* Dave Hansen:
That's kinda my whole point.
These *MUST* be curated to be meaningful. Right now, someone just
dumped a set of CPUID bits into the documentation.
The interface really needs *three* modes:
1. Yes, the CPU/OS supports this feature
2. No, the CPU/OS doesn't support this feature
3. Hell if I know, never heard of this feature
The interface really conflates 2 and 3. To me, that makes it
fundamentally flawed.
That's an interesing point.
3 looks potentially more useful than the feature/usable distinction to
me.
The recent RTM change suggests that there are more states, but we
probably can't do much about such soft-disable changes.
Thanks,
Florian
