Maybe but linguistical semantics is not the point here. The idea is to represent a "binary" concept of memory being encrypted or memory being not encrypted. And at the time we decided to use "encrypted" and "decrypted" for those two things. Do you see the need to differentiate a third "state", so to speak, of memory which was never encrypted? -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
