It looks like many Linux distros require x86-64-v2 from 2008 and they're preparing to move to v3 from 2013. At this rate they'll never support a level with expired patents. https://en.wikipedia.org/wiki/X86-64#Microarchitecture_levels https://en.wikipedia.org/wiki/X86-64#Microarchitecture_level...
- crote 1y agoConsidering there are no meaningful patent-free x86 CPUs in the wild, why should they? It's just the default optimization level for those distros. If patent-free x86 CPUs become relevant, compiling another set of binaries would be trivial. Until then it doesn't make any sense to kneecap the >99% of x86 deployments by deliberately refusing to use faster and more efficient instructions.

- wmf 1y agoThat's a fair point. I guess a bigger problem is that a patent-free x86 processor couldn't run any supported version of Windows.
- jacquesm 1y agoThat's the last thing I would want to do.
