You bet I was as I'm working on Moblin;-) However, some work while some do not. I'll take a look at the problematic ones. With the previous event and umask values, the pmc does not count at all for some events, like l1d-write-ops.
Btw, one thing I don't quite understand is why you aliased dtlb-write-ops to l1d-write-ops when setting event and umask values. Are they the same event?
Thanks -Yong
