need this but still, not even 5.1.11-300.fc30.x86_64 would boot.
I want to ask you guys if your Ryzens (APUs) are good and do NOT need
that option?
I don't have that hardware, but I took a look at the configuration for
kernel 5.2, and I see AMD_IOMMU and AMD_IOMMU2 available as
configuration options. 5.2 is about half way through the testing
cycle, so will probably be available in stable versions in a month or
two (maybe three).
You could check whether your kernels have it turned on by doing a grep
for it.
grep -i amd_iommu </boot/config...>
