But the performance numbers almost look like swiotlb=force got ignored before (even if I can't explain why). Do you get a similar performance with the new kernel without swiotlb=force as the old one with that argument by any chance?

I'll see if I can test that, as I am not sure I have control over those cmdline arguments. Cheers, Nathan

Pass a bool to pass if swiotlb needs to be enabled based on the addressing needs and replace the verbose argument with a set of flags, including one to force enable bounce buffering. Note that this patch removes the possibility to force xen-swiotlb use using swiotlb=force on the command line on x86 (arm and arm64 never supported that), but this interface will be restored shortly.
