Re: [PATCH 0/3] powerpc: Instrument Hypervisor Calls

Not sure I follow you. I would expect the PURR value to be restored after
a context switch, even if we continue on a different physical CPU.

The idea behind monitoring both PURR and timebase is that the difference
between the two tells you how long the partition was suspended during
the hcall.

Sounds good, last time I looked at the patch I thought it was gathering
the PURR only. That on its own would make for some confusing results.
