This is interesting; i don't really know the history behind our piece of code; as far as i understand, we have a shared ring buffer with userspace, onto which we push tracing events, and we must mark it as encrypted when the kmod runs on an AMD SME enabled kernel to allow userspace to grab sane data. This is the commit that introduced the change (if you wish to give it a look): https://github.com/falcosecurity/libs/commit/0333501cf429c045c61aaf5909812156f090786e Do you see any workaround not involving `pgprot_encrypted` ? Thank you very much for your answer, much appreciated! Regards, Federico
