Not sure if Manish got back to you or not.  Saw this message go by on a 
mailing list (IBM internal one) and thought it might relate to what you 
were asking about.  If it does you might post to 
linuxppc64-dev at and ask about /proc/ppc64/lparcfg containing 
PURR data.

Come to think of it that mailing list might be a good place to get your 
kernel questions answered.

/proc/ppc64/lparcfg has recently been amended to include cpu (PURR)
usage. It might not be a feature in either of the distros yet. Jeff
Scheel might now.
