum posts I see about doing this talk about dual booting). I’ve tried using sysctl but to no avail (unless I was using it incorrectly with this parameter).
