    Secure Memory Encryption SME on Ryzen 5 (mobile) !?


      Hi there,

      I have a Ryzen 5 mobile, precisely Ryzen 5 2500U.

      When looking at the output of lscpu I noticed that little sme CPU flag.

      Very interesting! sme flag is Secure Memory Encryption.

      I thought SME is only available for enterprise CPUs?

      Is SME actually usable on Ryzen 5 (mobile)?

      I once enabled SME on a kernel 4.15.something, but my machine froze, did not boot with sme enabled.
