I am not familiar with cryptsetup > plain. What benefits do you see with this over direct dmsetup? cryptsetup is the de-facto standard to setup encrypted block devices. There is a lot of existing tooling around cryptsetup already (systemd, etc..), so being able to use CAAM keys for dm-crypt with cryptsetup seems natural to me. Plain mode allows setting up dm-crypt without LUKS. Thanks, //richard
