Re: [perfmon2] [PATCH] 0/6 "Catch up" patches for POWER4/4+, POWER6

[Corey A. <cja...@us...>]

Hello Takashi,

I tried out your patch and it appears to clear up some problems with multiplexing that
I was seeing.  I still have a problem with measuring Int instruction events in a multiplexed
event set, but overall the behavior is much improved now.

Thank you.
