> Subject: [PATCH v7 03/10] eal: add intrinsics support check infrastructure
>
> Currently, it is not possible to check support for intrinsics that are
> platform-
> specific, cannot be abstracted in a generic way, or do not have support on all
> architectures. The CPUID flags can be used to some extent, but they are only
> defined for their platform, while intrinsics will be available to all code as
> they
> are in generic headers.
>
> This patch introduces infrastructure to check support for certain platform-
> specific intrinsics, and adds support for checking support for IA power
> management-related intrinsics for UMWAIT/UMONITOR and TPAUSE.
