    Hold up, since when did consumer Ryzen CPUs have memory encryption support? I was sure that was always a EPYC exclusive feature.

      I think that’s the crux of the article. The feature was there on some chips but not supported. A new update now prevents access to the feature.

    YSK: This feature was disabled with a pushed firmware update.

    Its true it was “not supported”, but the CPU was/is capable of it.

    The big issue here is did AMD disable it accidentally, or did they do it intentionally. If it was intentional why did they not announce it anywhere in the update notes, or anywhere else?

    It’s funny how every big tech decision these last few years all sound like a shitty James Bond villain step in a shitty world domination plan, with shitty corpo writing.
