I think that is something that only can be answered on -dev.
Personally I think xenpm show cpu topology has worked for me on 3.x +
4.1.x but as it comes from memory thats not worth a lot.

Hi - Dimitar,

can you test the patches?
I don't have a build box or anything running current enough software
at the moment.
(I'll probably not make that version jump before end of the year...)
I can do it in 2-3 weekends from now but by then I'll have forgotten :(

Greetings,
Flo
