I chuckled when I first read this, as if people would disagree - "no, I don't think we want to have an API to return accurate information about hardware capability". One thing to keep in mind is to ensure that it's extensible so that non-intel features can be detected as well. Easy portability is key.
Of course, since this is only an API issue. It will cover the vendor-specific information underneath. Along with more and more multi-processor/multi-core/multi-thread platforms available from almost all major processor vendors, it is time to have a proper API for the runtime, unless we give the burden to users with command line options. Well even that, programming-wise we want an API to keep the command line options. Thanks, xiaofeng
