I seem to recall seeing something to that effect, to prevent things like Row-hammer.
I guess I was not sure of the documentation in terms of Qubes 4.1 versus other possible configurations, so I thought I would ask. The note I recall was about interleaving of Core, which I guess also means interleaving of RAM. Also, what about, main processor having its own channels directly to RAM, rather than riding the Bus. Does Qubes 4.1 utilize this?
If I was purchasing a laptop, that offered several different Main Processor Cores, I would not want to purchase more than I could effectively use and be secure.
