> Amusingly, while implementing support for this in Linux, we ran into a bug in Linux’s ARM SMMU support that had been there ever since 52-bit address support was introduced. This was breaking systems with more than 256 TiB of RAM - I wonder why nobody noticed? Either way, Linux now correctly supports standard ARM systems with up to 4 PiB of RAM ;-).
Interesting how working on new technologies helps improve existing things for all users. Sort of reminds me how NASA invests in R&D and those investments eventually come back to military and consumers.
