To be fair, that email is from 2007. Did x86 processors have nested page tables back then? If not, he might have been complaining about that.

- sudowhodoido 12y agoNo they didn't have SLAT/EPT then. That came in with the i-series processors. The processors were knee deep in errata and buggy as hell. As they are now: http://www.intel.co.uk/content/dam/www/public/us/en/documents/specification-updates/xeon-e5-family-spec-update.pdf http://www.intel.co.uk/content/dam/www/public/us/en/document... Intel don't do a good job of design or engineering really. That's going to sting, I know. I'd love to see 64 bit SPARC make a comeback TBH. Proper hardware contexts/threads, more registers, a decent MMU etc.
- justincormack 12y agoIts called arm64... the first new modern RISC design for a long time.
- sudowhodoido 12y agoGood point! I'd completely forgotten about arm64.
