Power efficient userspace waiting with the umwait x86 instructions > > More description is here: > https://lwn.net/Articles/790920/ It is a shame that: - will only be available on new Intel Tremont micro-architecture CPUs, whenever they ship - will not be available for AMD CPUs, the new ROME/EPYC 2 CPUs are kicking Intel's offering - will not be available via Windows API for some time I think it is worthy to create a JIRA ticket for this issue, but believe that it should not be implemented until Windows API support is available at the very least. The articles don't mention what if applications would need to detect if umwait is implemented/active, and implement alternate logic if not, or will OSs need to have a default implementation for incompatible CPUs.
