Thanks.
I don't have any substantive comments (apart from "oh, you're supposed
to grovel over a registry key to get the cpu information, nice :(").
Brian,
I think you're much more familiar with this area of the code than me.
Please chime in if you have any comments!
Thanks Jon,
Never received the original patches in my email, so imported all from p-
i, and will have a look soon, comparing against x86_64 and Linux-next
x86 and arm64 cpufeature enumeration and cpuinfo output.
It would be easier if MS Windows also exposed elevated CPU and MSR info
to regular user space.
Brian,
Just a gentle ping to follow this up. Any comments or "looks good"?
