Hi Bill,
I am trying to see variation in processor speeds (SPURR PURR values needed) with change in Power Mode of a P7+ thorad 48 cores system on PowerLinux (RHEL 6.4), but " lparstat -Ew " doesn't seem to work. Is there a rpm build for the same that needs to be installed?
whereas on AIX it works fine as below

 
# lparstat -Ew 5
 
System configuration: type=Dedicated mode=Capped smt=4 lcpu=192 mem=255488MB Power=Dynamic-Power
 
Physical Processor Utilisation:

Sorry, missed this comment. I thought I would've gotten an email notification of a new comment..

 
I'm now told the lparstat command is more along the lines of a technology-preview.. and we can work through defects and testing of this as people ask questions. I'm not sure everything from AIX will be implemented, but we can start the process now. We'll create a wiki page to track progress and questions.
