While looking into it I found this guy wanting 64 MB swiotlb who was probably doing something like that: https://stackoverflow.com/questions/52833714/change-the-size...

Looks like an exception to the rule, though.

I've worked on a project that required a bigger swiotlb as well, I don't remember the exact details though. I guess it's not that uncommon, but indeed the default value looks good.
